Threading Leaves (and so Much More!)

This activity seems quite simple (and it is) but your child can gain fine motor skills, learn math, and even learn about natural science! Plus, you will need a nice outdoor walk by a park or forest near you to collect these beautiful autumn leaves to begin with, which gives you and your child a chance to connect with nature! Take a camera for your child  to photograph all the leaves, the trees where you found them, the beautiful scenery around you (an excellent visual arts activity), and take the time to play and jump on the biggest pile of leaves you can find (gross motor play) and feel how the weight of your child’s body makes them crackle (sensory learning). We love using nature to learn at our CEFA Early Learning schools.

You can do this anytime of the year, but fall is my favourite as the leaves are so colourful. Give it a try at home!

Best Ages for This Activity

One to five

How to Make It

You Will Need:

  • Assorted leaves that you collected outside
  • A small branch to thread the leaves through (see activity photo)

Let’s get Started

  • Go on a walk outside and take the time to play with leaves before you collect them (optional). During play, ask your child about the way the leaves feel on their hands, or how they sound when they walk over them. Chat about the scents of fall, the colours they see, the shapes of the leaves, the size of the trees and of the leaves, the different sorts of leaves and trees they find, etc. Don’t “quiz” your child, just talk about these things as if you were chatting to a friend about it. These types of conversations are the ideal way for your child to increase their vocabulary as well as their math language and math knowledge. Your child will also learn about nature, about why the leaves fall, about the trees and how many years it takes for them to be as tall as they are (if you are not sure, Google is your friend here). Explore, explore and explore. Enjoy nature with your child and they will develop a lifelong love for the outdoors, and respect for the natural world. Don’t rush this part of the activity – fully immerse yourself in it!

  • Take the time to take beautiful photos (on your phone is perfect) show your child how to look through a lens, how to capture what they find beautiful through a photograph. This will make a perfect visual arts activity!
  • See if you find any friends amongst the leaves and find out how they live. You will at least find a few interesting insects

  • In a basket or recyclable bag, collect your favourite leaves to take home, and one twig or tiny branch (that has fallen – don’t rip from a tree). This will be to weave the leaves through. The more firm it is, the easier it will be for your child to weave. The more flexible, the more challenging (or frustrating, depending on your child’s fine motor skills level).

  • When you get home, look at all the leaves you found! This is where you could introduce math activities such as:
    • Counting the leaves
    • Sorting by colour
    • Sorting by size
    • Sorting by type/shape
    • Sorting by level of dryness
    • Etc.

  • Invite your child to thread the leaves through the branch you collected. This can be done any which way your child chooses, focusing on the beauty of the final product. It can also be an opportunity to learn math by sequencing the leaves:
    • one red leaf, two yellow leaves, one brown leaf, one red leaf, two yellow leaves, one brown leaf, etc.
    • one large leaf, one medium leaf, two small leaves, one large leaf, one medium leaf, two small leaves, etc.
    • one maple leaf, one arbutus leaf, one maple leaf, one arbutus leaf, etc.
    • the possibilities are endless here! You can even have several little branches each with a different colour leaf!
  • Threading the leaves is an excellent fine motor activity, as your child has to be delicate enough not to break or rip the leaf, which requires skill.

Learning Opportunities

Children will learn so much with this activity, including fine motor skills, math, creativity, art, S.T.E.M., natural science, literacy, independent play and so much more!

Extended Learning Opportunities

  • Make a beautiful leaf collage (visual arts)

  • Make a leaf garland and teach your child to tie knots (fine motor skills and practical life skills)

  • Learn about the trees and leaves in your neighborhood, and about why leaves change colour (natural science, nature appreciation) and classify them (math).

  • Make a beautiful leaf mobile (visual arts) for a baby brother or sister (empathy and contribution)

  • Paint with leaves (visual arts and sensory activity)

  • Learn to draw the different leaves (art, math, fine motor skills – a precursor to writing)

  • Colour match (math)

  • Make graphs of your findings (math)

  • Make your leaves come to life! (dramatic arts, creative play and art)

Why is Sensory Play Important in the Early Years?

From birth and throughout early childhood, children use their senses to explore and make sense of the world around them. As adults, we sometimes forget that it is often our child’s first time tasting something (your family’s famous spaghetti Bolognese), smelling something (the wet soil after it rains), hearing something (an owl in the middle of the night), feeling something on their skin (a snowflake landing on their nose) – children discover the world by exploring it with all their senses.

What are the Senses?
Senses refer to the different ways we perceive the world. Our brains use many senses but the five most common ones are sight (the stimulation of light receptors in our eyes, which our brains then interpret into visual images), hearing (the reception of sound, via mechanics in our inner ear), taste (the stimulation that comes when our taste receptors react to chemicals in our mouth), smell (the stimulation of chemical receptors in the upper airways – the nose) and touch (the stimulation that comes from touch receptors in our skin that react to pressure, temperature, or vibration). We also include body awareness (also known as proprioception – the feedback our brains receive from stretch receptors in our muscles and pressure receptors in joints which enable us to gain a sense where our bodies are in space) and balance (the stimulation of the vestibular system of the inner ear to tell us our body position in relation to gravity).

The more senses your child engages during their learning, the better they become at executing more complex learning tasks and support cognitive growth. Sensory learning supports language development, body awareness, gross motor and fine motor development, social interaction and problem-solving skills, to name a few.

Because it is important that children experience and explore the world with all of their senses, psychologists, learning therapists and educators (especially early learning experts) have developed sensory activities specifically designed to enhance sensory learning. They are activities in which your child’s senses are engaged and stimulated (including activities that engage movement and balance).

You will find that, at home, you also provide these opportunities for your child. For example, when your child plays in the bathtub, or plays with mud in your backyard, or washes dishes – they are engaging in sensory learning.

Sensory play is important because it plays a role in your child’s brain development. Our brains have trillions of brain cells called neurons. We learn when these neurons connect to one another. These connections are called synapses. In the first five years, your child’s brain grows more than at any other time in their life, as explained in this article. An infant is already born with about 50 trillion synapses, but by age three, these have grown to 1000 trillion!

The more opportunities your child has to learn, the more synapses are formed between neurons. By the time your child enters elementary school, the neurons that have not connected to one another (formed synapses) are pruned. That is why I am such an ardent advocate for early learning: it is when your child is developing the brain they get to use for the rest of their lives! That is also why created our CEFA Early Learning schools and carefully developed its curriculum: to offer an environment perfectly designed for your child to learn in various essential ways (not just the typical ways we associate with learning, like reading, or listening to a teacher). One of these ways is through sensory learning.

Sensory play is essential for your baby from the moment they are born, and also through the early years: it is one of the ways your child’s brain develops. It strengthens sensory related synapses and functions. Exposing your child to diverse sensory experiences is needed for their maturing brain to develop the proper sensory processing capabilities. The early years are especially important for exposing your child to sensory learning because many of these senses develop optimally (if not only) during a window of time called “critical period”. In other words, if your child is not creating these synapses in the early years, they will not be created later in life – that “critical” window of time to create them will have closed. Sensory play is essential for newborns, babies and young children (which is why an early learning centre cannot only offer worksheets, teacher-led “lessons” or be an extension of elementary school). It is very important that your child’s school be well versed in the way your child’s brain develops, at a neurological level. Otherwise, the program offered will be lacking it essential elements like sensory learning. If your child does not attend an early learning school, you must, as a parent, ensure that you provide plenty of opportunities for your child to learn through all their senses at home. The brain they are building in the early years is the brain they will have to work with for the rest of their lives.

Research has also shown that sensory play is important for elementary school children. I personally feel that elementary schools are lacking in this area, and that parents should supplement their child’s sensory learning at home. Go out and play in the rain, cook together, taste all kinds of food, play with goop and rice and slime. Many of the activities offered here on my parenting site are great for older children too. More importantly, make sure that your child has time to play, cook, wash the dishes, and do regular things rich in sensory stimulus. Even adults retain more information when they engage multiple senses while learning.

Top 5 Reasons to Include Sensory Play in your Child’s Day:

1
It builds neural connections in the brain, leading to more complex learning tasks and a more developed brain, for life.

2
Learning through multiple senses enhances memory and cognitive growth.

3
Helps your child self-soothe and find calm, develop coping mechanisms and reduce anxiety or frustration.

4
It supports language development, including mathematical language (especially attributes like hot/cold, smooth/rough, wet/dry)

5
It enhances gross and fine motor skills development, spatial awareness, problem-solving skills and social interaction.

If your child attends our CEFA Early Learning schools, you do not have to worry about providing enough sensory experiences at home – most of our activities, even the ones we plan for writing, reading and S.T.E.M., have a rich sensory component to them, and children have plenty of time to play freely in a classroom that is especially designed as a sensory rich environment. If your child is too young or too old to attend CEFA Early Learning schools, or if there is no school in your area, do not worry! Most of the free activities I share with you on this website are sensory rich. For activities designed specifically for sensory learning, try these sensory games. There are so many more activities you can do with your child that engage the senses, and every week, I am adding more activities for you to explore with your child. Also, you can add sensory learning by thinking of all the ways your child’s (and your) senses are activated: listen to the birds singing during your next nature walk, or jump on a puddle or in a pile of leaves and hear and feel the experience! Play with dough at home, or cook together and taste, smell, feel the different foods on your fingers and in your mouth. Listen to different music together, dance to it. Balance on a log, climb, swing, jump, run! Feel how the different fabrics feel: your clothes, the cushions, the couch – children love to run their fingers through your new super soft (but dry clean only) wool sweater – do it in the name of sensory learning.

As you play, help your child engage all their senses by talking about it. This is also excellent to develop your child’s vocabulary and language skills. For example, ask your child how things feel (How does the wind feel on your face? Do you like the smell of this orange? Do you like the colour of the pomegranate? How does it feel between your fingers when you seed it? Can you see through it? Can you hear it pop in your mouth when you eat it? What does it feel like? Does it feel different than eating an orange? An apple? A grape? Etc.). The idea is to invite your child to use as many senses as possible throughout the day during normal activities. Also, children naturally engage their senses during play if you just give them time and the opportunity to try, so go on – live a little and welcome a mess from time to time!


Sensory Math with Marbles: One to One Correspondence

Sensory exploration is essential for young children, as they learn through their senses. I explain why in this article. This is an activity that is also used in art therapy with young children. At our CEFA Early Learning schools, we use it to teach an essential math concept to our youngest students: one on one correspondence. In mathematics, one-to-one correspondence refers to a situation in which the members of one set (call it A) can be evenly matched with the members of a second set (call it B). In this case, there is one marble for every one dot of paint.

This activity is very simple and inexpensive for you to do at home and I guarantee your child will enjoy it immensely! Give it a try and let me know how it goes in the comments below.

Best Ages for This Activity

Zero to three

How to Make It

What You Will Need

  • Marbles (these different colour ones will allow you to do the activity extension below as well) – you can get these at the dollar store or supermarket as well. You will have to stay close to your little one as they present a choking hazard.
  • A lid or other container so that the marbles don’t roll to the ground covered in paint
  • A blank sheet of paper
  • Non-toxic paint of one or more colours (make sure the colours also have the colours of the marbles if you want to do the activity extension.)

Let’s Get Started!

  • Set up the paper as per the picture, adding several drops of paint. Prepare a little basket, cup or containers with marbles to have by the side of the paper.
  • Invite your child to play a math game. You can say: “in this game, we place one marble on one dot of paint” and encourage your child to try. If they do not know what to do, demonstrate with one marble.
  • Stay close and supervise as it poses a choking hazard. Each time your child picks up a marble, you can say “one marble” and when they place it on the dot of paint you say “on one dot of paint” Children love repetition – celebrate each marble your child corresponds to a dot of paint! You can clap, kiss, do whatever you like!
  • If your child wants to continue after all the dots have been covered, you can add more dots of paint to the same paper (this will be a great fine motor skills practice for your little ones because the more dots and the closer together, the more it works on their fine motor skills and hand-eye coordination. Otherwise, start a new sheet J
  • Look at the extended learning opportunities below to extend this activity!

Learning Opportunities

Children S.T.E.M., particularly math. They will also practice the fine motor skills necessary for writing and fine movements. This is also an excellent sensory learning activity and has an art therapy and meditative, calming component. Encourage your child to describe how it feels to place the marble on the paint for added vocabulary and sensory awareness.

CEFA tip: Supervise at all times!

Extended Learning Opportunities

  • Once your child has placed all the marbles, encourage them to make a painting by moving the box lid so the marbles roll off the paint and all over their sheet of paper, making a painting like the image below. It will also teach your child the science of how the control of items creates a reaction (physics).

  • If your child likes the activity, try it again also corresponding each colour of marble to each colour of paint dot. You would then say: “one orange marble on one orange dot”. This is added math learning.

Brain Development in Your Child’s Early Years

Did you know that from the time your child is born until age five, their brain develops more than any other time in life? So much so, in fact, that by the time your child reaches kindergarten, 90% of your child’s brain is already developed.

Compare this to how our bodies grow: at birth, we are merely a few pounds and we keep growing until well into our teens, where we finally reach our adult height. If our bodies grew like our brain does, a child entering kindergarten would only be a few inches off their final height, with only 10% more growth to go.

This is why it is so important to ensure that our children have plenty of opportunities to learn in their first five years, as well as the right type of stimulation.

The quality of your child’s experiences at that stage will shape how their brain develops for the rest of their lives. Your newborn baby already has all of the neurons (brain cells) they will have for the rest of their lives, but learning depends on those neurons connecting to one another.

If you look at the picture on the left, you will see a synapse (or connection) between two neurons. It is that synapse, and thousands of other synapses that your child forms while playing, learning and interacting with the world around them, that your child learns. The more synapses, the more your child’s brain has established learning pathways. The more brain cells connected, the higher your child’s ability to learn for life. It is the connection between your child’s brain cells that really make the brain work.

Your child’s early years are a crucial time for making these connections. , which is more than any other time in life. These connections allow your child to learn to walk, jump, run, speak, read, write, reason, understand emotions, and basically anything else a fully developed brain can do. Brain development builds on itself as connections link with each-other in more complex ways. For example, a child will learn to walk first, then learn to run, jump, dance, or other activities that are connected to learning to walk. A child who is given plenty of opportunities to make connections, will continue to build upon these connections, and is able to move, think and speak in more complex ways over the years.

Your child’s first years are the very best time to develop the connections they need to be capable, healthy and successful adults. The connections needed for important higher-level activities like self-regulation, problem-solving, motivation and communication are all formed in the early years. It is much more difficult for those connections to be formed later in life, and sometimes, it is almost impossible. For example, learning to talk. If a child is not exposed to language during the early years, it is believed, based on case studies such as Genie’s and Victor of Aveyron, that if a child does not learn to speak during early childhood, they will not be able to acquire a first language for the rest of their lives.

How Does My Child Build Brain Connections?

Starting from birth, and maybe even in the womb, children develop brain connections through their everyday experiences. These connections are built through interactions with their families and the people they are exposed to (teachers, extended family, etc.) as well as by discovering the world around them (trees or birds they see, different textures and smells they are exposed to and can interact with, etc.) your child’s daily quality experiences will determine which brain connections are made, and which will last for a lifetime. This is why the quality of care and education they receive in the first five years directly determines how much and how well they will learn for the rest of their lives.

How Can I Help My Child Build Brain Connections?

The best way to help is by being responsive. From birth, your child serves up invitations to engage with you. Babies do it by cooing, smiling and crying, for example. Toddlers can communicate their needs more directly. Regardless of your child’s age, think of each of these invitations as an opportunity for you to be responsive to your child’s needs. It is called “serve and return” – they serve, you return. You will also notice that when you serve, they learn to return! Keep in mind your return to their serve is fundamental to the wiring of your child’s brain.

By giving attention when your child “serves” you the opportunity, by responding and interacting with your child, you are hugely helping to build your child’s brain. Here are other times you are helping your child build strong neural connections:

  • When you converse with them

Instead of talking to them, talk with them, have a conversation, invite them to participate in that conversation. Sometimes we tend to keep it a bit too simple and most of our conversations with baby tend to become orders that don’t invite your child to respond (pick up your toys, wash your hands, come and eat dinner).  Instead, no matter how young they are, make it an engaging conversation that invites them to participate (Would you like to help setting the table for dinner? How many plates should we set? Will we need spoons? Cups? Which cups do you think we should use? The tall ones or the shorter ones?) – this not only greatly enriches your child’s vocabulary (neural connections), it also teaches them to make choices (neural connections) learn math by comparing and counting (neural connections) and learn to contribute to your daily life which is very important for your child’s self-esteem and sense of self-worth. The more you get used to speaking with your child like you speak with your spouse, friends or co-workers, the more your child is making – you guessed it – neural connections.

  • When you play with them

Again, be very open-ended and inviting during play, and ask questions or invite suggestions. Find activities that invite your child to use their imagination and creativity, like the ones you will find on this site (here)

  • When you sing with them

You can teach your child new songs (vocabulary, music, gross motor skills if you dance too!) and you can teach them rhymes and fingerplays, which  are great for learning at a young age, as your child is actively following along.

  • When you read with them

When your child is very young, you will be doing most of the reading, but you can also play with them while reading by using what is on the page to teach them words or repetitive actions. For example, you see bubbles on a page of the book, and stop with excitement to say “I see bubbles! Look! Do you want to pop the bubbles? Let’s pop the bubbles (then direct their finger towards each of the bubbles saying “Pop! Pop! Pop! Pop!) all of these explorations are part of learning to read, so don’t worry too much about getting to the end of the story. When your child is older, you can take turns choosing the books (or choose one each) or reading to each-other. This article I wrote will give you more tips for reading with your child and you will find a few more articles, depending on the age of your child, here.

  • When you go on walks and explore nature together

This article [https://www.parentingwithnatacha.com/great-outdoor-activities-for-the-body-and-the-brain/] can give you ideas and tell you more about the importance of connecting with nature for children and the whole family. I have also included a few more articles about playing outdoors in this collection

  • When you include them in your daily routines

Cooking, cleaning, laundry and baking are all activities that can be done with your child, and that your child can greatly learn from. They will learn S.T.E.M. when preparing a recipe with you, as well as vocabulary and essential self-help skills. They will learn math when sorting laundry and figuring out its sequence (first we separate colours, then we add the right amount of soap for the load, then we wait 40 minutes while it gets washed, then we put it in the dryer, then we fold it when it is dry, then we sort it) and fine motor skills when helping you fold. For more activities you can do with your baby at home, have a look at this article  and a few more in that collection.

By talking, reading, singing, exploring and working together from the day your baby is born, and by responding to their “serves” consistently, you are helping your child form new neural connections. Also, give them opportunities to explore their physical world at their own pace, and provide a safe, dependable and nurturing environment for your child.

This applies to all the people your child spends time with, from grandma to their teachers at school. Your child’s relationships with adults in their life are very important influences on their brain development. The more loving, responsive and dependable, the more your child’s brain can flourish, and as a result, the more successful your child will be not only in school but in life.


How to Make Pumpkin Slime

Children learn through their senses and this activity is perfect for sensory play and exploration. Plus, if your child makes the slime, it is a great S.T.E.M. activity, especially for learning math and science! If you are already carving pumpkins for Halloween, why not use the insides to make this easy activity?

I especially recommend this activity for you to try at home this year since our CEFA Early Learning schools are not making any slime or other sensory recipes that your child can sink their hands into, due to COVID-19 (it is hard for children to not want to share). This is easy to make (you can do it in less than five minutes), rich in learning and will last you at least until Halloween!

Best Ages for This Activity

One to five

How to Make It

Ingredients

  • A pumpkin (a smaller one is fine)
  • ½ cup water
  • ¼ cup liquid starch
  • ½ cup clear washable school glue – Elmer’s glue works better than other glues.
  • A measuring cup
  • A washable bowl or container (glass is best as we will be mixing glue)
  • A pumpkin carving kit (you can also get these at the dollar store. Or if you don’t plan to carve your pumpkin for Halloween, just a spoon and knife is fine.)

Let’s get Started!

  • Invite your child to use the guts of the pumpkin to make pumpkin slime (or pumpkin guts J)
  • Cut the top off your pumpkin (you will need to help with this step, for your child’s safety)

  • Using their hands, or the pumpkin carving tool, or even just a spoon, your child can scrape the insides of the pumpkin, taking out all the inside (seeds, fibre, etc.)

  • Invite your child to measure ¼ cup of liquid starch, then pour it into the pumpkin.
  • In a bowl, mix ½ cup of glue with ½ cup warm or room temperature water until it is well mixed. Pour it into the pumpkin also.
  • Measure 1 cup of the pumpkin “guts” (strings and seeds) and pour back into the pumpkin.
  • Invite your child to mix everything very well, using their hands. This is a fun sensory activity and a chance for your child to experience how the substances change as they mix together.
  • Once you have a uniform mixture, invite your child to knead the slime. You can do this inside the pumpkin or take it out and knead it on a table. Kneading it will improve its consistency. You can simply pick it up with your hands. For best results, try adding a few drops of the liquid starch onto your hands before picking it up. Not too much, or else your slime will become stiff instead of stretchy. This is what it will look like after just a few minutes of handling it:

  • Enjoy playing with the slime! Ask your child how it feels on their hands, how it smells, what the texture reminds them of, etc. (this will work on their vocabulary). Ask your child if the slime feels like a liquid or a solid to them (if they are young, give them examples, like this: “does the slime feel liquid like water, or solid like this elastic band?). Is it more or less liquid than the glue? You can share with your child that slime is not quite a liquid, but it is not quite a solid either – it is called a “non-Newtonian fluid” because it is a little bit of both.
  • Try counting how many seeds are in the slime (math), what colour it is, how long they can stretch it for, etc. – these are all math concepts to explore. You can even use a measuring tape or a ruler to measure how far you can stretch the slime!
  • Talk about where the pumpkins came from, about how to grow a pumpkin and about where the best place to plant them is (you can use the seeds from those very pumpkins to plant your pumpkins for next fall). This will teach your child about nature, the cycle of life and science.
  • To teach life skills, you can roast the rest of the pumpkin seeds (the ones that you did not add to the slime) to eat them later as well.
  • Carve the pumpkin after you made the slime if you wish, for an added learning activity. This will teach your child life skills as well as provide a chance for practicing fine motor skills (essential for writing.) It is also a great way for your child to express their creativity!

Learning Opportunities

Children will learn life skills as well as natural science. They will learn S.T.E.M., particularly math and science. If you plant the seeds, they will learn about gardening and about where our food comes from. This will develop an appreciation for food and what it takes to grow it. They will practice fine motor skills by using their wrist and hand movements to mix, cut, scrape, carve, empty and knead. Through play, they will learn new vocabulary as they describe their experience and math vocabulary when measuring and comparing. This improves their literacy and math skills. This is a really good sensory activity as well.

The Science Behind Slime

The glue is a polymer. Polymers are made of long, identical and repeating strands of molecules. These molecules flow past one another, keeping the glue in a liquid state. But, once you add the borate ions (which are contained in the activator you use – in this case, the starch), it starts to connect the long strands of molecules of the glue together. These connected strands start to mix together and get tangled up and even longer and that is why it feels less like a liquid and more like a viscous slime – more rubber-like to the touch and thicker. Slime is a polymer.

Ghost Egg Science Experiment

Would you like to make a ghost egg just in time for Halloween? Here is an easy way to do just that and teach your child about science at the same time! It is definitely a favourite at our CEFA Early Learning schools – give it a try at home. It will mesmerize your child – I guarantee it!

Best Ages for This Activity

Two to five

How to Make It

Ingredients

  • An egg (you can make more if you want)
  • A glass or glass jar
  • 1 can of tonic water
  • 1 cup white vinegar
  • A black light – I know that this is a little bit of an investment at $34, but a black light is fascinating to children, offers hours of play and can be used for many, many other activities I have on this site (just look up glow-in-the-dark). Plus, you can always use it yourself afterwards if you are in the mood for a throwback party with your spouse. You already have tonic water and the light – all you need is a little gin.
  • Some white paper and a pencil, or a notepad and a pencil, for your child to draw their observations

Let’s get Started!

  • Invite your child to try a science experiment using an egg and a magic potion that they can prepare to transform into a “ghost egg”
  • Gather the ingredients
  • In a cup or glass jar, mix in equal parts (for example, ½ cup and ½ cup) the tonic water and white vinegar. You will need enough to fully submerge the egg. If you have more than one egg, you can put them all in the same jar, but make sure there is enough liquid in it. This is your magic potion. To prove it, you can turn the lights off and shine the black light to it to see it beautifully glow in the dark.
  • Invite your child to very carefully place an uncooked egg in your magic potion and watch with amazement as it gets enveloped in beautiful bubbles (turn on the black light for this)

  • Over the next few days, something very special will happen, so encourage your child to visit their experiment often and journal their observations, noting any changes. If they are young, they can draw what they see in their notebook. If they are a little older, they can write about it too!
  • Ask your child to predict what will happen and encourage them to write or draw their hypothesis in their notebook.
  • After 7 days, you will be able to remove your egg from the jar and… ta-da! You now have a ghost egg! Much to your child’s amazement, you will discover that your ghost egg has no shell and is bouncy and completely translucent. As if that was not enough, your ghost egg also glows in the dark!
  • You can compare your ghost egg with a new fresh egg, to show your child where they started and where they are now.
  • Was it the magic potion? How did the egg become a ghost? What happened to it?

The Science Behind This Experiment

The acid in the vinegar completely dissolves the shell of the egg, leaving only its membrane intact.

Here is the chemical reaction that takes place:

The bubbles you saw forming on the shell are carbon dioxide (CO2). Vinegar is an acid called acetic acid (CH3COOH). Eggshells are made of calcium carbonate (CaCO3). The acetic acid in the vinegar reacts with the calcium carbonate in the eggshell to make calcium acetate plus water and carbon dioxide that you see as bubbles on the surface of the shell.

The egg also became a little bigger after soaking it in the magic potion. That is because some of the water in the vinegar solution (white vinegar is 96% water) traveled through the egg’s membrane to equalize the concentration of water on both sides of the membrane. This flow of water through a semipermeable membrane is called osmosis.

Learning Opportunities

Children will learn S.T.E.M., particularly math and science. By drawing their observations, they will not only be recording their findings (part of the scientific method) but also sharpening their drawing skills, which in turn helps their writing and penmanship skills.

Make sure you follow the scientific method:

This experiment is so easy to do and enjoyable to even the youngest scientists! We often do it at our CEFA Early Learning schools with our one year old students. All you need is a bag of skittles, a plate and a scientist in the making!

Best Ages for This Activity

One to five

How to Make It

Ingredients

  • A bag of skittles
  • A white plate
  • ½ cup pf hot water

Let’s Get Started

  • Invite your child to try a science experiment using skittles
  • Explain that as a first step, you will place the skittles around the rim of the place. It is important that you encourage your child to do this so that they practice their fine motor skills. You can also encourage them to place them in a pattern (a yellow one, a green one, an orange one, a purple one, etc.), which will work on their math You don’t have to use all the colours, just the ones your child wants to try. What colours go where, or even how many colours you use does not matter. Just keep in mind that it would work better if you alternated colours, just like on the picture shown.
  • Encourage your child to form a circle around the plate:

  • Once the skittles are around the plate, ask your child: what do you think will happen if we add hot water to the centre of our plate? Encourage your child to write down or draw their predictions (hypotheses)
  • Test: invite your child to pour hot water in the centre of the plate. You will need just enough water so that the skittles are all touching water, but not submerged. You can also start a timer to see how long the reaction takes (math) and take photos. The most important aspect is to observe and describe what is happening.
  • Your child will notice that as the candy shells dissolve in hot water, they create a beautiful rainbow effect! Observe what shape it takes.
  • Invite them to draw what happened (writing).
  • Don’t forget to use the steps of the scientific method:

  • Questions you can ask:
    • What do you think happened to form the colours in the water?
    • How long did it take for the colours to form a rainbow?
    • What do you think would happen if we tried with less skittles? Or two rows of skittles? Or two colours only? Or three?
    • Do you think the candy will taste different after it makes a rainbow?
    • In what way?
  • Do you know why the colours don’t mix as they dissolve? Each colour of candy coating has a different sugar density, which is why they stay separated.

Learning Opportunities

This is a fun S.T.E.M. activity where your child can see a chemical reaction as it happens. It has so many opportunities to learn math especially: You can learn colours, you can count, you can make pairs, or patterns, you can measure how long it takes for the rainbow to form (measuring time) and even compare two plates side by side using cold water, warm water and hot water. All the while, use the scientific method to predict what will happen, test and record your results.

Make sure you use as much math vocabulary as you can (for example, measure time, measure the intensity of the colour as it dissolves, etc. Use descriptive words like long/longer/longest, fast, intense, etc.) and use as many opportunities as you can to measure, sequence, count and compare.

CEFA tip: Remember to let your child do as much of the process as they are capable of (you will have to help with the hot water, though).

Growing Gummy Bears

This fun and super easy science experiment teaches your children about osmosis. Plus, what’s more fun to experiment with than yummy gummy bears? And yes, in the name of science, everyone should taste the gummy bears! Our students at CEFA Early Learning schools love it – give it a try at home.

Best Ages for This Activity

Two to five

How to Make It

Ingredients

  • 8 gummy bears
  • 2 small bowls
  • ¼ cup of salt
  • 1 cup of water

Let’s Get Started

  • Invite your child to try a science experiment
  • You will see what happens when you put a gummy bear in salt water and compare with gummy bears left out of the water
  • Boil ½ cup of water (be careful with your little ones around boiling water)
  • Add salt to the water, mixing it until no more salt can dissolve in the water.
  • Let the salty water cool in the fridge (if the water is not cooled, it will melt your gummy bear).
  • Once your water is cold, you can pour it in one of the bowls (plain white bowls are best so children can see the process)
  • In the other bowl, add plain tap water, unsalted
  • Make sure both bowls have the same amount of water and enough to cover the gummy bears J
  • Invite your child to place 2 gummy bears in the salty water bowl, 2 in the tap water bowl and 2 will be left out of water, to compare. The other two are for you and your child to enjoy.
  • Start the experiment in the evening or late afternoon and then leave it overnight.
  • Ask your child to predict what will happen to each of the gummy bears (do you think they will shrink? Grow? Stay the same? Disintegrate? – this can happen if you leave them in the water too long)
  • The next morning, see what happened. You will find that compared to the control gummy (the one left out of the water bowls, untouched), the gummy in the salt water grew quite a bit and the one in plain water grew even more. This is a delightful discovery for the children.
  • I encourage you to measure them, draw them and record your discovery whichever way your child can.
  • Of course, your child will want to try eating the gummies, which is an amazing sensory activity. Compare how they taste and how they feel in your child’s mouth. Encourage your child to use vocabulary to describe the texture and taste. Also describe how they feel to the touch before you try tasting them.
  • Don’t forget to use the steps of the scientific method:

  • Questions you can ask:
    • What do you think will happen to the gummy bear that we placed in the salty water bowl? Why?
    • What do you think will happen to the gummy bear that we placed in the salty water bowl? Why?
    • How long do you think we should leave the gummy bears in the water for? (use a timer if you can)
    • Do you think the gummy bears will taste different once they are soaked in the water for that amount of time? Do you think they will feel different? In what way?

Once you have posed, answered and tested all of your questions, you can explain what actually happened to your child.

Here is what happens in this experiment: What you witnessed in this experiment is the process of osmosis. Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.

Gummy bears are made of sugar, flavour gelatin and warm water all mixed together to form a “gummy bear solution”.  Once. The solution cools, some of the water dissipates from the solution and the gummy bears become firm but still chewy, thanks to some of the water still remaining in the gelatin. That little bit of water remaining in the gummy bear acts as a solution of water (with a lot of sugar dissolved in it).

When you place the gummy bear in tap water (which does not contain sugar in its solution), the different solutions of water will try to balance each-other. The plain water, with very little dissolved in it, will move towards the solution of water with a lot of sugar dissolved in it – the gummy bear. This movement of solvent from one of low concentration to one of higher concentration is called osmosis:

In contrast, when the gummy bear (solution with a lot of sugar) was placed in the salt water (solution with a lot of salt), it tried to equalize as well, but since the gummy bear had more sugar in the water than salt in our salty water, not as much water moved into the gummy bear to balance the solution. This explain why it grew but not as much. It still means, however, that the salt water had less salt in it than the gummy bear had sugar (imagine how much sugar is in that tiny gummy bear).

Learning Opportunities

This is a fun S.T.E.M. activity where your child can see a chemical reaction as it happens, as well as compare to the original (the control gummy bear) after the fact, to see the changes that took place. For better science learning, follow the steps of your scientific method with your child. Make sure you use as much math vocabulary as you can (for example, measure time, measure the gummy bears themselves, etc. Use descriptive words like big/bigger, small, medium large, more/less dense, etc.) and use as many opportunities as you can to measure, count and compare.

CEFA tip: Remember to let your child do as much of the process as they are capable of (you will have to help with the boiling water, though).

Hammering Pumpkins – Fine Motor and Hand-Eye Coordination Activity

Fine motor skills and hand-eye coordination are very important skills to acquire in the early years. During pumpkin season, set up this fun but challenging activity that is sure to entertain your child for hours! All you need is a pumpkin, a few golf tees (or real nails if you dare and a wooden hammer).

It is definitely a must in our writing curriculum at our CEFA Early Learning schools!

Best Ages for This Activity

One to five

How to Make It

Ingredients

  • A pumpkin (choose a steady one so it is easier for your child to hammer without having to steady it).
  • A few golf tees
  • A hammer that is safe for children. If your child is older and you can safely supervise, your hammer can be a bit more sturdy, like this one or this one.

Let’s Get Started!

  • Invite your child to hammer tees into the pumpkin
  • Demonstrate how to use a hammer, especially how to protect their fingers.
  • While you supervise, your child can hammer as many holes as there are tees into the pumpkin. This will allow them to practice much needed fine motor skills, as well as develop their hand-eye coordination skills.

Learning Opportunities

Children will learn life skills by learning how to hammer. They will also acquire essential fine motor skills, needed for writing. They will also learn vocabulary by describing what they are doing and the amount of resistance the pumpkin offers. They can learn S.T.E.M., especially math, by comparing how much force they need to apply on a small pumpkin versus a large pumpkin. They will learn engineering my trying to steady the pumpkins as they work. They can also compare different hammers if you offer them, and what types of hammers are more effective for the job. It is a wonderful sensory activity as well!

Extended Learning Opportunities

  • Use the pumpkin with its new holes to make a beautiful night light. All you need to do is hollow the pumpkin, add a candle inside and watch it glow through the holes.

Glow in the Dark Magic Potion

When I was little, I dreamed of making magic potions and colourful experiments! My boys were the same (I still catch them today making some of the recipes and activities on my website). If your child is a budding scientist, try this super simple experiment at home. It glows in the dark and the potion foams into beautiful colours! It is a favourite at our CEFA Early Learning schools.

Best Ages for This Activity

Two to five

How to Make It

Ingredients

  • ¾ cups of baking soda per colour that you would like to try
  • White vinegar
  • Glow in the dark paint (or you can try this less expensive alternative, which you can use on your skin for Halloween as well).
  • Transparent cups (drinking glasses are fine, or plastic cups) – 1 per colour you want to try. We did 8 different colours
  • A black light
  • A measuring cup (if you do not have one, use a spoon and count the equivalent of ¾ cups)
  • Squirt bottles (optional – read below)

Let’s Get Started!

  • Choose a small, dark room that can easily be wiped down (I like using the bathtub for experiments like this, as it is so easy to clean up). Make sure you can easily close the door and turn off the lights and plug in the black light ahead of time.
  • Alternatively, you can do the experiment outside when it is dark
  • Turn on the black light
  • Invite your child to try a science experiment – making glow in the dark potions!
  • Introduce the materials to your child: the paint, the black light, the cups, etc.
  • Invite your child to pour ¾ cups of baking soda into each glass container (using the measuring cup for added math learning)
  • Invite your child to add three dots of glow in the dark paint to each cup containing baking soda (no need to mix)
  • Use as many steps from the scientific method as possible. For example:
    • What do you think will happen if we pour the vinegar onto our baking soda?
    • (Inviting them to form a hypothesis) Will it dissolve? Will the colour stay in the middle of the powder as it is now? Will it make colourful foam? Let’s see! (now test your hypothesis by pouring the liquid into the cup)
    • What happened? That was amazing! (share the results)

  • You can use anything to pour the vinegar (a little at a time) into the cup of baking soda, but I like to use a squirt bottle, which I use over and over again for many of my activities, so it is a good investment! They are very inexpensive and can even be found at the dollar store. Then you can experiment with squirting a little or a lot of vinegar at one time.
  • You can keep going until you run out of vinegar and baking soda (or you can always add more)
  • I encourage you to invite your child to touch and feel the “potion” as it is erupting out of the glass - it is non-toxic.
  • Have lots of fun playing with this!

Learning Opportunities

This is a fun activity more than anything. It is a great opportunity for your child to practice observation skills and to manipulate the outcome by varying the ingredients. It teaches your child science in the process and math as it has so many opportunities to measure and compare.  You have an art component if you choose to do the extended learning as well. Make sure you use as much math vocabulary as you can (for example, measure, count, vary intensity, name the colours, etc. Use descriptive words like slower/faster; more/less; a lot/a few; etc. and use as many opportunities as you can to measure, count and compare.

Extended Learning Opportunities

  • Try with the black light on, then off and talk about what they notice both times
  • Try with more paint and then less (you can talk about the intensity of the colours)
  • Try adding a little dish soap to your squirt bottle (it will slow down the reaction). If you have two squirt bottles, add it to just one of them so you can compare how fast and slow they foam.
  • Try on a shallow glass bowl or plate where you can disperse the baking soda at the bottom (about 1 cm high) and then add various colours of the paint in little dots, but on the same plate. When you pour the vinegar on top, you will see it foam in lots of different colours for an amazing effect. Bonus: see how the colours mix and what colour you have left at the end. You can then talk about colour mixing.
  • Try placing a large piece of absorbent white paper under your cups before adding the vinegar. Let it dry and see your art piece at the end of your experiment. Try placing the paper on top of the cup (above the foaming bubbles) to see “bubbles” printed on your paper. You can also use paper towel instead.
  • Try adding the paint to the vinegar instead of to the baking soda (add vinegar and paint to your squirt bottles) – the colours will be more even and also brighter and more intense.

CEFA tip: Remember to let your child do as much of the process as they are capable of. Ask questions and use math and descriptive vocabulary for added learning (for example, instead of saying “this one is foaming so much” you can say “look at the yellow potion! It is foaming more than the red one We must have added more paint to it!)
