Embrace The Cold With Winter Science Experiments

Winter brings about it’s own special kinds of challenges. My butter is rock hard. Feet always cold. And it takes ages to get everyone into their gear and out the door. But it is also pretty. After a snow fall the world literally sparkles. It’s like fairies have come through and sprinkled the world with their magic dust. It can also inspire some amazing science experiments and labs with some fantastic learning opportunities. When nature is your natural freezer, might as well make ice. And winter science!

I’m not a big fan of winter. Which kind of stinks, because we live in a place where it often snows in September and we still have snow in May! In fact, during my lifetime we have had snow every single month of the year. The year it snowed in August I was working in an ice cream shop. Needless to say it was a very quiet day for this ice cream scooper.

Now since this is home, and winter is a big part of life here, I need to embrace the cold. Welcome the snow. Find ways to bring out the best of this weather.

So I’ve stuffed myself into my parka and my winters, and trudged out into the wilds to bring you this list of winter science experiments that celebrate the cold and bring some fun to those chilly days!

However, since I know I’m not the only one who hates outdoors, plus not all of you live where nature is a freezer, I’ve divided these activities into two categories: indoor winter science and outdoor winter science. Enjoy!


Engineer an Ice Lantern – When the world is a freezer you might as well make ice. And pretty ice with this ice lantern engineering activity or make some outdoor ice ornaments with this tutorial.

Ice Sculptures – Continuing with how easy it is to make ice at this time of year, why not challenge kids to build ice sculptures. Figuring out how to keep those slippery blocks of ice together involves some scientific problem solving!

An Ice STEM Engineering Challenge that is fascinating and an inspiring learning opportunity. Perfect for homeschoolers and young scientists, with everything you need in one box.

Melting Magic – Snow and Ice Science – This is a great project to do with kids as it demonstrates a principle that many need to see to believe.

Snow Ice Simple Science is an experiment all ages can do and teaches valuable lessons about the molecular structure of water in ice form versus snowflake.

Frozen Bubbles – Ready to uncover all the secrets? I know, you have tried to make frozen bubbles and it has failed every time, right? I know, I’ve been there! After lots of trial, error and research into the science behind frozen bubbles we share all of our secrets to ensure your success in making the most stunning frozen bubbles!

Make Snow by exploring the Mpemba Effect – This is the most spectacular experiment we do each year, but it will only work under very rare and special conditions… crazy, insane cold!

How to Make Snow and explore a cool property of water called the Mpemba Effect. It uses a little bit of science, a little bit of hot water, and a whole lot of cold to make this spectacular snow storm happen like magic.

Sledding is a popular winter outdoor activity and a great opportunity to see physics at work in real life! Here are some ways you can chat about physics next time you are on the hill. Still want more physics? Don’t miss our exploration of Newton’s Laws.

Crush a Bottle… with your mind! – This is one of our favourite winter science experiments. The older kids love doing it and wowing the little ones.

Bottle Crush - Crush a bottle with your mind, and a little science. Inspired by Mythbusters, a science experiment that seems like magic!


Winter STEM Study – Salt is a big part of life in winter. It is everywhere trying to combat the ice that threatens to make us fall or send our cars sliding. Study the effects of salt on ice in this study.

A fascinating Winter STEM Activity for elementary kids exploring the effect of salt on ice. Significant results provide rewarding STEM hands-on learning.

Create a Frosted Wreath – The results of this experiment are so pretty. They sparkle just like the frost outside as tiny crystals form on the delicate strands of the wreath. For a different twist on this crystal making experiment, try making a snowflake version or practice making jumbo sized crystals or even making them scented (imagine a pine or peppermint scented design).

Who doesn’t love a little hot chocolate science on a cold winter day? With hot chocolate comes marshmallows, try your hand at a marshmallow science experiment or make some extra festive marshmallows for those holiday hot chocolates.

Heat is a big topic of conversion at this time of year, so why not tackle some heat transfer experiments to better understand how heat moves between objects.

These Heat Transfer Projects For Kids provide lots of hands-on STEM activities to promote understanding of the laws of thermodynamics.

What do we love during the cold winter? Nice warm baths! And with that we have really loved learning how to make bath bombs. It is a fantastic STEAM project for your tweens and teens and fosters so much creativity and understanding of chemistry.

Explore friction with this experiment exploring how things slide on ice. Although this experiment shows an indoor version I think it would be even more fun to head outside and test it.

Snowflake light reflections are a beautiful and fun way to play on a sunny winter day.

This Winter Scent Lab is a great way to spend a cold afternoon inside where it is warm. Kids will love making the scent bottles and learning how their sense of smell works.
