Here’s a collection of winter STEM activities that kids will love! These activities center around science, technology, engineering, and math, and all have a fun winter theme.
Whether you are looking for activities to do with a class, an after school program, or at home, I hope you’ll find something that works for you.
I’ve chosen activities that are fun and engaging, but also teach essential science and engineering concepts. These projects also rely on simple materials from around the house – a BIG plus when you are a busy parent or teacher!
Physical Science (Chemistry and Physics)
Physical science has to do with atoms, molecules, matter (including states of matter), force and motion, and more. Static electricity is part of physical science, but I have those experiments listed separately below.
Make a Snowstorm in a Jar. This lava lamp variation is so fun and relaxing to watch! It’s a reaction between citric acid and sodium bicarbonate (a base), so it has nothing to do with snow. But it’s a fun simple chemistry experiment that goes perfectly with the winter season!
We also love these Melting Ice Science Experiments. Explore the volume of ice compared with liquid water once it melts. Then in part 2, kids will experiment to see what substances cause ice to melt more quickly. We compared salt, baking soda, sand, and sugar, and the results were impressive!
Or on the flip side, you can try this Don’t Melt the Ice Experiment. Challenge kids to design a container that will keep ice from melting for the longest amount of time.
How Do Snowshoes Work? This experiment demonstrates how snowshoes (or large paws on an animal) keep you from sinking into the snow. Very simple and effective!
Make some Hot Ice! Again, nothing to do with actual ice, haha. This is fun chemical reaction that creates impressive crystallization and gives off heat. All you need is baking soda and vinegar, and some time.
Math and Design
Young kids will love these Snowball Addition and Subtraction Math Games. Get up and move at math time with these active games!
Grab some toothpicks and marshmallows and design Marshmallow Snowflakes. This is my new favorite. The materials are so simple, and this activity works well for all ages.
Build some Paper Pattern Block Snowflakes! Another one that is beneficial for a wide range of ages. Young kids can work on shapes and fine motor skills, while middle schoolers can design intricate snowflakes and explore angles and lines. The post has a link for printing the pattern blocks.
It’s also a ton of fun to design LEGO Snowflakes. It’s amazing how many different patterns you can build.
These Geoboard Snowflakes are a similar concept with a different medium.
Winter is the PERFECT time to do static electricity experiments because the air is typically much more dry than in the warmer months.
Here are Two Static Electricity Experiments with Balloons that are simple and a lot of fun. These experiments demonstrate the forces of attraction and repulsion created by static electricity.
Make some Jumping Goop! This is a wacky static electricity experiment that you may not have tried before!
You can also use static electricity to bend a stream of water and separate pepper from salt. So cool!
Have fun with Winter STEM Activities!
