Snowball fights are loads of fun, but the weather doesn’t always want to cooperate. Bring the fun indoors, and add a STEM angle to things with this DIY snowball catapult activity.

For an indoor STEM option that still has all the winter vibes, try this giant crystal snowflake experiment. The printable template helps keep a nice, clean snowflake shape.

Frozen ice bubbles seem like pure magic, but they are actually a great way to teach kids about science. Watching crystals form in real time is an amazing, one-of-a-kind experience.

Let kids experience the magic of carving their own path through a snowy wonderland. Set up a marked trail with things for them to discover, or let them go their own way for loads of snowy outdoor fun.

This winter STEM activity is great because it doesn’t even require snow, just freezing temps. Kids prepare their colored ice blocks, then play the day away once they are ready.

A snow volcano might sound like an oxymoron, but it’s actually loads of fun. Kids build a volcano base in the snow, before adults work a little chemical magic to help make it erupt.

Polar bears fascinate kids because these enormous, snowy creatures spark curiosity like no other. Let kids explore how polar bears stay warm by simulating their blubber layer and discovering how it helps them survive in icy habitats.

This winter STEM activity is tons of explosive fun for kids and adults. With a little setup ahead of time, this baking soda and vinegar experiment will end with a bang!

Here’s another fun way to teach kids about cold temperatures and a little basic chemistry. Challenge them to catch an ice cube fish using nothing more than a piece of string and some salt.

A melting snow experiment is so easy to set up, and even leaves room for a fun little craft project as well. Kids can learn about thermodynamics with nothing more than a ruler and a jar.
