14 Winter Science Experiments & STEM Activities

Try a few of these winter science experiments that explore snow, ice and cold temperatures!

As if the past ten months haven’t been historic enough, it seems that we are making history once again with one of the most brutal cold snaps in decades!!  As my grandmother always told me “if life hands you lemons, make lemonade” — so it only seems logical that if life dishes us out a snowstorm (or three!), we should create a few winter experiments along the way 😉

Winter Science Experiments

We’ve got some wonderful winter weather activities for you to try — even if you don’t have tons of snow and ice right now 😉  And not to worry, most of these projects can be done (mostly) inside where it’s warm with only limited outdoor time needed!

If your kids seem to have unlimited questions about winter weather (like “how cold does it need to be to snow?”  or “are there really no two snowflakes alike??”) be sure to cuddle up with a few of these awesome winter science books that will help to expand on the experiments and activities listed below.




The Story of Snow: The Science of Winter’s Wonder — this nonfiction book reads more like a story which is perfect for younger kids.  Illustrations show the process of water varpor becoming snow crystals and the book includes details about how to catch & observe your own snowflakes too!

The Cool Story Behind Snow (Level 3 Nonfiction Reader) – if kids have ever wondered about how snow forms, what happens when a polar vortex hits and how to predict a snow storm, this is the book for them!  With colorful and comical illustrations and a great back-of-the-book set of resources, there’s a ton of winter learning in this book.

Curious About Snow (Smithsonian) — a fabulous book about all things snow!  Kids will enjoy learning about crystalization, the types of snowflakes that form, the science behind snow and more! 

Ok, time to get our winter science on!
