Explore the wonders of winter with at-home fun

Frosted window panes; a sky full of delicate snowflakes; a flurry of activity beneath the ice, amongst the trees and all around us … winter truly is a wonderland! There is so much to learn throughout the colder months, from the science of snowflakes to the hibernation habits of different creatures and beyond.

Turn your kitchen into a laboratory as you grow crystal snowflakes, make fireworks in a jar and mix up a batch of holiday-inspired play dough. Suit up in your warmest gear and explore biodiversity in your own backyard, then head in for some warm, freshly baked cookies complete with animal footprints. And of course, don’t forget to spend some snowy days sharing science with your whole household with science-themed games.

Check out our calendar for an overview of what’s to come. There are endless winter wonders to uncover!
