43 Easy Winter STEM Activities


How do animals stay warm in the winter? What happens when snow melts? What is frost and how is it made? These are just a few of the questions I have been asked when teaching young children when the winter season starts. This collection of winter STEM activities are a great way to teach, and show children the answers to their questions as they explore the world around them.

If you have never done a STEM activity before, STEM activities involve learning focused on Science, Technology, Engineering and Math. The more of these subject areas combined together into an activity the better.

The benefits of STEM activities and STEM challenges for kids are endless. I have watched children develop critical skills such as, problem solving, understanding how things work, teamwork and resilience through STEM activities.

STEM activities often use simple, every day materials and often don’t require much prep work. They are ideal for classroom learning, or they can easily be done at home.

The collection of Winter STEM Activities below include a variety of learning activities, all with a winter theme. I hope that you find some ideas to bring to your children, or students, as you look through the collection of activities, beginning with science.
