Even here in Florida Winter can make us want to stay indoors (granted, its much better than Montana!), and if your household is anything like mine, our little ones are itching for some hands-on fun. 

Just because we aren’t bundled up in layers doesn’t mean we can’t embrace the season with all its charm. As the days get shorter, I’ve compiled a list of my favorite winter STEM activities perfect for our inquisitive preschoolers. 

So, grab a cup of cocoa, and let’s dive into these frosty fun winter themed adventures that’ll keep those tiny hands and curious minds both warm and engaged!

What Is STEM?

When we chat about STEM for our tiny tots, especially with winter activities in the mix, we’re talking about blending Science, Technology, Engineering, and Math in a kid-friendly way.

STEM education for preschoolers is an innovative way to help young minds learn different concepts about the world around them through hands-on learning. This is done by engaging young learners through easy STEM activities for preschoolers and projects that cover multiple disciplines within the STEM framework, and this comprehensive approach to learning helps preschoolers retain and engage with material in an improved fashion. 

It’s all about nurturing their natural curiosity with snowflakes, chilly temperatures, and frosty patterns. Imagine building ‘snow’ structures or exploring the magic behind melting ice. It’s the wintry world, seen through a STEM lens, made fun and simple for our preschoolers!

How I Chose These Winter STEM Activities For Preschoolers

Selecting the best winter STEM activities for our preschoolers was a labor of love. I scoured popular STEM websites, hunting for gems that’d captivate my son’s heart. We then had fun ‘test-driving’ several. I have already reviewed lots of STEAM and STEM projects for kids on the main page, but I wanted to provide a more detailed view of my favorite STEM winter activities for preschoolers here. 

I prioritized ones that were a breeze to set up, promised a good half-hour of engaged play, and offered a wholesome STEM learning experience. Because if my little guy loves it, I’m pretty sure yours will too!
