Winter Sensory STEM Experiments

These winter sensory STEM experiments are perfect if the cold never bothered you anyway!

From ice cream to ice chalk, celebrate the winter solstice with some (literally) cool sensory STEM experiments. Join us as we explore the chemistry behind some ice-citing concoctions, learn a trick to make your friends think you can freeze time, and more! 

A frozen twist on a classic favorite, ice chalk is a fun way to take your sidewalk art game to the next level! 

Sidewalk chalk is cool but ice chalk is even cooler, literally! Start in the kitchen concocting your chalk paint-sicles, then, when they're ready, head outside and get to painting your pavement!


I scream, you scream, we all scream "SCIENCE" with this ice cream science project!

Feel the chill this winter as you learn the science of cold by making homemade ice cream! This vanilla or chocolate ice cream science project doesn’t require any fancy equipment, just plastic food storage bags, elbow grease, and chemistry!

What if we told you that you could freeze time with just a balloon, tape, and some water? 

We promise this isn’t CGI magic or a trick of the camera. What you are seeing is a particularly interesting fluid dynamic, which is a scientific way of saying the flow of a fluid (which is any liquid or gas), called laminar flow.

If it doesn't feel like winter, it can still sound like winter

When you think of winter, you probably think of cold temperatures, icicles, and snow. But many places around the world enjoy a tropical December - February. If you can't walk in a winter wonderland, you can at least make it sound like you are with this Foley art activity!
