Four seasons of science experiments are perfect for preschool, kindergarten, elementary school, and beyond! Keep your kiddos busy all year exploring the ever-changing world around them!
Winter Science Activities
What happens in winter? Well, it gets pretty cold in some places, and it snows! Although some of our experiments use real snow as a supply, many of our winter science activities do not! You can quickly try three of our favorites, including frost on a can, polar bear blubber, and ice fishing, even if it’s 100 degrees outside!

Summer Science Activities
School’s out, but that doesn’t mean that you have to wrap up science lessons for the year too. Our science is always so playful that kids want to dive in and learn more. Don’t stop just because of the season.
Summer is the perfect time to get outside and explore science on the go, too! We’ve created 12+ Camp Weeks to get you right through the summer. A bottle rocket or DIY solar oven is the perfect summer STEM project.

Science Experiments By Age Group
We’ve put together a few separate resources for different age groups, but remember that many experiments will cross over and can be re-tried at several different age levels. Younger kiddos can enjoy the simplicity and hands-on fun. At the same time, you can talk back and forth about what is happening.
As kiddos get older, they can bring more complexity to the experiments, including using the scientific method, developing hypotheses, exploring variables, creating different tests, and writing conclusions from analyzing data.
