Looking for winter science experiments for preschoolers? These science projects are perfect for preschool kids! One of my favorite things to do with my kids are STEM activities and science experiments. We love giving our science experiments a seasonal twist, which is why we have so many winter science experiments here on STEAMsational.
Aside from writing, science is my second-favorite subject to teach. We didn’t do many science experiments growing up, so I love the chance to do more hands-on science with my kids.
Here are easy winter science activities for preschool that will be the talk of your classroom.
