Summer will be here before you know it, which means you’ll have little ones running around the house without a lot of ideas for keeping them entertained. We like to do some summer STEM activities with the kids during the summer months to help keep them engaged and learn while they’re off school.
Here are the best summer STEM activities for elementary students to do during the summer.

Whether you’re a homeschool mom or a mom with kids in public school, STEM activities are the perfect way to keep learning during the summer! Even your little ones can get involved in the STEM fun!
