It’s back-to-school time, but that doesn’t mean you can’t extend summer a little longer with STEM water activities.

September and October are great months to get a little wet in STEM classrooms (or outside!) because it’s still pretty warm outside. Get students excited to get back to learning with these engaging and educational STEM water activities!

1. Foil Boat Challenge

STEM water activitiesWho doesn’t love this classic STEM water activity? Have students separate into groups, and each team gets four pieces of 4″ x 4″ aluminum foil. Their goal is to build a boat out of the material with no adhesive. The boats will be placed in a basin of water, where pennies will be placed on them until they can’t hold any more. The team whose boat can hold the most coins before sinking wins!

This project leads to conversations about buoyancy, surface tension, surface area, and more and can be tweaked to fit the appropriate grade level.
