5. Build a Junk Boat
This engineering activity on our list of quick and easy STEM activities for elementary school students is very fun and children will love it. You can make junk boats using duct tape and some cans or cloth or many other materials you can find. Fill a small pool for children with water and test your boats. Children can blow the boats across the water using straws. After testing the boats, you can make adjustments to make the boats go faster.
