First graders are putting everything they've learned about mechanical engineering into action! They know that machines do work for us, that they need an action or force to get it moving, and that another part begins to move!
Using everyday materials, first graders are making sail cars. While the body and wheels of the car remains constant, they are having the opportunity to use what they know about the materials they investigate to make different sails. Testing the sails in front of box fans, they can change their design so that the sail car moves the farthest distance across the carpet with the heaviest weight inside. We'll be testing our sail cars over the next two weeks!
