Third Grade: Forces and Simple Machines

Grade 3 students have been studying forces, simple and compound machines, and magnets. They will use all of this knowledge when they build a compound machine using VEX kits to solve the real-world problem of rescuing a (plastic toy) tiger who fell in the moat at a zoo!
