New Standards for Grades 5-8
 
Designing simple electric motors from wire and magnets, students explore the effects of number of coils, wire thickness, and sizes, shapes, strengths, and types of magnets. They are guided through the engineering design process with four progressive experiments and a design competition. Great for introducing guided inquiry-based learning, systematic problem solving, and engineering design practices. Kits include instructor’s manual with lesson plans, background information, reproducible stepwise student protocols, and guided worksheets. Allow four thirty minute lab times for experiments, and 20 minutes for competition. Safety goggles and batteries not included; single kit (15- 210) requires 3 D-cell batteries; class-pack (15-212) requires 18 D-cell batteries. Designed for working in groups of four.
