National Standards for Grades 3-5
 
Students use the Engineering Design Process to problem solve as they build electromagnets. Inquiry based investigations explore core materials, core thickness, number of wraps per coil, magnetic field, electrical charge, and heat energy. Investigations culminate in a design the strongest electromagnet competition. Includes an extensive instructor’s manual with lesson plans, background information, reproducible stepwise student instructions, worksheets, complete answer keys, and all materials required for investigation. Allow four thirty minute lab times for conducting experiments. Batteries included. Goggles required.
