Young students learn about electric current by building 30 circuits that light up a bulb, create on-off switches, spin a motor, and more. They also explore magnetic fields by discovering which metals are magnetic and how a compass works. Finally, experimenters make a connection on how closely related the two properties are by combining their new learnings to construct a loudspeaker, relay switch, and a Morse code telegraph key! Bright colors and snap-together pieces are friendly and easy to use. Kit includes 64 pieces and a 64-page manual. Kit requires 2 AA batteries (not included). See manual for full contents list. Recommended for Elementary and up.
