Using the Explorer-U Electric Wiz Buzzing Adventure Kit

Quick answer

Start with the lemon battery experiment, then build simple circuits to light a bulb, and finish with the buzz wire game to test your steady hand.

Step-by-step instructions

1. Build a lemon battery: Insert the zinc and copper electrodes into a fresh lemon following the I Know Guide. Connect the wires to a small LED or buzzer to see electricity generated from fruit acid. If the LED does not light, try rolling the lemon to release more juice and ensure good contact with the electrodes.
2. Set up a simple circuit: Use the provided wires and bulb holder to connect the battery pack (with 2 AA batteries) to the light bulb. Complete the loop by attaching both ends of the wire to the battery terminals. Make sure the wires are firmly attached to the metal contacts; a loose connection is the most common reason the bulb fails to light.
3. Create an electromagnet: Wrap the insulated wire around a steel nail or rod provided in the kit. Connect the wire ends to the battery pack to magnetize the metal. Test it by picking up small paperclips. Do not leave the electromagnet connected for more than a few seconds—it can overheat the battery.
4. Play the buzz wire game: Form the included flexible wire into a wavy path. Attach the buzzer and battery pack. Guide the loop wand along the wire without touching it. Each touch completes the circuit and makes the buzzer sound. Start with a gentle curve; sharp bends make the game much harder and increase accidental touches.
