In this design challenge activity, learners design and build a circuit: an "electric highway" that connects a battery and buzzer at least three feet apart using four types of materials.

In this activity, learners build a tiny but powerful flashlight out of simple materials. Use this activity to introduce learners to electrical circuits and conductivity.

In this activity about electricity, learners explore what happens when you blow a fuse.

In this activity about electricity, learners build and test a paper clip switch to turn on a light bulb.

In this design challenge activity, learners invent a device that will make their friends and family ask, "What's buzzing?" Learners design an alarm with an on/off switch that is small enough to hide.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this activity, learners explore the parts of a circuit by modeling, as a group, a “human” circuit.

In this activity, learners build a switch to turn electrical circuits on and off.

In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.

In this activity about electricity, learners identify closed and open circuits. First, learners examine and label diagrams of open and closed circuits.
