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 on page 5 of the PDF, learners use their knowledge of energy and batteries to create homemade flashlights.

This activity introduces learners to the structure and properties of carbon nanotubes.
