Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.

In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.

In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

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, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

In this technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.

In this technology activity, learners build simple circuits, design soft circuits using conductive thread, and then sew switch-activated circuits.

In this activity, learners explore the concept of conducting or insulating electricity.

In this activity, learners explore the properties of metals at four stations. The stations include A) Magnetism and Breakfast Cereal; B) Conductivity of Metals; C) Alloys; and D) Metal Plating.

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.

In this activity on page 4 of the PDF, explore the unique molecular structure and conductive nature of graphene. Learners construct a circuit with a battery and LED bulb.

This lesson focuses on graphene and its electrical properties and applications.
