Hands-on Activity

Electro-Lights

Fun Forces
Summary
In this activity, students build simple circuits to investigate the conductivity of solutions. They build and test a simple circuit using a bulb, battery, and wire. Next, they interrupt the circuit by running the wires through containers of liquids to explore which solutions will conduct enough electricity to light the bulb.
Overview
Topic: Conductivity
Real World Science Topics:
