Lesson 10:Conductors and

Insulators

The BIG Question:

How can I control the electricity

flowing through a circuit?

a complete path that allows

electricity to flow

closed circuit

an incomplete path that does

not allow electricity to flow

open circuit

opencircuit

closedcircuit

A switch can be used to open and close a

circuit.

The BIG Question:

How do different materials affect

the flow of electricity?

Be sure your batteries are connected from negative to positive!

1. Test each material and write your actual

results on your sheet.

3. Work with your partner to write some

conclusions based on the results of your

experiment. 4. Work on your Electricity Challenge Packet.

2. Return all your supplies to the correct location.
