Unit 4F: Conductors and Insulators

Conductors and Insulators

What materials are good conductors of electricity?

How can we test various materials to see if they are conductors?

What do the results show?

Are there any exceptions to the general rule?

Unit 4F: Changing circuits

Changing circuits

How can you change the brightness of the bulb?

List all the things you could change to do this.

What will happen if you add more bulbs to the circuit?

What would a switch do to the circuit?

If the bulb was exchanged for a motor, how could the speed of the motor be changed?

How could the loudness of a buzzer be changed?

?
