Introductory activity: Using a globe, battery and switch
How can a globe, battery and switch be connected so you can make the globe light up when the switch is pressed?
What to use
Globe, battery, switch, wires.
What to do
Find a way to join the globe, battery and switch that will make the globe light up.
Draw a picture of how you did this.
Refer to this diagram of an electric circuit in which the lamp lights up:
Would it matter if the positions of the switch and the battery were swapped in the circuit?
What would happen if the lamp holder was connected the other way around?
What would happen if the light globe was unscrewed a little while the switch is being pressed?
What would happen if the battery is placed in the circuit the other way around?
Try each of these to check your answers. Try to explain what happened.
