Summary of activity

Make something that will act as a model earthquake using jelly.

To open the activity

Can I make something to demonstrate what effect an earthquake might have on a building?

The main activity

Make a cocktail and mashmallow structure. Place it on a jelly base.
Program a crumble computer to turn a motor (use 'crumble' software which can be downloaded free)
Stick the motor on the side of the tray and switch crumble on.

Challenge and support

Can you make the motor go on and off, backwards and forwards, faster and slower?

To finish the activity

What happens if you use two motors or make your structure higher?

Learn from me (what worked well for us)

Make sure the jelly is set beforehand.
