Activity: As a class work through the background information to forces in the presentation. Use this information to check your learning from last lesson and make any necessary changes.

Activity: in pairs/threes cork around each of the investigation stations, carefully exploring the equipment to learn about forces. Complete the activity sheet for each station.

Ensure that the equipment is ready to be used by the next group when you are finished with it.
