Gravity resources

Students name the force that delivers water to households from a water tower and then explain advantages and disadvantages of a wind-powered pump compared to a petrol-powered pump.

Three key variables related to high altitude flight are displayed graphically. Students use the information provided to answer a series of questions about flight.

Students carry out and make observations about water in a straw, and suction. Students are then required to explain their observations.

Task: Answer two multiple choice questions. Assessment focus: forces.

Students suggest why two girls of the same weight go down a slide at different speeds, and then identify the forces acting on the girls. The assessment focus is on the forces of gravity and friction.
