Gravity resources

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.

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.
