Terminal Velocity Level Assessed Task

Based on the popular level assessed tasks published by Badger. Pupils work towards their target grade using the assessment criteria. This task focuses on the terminal velocity of a ball bearing and the forces acting at different times.
Start by showing the class a ball bearing falling through a cylinder/tube or washing up liquid/oil. Pupils then explain why the ball bearing reached terminal velocity using force diagrams (they can use calculations to determine the weight of the ball). They are also asked to draw a velocity-time graph. Assessment criteria included for peer/self assessment.
