Falling Cake Cups

Produced by Nelson Thornes, this resource helps students look at aspects of how science works. Students are asked to analyse a set of given results, and draw a graph. The activity is based around two friends observing a paper cake cup fall to the floor.

Iqbal and Molly decide to carry out an investigation to test their hypotheses about falling paper cake cups. Molly thinks smaller ones fall faster because they have less air resistance but Iqbal disagrees. He thinks larger ones fall faster because they are heavier and will have more gravitational potential energy.

HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
