Can be used as a stimulus for considering how to conduct a fair and effective investigation in any scientific topic. Specifically as part of a topic on friction, the children could watch the clip and then be set the challenge to design and make a parachute that would help Rapunzel escape from the tower. They could be asked to investigate how to make the best parachute by changing only one variable, for example weight, material, length of strings, size of canopy, shape of canopy and so on. The children can then present their findings. Alternatively, they could use their knowledge from this clip and further research and investigate this to design a poster which explains about friction including the pros and cons for an alien from another planet.
