They experiment with making their parachute out of different materials, shapes and sizes to see which makes the best one. They learn what it means to do a fair test, and think about how to compare the strengths – and failings – of one parachute compared to another. br br ExpeRimental, brought to you by the Royal Institution of Great Britain, is a series of free short films that make it fun, easy and cheap to do science at home with children aged 4 to 10.
