...with making and testing parachutes!
We have started a project on the solar system. We talked about gravity. We learned that gravity is a force that pulls us down towards the centre of the Earth. We dropped a pencil and a book from the same height at the same time. They reached the ground at the same time. Gravity will always pull just as hard on any object, no matter how big or heavy it might be.
But then how do birds fly? We dropped two pieces of paper to the ground from the same height at the same time. One was scrunched up in a ball and the other was flat. The flat piece seemed to float down to the ground and took longer to get there. We decided that this was to do with the air catching in it, like birds’ wings or a parachute.
We made our own parachutes using a tissue, 4 pieces of thread, a piece of Lego and some sellotape. The air caught in the parachute and brought the Lego safely down to the ground!
