3rd class investigated the best materials to create a parachute in March 2019. In the first part of this activity, they learned about gravity. They investigated how paper falls using a scrunched up piece of paper and a flat piece of paper dropped from the same height.
They learned that the reason the flat sheet is slower to fall is because it has more air resistance. This was the basis for their parachute. They chose three materials to test - aluminium foil, kitchen paper and baking paper. In order to keep the test fair, they use the same size material for each parachute and the LEGO men that the parachutes were tied onto were carefully weighed to ensure they were all the same! Before they carried out the experiment, they predicted which material they thought would make the best parachute...her's how it went!
