Year 5 carried out two investigations to find out about air resistance. First of all, they walked and ran in pairs holding a large piece of paper to see what air resistance felt like. They discovered that when they ran they could feel the force of the air more. Secondly, they dropped a flat piece of paper and scrunched up piece ( both the same size) to see which piece would reach the ground 1st. They found out that the flat sheet took the longest because it had a greater surface area therefore there was more air resistance to slow it down.
