As part of Year 5’s learning about forces and air resistance, we are designing a fair test to find out what makes the best parachute. First, we learnt about how gravity and air resistance interact and used this to form scientific questions. Then we drew on our knowledge about gravity, mass and surface areas to help us make hypotheses about which parachute would work best. We worked in groups to carry out our scientific method, thinking carefully about constants and variables. Now we are ready to test and make observations about the parachutes that we made.
