During our science work on forces we have conducted experiments on air resistance and friction. Chief scientists (the ones in white lab coats) helped us carry out fair tests and only changing one variable and keeping all the other elements of the investigation the same. We discovered that the larger the parachute, the more surface area could create more air resistance. We also discovered that the more course or rubbery the material, the more friction was created and slowed objects down. It was great fun finding these things out!
