Children from Links Primary School in London investigate harnessing air resistance in order to safely drop an egg, experimenting with different parachute designs.

Large surface area = more air resistance. For example, when a parachutist opens their parachute, the surface area increases. This produces a large amount of air resistance.

However, the air in the atmosphere can change the speed of a fall, and parachutes rely on this to work. Air resistance is a type of friction, or the resistance of motion when objects rub together. You ...
