		+	: Time how long it takes a single Cupcake case to fall from the ground from 1.5 metres high.
		+	: Repeat this for two, three, four and five cupcake cases stacked together.
		+	: This changes the weight without changing the shape of the object.

		+	'''Air Resistance and Size'''
		+	: Cut several different size parachutes from bin liners.
		+	: Ensure that the surface area of each parachute increases by the same amount each time. This can support math skills calculating area of shapes.
