Which parachute will float the longest???
We had to design a fair test to see which of our 3 parachutes would float the longest.
Some of us made 3 parachutes out of the same material (mainly plastic bags) but made them different sizes.
Others of us made 3 parachutes the same size but out of different materials.
We had great fun testing our parachutes from a great height in the playground.
