Ms. Murtagh’s 4th class were learning about air resistance in Science. Air pushes against any object moving through it. This is known as air resistance. We conducted an experiment to investigate which material makes the perfect parachute. The perfect parachute will have the most air resistance pushing it up and will fall the slowest. We used plastic, card and fabric to create 3 different parachutes but we had to examine our variables before beginning. We decided that our controlled variables would be the size and shape of the parachutes, the height of the drop, the object attached to the parachute and the length of string used to attach the object to the parachute. We timed our 3 parachutes falling to the millisecond and the one that fell the slowest was the perfect one! Which material do you think made the perfect parachute?
We investigated pyramids and cubes. We discovered that pyramids are stronger structures than cubes. They are more sturdy and can hold up weight. We then looked at famous buildings that have triangles and pyramids. Watch out for these amazing triangles in the environment!!
