The size of the canopy does not affect how quickly the parachute falls to the ground. The results showed that the small canopy (5cm x 5cm) fell to the ground the quickest and the larger canopy (20cm x 20cm) took the longest to fall to the ground. The results of my experiment fail to support my hypothesis. I have learned that the reason the smaller canopy was able to fall quick is because it has a smaller surface area which means that there is less air resistance pushing up on the canopy and slowing it down as it falls to the ground.

Ionic compounds are made of ions, and yet the overall charge of an ionic compound is neutral. why?
