This science fair project was performed to investigate the relationship between the shape of a parachute and its drop velocity. Triangular, square, rectangular and round parachutes were used.
1. For this science fair project, the independent variable is the shape of the parachutes’ canopies. The dependent variable is the drop speeds of the parachutes. How long does it take for the parachutes to reach the ground? Measure this using a stopwatch. The constants (control variables) are the surface area of the canopies, the weight of the nails, and the height from which the parachutes are dropped. 2. Cut a triangle, a square, a rectangle and a circle from 4 plastic bags. Each shape should have an area of 500 square centimeters. Calculate how long the sides and diameters .....
