This experiment tests the effect of parachute size on falling time. It is hypothesized that smaller parachutes will reach the ground faster than larger parachutes. The independent variable is parachute size with levels of 50cm x 50cm, 30cm x 30cm, and 15cm x 15cm. The dependent variable is time to reach the ground. The experiment involves constructing parachutes of different sizes from trash bags, string, and a GI Joe, dropping each from a set height, and recording the time to ground in a data table with multiple trials for each size.

1. Testable Question: What is the effect of the size of the material on the time it takes to
reach the floor ground?
Hypothesis: If the size of the parachute material is smaller then it will take less time to
fall to the floor ground.
IV: size of parachute material
leves:
DV: time it will take to reach floor ground
Constants: height, number of strings the G I JO
IV
Procedure:
1: Get materials, such as a trash bag, grab string,grab a g i jo
2: measure the trash bag at 0 by 50 cm
3. cut string at 1.5 feet
4. Punch a hole in the corners
5. put strength threw the hole and tie
6. connect string at the end with a inch left behind to tie to the g i jo
7.
DV
Procedure:
1. start with the bigger one that is at 50cm * 50cm
2. collect data and write on data table
3. repeat step 1 and 2 two more times
4. then drop the medium parachute that is measured at 30cm * 30cm
5. collect data write on the data table
6. repeat step 4 and 5 two more time
7. do 4,5 and 6 but with the smaller parachute measured at 15cm *15 cm
