Our teacher suggested to use umbrella fabric to make a parachute. It seemed reasonable, so we started with the job. We took the fabric off the umbrella, and attached a weight of 350grams. We dropped it from a height of approximately 7.5 metres and it took 2 seconds to reach the floor. We tested several times and the result was the same. We figured out that the velocity was around 3.75m/s at that moment. We experimented several times and the result was the same. We dropped the weight without a parachute twice, and it took 1 second in average for it to reach the ground. We came to a conclusion that the parachute is definitely doing its job, but we needed to decrease the area of the parachute to cause less air resistance.
Jiwoo Park Part of our outreach program will include running 2 hour workshops on space science for local school. The projects will be STEM based focusing on design and engineer mixed with some good old fun!!
