As Project Collision shifted due to the Covid-19 virus from a collaborative school project to an individual home project, a big challenge that I faced was getting the materials and finding a suitable drop zone for my testing. To overcome this challenge, I asked my parents to go with me to the supermarket and buy all of the materials and tell me where I can put my drop zone as my dad doesn’t like his apartment’s floors/wallpapers damaged because of my testing. Before this project I used to think that I could just build the parachute and see how it works out, now I think that it is very important to research and test before deciding the best variable to use. For example, for my variable, we had to research what lengths of suspension cords we should use for a __cm parachute. Then we decided the 3 best lengths of suspension cords for the parachute. After that, we cut out the parachute that the other team decided was their variable and tested all 3 of our lengths and decided which one, we were going to use on the final parachute. Finally, our whole team came together and pitched to each other which one of the variables we are going to use for the parachute. Looking back on Collision, I learned that to have accurate testing you have to drop your package at the same spot every time to get a most accurate answer. One area where data supported my thinking was where the 50cm suspension cord showed that one drop hit the target then bounced off my 20cm. I think that this happened because I might have moved my hand when I dropped my package.
