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 a lack of materials and not enough testing space.

To overcome this challenge, I used whatever material that I can find to make a parachute that fits my design. During this period, I think the appropriate mindset is that we cannot focus on being very precise on everything. The goal is to test and analyze, then make a decision.

Before this project, I used to think that all parachute works the same way, now I think different types of chute work better in different circumstances. For example, the bigger parachute can create more air resistance than smaller parachutes, but it loses some of its accuracies due to the amount of air resistance it creates.

Looking back on Collision, I learned that support your claim with evidence is very critical because it makes your claim more solid so it could convince people about your decisions on the design.

To show data means you did reliable tests and analyzed the results. One area where data supported my thinking was the average drop speed of my iteration 2; it helped me because it clearly showed how iteration 2 did better than iteration 1.
