In this unit, we built egg cars, slid them down little paths and tested if they could protect the egg from the concrete block. The cars were made of paper, plastic wheels, and tape. But we also had constraints. One constraint was that we only had 1 meter of tape, so we also had to be resourceful. During this project, I deepened my understanding of Newton’s laws, because I also saw usage of Newton’s Laws while we did the challenge. For example, When the egg car hits the concrete block, the block hits the car with an equal and opposite reaction. Also, Newton’s 2nd Law states: The bigger the mass of an object, the more force needed to move it. I also saw that Law in action when I saw the other group put weights on their car to slow it down, so that it won’t hit the concrete block with such big amount of force. One thing that worked well in my design was that in the car seat, we put a seat belt and airbags (crumpled pieces of paper) in our backseat. But a few things that did not work were that when we were building it, our car seemed to be more wobbly and unsteady than others. One thing I could improve is that I could have still used more tape and paper to make the car small but steady. Now that I’ve gone through this unit, firstly I know a lot more about cars now, that they have a crumple zone and that they could have airbags. Now, I also know that wearing a seatbelt is REALLY important, so I will ALWAYS wear my seatbelt now.😁
