What did I do?
Me and my class did the egg car challenge, what we had to do was keep the egg in the car safe and not cracked after a ramp, we had the materials: tape, wheels, straw, and 3 sheet of paper, me and Fiona first we made the base which was a long paper, after we cut the straw to two small pieces and put it to the tires, after we use tape to stick it to the paper, after, we made a cylinder and put the egg in it and lastly, we added crumple zones.
What did I learn?
I learned Newton’s laws, for example when the egg car stops the egg in it doesn’t want to stop so it would fly out, but if we add a crumple zone then it would make the crash smaller, I also learned that if the car is moving then the friction force is smaller and the applied force is more.
What worked?
What worked was that the egg only cracked a little bit, also the speed worked our egg car was very fast which we achieved our goal on speed, also the wheels we removed the rubber thing which helped on the speed but also fixed the problem that the egg car would just stay at the top or stop in the middle and other problems.
What did not work?
What did not work was that our base was to light which is a problem because the washer and the egg would make it collapse, so the egg would crack a little bit, also our crumple zone was not good which didn’t help that much on the stop.
Personal relevance
I now know that we should add crumple zones and a good and strong base but as well as a good wheel because wheel can help on moving, but we also need to add airbags and seatbelts, I like this egg car challenge a lot.
