Forces and Motion Quiz #1: I got an 8/15 on this quiz because I really didn't understand the topic. Something I could do better next time is study a little more.
Forces and Motion Quiz #2: I got an 8/10 on this quiz which is much better than last time and I am really proud of that. I studied for this quiz beforehand, which means I met my goal from last time.
Forces and Motion Quiz #3: I got a 5/5 on this quiz, which is an exceeds. This quiz was about kinetic energy, potential energy, and egg drops.
In this anchor chart we covered newtons laws, different forces, and equations to find different forces or things. I give my effort on the anchor chart a 4/5, because I feel like I put a pretty good amount of effort into my anchor chart, but sometimes I didn't do it right after science class which made it harder to do later. My anchor charts have evolved pretty well because I have gotten more comfortable with them. I think I really improved on how much I write and what I write about each topic on the anchor chart. I can be prepared for quizzes/tests in high school by taking notes and studying.
In this assignment, we worked on connecting Newton's 3 laws to a rocket launch to help us better understand how to conduct a rocket launch. One fact I learned from this assignment was that rockets don't push off of the ground to take off. This assignment will help me with my rocket launch exhibition because I can use newton's laws to help me create a stable rocket.
We did an egg drop challenge. This egg drop experiment demonstrated different types of energy through potential energy doing an energy transfer into kinetic energy. The potential energy is stored in the egg before it falls, and as it falls it builds up more and more kinetic energy. Kinetic energy and potential energy also transfer through mechanical work, such as gravity pulling a falling object, or lifting an object. The potential energy that my egg had before it dropped was 6879.1 because you multiply the mass of 76.8g by the height, 9.14, by the gravitational acceleration, 9.8. The average velocity of our egg was 2.6, because you divided the distance, 9.14, by the time, 3.53. The average kinetic energy was 259.6 J, because you multiply the mass by the average velocity squared times ½. One thing I learned from this is that as mass increases, so does the impact force, and there is proof from Newton's 2nd law, f=ma. A very popular and useful design were the big parachutes because it slowed the egg’s descent by a lot. A design that I think would be useful for the rocket launch is keeping the egg compact with cotton balls and protection around it.
