For this lab we learned about moon craters, how they got there and the types of energy associated with it. We talked about kinetic energy, potential energy, factors that influence the amount of energy in a system, and making equations for the energy. On this lab I got a meets- because I met the expectations for the lab but on one question, I didn't understand it so I didn't give an in-depth answer. My goal for next time is to get a meets and learn how to ask for help when I need to.

In this assignment we worked on distance v. time, speed = total distance + total time, and average acceleration = (Vf - Vi) divided by T.  The main topic was velocity and acceleration. I got a meets - on this lab because I did good except on the last question I was missing another piece of evidence. My goal for the next assignment is to get a meets or exceeds and if I dont understand or need help to ask. 

In this assignment we read an article about Newton's 3 laws and how they are associated with rockets. Then we made a brochure about each of Newtons laws and how they connect to rockets and how each law does something different but important. On this assignment I got an exceeds because I went above and beyond with my information. 

The specific types of energy and energy force in the egg drop would be, when your about to drop it, potential energy, and when you drop it and it's falling, kinetic energy. It shows Newton's 3 laws because it will stay at rest until dropped and it will parachute unless an outside force acts upon it. It shows Newton's 2nd law because the force when it comes down will show mass x acceleration. And it shows Newtons third law because the action would be dropping the egg drop device, and the equal and opposite reaction would be the egg falling and hitting the ground. In this experiment there is gravitational force because dropping the egg requires gravity, and there is friction force. What causes acceleration of a falling object is the force of gravity between the object and the ground. What causes that acceleration on Earth is the strength with which the Earth pulls on the object in the form of gravity. All objects fall the same rate in a vacuum chamber because there is no air resistance like space. Air resistance affects it by slowing it down. Mass affects impact force because increasing mass would be prone to decrease acceleration. So the greater force on more massive objects is balanced by the inverse influence of greater mass. I think the designs that were most successful at reducing the total impact force of the egg drop would be, group #2, (my group) because it had a soft landing and it didn't break, group #7, because it also had a light landing and falling and didn't break either, and group #8, because their landing and falling was so slow and graceful and their egg did not break either. 

In this assignment we built, tested, and refined film canister rockets. We worked on energy transfers, forces, and Newton's 3 laws. We built the rockets out of a film canister, paper, and tape. The first time we launched our rocket, it failed. We decided to change the cone because we made it wrong the first time and we shortened the rocket a little bit too. The second time we launched our rocket, it failed as well. Then we made a flight time comparison bar graph with each launch everyone did. Then we made a blueprint of the perfect rocket design, and lastly made an explanation. I got a meets on this assignment.

Our first test launch didn't work and it might have been because the bike pump didn't work but it might have been because our rocket had a hole in it. This time were going to start completely fresh with a new bottle and this time our egg will be under the cone in a dixie cup with cotton balls around it. We won't ductape  the fins whole anymore because I think that weighs it down. I also think we should add balloons for impact.

I wasn't here.

Our rocket went up around 27 feet and our egg didn't break. It worked because we made a new cone that is more aerodynamic and made new fins. I also think it worked because we put a lot more water in than we usually do.

In this project we learned about rockets and the forces contributing to make them go up and stay on course and go down. We also learned how to make our own bottle rockets and launch them. On this exhibition I got a meets - because our rocket could have been more refined but our rocket manual was good. My goal for our next project is to get a meets or higher and have more time to refine everything. 

Here is my rocket manual:
