Map Project
Description In this project we made a map of a park using campuses and passes (foot step length) as well as a rope to find the angles of the corners. We then learned how to convert all the date we got on the ground into inches on a piece of paper. And make it a accurate replica of what the park should look like. We also learned how to use topographical maps and how they work.

Rube Goldberg
ReflectionEven though are rube did not work completely because we had to many places for human errors to happen. I still learned a lot in the project about team work and tools that I did not know before. And how impotent it is to have a good blue print in the beginning that you know will work and that you know you can make in the time provided.

Rocket Reflection
BY: Lacey Andersen
Our rocket started out with a really cool idea to use an umbrella as our parachute. We did not think it through very well and then once we started building I realized how heavy it was going to be. I got very worried about the performance but it was already to late to make a whole new rocket so we worked with it.
Our plan to use one bottle for are combustion chamber worked very well. We were able to spend more time on the rest of our rocket. Like the umbrella, fins, and putting all the pieces together. The idea of having an umbrella being able to stay closed and then open when the rocket starts plummeting to the ground looked really good on paper and in test flights it had potential. We never considered wind into the equation on how the umbrella was going to fly. If it was windy it was going to keep the umbrella closed not letting it do its job. We prayed that it was not going to be windy on exhibition night for that reason. Our fins were pretty heavy but worked well to keep our rocket-flying straight even in the windy conditions of exhibition. Exhibition night ended up being very windy; our umbrella did not open and our rocket broke two fins when it hit the ground. On our second flight the umbrella opened but did not work like planned. I wish that we could of launched are rocket another day that wasn’t windy because I thought that the umbrella idea was going to work. I will never get to find out if it would of worked or not in good weather conditions.
I wish I could do this project again and be able to build a better rocket from all the things I learned and the mistakes we made. I do not recommend using an umbrella in the time frame we had to build it in. It made it very heavy compared to the other rockets. Considering how heavy it was it did not go very high at all. We had to make really big fins to stabilize it, in tern adding to the weight. For this rocket weight was a big deal because every body was trying to make the rocket that went the highest. So if it was as light as possible it makes it more likely to go high. I would love to make another rocket and focus mainly on making it lighter and having a good parachute. I think these are the most important things to focus on when making these rockets.
I thought exhibition was very good. There were a lot of people that came to support the freshmen. Including upper classmen, which was the coolest part for me having the support from all the other kids in the school. Mr. H did a really good job with organizing the whole thing; as well I was amazed by the launch pad that he built for the rockets to launch off of. I am really starting to enjoy exhibitions because it is a nice way to include the public into Animas and our projects. Its fun to be able to get the chance to share our work off. It makes me feel proud of my self to be able to show all my work off. Even though are rocket launch was a fail I still had a lot of fun being able to watch all the other rockets my classmates made.

Phisics Behind the Rocket
Newton’s first law
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon bye an unbalanced force. With are rocket we had a lot of unbalanced forces acting on it. For instance when it was flying through the air the rocket put more force on the air and gravity then it put back on the rocket intern letting it fly up into the air. Ones the rocket stooped being propelled and air and gravity had the same force acting on it as rocket, it stopped flying up in the air. Then falling down to the ground because gravity was the bigger force. |
The rocket did not stay in motion at the same speed because of all the out side forces acting upon it, like wind, gravity, and air friction. To conclude the rocket goes the directing with the less force acting on it. Making it go up, down, right and left in different circumstances
Newton’s Second Law
“The acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. [F=ma)”. Basically this means that the force is equal to mass multiplied by acceleration. This law applies to rocketry by saying that the larger the force given to the rocket, the faster it will accelerate. So for our rockets, the higher the PSI of CO2 is, the higher it will go and the faster it will accelerate. The force that makes the rocket go up is the pressure that is collected in the bottle of our rocket by pumping the CO2 into the (half filled) water bottle. This pressure accelerates the gases one direction, and the rocket in the other. The acceleration is also effected by the mass of the rocket. A small lightweight rocket will accelerate much faster than a large, heavy rocket. All in all, Newton’s second law tells us why our rocket goes at a certain speed and a certain height.
Newton’s third law
Newton’s third law describes that for every action there is an equal and opposite reaction. In the case of our rockets, they are able to be launched into the air because the water and carbonized air exerts an opposite and equal force on the bottle when the trigger is released. This in turn, boosts the rocket with the energy from the ground, up into the sky.
