The Methodology Behind The Map
By: Orion, Skylar, Annie, Quinn, and Sean
The first thing that we did was we measured the points between the four rocks that we spray painted in paces. We counted how many paces at what degree from one rock to the next. We then on our map converted paces to millimeters and used a protractor for the degrees. We were able to see the terrain from a birds eye view and then used the elevation to place the contour lines. The contour lines show the type of terrain and the elevation of the terrain. This project helped us to see how space is related from real life to a piece of paper.

Rocket Project
Day 4 Entry 1: Today we put the two liter bottles together and glued them.
Day 5 Entry 1: We put the fins on and went looking for a parachute.
Day 5 Entry 2: We found a parachute and put it on our rocket "Rocket"
Day 6 Entry 1: The first test launch. Successful parachute, terrible height.
Day 6 Entry 2: BOOOOOOM!!!!! Explosion.
Day 40 Entry 1: Started on new rocket still called "Rocket"
Day 41: Entry 1: Launch went great. The parachute deployed. Successful launch.
Day 45 Entry 1: Got a good grade for the rocket.

Rocket Reflection
Sean Thornton
The rocket project was a really fun project. I would really want to do it again if I had a choice. Our rocket blew up. I then did not make another one until after the exhibition. If I had done it on time I would have gotten a better grade and have a better over all grade.

Conclusion
At the exhibition our rocket took off at 38% degrees angle and had a maximum height of 24.1m, the observers were 30 meters away from our rocket. To calculate the maximum height we multiplied the distance from the observation to the launch pad in meters by the tangent function of our rocket’s flight angle. To find the average flight velocity, I multiplied the rocket’s maximum height by two then divided it by the flight time 6.61 seconds. This gave us the average velocity of 7.30m\s. The theoretical flight time of our rocket was 4.4 seconds. We calculated this by dividing the maximum height by 9.8(m\s) by 0.5. Then you find the square root of the number and multiply it by two this gives you the theoretical flight time. After doing the calculations we figured out that there was a 50.22% error for our rocket. Our rocket’s flight was good because it almost went straight up and had two working parachutes that deployed and worked.
