Topographic map
We used compasses and paces to measure the perimeter of the zone you see on our map. We spotted a person, took a bearing and counted our steps to that person. We continued that process until we had counted steps and took bearings in between all of the four rocks. When we got back to the school we figured out how far one step was and created a scale in order to map out a smaller version of this area on a poster board. Using a protractor and setting north at the top of the paper, we measured our bearings onto the map and scaled down the steps we took. The lines you see on the map are called contour lines, each line is five feet in elevation away from the next so when the lines are closer together the terrain is steep. We used google earth’s 3d tools to figure out where to put the contour lines. Contour lines are very helpful to have on a map because they help you figure out where it will be easiest to hike. Walking a zone and then scaling it down and mapping it helped us to gain more spatial awareness and to view maps in a different way. Going out and seeing a large space and then mapping it on a small paper helped us learn how to read maps and realize how big the areas displayed on maps really are.
Rube Gold berg
|
Reuben Garrett Lucius "Rube" Goldberg (July 4, 1883 – December 7, 1970) was an American comic writer , sculptor, author, engineer and inventor.
He is known for a series of popular cartoons of complex gadgets that in the end makes a action that is very small. In my Rube Goldberg we are making a bowl of cereal. we have to have 15 steps on the Rube Goldberg and it has to last 15 seconds. |

Rocket Reflection
The rocket launch in physics was one of my favorite projects of all time. We have built for two soiled weeks and we just launched. Orion was my partner in this project and we built two rockets after the shahin rocket design. I loved the Rocket launch our rockets flew great and high. We worked so hard for not that much height but it was a great project. Building the rocket was hard because of the design we were following. We started out with 6 smart water bottles and 1 a liter bottle. After getting all these bottles we decided to make two rockets instead of one. This decision would help us in the long run and it helped us. Now to talk about the launches of the rockets. We started out at the end of the line because our rockets were being launched at 80 and 100. The first of our rockets that launched was not that successful. The second rocket that launched with pride it went about 200 feet. Up until the moment that he launched our rocket it was all dreams. Once it had launched and fell back to the earth.

Conclusion
After the fun and excitement of the rocket launch then comes the calculations that aren’t so fun and exciting. The first calculation that we did is finding how high my rocket with tangent. We first used the distance the observers measured the angles from to get the tangent with this. My angle was 51 degrees and the distance the observers were from the launch pad was 53 meters. After all these calculations I found out that my rocket went 16.2 meters up in the air and its hang time was 4.93 seconds. Next we calculated the average velocity by see how far the rocket went in the air and how long it was up in the air. For my rocket it went 16.2 meters in the air and stayed in the air for 4.93 seconds so I got a average velocity of 17.3 meters per second. Now you see that there has to be an error because my rocket went 16.2 meters up but should have gone quadruple that. This is the next thing the theoretical hang time and the hang time. These are different times for me the theoretical hang time was 5.917 seconds and my hang time was 4.93 seconds. This is due to percent error calculation. The measurements were not the same they were 16.5 % off because of the wrong angle and the difference in the parachute and air friction.
