Map methodology
To Measure our bearings and paces in the field, we had one person who had a compass and used it to calculate the direction we were walking in from one landmark to the next around the perimeter of the mapping area. We had someone counting their strides between the points, we had the same person do that the whole time so that their were not different stride lengths. We also had someone marking waypoints on the GPS which tells you how high you are and exactly what your latitude longitude is, and they also wrote all of the information down. Once we had all of the information that we needed, we used it to create our map. We drew a compass so that we could point the protractor North every time. Then we placed the first point and used the protractor to find out which direction the coordanance of the next point were at, we used a scale so that one pace was a certain distance on the map and then once we had all of the points we just connected them to get the boundaries of the mapping area. we used Google Earth to plot our contour lines by flagging all of the landmarks on the map and then we put in the high and low points on the map and then from the low point added 5m and then traced what the perimeter looked like and then added another 5 and traced again until we had this topo map. contour lines are lines that join points of equal height above sea level, but their are also topo maps of the sea floor. These lines can be used to see what the terrain of a certain area looks like, a lot of times hikers use them to find routs up mountains. This project not only taught us how to use Google Earth to make a topographic map and how to use a GPS, but also taught us how to use compasses to navigate from one point to another which we can use throughout our whole lives and by the end of the project we all had a good idea of what the terrain looked like in the area that we mapped.re to edit.

The Rube Goldberg Project
The Rube Goldberg project was the most recent and most fun project that we did in physics. The 'Rube' was a contraption built on a 2'x2' piece of plywood consisting of 15 steps, (energy transfers), that had to last 15 seconds or longer. This hands on project required focus, teamwork, and critical thinking to come up with a product that worked consistently and met all of the requirements.
The rocket project
Rocket Reflection
The rocket exhibition was very successful for my team. Our hard work paid off and our rocket launched properly and the parachute deployed. Although our parachute was very close to not working, it pulled out of the nose cone just in time for it to save the life of the Taco Tuesday. My group was very proud of our project when we realized that we had worked hard enough to make our rocket successful.
I think that the people in my group worked quite well together. We all enjoyed working together and we all pitched in to make our project a success. Although I chose one of my good friends as my partner, we managed to stay on task and not screw around during project work time.
If I could do the rocket project again, there are definitely some things that I would do differently. I would make my fins out of more smart water bottles because the plexiglass was too heavy. Also, I would create a better extension such as I had on my rocket before it broke. We worked efficiently during project work time but I think we could’ve used our time even more systematically.

Rocket log:
1. Day 6: Put fins on our rocket and make the nose cone
2. Day 7: Rocket imploded and then exploded
3. Day 8: Yesterday our rocket broke so now we have to remake it.
4. Day 9: Launched but isn't working.
5. Day10: Just finished nose cone and parachute.
6. Day11: Today we are remaking our chute and making it awesome.
7. Day12: Final test launch. Parachute deployed but wasn't perfect.
8. Day13: Today making final check ups on rocket. preparing to fly.

Conclusion
After the exhibition we had to make a lot of calculations to figure out how exactly how our rockets flew. The exhibition was set up with a data collection table 174ft away from the launch pad. The data team recorded the time our rockets were in the air and the angle of the apex. After the data sheet was printed, we used these numbers to figure out the theoretical flight time, the height of our rocket, and the speed the rocket accelerated at. The first calculation that we made was to find the maximum height. The formula is 53tan__º=__m. This will tell you how many feet up the rocket actually went. The second step is to find the hang time. Use the formula t=√(MAXht/0.5a) to find how long your rocket was in the air. To find out the percent error you can use this formula: (actual height/theoretical height)x100=%.
The maximum height for my rocket was 327ft and the hang time was 6.76 seconds. The percent error is calculated by the formula: [(actual time-theoretical time)/theoretical time]x100=%. The percent error will be bigger if the parachute deploys because it lengthens the hang time.
