ROCKET PROJECT
Rocket log/Rocket Entries
Example
1-1 (Day-Entry)
1-1
We are drawing our blueprint and naming our rocket. We discuss parts and who will bring what.
3-2
We bring in bottles and start sanding away sticky glue. Then cut bottles to shape that we need.
4-3
Start gluing bottles together to see rocket coming together.
5-4
Rocket gluing working on nose cone and parachute.
6-5
Remaking parachute after failed launch. Trying new design.
7-6
New design worked for test launch no parachute tho.
8-7
Still having trouble with the parachute deploying. Untying and retying the parachute.
9-8
Parachute still not working quite right will have to deal with for exhibition.

Rocket Reflection
The rocket launch Exhibition for my group was what I had expected. I anticipated it would go toward the right and the rocket would fly and how the parachute would not de plows. My group worked alright but still had some problems with our rocket that I was not too stoke on the fin were crooked. This made the rocket go to the side so it didn’t go to high in the air. I would change about this project is the rocket itself. I would make the whole rocket out of smart water bottles and take more time put the fin on straight and try to make it longer because seem that it work well for the other rockets.
I would tell to the class who are going to do this project next year is to find a partner that you get along with but not too much of friends so you don’t get in trouble. Also, that to make it out of smart water bottles and do a good gluing job and make it have the cone of the rocket good air flow. Make the cone so that the parachute can fit. I learn about my abilities or ambition level is that how much you can work it can blow up in your face so expect a low level of experience. I also learned that bottle can fly.

The Calculation for the rocket project are very hard if you don’t any of the data. First we had to find the height of our rocket. We took the data that the data table took at the exhibition. We took 174 times tan 60 and I got 91.7 m. For the average velocity we took the height of the rocket that was 174 times by 2 then divided by 5.61 and I got 32.69 m/s. Then I took 18.74 divided 5.61 and I got 8.7.
Rube Goldberg
The Rube Goldberg is when there butch of small of object start to main thing like punching a hole in a can. My partners were Jimmy and Coleman. Our punctured a can and sprayed a soda. We had to do calculation on 8 steps of the projects and sketch up.
