Daily Log- On this page, we will be telling you about the tasks that we completed this day and what we did in brief detail.

April 21,2011- Day 1 Tasks- 1. Learn About Project 2. Pick Groups 3. Choose design challenge off list 4. Start planning design and begin collecting materials

Log- This was the first day of the project and we were told to choose our parteners. Lian, Levi and I chose to be in the same group and we decided after looking at all of the designs that we will do the water rocket challenge. Since we were in groups of three, we had to do at leat two rockets. We started out by planning out the design by drawing it out on a paper. Then we decided that all of us will bring different sizes and shapes of bottles.

April 25,2011- Day 2 Block- 9:50- 11:10 Tasks- 1. Collect Materials 2. Check which bottle fits best for this design 3. Begin Building

Log- On this day, we collected all of our materials and a bottle was chosen for which we would use to make the rocket. We began first to cut out the fins of the rocket which were made from styrophome. Then, we took those fins and we glued them onto the bottle. We also taped magnets onto the bottle so that it would be evenly weighted, this way the rocket would not lop side and go in the wrong direction. By the end of class, we had a basic model and most all of the materials were collected.

April 27,2011- Day 3 Block- 8:05- 9:30 Log- All we did this day is tape the middle of the bottle together once we found out that we could not have it cut open in the middle. This is all we did becuase we worked on the sub levels for most all of the class. Next class we will begin to make the parachute. April 29, 2011- Day 4 Block- 1:30-2:55 Log- We too a small bottle and we added it to the bigger bottle as a holder for the parachute. We taped the two bottles togther at the right side so that the bottle would not completely come out. We also need it to come out when the bottle is falling down.

May 4, 2011- Day 5 Block- 11:20-12:45 Log- Today we had our first test run which unfortunatly failed. However, we were able to learn from our mistakes and we now know how ti fix our water rocket. We need to fix up and close all holes so that there is no water leaking when the pressure in the bottle increases. We also made a parachute from a piece of cloth and string, which we found in class. We tested the parachute and it ended up to work properly, as the rocks were able to glide to the ground.

May 18, 2011- Day 6 Block- 10:00- 11:20 Log- Today we tried our second test of our water rocket. We learned from our mistakes, so this time we did not use two bottles that were cut in half. We took one sprite bottle and we added fins to the ends. Our first test run was pretty successful, however the parachute was not coming out at the peak of the rocket's trajectory. We also tried the rocket without water as a side factor. We noticed that without water, the roccket did not go as high or as far. We also noticed that the wind in the air and the amount of water in the bottle heavily affected our rocket as sometimes the rocket would go up towards the space of the wind. All we need to do is perfect the parachute to the time that we want it to come out and the amount of water perfect for a good flight.
