Wave project
Filter Project
I didn't think that people in third world countries had such bad experiences with water but now I do. I also understand that there are people who are trying really help. The most that I will take away from this project is that any one can "help" because even though our filter wasn't the best we were still able to have a sense of what the people in Varansai India go through and it really is an eye opener.
Our filter is a funnel shaped cone filled with a mixture of cloth, sand, grass, coal, and stones. The main filtering in order of effectiveness are: Cloth, sand, coal, grass, stones. The funnel was constructed in a series of layers of sand, cloth, and coal, using grass to hold them together and rocks at the end of the funnel to keep everything in place. Our areas biggest problem would correlate with the ammonia test, which in turn resulted in that being our best test.
snow science awareness
1. In what ways was Snow Science relevant to your life?
I snowboard a lot. Learning about avalanche safety and snow science gave me a lot more confidence in being safe and more conscious of my surroundings.
2. What do you now understand about the role snow and water play in the American West (be specific)?
3. What skill did you develop through engaging this material?
4. What is one thing that you particularly enjoyed doing/learning, what is one thing you struggled with/did not enjoy?

Water Bottle Rockets!
My Rocket
For my rocket I stuck to a very simple procedure. To make my rocket I used cardboard, duct tape, 2 two liter bottles, hot glue gun and five pennies. I first cut out pieces of cardboard into the shape of finns. Then I cut the second two liter bottle at the top and connected that to the top of the first bottle using duct tape. After this I connected the fins using duct tape as well. Once the fins and my cone were connected to the body. I took the lid off of the cone and then I glued the five pennies into the lid with a hot glue gun. If you want, you can spray paint your rocket like I did. It only takes a few minutes and is really fun to do. This is how I built my water bottle rocket. |
Introduction
The testing variable we chose was the amount of water in the bottle because we wanted to know if it would affect the height. Our question was how does the amount of water affect the distance of the rocket? Our hypothesis was if the amount of water affects the height of the rocket, then we can find the amount of water that will make the rocket go the highest.

Procedure
We added water to our rocket before going outside. Then we went out to the launch pad and had two other people help us to connect the rocket. Once it was connected we had the same two people take an angle measure and they recorded the angle that the rocket went its highest. There were also people who pulled the pins so the rocket could take off. There was also a person using a bike pump to keep the P.S.I at a certain pressure so the rocket had a constant pressure. Once the rocket came back down to the ground we collected the data that the other people collected so we could conclude our testing This is the procedure we took to test our rocket(s).

Data
Conclusion
In relation to our hypothesis, we discovered that the rocket went the highest when we put 1500ml of water in the bottle. The only difficulties we encountered were with one test, so we just re-did the test. When we finished testing, we knew exactly what amount of water would make our rocket go the highest. We would recommend to keep your rocket design simple. That way if gets lost or destroyed it will be easy to repair or re-create.
