Design it Clean Project:
Project Explanation
For this project we had to create a filtering device that was low cost but still reusable for third world countries. We worked in groups to create a filter for a poor village in Kenya.

Snow Awareness project:
For living in the American west snow is an important part in our ecosystem. This means it is important in my life because it gives us all our water supply and fills up our rivers. We need all the water we can get, because it rare to rain. Now with my larger understanding snow gives us most of the water that we consume in the rivers. Also we use all the water from the Colorado River that it can’t reach its delta. So as the American west we need to lower our use of the water to let Mexico become an oasis again. The reason it lost its water was because when the river was divided the water count was much higher then usual and though out most of the recent years it has been a drought and Mexico has gotten little water. Knowing the amount of water consumption in the west will help you realize that we are over using this natural product that doesn’t even reach it’s end.
When we were creating our diorama we had to take in all of all of the information and still have it all work together, we had to look at all the material we were given and show it. Some of the material we had to involve was 21st century skills and science skills. Some science skills we used was comparing and contrasting observations on avalanche triggers or stress fractures. A 21st century skill is critical thinking or problem solving because when we were creating the diorama we came into a few problem on how we were to build the underneath frame and to use the clay in the most effective way. During the cores of making the project on part was my favorite was the whole creation of the diorama because it was fun to create.

Water Rockets:
Description of rockets: "Leaky"- Our first rocket was a 2 liter smart water bottles rocket. This rocket did leak quite a bit. The rocket still shot though and pretty far for only going to 25psi. The bottle had a crooked side to it that we balanced out by making one of the sides heavier.The cone fit the rocket well with a cut folder inside and paperboard. The fins on both rockets were the same size. Whale- was the single two liter bottle with the same material for the nose cone and fins, just fit to the rockets size.
Why we chose our variable: We chose our variable, diameter, for a few reasons. First of all, we wanted something that would be a bit more of a challenge to control. We also wanted something that would have to include at least two rockets. For these reasons, we chose to use diameter as our variable.
Our question: Our question was "Does diameter affect the height of the rocket?". We could easily measure the height of our rocket by creating two different rockets with two different diameters and the same volume.
Our hypothesis: Our hypothesis was written correctly because it was an if then because statement. Also it had all of the criteria it needed. Our hypothesis stated: if diameter affects height, then a smaller diameter will go higher because it is more aerodynamic.
How we tested our variable: When testing our variable (diameter) we had to keep everything the same except for the diameter. We would launch the rockets and record the height. We did this very many times so we could get very accurate data. We had Ruby stand 10 meters away from the launch module and measure angle of the rocket at its peak.
One variable we couldn't keep constant: The one variable that we tried to keep constant but couldn’t was nose cone size. This was hard because one size would be too big for the other rocket, and the other would be too small. In the end, we just fitted the cone to each rocket individually rather than having the same sized cone. However, we could have found a middle size.
How we collected our data: We collected our data by finding the height. To do this, we used tangent. (See below). We did multiple tests to get accurate results.
How we graphed our data: We graphed our data using google spreadsheets. We decided to use a bar graph because it gives a visual representation of how our diameter affected our height.
Conclusion: In conclusion, we found our hypothesis to be incorrect. Our hypothesis states that if diameter affects height, then a smaller diameter will go higher because it is more aerodynamic. This was incorrect because in order to keep our volume constant, we had to merge two bottles together. This caused a leak in our rocket. Also, it was bent towards one side. This created a flaw in our testing. Furthermore, we needed another point on our graph. Our last rocket that was built wasn’t able to get off the launch pad because of a major leak. For the most part we had a very successful study between the different sized rockets. The leak in our rocket was very difficult for us. Furthermore, we needed at least 3 sets of data, so we took on an additional group member. However, one of our rockets ended up not working so we only had two sets of data. To compensate for this, we did three tests per rocket to achieve more than two data sets. Our recommendation for other students building rockets is to never give up. Our teacher told us a few times that our rocket would not fly because it leaked, however it still flew higher than others. You need to be able to persevere when it gets hard because it is all worth it in the end.
