Design It Clean
The design it clean project was based on the filtration of water in specific areas. We each were given a location, each group member had to do specific research to find what its like in this location and how does their religious and beliefs effect the water. Also we needed to find that is polluting the water. Once we figured all of that out we had to design a filter that would remove that pollution leaving the people and community with clean healthy water. After we designed and built our filter we had to test it with dirty or toxic water and see what was removed after the water had gone through the filter.
Religion and Culture:
We are constructing a water filter specifically for India’s inhabitants near the Ganges River. This will help filter the water in small amounts for the residents at their disposal. The method is fairly cheap and produces a 99% success rate of filtration. Because of their religion, the Ganges is known as a dump ground for religious practices. Their religious foundation surrounds the practice of Hinduism. The River is a sacred place for Hindus because it’s seen as a personified form of an important goddess, Ganga. They believe that the river will cleanse them of their sins and that when they or loved ones die, their souls will be redeemed if they die within the city. They participate in rituals to reach out to their God. These rituals include bathing in the river to cleanse, dumping cremated bodies in order for them to reach paradise, and other ceremonies including releasing candlelit floats into the water to honor Buddha and Ganga. The people who practice these rituals believe that the God is the river and therefore cannot be harmed by everything they dump into the river. The culture surrounding the Ganges River is very complex with several different Gods and Goddesses linked to it. In general, if you live near the Ganges River, you are likely to have sustenance and magical qualities. Modern day citizens of India practice yoga alongside the River. The city Varanasi (close to the river) is deemed a holy city where visitors travel to access the Gods and Goddesses coming down to Earth. It’s an important industrial city with an abundance of art, education and craft.
Explanation of filter:
The filtration method we are focusing on is the biosand filter. This is made up of 4 layers, including the water. The bottom layer is gravel, this prevents the straw from getting clogged with the sand. The next layer is a layer of smaller gravel, this layer supports the filtration sand and keeps it from going into the bottom layer on gravel. The third layer is the sand, this removes pathogens and suspended soils. The last layer is a sponge, this final layer helps prevent disturbance to the sand layer as well as protects it when water is poured into the filter. As the water makes its way to the bottom of the filter, it will fill within the pebble layer and flow into a straw where the clean water drains out.

Snow Science
The poster we made is showing specific avalanche terrain in areas that it could occur on a mountain. Snow and scow science has a large impact on my life because where I live snow is all around me as well as mountains.
Helmets
Rocket Write up
One way to study and test physics is by performing the rocket project. My group of three constructed some research in order to determine our variable. In the end we decided to test the fin variable. Each group member was assigned to a fin size. All other parts of our rocket were the same besides the fin size. This way when we tested we knew almost 100% what was causing the rockets performance to increase or decrease. All of our rocket bodies were made out of Smart water bottles and painted each with different colors. Our cones were also the same in shape, size and mass. The three different size of fins we made were:
We choose this variable because our researched showed that the fin size and shape can affect the flight of the rocket dramatically. This is tested accurately because it’s the only variable that is changed throughout the whole rocket.
Our Question: Does the size of the rocket fins affect the flight of the rocket?
Our Hypothesis: If a rocket has six small fins it will fly the highest because with more fins the stability is greater.
Procedure:
The procedure of this experiment for my group started by constructing our rockets with our variable, question and hypothesis in mind, which is stated in our introduction. Then we continued on to the test launches of our rockets. To do this we filled our rockets with water to a point we found was best. Then we put our rockets on the launcher and used the bike pump to create pressure. My group chose to pressurize our bottles to 30 psi considering they are smaller than your average rocket. We would then measure the angle, the distance away from which we were standing from the launcher and the time it took to complete the fight. All in preparation to find the height of how high the rocket flew.
We went about testing our variable by launching our rocket with different sized fins while all of the other variables stayed the same.We did this by all three of us using cardboard and hot glue as our materials so the only thing that was changing was the size of our fins. Then when we were ready to launch we filled our rockets with water and made sure to keep the pressure at a constant rate of 30 psi. Some variables we were not able to keep constant were things like the weight/mass and dimensions because we tested the size of fins which means a different weight because of the amount of material used. The variables we did keep the same were:
Shape: Long and thin (Smart Water bottles)
Pressure: 30 psi
We collect this data by shooting our rocket(s) during the class period. First, we had to fill up with water, we needed to make sure each of our rockets have the same amount of water in them. We found a specific line in each of our water bottles, we all had Smart water bottles, and filled it up to that mark every time. Next, we had to mount our rocket(s) once we had our rockets mounted we measured the distance from the launcher to where we were going to get the height angle. Once we got that we launched our rockets and as we did so we timed the amount of time it took the rocket to be launched until it hit the ground. We also got the angle from where we were standing to the peak of the rockets launch. Once we collected this data, we created a graph to show the height of our rockets. We completed this by using the equation height= tangent of angle x distance (from launcher). The tangent, the equation to find the tangent is opposite side/adjacent side of the triangle.
