Wave Project
In this project we learned about waves. Electromagnetic waves, Energy waves all kinds of waves. We had to deign an experiment in which tested my hypothesis and driving question. This is the link to my final wave project report https://docs.google.com/document/d/1-_nL_2AIINKsU8rD70kLDcGKwrxEL9hwBRIjWnIdUww/edit
Design It Clean Project
POST PROJECT DESCRIPTION
In this project we were assigned groups . After that our group got together and brainstormed about filter ideas. We then proceed to construct them and test them. We tested them for things like water cloudiness and ammonia. I really liked this project because it challenged me to work in groups. It also provided me with knowledge about a world wide issue that I did not know much about prior to this project.

AREA DESCRIPTION
In Varanasi, India, the Hindu population, which is the majority, worship the Ganges River which is believed to be a god named Ganga. The Ganges flows through the heart of India down to the coast and is the largest river in the country. People bathe in it in order to cleanse themselves of sin. They also put the ashes of the deceased in the river so they can go to heaven. This rigorous use of the river is slowly hurting the it with harmful pollutants. In Varanasi many are suffering from extreme poverty and poor sanitation. This forces people to dispose of trash and even human waste in the river. Even as the political dynasty of India prospers, it’s largest sources of water is constantly being polluted.
Another large pollution factor is the leather tanning industry. Heavy metals such as chromium, titanium and many others pollute the water. These all come from the process that is used to tan leather. This leaves harmful chemicals pouring into the Ganges. In addition, the ganges is suffering from the poor treatment it receives from the candles and plastic poured into the Ganges in large amounts. This is such a problem because the Indian people worship the Ganges every dusk and every night pollute the river more and more.

PRODUCT DESCRIPTION
With an estimated cost of $6.00 our water filter will provide the people of the Ganges river with clean drinking and bathing water. Only needing any sort of water bottle ( that can be cut) cost is 50 cents to $1.00, a handful of pebbles which is free, a folded up piece of clean cloth, free, a small filter from a window screen or pasta strainer this would cost about $2.00, and tacs or a rubber band to hold the screen in place which on average cost, $1.99. The reasoning behind the multiple filtration components is to strain the water while keeping harmful pollutants out. For example, in the educational video we watched there was talk of many dead animals in the Ganges; to counter this we decided to include the window screen. As far as the rocks, we thought that it would benefit us to use a natural filter as opposed to exclusively a cloth and window screen. The thought process behind the cloth is that it will be the final filter that gets rid of any of the leftover pollutants and bacteria, and as far as we can see it works very well.

Snow Project Reflection
Snow Science is relevant to my life because I live in an area where it snows somewhat frequently in the winter. Understanding things like Avalanches and how they work could save my life someday.After the snow science project I know how important snowfall and water are in the western united states. Rivers like the Colorado support up to 7 states water supply and a little bit of mexico. Although the Colorado rarely flows into mexico because of the rapidly increasing population around the west. Snowfall contributes to the American west because the runoff from the snow adds to how much water is in the river.A science based skill that I learned is how to read an avalanche rose. If I find myself in a back country situation and need to know which direction is more dangerous I will be able to determine that if an avalanche rose is present. Something that I enjoyed during this project was the avalanche boards. I think it was fun to design my own avalanche slope. Also to see what trigger points set the avalanche off and were the fracture line occurred. I also like that you could choose your own variable to set off the avalanche.
Rocket Project
Introduction
‘Our water rockets that my group used were constructed of two 2 liter bottles. One was used to hold water and all of the PSI the other was used as a nose cone. Although they were the same sized bottles they were not the same shape. Our `variable that we had to test was the shape of the bottle. We thought that if the bottle shape was different then it would affect the height of the rocket. We then came up with a hypothesis which was if body shape affects height then we will determine what shape is more successful depending on how high it goes.
Procedure
Our variable for this project was body shape. How we went about testing this variable is that each member of our group used a different shaped bottle. We all used 2 liter bottles with different body forms and different ways of construction.
Constant Variables
Amount of water
PSI in the bottle
Weight
Location
A variable that we were unable to keep constant was weather.

We collected our data by having one member of our group stand a certain distance away from the launch pad and measure how high the rocket went, while another group member timed how long our rocket would take to reach maximum height. We then graphed our rocket by putting our data in the same way as in the sheet.
Conclusion
Our hypothesis was If body shape affects height then the rocket that is more streamline will go higher because turbulence will be minimized. Our results after testing this were inconclusive. We did not undergo enough tests with the two different types of rockets to prove our hypothesis. One of our errors in this project was not doing enough tests to prove our hypothesis. We were also inconsistent with many of our rocket launches with things like weight, PSI and water volume. After applying all of those things to all of our rockets to make them similar as possible our rockets and tests improved. A recommendation I have for future students is to make sure you have all of your variables and process determined before building and testing your rockets.
