 * How Eco-Friendly Is Our Cafeteria?**

In our project, we are trying to make the products that are sold in the cafeteria more eco-friendly. We would like to figure out how many of our products are recyclable and how many aren't. Our goal plan is too have the cafteria sell more recyclable products at an afordable price. This would also help reduce our school's MSW produced by students and teachers. If the cafeteria switches to eco-friendly products that could be recycled or composted, then the prices will be profitable for the cafeteria.
 * Introduction**

1. Clipboard 2. Computer 3. Pencil 4. Phone
 * Materials**

1. Observe items on lunch counter 2. Create a list of recyclable and another list for non-recyclable items for sale in the cafeteria (Joan Marsh) 3. Get finiancial information on how many non-recyclable items sold per school week 4. Find recyclable products that can replace non-recyclable products for sale currently 5. Search products that will stay within the school budget 6. Talk to school board about replacing products in cafeteria with more enviromentally friendly choices 7. Once the changes are made, inform student body on how to properly recylce cafeteria items
 * Procedure**

Independent Variable--- The amount of recyclable products in the cafeteria Dependent Variable--- The amount of MSW produced by students on our campus, the cost of products bought for CCDS

1. Don't run 2. Be carful walking around campus

 * Analysis**

Graphs:





Our graphs shows the constant buying rate of products in our cafeteria. The cups, lids, and straws seem to be the most popular, the chips, milk, and yogurts seem to be in the middle, and the apple juice seems to be not very popular at all. The second graph shows the profit of products bought in our cafeteria. It shows that yogurt sells for the highest, while apple juice, milk, and chips seem to be in the middle, and lastly cups come in way last barely costing anything. The third graph shows the comparison between the products we already use nd the more eco-friendly products. It shows that if the school did switch over to the more eco-friendly products it would cost more then it does for the less eco-friendly products we use now.

Was your hypothesis supported? Explain why or why not. Our hypothesis was not supported because when we researched and came up with the prices for the eco friendly products it costed more then what we were already spending. Therefore, it would not be a good idea to switch out the products in the cafeteria.
 * Conclusion:**

What are some of the problems with your experiment? Are these human or experimental errors? A problem that we ran into into during our experiment was that another group was already doing cups. When we ran into this problem we had to change our whole experiment slightly. This was a human error. Another problem we had with our experiment was that once we found the prices of the new eco firendly materials, they ended up costing way more then what we are already spending. Since they costed more, we could no longer change the products in the cafeteria. This is a

What challenges did you face collecting data? One challenge that we faced while collecting data that we had to start over in the midst of collecting data. We collected really two sets of data. While collecting the first set, we noticed that our project was not going to work out and we could no longer do it. So, we had to start over and collect a new set of data. This was the only problem we ran in to during collecting data.

What solutions can you propse from the conclusions? There is not really a solution that we an propose from our conclusions. We can't propose a solution because it turns out that, while bio-degradable may be better or our environment, it is not always price friendly.
