Hypothesis 
 My hypothesis is that  the container without grass will have more erosion than the container with grass. 
 
Abstract 
 Purpose 
I am trying to find out if more erosion will occur if there is grass on the ground or not. 

Procedure 
I took 2 bins and put the same amount of dirt in both in one I grew grass. 
After the grass grew I put the containers next a fan fro 2 min. each 1 at a time. Then I recorded the data. 
Then I poured 2 1/2 cups of water down the slop I had made with the dirt and then recorded the data.  
Lastly I made the graphs and charts to show what I learned. 

Conclusion 
My hypothesis was correct the container with the grass did not erode as much as the one with grass. This meant a lot because it means that there is away to prevent erosion from occurring. 
 
Materials   
1. 2 plastic bins
2. Potting soil 
3. Grass seed  
4. watering can 
5. Water 
6. Sheet 
7. One electric fan
Procedure   
1. First I took 2 bins and put the same amount of dirt in both of them. I planted grass in one of them and left the other one how it was.
2.After the grass grew, I put the containers next to a fan 1 at a time. I turned the fan on and let it sit for 2 min. Next I recorded how much erosion had occurred.
3.Then I poured water down the slope that I had made with the dirt and then recorded how much erosion had occurred.
4.Lastly I made all of the graphs and charts to show what had happened.
Results   


My experiment turned out exactly as I thought it would. The container with grass in it did not have as much erosion as the one with out grass. I expected this to happen because of the research I did.
Conclusion 
My hypothesis was that the container with grass in it would have less erosion than the one with out the grass. After doing my experiment I proved that my hypothesis was correct. From my research I learned that when you plant any kind of plant that has roots growing below the ground can help prevent erosion because the dirt gets caught in the roots and does not erode.

Overall I think that my experiment was a success not just because I proved my hypothesis was right,but also because I actually proved that there is a way to prevent erosion. I think I was accurate in doing my experiment. If I had more more time I could have shown how erosion effects land over a long period of time. Overall I think I had a well done project.
