Summary:
Soil erosion usually destroys things, like farms, and causes mudslides. There are many ways to prevent soil erosion. One way is to have plants dig into the soil instead of having trenches. Plants hold down the soil with their roots. Another way to reduce soil erosion is having low incline. That prevents the soil from running down a high incline and making more soil fall, causing soil erosion. Other ways to prevent soil erosion is having different types of soil. Silt, and Silt and Sand mixture reduces soil erosion.
SP8: Obtain, Evaluate, and Communicate Information:
This week, I obtained my data through an interactive with two different levels. The first level was trying to find out which kind of soil treatment (plant/trench), incline, and amount of water I needed to reduce soil erosion. The second level was basically the same, but with a new variable: soil type. This included sand, silt, or both mixed. I evaluated the validity of my answers by re-checking if each combination of variables were correct, then tested them. I communicated my information by putting my data on a sheet of paper provided, then, I communicated the best variables (soil treatment, incline, soil type, amount of water) needed to prevent soil erosion.
