Stopping Soil Erosion
Hard
In this experiment, we'll measure the effects of polyacrylamide and polyacrylate on soil erosion. We'll measure the amount of erosion in each tray and compare the results.
Hypothesis
The hypothesis is that polyacrylate will be the most effective at halting erosion.
Method & Materials
You will fill eleven trays with dirt, measure out polyacrylamide and polyacrylate, spread it out evenly, and then run water through the trays for five days.
You will need eleven trays, 227.25 grams of dirt, polyacrylamide, and polyacrylate.
Results
The results showed that polyacrylate was the most effective at halting erosion. The tray with no polymers had the most erosion.
Why do this project?
This science project is interesting because it shows how polymers can be used to halt soil erosion.
Also Consider
Variations to consider include using different amounts of polymers or different types of soil.
