Question

Does potting soil affect how fast erosion happens?

Hypotheses

Zara thinks : I think the sand alone will have more erosion because the sand with potting soil might be very thick together.

Lacee and Angela think: We think the results won't be the same because the potting soil will be harder to erode and it will take longer.

Materials

The materials that we used are...

potting soil,sand, water ,bowl , two stream tables one cup with a big hole ,and a  ruler.

Our First  Setup

  1. Our first setup was potting soil and sand. The results were 1 minute and 59 seconds. The distance of soil was more in the potting soil and sand than the sand alone.

Our Second Setup

  1. Our second setup was sand alone. The results were 1 minute and 15 seconds.

Our conclusion

The answer to our question "Does the  potting  soil  affect how fast something erodes"is  yes, it does. We know this because when we ran water through potting soil an sand it took 1 minute and 59 seconds. When it was sand alone it took 1 minute and 15 seconds. So that proves  that potting soil can help sand withstand erosion!
