The hypothesis is that the container with just soil will displace the greatest amount of soil when the same amount of water is poured on to each one.

You will measure the amount of soil displaced when the same amount of water is poured onto two different containers - one with grass and soil, and one with just soil.

You will need bins containing soil, water, graduated cylinders, 5 trays (1 tray with grass growing in soil, 2 with just soil, 2 empty), a ruler, paper towels, rubber bands, a text book, rain forest journals, and an overhead projector.

The results showed that high amounts of soil were displaced in the container that just contained soil. This experiment demonstrates that soil erosion occurs when unprotected soil is washed away by rainfall, and that plants prevent soil erosion by stabilizing the soil with their root systems.

This science project is interesting and unique because it allows students to observe the effects of soil erosion on the destruction of rain forests in a hands-on way.

Experiment variations to consider include tilting both trays with their science books so that one end is higher than the other, and stretching a paper towel around the tops of the empty containers to filter the water from the dirt as it is displaced.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
