Build mounds of dirt forming as many valleys, creeks and spurs as you can.
Place the sticks upright in the soil where you want your ‘trees’ to be.
Pile leaves and twigs where you would expect them to be on your ‘hillside’.
Gently pour water over the entire site. Which areas lost more soil, why?
What could you do to fix the problems on the site? What if the soil was a different texture?

Why Does This Happen?
The top layer of soil contains a large amount of available nutrients for plants to use. These nutrients include inorganic minerals to those nutrients provided by rotting vegetation (humus). This layer of soil can be heavily eroded by the wind, rain and human impacts.
If this layer is lost, so is the available nutrients for plants to grow. In some parts of the world, top-soil erosion has become a major concern.
Variables to test
- Try using different types of soil. Do you lose topsoil as fast?
- Try experimenting with different ground covers (moss, woodchips, mulch, compost, leaf litter).
- If you slow the water running down the slope, does it reduce the erosion?
