This visual example of erosion would help students understand how human activities can affect the landscape. One bottle could represent an untouched forest, another could represent an area with houses built, and another bottle could show land cleared for farming. The students would be able to see how humans can negatively impact Earth's natural processes.

Apples and Handwashing: "We put a clean apple slice in one jar. We passed another apple slice around the class as we came in from recess with dirty hands. We have been observing the two jars in the science center. This is the difference after 8 days - gross! (This picture doesn't really show the mold.)" - A great way to teach about germs.
