Rocks to eat?

The latest Earthlearningidea is 'Rocks to eat? How we get the elements we need to stay healthy'. Like all living things, we need many chemical elements in order to be healthy. These elements come from minerals in the soil and the soil gets the minerals from the rocks beneath. This activity explores how these elements reach us and other living things.
Do please let us have feedback on this activity.
