Last week, the class learned about the layers of the earth. The class made and labeled a diagram of the inside of the earth. The outer layer (crust) is very thin compared to the other layers. We will now focus on the crust of the earth and delve into our study of soil, minerals, and rocks.
This week...
Students will compare different types of soil (sand, silt, and clay) which are categorized by the size of their grains.
