| Name | Description |
| Soil Composition and Classification: | This unit builds on the previous lessons about rocks to explore soil. Different types of soil samples are observed, classified by various attributes, and manipulated by adding water. Finally, the "Cement" lesson involves synthesis of information learned from previous lessons in an engineering design lab that asks students to build a wall from their own mortar mixture creation that will withstand the force of a rolling ball. |
