8th Grade Life Science

Natural Selection

1. Many thousands of layers of sedimentary rock provide evidence for the long history of the earth and for the long history of changing life forms whose remains are found in the rocks. More recently deposited rock layers are more likely to contain fossils resembling existing species. (AKSci - A.13)

Examples of What Students Should Be Able to Do:

• Draw/create a model of a cross section of sedimentary rock layers and place 5 fossils appropriately on the model.
