Friday—Lab pg 322 “Finding Clues to Rock Layers” Objectives: 1. Interpret data from the various fossils found in rock layers. 2. Draw conclusions about the relative ages of rock layers.

Science Standards for Chapter 10 1. Interpret laws of superposition of rocks and how it relates to Earth’s age and history. 2. Describe how Earth’s features are changing constantly by slow and fast processes such as erosion, weathering, deposition, landslides, volcanic eruptions and earthquakes. 3. Recognize constructive and destructive forces that affect Earth’s history. 4. Use appropriate math and technology to gather and store and organize data. a. Radioactive dating 5. Use scientific models and describe how smaller experiments in the lab relate to larger real world systems.
