What is a fossil? In this activity you read about fossils. Remember before reading, use the pre-‐reading strategy PAS. At the completion, answer the Aq’s in CSIQ.
• Below are few questions to think about before you read. • What is a fossil? • Give two examples of a body fossil? • Can a plant yield a trace fossil? Why or why not. • What are organic compounds made up of? • What are some ways that animals become fossilized?
Review and Reflect 1. What kind of plant and animal materials decompose most quickly? 2. What kind of plant and animal materials take the longest to decompose? 3. What is the difference between a body fossil and a trace fossil? 4. What kinds of materials from organisms have the best chance of becoming a fossil? Explain.
5. Sediments can often accumulate very quickly in places where rivers flow into the open ocean. Would this be a likely or unlikely place for fossils to form? Explain your answer.
