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?

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.
