  3. 3. FOSSILS <ul><li>What are fossils? </li></ul><ul><li>How do fossils form? </li></ul>
  4. 4. FOSSILS <ul><li>You have 4 minutes to copy and answer Questions </li></ul><ul><li>What are fossils? </li></ul><ul><li>What evidence can we get from fossils? </li></ul>
  5. 5. You have 3 minutes to copy and complete task into your science book <ul><li>Fossils (from Latin fossus, literally &quot;having been … …&quot;) are the …….remains or traces of animals and …… buried in the ground …… of …..ago. </li></ul><ul><li>Dug up </li></ul><ul><li>Thousands </li></ul><ul><li>Years </li></ul><ul><li>Plants </li></ul><ul><li>Preserved </li></ul>
  6. 6. <ul><li>Fossils (from Latin fossus, literally &quot;having been dug up&quot;) are the preserved remains or traces of animals and plants buried in the ground thousands of years ago. </li></ul>
  7. 7. <ul><li>Fossils (from Latin fossus, literally &quot;having been dug up&quot;) are the preserved remains or traces of animals and plants buried in the ground thousands of years ago. </li></ul>
  8. 8. EVIDENCE FROM FOSSILS <ul><li>To review different types of fossil and how they were formed. </li></ul>
  9. 9. PREHISTORIC LIFE <ul><li>You will understand how plant and animal remains can be fossilised and how this allows understanding of prehistoric plant and animal life. </li></ul>
  10. 10. WEATHERING - WEARING AWAY Discuss how large rocks can be broken by natural forces called weathering. Look at samples of sand and identify that it is made of small mineral particles
  11. 11. WRITING A LETTER <ul><li>Homework </li></ul><ul><li>Write a letter to a friend explaining how the remains of plants and animals can be fossilised and how it can help us to understand prehistoric plant and animal life. </li></ul><ul><li>Due date: 13 th June 2011 </li></ul><ul><li>Note: Your letter will be read in class as part of your assessment. </li></ul>More resources please visit: www.sciencetutors.zoomshare.com
  12. 12. <ul><li>To model fossil formation by casting from an impression. </li></ul>
  13. 13. WEATHERING - WEARING AWAY Briefly explain how acid rain is formed. Use diagram to reinforce your explanation
  14. 14. Erosion And Sedimentation of Rocks <ul><li>Look at the pebbles and discuss why they are smooth and round- relate your answer to the wearing action of moving water and rocks rubbing together. </li></ul>
  15. 15. <ul><li>The term ' acid rain ' means any form of precipitation like rain, fog, snow, or hail that contains harmful substances such as nitrogen and sulphur oxides. ... </li></ul>
