  • Science says is a hand motion game. When science says intrusion, take your hand and push it up into the air like you were magma pushing through rock.
  • After introducing index fossils, ask students which fossils could be index fossils in this diagram (2, 5, 3). Say, well if we know that fossil 2 is 50 million years old, what do we know about the layer it is in? If we know that fossil 5 is 25 million years old, what do we know about the age of the layer it is in?
  • Transcript of "9/29/11"

    1. 1. 9/30/11 B DayLEQ: How do rocks, fossils, and ice cores help us paint a picture of Earth’s history? <br />1. Give one example of absolute dating.<br />2. Give one example of relative dating.<br />3. What is the law of superposition?<br />4. What is the difference between the lithosphere and the asthenosphere?<br />5. What causes tectonic plates to move and shift?<br />
    2. 2. Review and Quiz<br />Convergent<br />Divergent <br />Transform<br />Subduction<br />Mid-Ocean Ridge<br />Seafloor spreading<br />Trench<br />Rift Valley <br />BRAIN POP: plate tectonics<br />
    3. 3. Once you finish…<br />Read the article provided<br />2. In your notebook, draw a picture or diagram to illustrate a part of the article you read<br />3. If you finish early, jot down what you know about global warming and make a list of things you wonder about or would like to learn<br />
    4. 4. Today’s LEQ: How do rocks, fossils, and ice cores help us paint a picture of Earth’s history? <br />By the end of today, you should be able to…<br />Identify index fossils and intrusions<br />Explain how tree rings and ice cores can tell us about the past<br />
