  3. 3. How much evidence do we need in science?<br />Avoiding De-Natured Science by Lederman<br />
  4. 4. How can we trust science if it is changing?<br />
  5. 5. What in the world happened here?<br />
  6. 6. What is Science?<br />No magic, gremlins or other supernatural explanations needed!<br />Science assumes that the natural world can be understood by gathering evidence. <br />Science attempts to explain the natural world and these explanations are tested using evidence.<br />
  7. 7. Perhaps a natural explanation is that the continents used to be arranged differently in the past<br />Can you fit them together in order to make sense of the evidence?<br />What in the world happened here?<br />
