Hey Everyone-

Sorry, but I somehow missed where the powerpoint presentations were. I just started teaching earth science and would LOVE a copy!!!

Regards, Keely

First off, thank you, Monica, for posting your Power Point presentations. They will come in handy this year when I teach Earth science for the first time.
   
  Regarding session 4 and how to introduce plate tectonics to students so they may learn from observation, I have 2 ideas.
   
  1) Heat a pot of soup with crackers floating on top. Cover, or nearly cover the surface with the crackers. Observe the crackers move relative to one another as the soup heats and bubbles.
   
   
  2) Observe a pond with lily pads floating on it. Turn on the fountain or toss in a stone to see how the postions of the lily pads are affected.
   
  While these suggestions may simulate how the tectonic plates shift relative to one another, I am not sure what to suggest to represent the composition of the mantle.
   
  Any other ideas?
