Open up the PhET Glaciers simulation (http://phet.colorado.edu/en/simulation/glaciers) and play with the sim for five minutes (the simulator takes a long time to load). What do you find? Discuss your ideas.

3. Observe the different flow velocities using the coring machine and the flags. Where is the glacier flowing the fastest and the slowest? Suggest a reason for this difference

4. What claims can you make about the relationship between the amount of snowfall and the movement and thickness of glaciers? Provide evidence for your claims.

5. What claims can you make about the relationship between the average temperature and the movement and thickness of glaciers? Provide evidence for your claims.

6. Look at the rocky debris that the glacier is picking up and transporting. Where is the debris being deposited? What happens if the glacier stops for a while then retreats? What is left behind? What is this pile called? (You may need to look in the chapter for the correct term, or look it up on the internet)
