3. Ablation Run #1: Collect ‘baseline’ measurement. Release your glacier (goo). Time and observe for 2
minutes then stop and hold to measure. Record findings. Complete this section of the chart.
4. Steady Run #2: Collect ‘baseline’ measurement. As the glacier flows add small bits of your remaining
glacier (goo) to the glacier surface as ‘new snow’ every 20 seconds for 2 minutes. Measure and record
your glacier and complete the chart. Compare elevation results in run #2 to run #1.

5. Ice Shelf Run #3. What if the ice shelf in front of your glacier were to melt from warming ocean
water? Collect ‘baseline’ measurement. Place your ruler in front of the glacier as a shelf and hold it in
place for 1 minute. Ice may flow over it but keep your shelf in place. After 1 minute remove your ice
shelf (ruler) and observe 1 minute. Measure and record your glacier. Complete chart.
6. Compare to Your Hypothesis: Write a sentence explaining if the overall behavior of this model glacier
supports your hypothesis._____________________________________________________

7. Additional Data: What other data would be useful to further test your hypothesis, or a revised or new
hypothesis? ___________________________________________________________________
8. Match to the Real World: Glacier goo is not the same as a real glacier but it can help us learn about
real glaciers. Note 2 things you have learned about P.I.G. working with your own glacier model & be
sure at least one mentions a connection to climate.

9. Design your own run: Design your own experiment using glacier goo. Describe the conditions
and the results. Be sure to note how it relates to a real glacier. ________________
