Name ___________________________________ Glacial Simulation Lab Worksheet 1. You will see the glacial simulation lab in this window. https://phet.colorado.edu/sims/cheerpj/glaciers/latest/glaciers.html?simulation=gl aciers 2. Play with the sim for 5 minutes. Discuss 5 observations in complete sentences. (10 pts)
3. You can move tools around. You can place the tool back in the toolbox by placing it directly over the image. If you hover your mouse over the individual items in the toolbox, you will see the names of each item. 4. In science, we use the metric system. Please change your view to the metric system, and click equilibrium line. 5. Complete this chart to identify the tools in this simulation. (1 pt each=9 pts) Picture of Tool Name of Tool What is the tool used for? Thermometer Just for a Point of Reference Extraction of water or other liquids, geotechnical investigation, mineral exploration, etc.
6. Click “Reset all”. Each time you click “Reset all” you must change your view back metric system and click equilibrium line. 7. Allow the simulation to run for 20 years while keeping the climate with a sea- level air temperature of 19.0 ° C and 0.9 m.
8. Using the glacial budget meter, record the accumulation, ablation, and glacial budget at the equilibrium line. (3 pts) Accumuation Ablation Glacial Budget 9. What is the temperature at the same spot? (at the equilibrium line) (1 pt) 10. What is the glacial thickness at the equilibrium line? (1 pt) 11. What is the distance and elevation at the equilibrium line? (1 pt) 12. Change just the sea-level air temperature to 13.0 ° C. Use the bear at the top of your screen to locate the equilibrium line. Then, measure the distance and elevation at the equilibrium line. (2 pt)
