1. Relative density, heat capacity, coriolis effect, convection in the atmosphere Objectives: to understand –heat capacity of rocks and water –what drives atmospheric circulation –effect of coriolis deflection Dimensional analysis units dimensions significant figures

3. water dark tan soil sand Which material heats up faster? Cools down faster? Experiment 1 Heat capacity Data table Record temperature Every minute Sun ON 10 minutes Sun OFF 10 minutes Graph results

4. Water and dry ice Experiment 2 Relative density of air put column over dry ice observe direction of vapor flow remove column observe the direction of vapor flow record data Temperature inside beaker? Temperature outside column? Wear glove to handle dry ice!!!

5. Water and dry ice Experiment 3 Coriolis effect put beaker on lazy suzan put column over dry ice note location of marker on lazy suzan surface spin slowly observe direction of vapor flow relative to marker Wear glove to handle dry ice!!! spin slowly

6. Is direction of vapor flow in your beaker experiment more like or Why? Cite observations from experiment to justify answer Group 1

7. Group 2 If Is direction of vapor flow steam similar to or Why? Cite observations from these experiments or prior experiments to justify answer

8. Group 3 Describe the atmospheric circulation during northern summer (July August) Why? Cite observations from experiment to justify answer

9. Group 4 Describe the atmospheric circulation during northern winter (January February) Why? Cite observations from experiment to justify answer

10. Group 5 What time of year would be best for climbing Mt. Everest? Why? Cite observations from experiment to justify answer
