1. Solar Radiation, Albedo, and Light Transmission in Seawater Objectives: To examine how the sun’s energy affects the ocean environment

2. The Earth’s revolution around the sun

3. Equinoxes and solstices

4. Exercise #1 – Solar Constant Set the equator to the same height as your light by using the meter stick Set the equator to the same height as your light by using the meter stick Measure using the Lux Meter Measure using the Lux Meter –Lux meters have different settings (x1, x10, x100) –Hold it flat to the globe for all readings

5. Sun’s rays and surface area

7. Exercise #2 – Latitude Latitude lines are parallel to the equator. Latitude lines are parallel to the equator. Keep Lux meter flat to the globe. Keep Lux meter flat to the globe. When answering your questions, be sure to move the globe and take new measurements. When answering your questions, be sure to move the globe and take new measurements.

10. Execise 3# - Albedo The incoming radiation will be the same for every sample. The incoming radiation will be the same for every sample. Do not move or change the set-up without asking the TA, only change out the sample trays. Do not move or change the set-up without asking the TA, only change out the sample trays. Ask the TA for an Ice sample to measure. Ice doesn’t have a dark sand bottom. Ask the TA for an Ice sample to measure. Ice doesn’t have a dark sand bottom.
