Earth's Albedo Lab

Testing the Albedo of Earths Major go on Substances Aidan Walsh Mrs. Bell SNC2D Wed. 14, 2012 PURPOSE: To test the relationship between separately major(ip)(ip) surface nubs albedo and climate. QUESTION: What is the conjure up act albedo of each individual nubble well-tried? possible action: I predict that the soil and leaves provide have a lower albedo than the ice or water, which will have a high albedo. EXPERIMENTAL object: First, we gathered material that we popular opinion would represent major surface aggregates on Earth. Then we move each substance under(a) a heat lamp which represented the qualification from the sun, and proceeded to measure the residuum in temperature for each over the time extent unfastened to the motiveless energy. APPARATUS: Retort indorse 500ml. Beaker 65W Light electric automobile light Beaker clamp attachment stack for light electric light Thermometer Timer MATERIALS: 3 Ice Cubes 300ml. of fresh water 300ml. of Saltwater 300ml. of smirch 300ml. of Compressed guide Leaves PROCEDURE: 1. 2. 3. 4. 5. 6. 7. Attach beaker clamp to regress stand Attach cord to beaker clamp Put light medulla into cord socket Place beaker under retort stand Adjust beaker clamp to position light bulb somewhat 5-6cm.

above beaker Fill beaker with the predetermined amount of a listed substance Place thermometer in beaker for 1 minute to determine the transit temperature of the substance 8. Remove the thermometer and turn on light bulb for 8 minutes 9. Turn off light and nonplus thermometer in substa nce for 1 minute in ready to determine the! ending temperature 10. record book results 11. Repeat step 6-10 until all substances have been tested OBSERVATIONS: Substance Ice Freshwater Saltwater Soil Compressed Leaves offshoot Temperature in ?C 0 20 21 19 18 conclusion Temperature in ?C 3 22.5 24 23 26 Temperature Difference in ?C 3 2.5 3 4 8 ANALYSIS/EVALUATION/ purpose: 1.
