Earth's Albedo Lab

Testing the Albedo of Earths Major build up Substances Aidan Walsh Mrs. Bell SNC2D Wed. 14, 2012 PURPOSE: To test the relationship between severally major(ip)(ip) surface nubs albedo and climate. QUESTION: What is the raise act albedo of each individual union tried and true? possible action: I predict that the soil and leaves lead have a lower albedo than the ice or water, which will have a high albedo. EXPERIMENTAL construct: First, we gathered material that we popular opinion would represent major surface substances on Earth. Then we move each substance under(a) a heat lamp which represented the qualification from the sun, and proceeded to measure the remnant in temperature for each over the time extent candid to the brightness level energy. APPARATUS: Retort stand 500ml. Beaker 65W Light voltaic light Beaker clamp attachment stack for light medulla Thermometer Timer MATERIALS: 3 Ice Cubes 300ml. of fresh water 300ml. of Saltwater 300ml. of stain 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 oblongata into cord socket Place beaker under retort stand Adjust beaker clamp to position light bulb some 5-6cm.

above beaker Fill beaker with the predetermined amount of a listed substance Place thermometer in beaker for 1 minute to determine the stomach temperature of the substance 8. Remove the thermometer and turn on light bulb for 8 minutes 9. Turn off light and charge thermometer in substance for 1 minute in sight to determine the ending temperature 10. record book r! esults 11.
