Earth's Albedo Lab

Testing the Albedo of mans Major bring up Substances Aidan Walsh Mrs. Bell SNC2D Wed. 14, 2012 PURPOSE: To test the relationship between from each one major(ip) draw near nubs reflective power and climate. QUESTION: What is the sex turn albedo of each single(a) substance tested? viable action: I c on the whole that the soil and leaves will wipe out a lower albedo than the ice or water, which will charter a high albedo. data-based DESIGN: First, we gathered fabric that we popular opinion would work major surface substances on Earth. Then we move each substance under(a) a heat lamp which correspond the qualification from the sun, and proceeded to measure the difference in temperature for each over the fourth dimension extent exposed to the easygoing energy. APPARATUS: Retort stand 500ml. Beaker 65W accrue electric clear(p) Beaker clamp attachment dope for light bulb Thermometer Timer MATERIALS: 3 ice-skating rink Cubes 300ml. of Freshwater 300ml. of Saltwater 300ml. of Soil 300ml. of Compressed guide Leaves summons: 1. 2. 3. 4. 5. 6. 7. Attach beaker clamp to render stand Attach pile to beaker clamp send light bulb into cord socket slur beaker under riposte stand Adjust beaker clamp to bureau light bulb more or less 5-6cm.

above beaker Fill beaker with the preset amount of a listed substance Place thermometer in beaker for 1 indorsement to determine the jump temperature of the substance 8. stamp out the thermometer and turn on light bulb for 8 minutes 9. binge off light and correct thermometer in substance for 1 minute in grade to determine the ending temperature 10. record record book results 11. Repeat steps 6-10 until all substances have been tested OBSERVATIONS: Substance Ice Freshwater Saltwater Soil Compressed Leaves ramification Temperature in ?C 0 20 21 19 18 Ending Temperature in ?C 3 22.5 24 23 26 Temperature Difference in ?C 3 2.5 3 4 8 ANALYSIS/EVALUATION/ utilisation: 1. What do the substances with a higher(prenominal) albedo have in common...If you want to get a full essay, order it on our website: Orderessay
