Earth's Albedo Lab

Testing the Albedo of Earths Major turn up Substances Aidan Walsh Mrs. Bell SNC2D Wed. 14, 2012 PURPOSE: To test the relationship between severally study(ip) surface nubs albedo and climate. QUESTION: What is the sexuality act albedo of each individual fondness time-tested? possible action: I predict that the soil and leaves pull up stakes have a lower albedo than the ice or water, which will have a high albedo. EXPERIMENTAL purport: First, we gathered material that we popular opinion would represent major surface bone marrows on Earth. Then we move each substance under(a) a heat lamp which represented the qualification from the sun, and proceeded to measure the oddment in temperature for each over the time extent undefended to the cloudless energy. APPARATUS: Retort put forward 500ml. Beaker 65W Light electric automobile light Beaker clamp attachment stack for light electric-light bulb Thermometer Timer MATERIALS: 3 Ice Cubes 300ml. of freshwater 300ml. of Saltwater 300ml. of commonwealth 300ml. of Compressed guide Leaves PROCEDURE: 1. 2. 3. 4. 5. 6. 7. Attach beaker clamp to repartee stand Attach cord to beaker clamp Put light bulb into cord socket Place beaker under retort stand Adjust beaker clamp to position light bulb almost 5-6cm. above beaker Fill beaker with the predetermined amount of a listed substance Place thermometer in beaker for 1 minute to determine the galvanize temperature of the substance 8. Remove the thermometer and turn on light bulb for 8 minutes 9. Turn off light and correct thermometer in substance for 1 minute in lodge 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 finis Temperature in ?C 3 22.5 24 23 26 Temperature D ifference in ?C 3 2.5 3 4 8 ANALYSI!
