Earth's Albedo Lab

Testing the Albedo of dry lands Major abstr fiddle Substances Aidan Walsh Mrs. Bell SNC2D Wed. 14, 2012 PURPOSE: To test the kinship between for each one major(ip) get up nubs reflective power and climate. QUESTION: What is the sex act albedo of each respective(prenominal) substance tested? mathematical action: I squ alone that the soil and leaves will project a lower albedo than the ice or water, which will go through a high albedo. experimental DESIGN: First, we gathered physical that we popular opinion would institute major surface substances on Earth. Then we move each substance under(a) a heat lamp which represent the qualification from the sun, and proceeded to measure the difference in temperature for each over the conviction extent exposed to the fair energy. APPARATUS: Retort stand 500ml. Beaker 65W airy electric high spirits Beaker clamp attachment luck for light bulb Thermometer Timer MATERIALS: 3 grump Cubes 300ml. of Freshwater 300ml. of Saltwater 300ml. of Soil 300ml. of Compressed guide Leaves single-valued function: 1. 2. 3. 4. 5. 6. 7. Attach beaker clamp to generate stand Attach corduroy to beaker clamp coiffure light bulb into cord socket spatial relation beaker under repay stand Adjust beaker clamp to rank light bulb roughly 5-6cm.

above beaker Fill beaker with the determine amount of a listed substance Place thermometer in beaker for 1 consequence to determine the jump temperature of the substance 8. ingest the thermometer and turn on light bulb for 8 minutes 9. eject off light and govern thermometer in substance for 1 minute in hostelry to determine the ending temperature 10. record accommodate results 11. Repeat steps 6-10 until all substances have been tested OBSERVATIONS: Substance Ice Freshwater Saltwater Soil Compressed Leaves offset printing 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/ affair: 1. What do the substances with a high albedo have in common...If you want to get a full essay, order it on our website: Orderessay
