How does the surface of an object affect the amount of radiation is reflects/absorbs?  In order to answer this question the following materials will be used: soil white sand water crushed ice stryofoam gravel light sources thermometers stopwatch

Procedure: 1. Fill 6 beakers with each material at the same level. 2. Place thermometer in each beaker. 3. Record starting temperature for each container. 4. Place each beaker under a light source. Light source should be same distance above each beaker. 5. Record temperature in each beaker every minute for 15 minutes. 6. Turn off light source. 7. Record temperature in each beaker every minute for 15 minutes. 8. Graph results. 9. Determine how each surface absorbed heat and released heat. 10. Reach conclusion.
