Lake Stevens Sr High School HEC 34 0Lab: Absorption and Radiation by Land and Water

Document Content and Description Below

The lab was about absorption and radiation by land and water. With showing temp changes with lights on the type of material. I predicted the material will heat up i was correct because it absorbed a... nd got hotter. The lab was taking a light and putting it on a material for 15 minutes and measure the temp.

This is very logical because when you put heat on anything it tends to get hotter and absorb the heat. This could of been improved by not being confusing this lab was super confusing and i don't know the purpose of the lab really. The purpose of the lab is to show how different material absorb heat. By using light on it for 15 minutes and record every 3 minutes. My hypothesis for this lab was the material will get increase in heat because you're shining a light on it. was [Show More]
