1.	Briefly research global dimming and global shading as both a solution to global warming and as an effect of air pollution. Identify your information source. (8 points)		
2.	 Set-up and conduct your experiment to determine how shading or filtering light, impacts evaporation over a fixed time period.  (8 points)		
3.	Predict the impact of global shading or dimming, and global warming over the next 100 years. (4 points)
		
4.	At least one reliable resource (required) 
(4 points)
		
5.	When you have completed your paper, submit it to the Altering Natural Systems Drop box.

Criteria and Constraints:

•	At least one reliable resource (required)
•	Set up your experiment to include at least one control container of water, and one or more experimental containers with differing levels of shading.
•	Use your data and data gathered from research to support your opinion or prediction on the impact of these phenomenon on climate over the next 100 years.  
•	Your combined research and data paper should not be more than two (2) pages.
