"We do not construct the world from our experiences; we are aware of the world in our experiences. Science is a language for talking not about experience but about the world."

You should be able to differentiate the description of stomatal densities from your explanation of the relationship between rainfall and stomatal densities. Is there a causes and effect relationship between stomatal densities and the rainfall between January 1st and September 1st? How can you convince others of this relationship, based on evidence you have developed and on logical argument. Think critically about evidence and decide what evidence should be used and accounting for anything unusal. The more lines of evidence you have to support your conclusion, the stronger your case is. This experiment was set up to test a hypothesis.

H0: There is no measurable relationship between annunal rainfall between January 1st and September 1st and stomatal densities occuring on the leaves of cottonwood tree (Populus deltoides).
H1: There is a measurable relationship between annunal rainfall between January 1st and September 1st and stomatal densities occuring on the leaves of cottonwood tree (Populus deltoides).

What can you say about these two alternative explainations of what goes on in the natural world? Did you test them? What else can you include to support your explaination.

As you have thought about your information, you may have come up with some conclusions related to the stomatal densities and/or the research question in this research activity. Your conclusion should be added to this list of conclusion papers. You add your conclusion and your comments below.
