11
Experiment should be controlled
experimental group control group Should have a good sample size;

Controlled experiments contain:
Independent variable Dependent variable Standardized/controlled variable
13
How to evaluate science in the media
Consider the source Consider the expert Consider the funding Is the report free of bias? Is it balanced?
14
So, environmental science then, is. . .
The interdisciplinary study of so that

At the end of the day, what does this scientific process give us?
Outcome 1: New/altered theories Outcome 2: A paradigm shift Outcome 3: More questions & problems Outcome 4:
