Study Notes
- Environmental Science studies the interaction of humans with the natural environment
- Science is both a collection of knowledge and a process used to learn information
- Science uses facts as evidence
- Science is adaptive, self-reflective, and iterative
- Science is a shared endeavor
Scientific Method:
- Quantitative vs. Qualitative observations are different, and:
- Quantitative data is a number/numerical
- Qualitative data is a category/categorial
Characteristics of a Good Question:
- A good question is not simply answered or obvious
- Facts, not opinions, should be employed
- Independently verifiable
- Worth knowing
- Testable
Hypothesis Testing
- Science tries to reject the null hypothesis (alternative hypothesis).
- Hypothesis must be tentative and testable explanation.
- Must be falsifiable. Prove what scientists think can't be proven
Experiment
- A procedure carried out to refute or confirm a hypothesis
- Provides insight into cause-and-effect relationships.
