1. Environmental Science Chapter 1 Notes #1

2. Definitions Pure Science Ex. – Number of stars in solar system Ex. – Comparison of plant and animal cells Seeks to answer questions about how things work Applied Science Engineering, Medicine Solving problems/Technology

3. Definitions Environmental Science Applied Science Uses many different sciences chemistry, botany, zoology, meteorology Mainly ecology (how living things interact with other living and nonliving things) How humans interact with their environment

4. Scientific Method Systematic Approach to solving problems Many Steps 1. Problem/Purpose Ex. Bean Plant Experiment: You are testing a new fertilizer for a company to see if it is more effective at growing larger plants at a faster rate….. 2. Hypothesis Our background knowledge tells us it should be better

5. Scientific Method (2) Experiment: Materials: Procedure Control Constants Dependent Variable (Depends on independent) Independent Variable (you are in control)

6. Scientific Method (3) Observations/ Data Qualitative Quantitative Qualitative Vs. Quantitative Data Examples – pink, big, cold Examples – 20 books, 42 meters, 12 degrees Conclusion (analysis) What did you find Errors

7. Graphs – Part of Conclusion Circle, Bar and Line Percentages Comparison Growth/Change Graphs Need Size Labels, Titles
