Class Notes Unit 2 – Scientific Research Hypothesis:
10
Class Notes Unit 2 – Scientific Research Hypothesis: 1. Written as “yes or no” question
11
Class Notes Unit 2 – Scientific Research Hypothesis: 1. Written as “yes or no” question 2. Always before experiment
12
Class Notes Unit 2 – Scientific Research Hypothesis: 1. Written as “yes or no” question 2. Always before experiment 3. Does the data SUPPORT or disprove hypothesis?
13
Class Notes Unit 2 – Scientific Research Hypothesis: 1. Written as “yes or no” question 2. Always before experiment 3. Does the data SUPPORT or disprove hypothesis? Example: Can a plant be given too much water?

Class Notes Unit 2 – Scientific Research Purpose of the Scientific Method:
15
Class Notes Unit 2 – Scientific Research Purpose of the Scientific Method: 1. Information is useful
16
Class Notes Unit 2 – Scientific Research Purpose of the Scientific Method: 1. Information is useful 2. Information can be shared
17
Class Notes Unit 2 – Scientific Research Purpose of the Scientific Method: 1. Information is useful 2. Information can be shared 3. Experiments can be replicated
18
Class Notes Unit 2 – Scientific Research Levels of Support in Science:
19
Class Notes Unit 2 – Scientific Research Levels of Support in Science: nothing in science is ever PROVEN
20
Class Notes Unit 2 – Scientific Research Levels of Support in Science: nothing in science is ever PROVEN 1. Hypothesis: before an experiment – limited support
21
Class Notes Unit 2 – Scientific Research Levels of Support in Science: nothing in science is ever PROVEN 1. Hypothesis: before an experiment – limited support 2. Theory: after MANY experiments – well supported idea

Class Notes Unit 2 – Scientific Research Sampling:
26
Class Notes Unit 2 – Scientific Research Sampling: 1. almost impossible to examine EVERYTHING
27
Class Notes Unit 2 – Scientific Research Sampling: 1. almost impossible to examine EVERYTHING 2. a sample is a representative group
28
Class Notes Unit 2 – Scientific Research Sampling: 1. almost impossible to examine EVERYTHING 2. a sample is a representative group Example: 100 elephants = 5 in each of 20 regions
