What is science? Organized way of using evidence to learn about the natural world. Also the body of knowledge scientists have built up after years of using this process.
What is the Scientific Method? A sequence of logical steps to help form new ideas, answer questions, and draw conclusions.
Scientific Method Observations/Questions Hypothesis Testing/Experiments Analyze Results Conclusion
1. Observation: Things you notice or the gathering of information (data). Quantitative: Expressed as numbers Qualitative: Descriptive and involve characteristics that can’t be counted.
2. Hypothesis: a proposed scientific explanation. An “Educated guess” A statement about what you think will happen. It is usually written as a prediction
Example: If: I add a paper clip to my rotocopter Then: It will stay in the air longer Must be proposed in a way that it can be tested.
3. Testing/Experiments: Hypothesis must be tested. A. Gather more data B. Controlled experiments
What is a controlled experiment? An experiment in which all variables are controlled or stay the same with only 1 variable changed.
Variable: Factor in an experiment that can be changed Independent (Manipulated) variable: A variable that is deliberately changed. (Thing being tested)
Dependent (Responding) variable: One that changes in response to the independent variable. (Thing being measured) Controlled variables: Factors in the experiment that are kept the same.
Control Group: The group which receives no treatment and serves as the “norm” Flower A Flower B
Flower B Flower A
4. Analyze Results: Record and study data. 5. Conclusion: Was the hypothesis supported or refuted?
