(1) scientific method

the steps of the scientific method

1. make an obersvation

2. form a hypothesis

3. make a prediction

4. preform an experiment

5. gather data

6. analyze findings

7. draw a conclusion

falsiability

hypothesis must be falsifiable; if they are not true, they can be determined to be false

testing a hypothesis

factors:

• independent variable: the experimental variable that changes

• dependent variable: how the variable reacts to that change

• null hypothesis: the default hypothesis

• alternative hypothesis: the hypothesis that counters the null hypothesis

interpolation vs extrapolation

interpolation: between measured points on a graph

extrapolation: goes beyond the experience with an experiment
