1. Scientific Method

2. Steps Observation Hypothesis Experimentation
Collecting and Analyzing Data
Conclusion
Theory
Communication

3. Observation See something and question it
Create question or define problem based on what you see.

4. Hypothesis Educated guess Prediction about what will happen
Based on gathered research and observations
Prediction about what will happen
Often an “IF” “Then” statement
If you fertilize pea plants they will grow taller

5. Experimentation Design experiment to test hypothesis
Must be controlled experiment
Only 1 variable will change all other remain the same
Control group- standard, normal group
Experimental group- same as control except for 1 variable that has changed
Independent variable- the variable that is changed
Dependent variable- variable that is measured
It reacts to the independent variable

6. Collecting Data Qualitative data Quantitative data Organize data
Cannot be measured
Color, odor, shape, etc.
Quantitative data
Measured data
Organize data
Graphs
Charts
Tables

7. Conclusions
Hypotheses can only be disproven they cannot be proven by an experiment
Inferences made based on data collected in experiment
Can be used to build models of things

8. Theory Explains many related hypotheses
Highly tested generally accepted principal
Explains lots of data and observations

9. Communicating Publish papers
Explain experiment and results to others
Important for expanding scientific knowledge
