The Scientific Method
The Scientific Method has 6 steps: ProblemResearchHypothesisExperimentData Conclusion

Step 1 - Problem/Question
You ask a question about what you observe.
![Page 5: The Scientific Method. - Way to solve a problem - Step by step plan - Tries to answer a question](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56649f315503460f94c4be85/html5/thumbnails/5.jpg)
Step 2 - Research
Gather information about the problem through observations, books, internet, or past experience. What do you know?
![Page 6: The Scientific Method. - Way to solve a problem - Step by step plan - Tries to answer a question](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56649f315503460f94c4be85/html5/thumbnails/6.jpg)
Step 3 - Hypothesis
•Prediction that can be tested by an experiment
•Answers the problem/question
•May be written in the form If …. then …..
![Page 7: The Scientific Method. - Way to solve a problem - Step by step plan - Tries to answer a question](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56649f315503460f94c4be85/html5/thumbnails/7.jpg)
Good Hypothesis
•Both an independent and dependent variable
•Declarative statement - NO I’s or We’s or My or Our
![Page 8: The Scientific Method. - Way to solve a problem - Step by step plan - Tries to answer a question](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56649f315503460f94c4be85/html5/thumbnails/8.jpg)
Step 4 - Experiment
• way to test the hypothesis and collect data under controlled conditions• The outcome must be measurable
![Page 9: The Scientific Method. - Way to solve a problem - Step by step plan - Tries to answer a question](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56649f315503460f94c4be85/html5/thumbnails/9.jpg)
Independent Variable:
- factor that is TESTED
- what is DIFFERENT between the groups
- what CHANGES between each set-up
THERE IS ONLY ONE INDEPENDENT
VARIABLE IN AN EXPERIMENT!!
![Page 10: The Scientific Method. - Way to solve a problem - Step by step plan - Tries to answer a question](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56649f315503460f94c4be85/html5/thumbnails/10.jpg)
Dependent variable:- what is MEASURED during the experiment
- affected by the independent variable
![Page 11: The Scientific Method. - Way to solve a problem - Step by step plan - Tries to answer a question](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56649f315503460f94c4be85/html5/thumbnails/11.jpg)
Constant Variables:
- variables that are kept the SAME
- makes the experiment FAIR
- there are MANY in an experiment
![Page 12: The Scientific Method. - Way to solve a problem - Step by step plan - Tries to answer a question](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56649f315503460f94c4be85/html5/thumbnails/12.jpg)
Experimental Group:
- the group that you are testing
- group that gets the factor you are testing
- group that gets the independent variable
![Page 13: The Scientific Method. - Way to solve a problem - Step by step plan - Tries to answer a question](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56649f315503460f94c4be85/html5/thumbnails/13.jpg)
Control Group:
- group that DOES NOT get the factor you are testing
- group that you check your results against
- used to compare results
![Page 14: The Scientific Method. - Way to solve a problem - Step by step plan - Tries to answer a question](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56649f315503460f94c4be85/html5/thumbnails/14.jpg)
Good Experiments
- large sample size- one factor tested (one independent variable)- quantitative or measurable results- Large sample size- Repeated for accuracy
![Page 15: The Scientific Method. - Way to solve a problem - Step by step plan - Tries to answer a question](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56649f315503460f94c4be85/html5/thumbnails/15.jpg)
Step 5 - Observations/Data
- Record any observations and data
![Page 16: The Scientific Method. - Way to solve a problem - Step by step plan - Tries to answer a question](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56649f315503460f94c4be85/html5/thumbnails/16.jpg)
Observations
Qualitative Observation - qualities (observable but not measurable)- no numbers- examples: color, shape, smell, texture
![Page 17: The Scientific Method. - Way to solve a problem - Step by step plan - Tries to answer a question](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56649f315503460f94c4be85/html5/thumbnails/17.jpg)
Observations
Quantitative Observations - quantities (observable AND measurable)- numbers- examples: length, volume, temperature

Graphs
Line Graph
-describes how one factor affects a second factor
-Continuous data
![Page 20: The Scientific Method. - Way to solve a problem - Step by step plan - Tries to answer a question](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56649f315503460f94c4be85/html5/thumbnails/20.jpg)
Graphs
Circle Graph- compares percentages- Compares part of a whole
![Page 21: The Scientific Method. - Way to solve a problem - Step by step plan - Tries to answer a question](https://reader035.vdocuments.mx/reader035/viewer/2022062422/56649f315503460f94c4be85/html5/thumbnails/21.jpg)
Graphs
Column or Bar Graph- used for comparison- discreet data points

Step 6 Conclusion
-accept or reject your hypothesis
-Support your answer with the data
-Publish your results
