3. Steps of the Scientific Method
1. Problem/Question: Develop a question or problem that can be solved through experimentation.

4. Steps of the Scientific Method
2. Research: Make observations and research your topic of interest.

5. Problem/Question/Research
Make an observation, which leads to asking a question, and then do research to learn more about the items/organisms you have observed.
Example:
Observation: You notice a plant has a lot of pine straw around its base. You also notice it is growing better than other plants of the same age and type. You know that pine straw makes the soil slightly acidic.
Question: Since orange juice is acidic, will it make plants grow at a faster rate also?
Research: Learn everything you can about orange juice and what conditions are needed to make a plant grow better.

6. Steps of the Scientific Method
3. Formulate a Hypothesis: (Educated Guess) Predict a possible answer to the problem or question.
**Always make your hypothesis an “If…then…” statement

7. Example of a hypothesis for our experiment…
If tomato plants are given orange juice daily, then they will grow better than plants that are not given orange juice daily.

8. Steps of the Scientific Method
Experiment: A set procedures to test a hypothesis under controlled conditions. You should always have a large sample size.
Involves two groups  control group & experimental group.

9. Constants (Controls)
The constants (controls) in an experiment are all the factors that the experimenter attempts to keep the same.

10. Experiment Continued….
Experimental Design:
1. Keep everything CONSTANT. Everything must stay the same except for the experimental variable (or treatment)
2. Dependent Variable –
On the Y axis
To determine, ask yourself
“What is being measured?”
3. Independent Variable –
On the X axis
“What am I changing?”

11. Experiment Continued ….
So let’s go over the experimental design for our “example” experiment…
Control Group?
Experimental Group?
Constants?
Dependent Variable?
Independent Variable?

12. Steps of the Scientific Method
5. Data and Data Analysis:
Collect your data in a neat format
Examples: Record your data in a chart/table and then show a visual representation of the data using a graph(s) – line, bar, pie, etc.
A. Quantitative Data – numbers
B. Qualitative Data – describes appearance

13. Line Graph
Independent Variable?
Dependent Variable?

14. Bar Graph
Independent Variable?
Dependent Variable?

15. Steps of the Scientific Method
R = Results. Overall outcome of study
E = Explanation. Explain results using scientific concepts. Includes IV, DV, and Control.
E = Evidence. Using data as proof accept or reject hypothesis
P = Possible Errors. Give an example of an error and the associated effect on your experiment.
6. Conclusion & Discussion: Include a statement that accepts or rejects the hypothesis and explain why.
REEP

16. Steps of the Scientific Method
7. Publish
Share the results of a study with other scientists
Publish findings in scientific journals or at scientific meetings/conferences

17. Think you can name all seven steps?

18. ARE WORM’S ALIVE?
Create a write up using the scientific method to prove to me that worms are alive.
No technology
Recommend textbook pages
Expectations:
Include every step of the scientific method
Every part of STERNGRR for the worm should be listed within your lab.
When finished have your group raise there hand and I will choose ONE lab to grade for the entire station.
