1. Scientific Method A planned approach to solving a problem
Make Observations and form a hypothesis
Test Hypothesis/Perform Experiment
Define/Identify the Problem
Organize and Analyze Data
New Experiment
Do Experiment and Observations Support Hypothesis? No
Draw Conclusion
Communicate Results
Yes
Faulty Experiment?
A planned approach to solving a problem

2. Problem
A well-defined question

3. Anything you see, hear, taste, touch, or smell
Observation
Anything you see, hear, taste, touch, or smell
(using your senses)

4. Implying a conclusion based on observations
Inference
Implying a conclusion based on observations

5. Hypothesis
An educated guess

6. Experiment
A test of the hypothesis

7. Procedure
The step by step plan for the experiment

8. Variable = Size of the Ball
Anything that changes during the experiment
2 Types: Independent & Dependent
Variable = Size of the Ball

9. Independent Variable The variable that YOU change in the experiment
50 mL water
100 mL water
200 mL water

10. Dependent Variable
The variable that responds to the independent variable
What changes because YOU changed something =
Height of Plant
(affects)
50 mL mL mL

11. Same size/color/type of flower
Control/Constant
The factors that are kept or stay the same in the experiment
Same amount of soil
Same size/color/type of flower
Same amount of light

12. Collect & Analyze Data Information collected from the experiment
Usually displayed in the form of a chart, table, or graph

13. Conclusion
Forming an answer based on the interpretation and analysis of data

14. Classify
To sort objects and/or organisms into categories

15. Model
A structure that visually represents real events or objects

16. Models cannot show us everything about what they represent
Limitation
Models cannot show us everything about what they represent
