Study Notes
The Investigatory Process and Scientific Method
- The scientific method consists of a series of steps that scientists use to differentiate facts from myths or speculations.
- Key objectives include describing scientific investigation components, conducting experiments for community problems, and understanding persistence in problem-solving.
Observation
- First step involves making an observation about something intriguing.
- Observations should inspire questions to further exploration.
Questioning/Statement of the Problem
- After observation, formulate a specific question to define what you seek to discover.
- Specificity in questioning enhances the clarity of the experiment’s goal.
Hypothesis
- A hypothesis is a proposed explanation for an observation, which can be tested through experimentation.
- It should be formulated in a way that allows for measurable outcomes.
Experiment
- Designing an experiment involves establishing a procedure to test the hypothesis.
- Identify independent (changed) and dependent (measured) variables, alongside controlled variables to maintain consistency.
Results
- Report the observations and data from the experiment, often through charts or graphs for clarity.
- Results provide insights into the experimental outcomes and validation of the hypothesis.
Conclusion
- The final step involves analyzing experiment results and determining if they support or reject the hypothesis.
- If the hypothesis is not supported, revisions to the procedure or further experimentation may be required.
Identifying Variables
- Three key types of variables in experimentation:
- Independent Variable: The factor that is changed or manipulated.
- Dependent Variable: The factor that is measured or observed.
- Controlled Variable: Constant factors to minimize their effects on the experiment.
Examples of Scientific Method Applications
- Example scenario: Observing flooding in a village and hypothesizing that garbage in the river contributes to the issue.
- Designing an experiment to gather data on the impact of littering on flood levels would illustrate the steps of the scientific method in real-life applications.
Historical Perspective
- Sir Isaac Newton illustrates perseverance in science, conducting over 200 experiments to decipher light and color.
- His journey underscores the importance of persistence in achieving success and understanding complex concepts in science.
