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.
