Study Notes
Definition of Science
- A system for acquiring knowledge through observation and experimentation.
- Uses knowledge application to improve societal conditions.
- Refers to both an organized body of knowledge and systematic study.
- Involves exploration of natural phenomena and creation.
Characteristics of Scientific Statements
- Must be falsifiable, allowing for potential disproval.
- Verifiability: Can the statement be proven false?
- Specificity: Clear means of verification stated.
- Credibility: Based on tentative truths or credible scientific sources.
The Scientific Method
- A systematic, step-by-step process for investigating natural occurrences.
- Key steps include:
- Observations
- Problem identification
- Hypothesis formulation
- Experimentation
- Result gathering and analysis
- Drawing conclusions
Controlled Experiments
- Aim to investigate cause-and-effect relationships by manipulating one variable at a time.
- Structure includes:
- Control setup: Baseline setup with no variable changes.
- Experimental setup: Similar to control but includes independent variable affecting the dependent variable.
- Running both setups allows for comparison and insight into variable effects.
Scientific Theories and Laws
-
Scientific Theory:
- Explanation based on extensive observations and investigations.
- Evolves from a hypothesis after numerous supporting data trials.
- Not permanent; subject to change with new evidence.
-
Scientific Law:
- Descriptive statement about consistent natural phenomena.
- Explains what happens under certain conditions but not why.
- Example: Law of gravity states that masses attract each other, while various theories explain the mechanism.
Limitations of Science
- Science does not address all questions or problems.
- Scientific questions must be testable and verifiable.
- Non-scientific questions involve opinions, values, and emotions and cannot be tested scientifically.
