Study Notes
Definition of Science
- Systematic study of the structure and behavior of the physical and natural world.
- Involves observation, experimentation, and theorization.
Branches of Science
-
Natural Sciences
- Focus on the natural world.
- Includes Physics, Chemistry, Biology, Earth Science.
-
Formal Sciences
- Study abstract concepts.
- Includes Mathematics, Logic, Statistics.
-
Social Sciences
- Study human behavior and societies.
- Includes Psychology, Sociology, Anthropology, Economics.
-
Applied Sciences
- Practical application of scientific knowledge.
- Includes Engineering, Medicine, Environmental Science.
Scientific Method
-
Observation
- Gathering data and noticing phenomena.
-
Hypothesis Formation
- Proposing explanations based on observations.
-
Experimentation
- Testing hypotheses through controlled experiments.
-
Analysis
- Interpreting data and results.
-
Conclusion
- Drawing conclusions based on analysis; may support or refute the hypothesis.
-
Peer Review
- Subjecting research to the evaluation of other experts in the field.
Key Concepts
-
Theory vs. Law
- Theory: Explanation of phenomena based on extensive evidence (e.g., Theory of Evolution).
- Law: Statement based on repeated experimental observations (e.g., Laws of Motion).
-
Variables in Experiments
- Independent Variable: The factor manipulated by the researcher.
- Dependent Variable: The factor measured in response to changes in the independent variable.
- Control Variables: Factors kept constant to ensure a fair test.
Importance of Science
- Drives technological advancement and innovation.
- Informs public policy and decision-making.
- Enhances understanding of the universe and human existence.
Ethical Considerations
- Importance of ethical conduct in research (e.g., informed consent, animal welfare).
- The impact of scientific advancements on society and the environment.

Scientific Method
- Observation: Involves gathering data and noticing phenomena in a structured manner.
- Hypothesis Formation: Proposes explanations based on initial observations.
- Experimentation: Conducts controlled experiments to test the validity of hypotheses.
- Analysis: Involves interpreting data collected from experiments to draw meaningful results.
- Conclusion: Conclusion drawn can support or refute the original hypothesis based on the analysis.
- Peer Review: Essential for maintaining scientific integrity by subjecting research to evaluation by experts in the field.
Key Concepts
-
Theory vs. Law:
- A theory is an explanatory framework built on extensive evidence (e.g., Theory of Evolution).
- A law is a statement derived from repeated experimental observations (e.g., Laws of Motion).
-
Variables in Experiments:
- Independent Variable: The manipulated factor by the researcher.
- Dependent Variable: The measured factor that responds to changes in the independent variable.
- Control Variables: Constants maintained to ensure the experiment is fair and valid.
Importance of Science
- Science serves as a driving force for technological advancement and innovation.
- It informs public policy decisions and enhances knowledge of the universe and human existence.
Ethical Considerations
- Ethical conduct in research is critical, encompassing aspects such as informed consent and animal welfare.
- Scientific advancements have significant implications for society and the environment, necessitating careful consideration of their impact.
