Study Notes
Definition of Science
- Systematic study of the natural world.
- Involves observation, experimentation, and analysis.
Branches of Science
-
Natural Sciences
- Study of natural phenomena.
- Divided into:
- Physics: Study of matter and energy.
- Chemistry: Study of substances and their interactions.
- Biology: Study of living organisms.
-
Formal Sciences
- Focus on abstract concepts.
- Includes mathematics, logic, and statistics.
-
Social Sciences
- Study of human behavior and societies.
- Includes psychology, sociology, and anthropology.
-
Applied Sciences
- Use of scientific knowledge to solve practical problems.
- Includes engineering and medical sciences.
Scientific Method
- Observation: Identifying phenomena.
- Question: Formulating a question based on observations.
- Hypothesis: Proposing a testable explanation.
- Experimentation: Testing the hypothesis through experiments.
- Analysis: Interpreting the data collected.
- Conclusion: Drawing conclusions from the analysis.
- Communication: Sharing findings with the scientific community.
Key Concepts
- Theory: A well-substantiated explanation of an aspect of the natural world.
- Law: A statement based on repeated experimental observations that describe some aspect of the world.
- Variable: Factors that can change in an experiment (dependent, independent, and controlled).
- Peer Review: Process of evaluation by experts in the field before publication.
Importance of Science
- Advances knowledge and technology.
- Informs public policy and decision-making.
- Promotes critical thinking and problem-solving skills.
