Introduction to Science and Its Branches

Study Notes

Definition of Science

Systematic study of the natural world through observation and experimentation.
Aims to build and organize knowledge in the form of testable explanations and predictions.

Branches of Science

Natural Sciences
- Focus on the physical world.
- Subfields: Physics, Chemistry, Biology, Earth Science.
Formal Sciences
- Study abstract concepts and logic.
- Subfields: Mathematics, Statistics, Computer Science.
Social Sciences
- Study human behavior and societies.
- Subfields: Psychology, Sociology, Anthropology, Economics.

Scientific Method

A systematic approach to inquiry that includes:
1. Observation: Gathering data through senses.
2. Question: Identifying phenomena to investigate.
3. Hypothesis: Proposing a testable explanation.
4. Experimentation: Testing the hypothesis through controlled methods.
5. Analysis: Interpreting data collected during experiments.
6. Conclusion: Drawing inferences based on experimental results.
7. Replication: Repeating experiments to validate results.

Key Concepts

Theory: A well-substantiated explanation of an aspect of the natural world, based on a body of evidence (e.g., Theory of Evolution).
Law: A statement that describes a consistent natural phenomenon (e.g., Newton's Laws of Motion).
Hypothesis: A proposed explanation that can be tested through experimentation.

Importance of Science

Advances knowledge and technology.
Addresses real-world problems (e.g., climate change, health issues).
Promotes critical thinking and informed decision-making.

Science and Society

Science influences policies and education.
Ethical considerations in scientific research (e.g., human and animal testing).
Public understanding of science is crucial for informed citizenship.

Current Trends in Science

Interdisciplinary research (e.g., biochemistry, environmental science).
Emerging fields (e.g., artificial intelligence, genomics).
Focus on sustainability and global health challenges.

Definition of Science

Scientific Method

Observation: Collecting data using sensory experience.
Question: Identifying specific phenomena for investigation.
Hypothesis: Formulating a testable statement to explain observations.
Experimentation: Conducting controlled tests to evaluate the hypothesis.
Analysis: Evaluating experimental data to draw interpretations.
Conclusion: Making inferences based on analyzed results.
Replication: Repeating experiments to confirm reliability of findings.

Key Concepts

Theory: A comprehensive explanation based on extensive evidence, such as the Theory of Evolution.
Law: A general statement about consistent natural phenomena, exemplified by Newton's Laws of Motion.
Hypothesis: A tentative explanation that is subject to testing through experiments.

Importance of Science
