Introduction to Science and Its Branches

Study Notes

Definition of Science

Systematic study of the natural world.
Involves observation, experimentation, and analysis.

Branches of Science

Physical Sciences
- Physics: Study of matter, energy, and their interactions.
- Chemistry: Study of substances, their properties, and reactions.
- Astronomy: Study of celestial bodies and the universe.
Life Sciences
- Biology: Study of living organisms, their structures, functions, and interactions.
- Ecology: Study of ecosystems and environmental interactions.
- Genetics: Study of heredity and variation in organisms.
Earth Sciences
- Geology: Study of the Earth, its materials, and processes.
- Meteorology: Study of the atmosphere and weather.
- Oceanography: Study of ocean dynamics, ecosystems, and geology.
Formal Sciences
- Mathematics: Study of numbers, quantities, and shapes.
- Computer Science: Study of computational systems and technologies.

Scientific Method

Observation: Gathering data through senses or instruments.
Hypothesis: Formulating a testable explanation for observations.
Experimentation: Testing the hypothesis through controlled experiments.
Analysis: Evaluating data to determine if it supports the hypothesis.
Conclusion: Drawing conclusions based on analysis; may lead to further testing or new hypotheses.
Communication: Sharing results with the scientific community.

Importance of Science

Advances technology and medicine.
Informs public policy and environmental protection.
Enhances understanding of the universe and our place in it.

Key Concepts

Theory: A well-substantiated explanation based on a body of evidence (e.g., theory of evolution).
Law: A statement describing a natural phenomenon (e.g., Newton's laws of motion).
Peer Review: Process of evaluation by experts in the field before publication.

Ethics in Science

Integrity and honesty in research.
Ethical treatment of subjects (human and animal).
Responsibility in communicating findings and addressing societal impacts.
