Study Notes
Branches of Science
- Science is a systematic approach to understanding the universe, organized into testable explanations and predictions.
- It's a constantly evolving body of knowledge, refined through observations and experiments.
- Science is broadly categorized into separate branches, each focusing on a specific aspect of the natural world.
Physical Sciences
- These branches focus on matter, energy, and forces.
- Physics: Explores fundamental concepts like motion, energy, force, and the structure of matter and the universe.
- Chemistry: Studies matter's composition, structure, properties, and reactions.
- Astronomy: Investigates celestial objects (planets, stars, galaxies, the universe).
Biological Sciences
- These branches study living organisms and their interactions.
-
Biology: Covers topics from cells to ecosystems. Sub-disciplines include:
- Botany: The study of plants.
- Zoology: The study of animals.
- Microbiology: The study of microorganisms (bacteria, viruses, fungi).
- Genetics: Studies genes and heredity.
- Ecology: Examines the interactions between organisms and their environment.
Earth and Environmental Sciences
- These branches focus on Earth systems and their relationship with the environment.
- Geology: Analyzes Earth's structure, processes, and history.
- Meteorology: Studies atmospheric phenomena (weather, climate).
- Oceanography: Focuses on oceans' physical, biological, and geological aspects.
- Environmental science: Investigates the interplay between human activity and the environment.
Scientific Method
- A systematic approach to investigating phenomena, including:
- Observation: Identifying a question or problem.
- Hypothesis: A testable explanation or prediction.
- Experimentation: Controlled tests to validate the hypothesis.
- Data analysis: Analyzing the results.
- Conclusion: Evaluating the hypothesis based on data.
- The process is iterative, involving repeated testing and refinement of hypotheses.
Scientific Principles
- Objectivity: Scientists seek to minimize bias in observations and interpretations.
- Reproducibility: Experimental findings should be repeatable by others.
- Falsifiability: Hypotheses must be testable and potentially disprovable.
- Openness and Peer Review: Sharing and evaluating findings within scientific communities.
- Skepticism: Approaching claims with scrutiny and requiring strong evidence for acceptance.
Nature of Science
- Science is an ongoing process of inquiry, not just a collection of facts.
- Science constantly evolves due to new discoveries.
- Science relies on empirical evidence (observations, experiments).
- Scientific theories explain observations and experiments; they can be modified or replaced with more complete understandings.
- Science focuses on natural phenomena, not religious or philosophical issues.
