Study Notes

Branches of Science

Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
It is divided into various branches, each focusing on a specific area of study.

Physical Sciences

Physical sciences study non-living matter and energy.
Key branches include:
- Physics: Studies matter, energy, and their interactions. This includes areas like mechanics, thermodynamics, electromagnetism, and nuclear physics.
- Chemistry: Studies the composition, structure, properties, and reactions of matter. This includes areas like organic chemistry, inorganic chemistry, and physical chemistry.
- Astronomy: Studies celestial objects like planets, stars, galaxies, and the universe as a whole.

Biological Sciences

Biological sciences study living organisms and their processes.
Key branches include:
- Biology: A broad field encompassing the study of all living things, their structures, functions, evolution, distribution, and interactions.
- Botany: Studies plants.
- Zoology: Studies animals.
- Microbiology: Studies microorganisms like bacteria, viruses, and fungi.
- Ecology: Studies the interactions between organisms and their environment.
- Genetics: Studies heredity and the variation of inherited characteristics.

Earth Sciences

Earth sciences study the Earth's structure, processes, and history.
Key branches include:
- Geology: Studies the Earth's physical structure, processes, and history.
- Meteorology: Studies weather patterns and atmospheric phenomena.
- Oceanography: Studies the oceans, including their currents, tides, and life.
- Astronomy (overlapping): Studies celestial objects and phenomena relevant to Earth's systems, including the sun and its effects on Earth's climate.

Methods of Science

The scientific method is a systematic approach to understanding the natural world.
- Observation: Notice something interesting.
- Question: Formulate a question about the observation.
- Hypothesis: Propose a possible answer to the question.
- Prediction: Predict the outcome if the hypothesis is correct.
- Experiment: Design and conduct an experiment to test the prediction.
- Analysis: Analyze the results of the experiment.
- Conclusion: Draw conclusions based on the analysis.
Scientific investigations often involve collecting data, analyzing data, drawing conclusions, and communicating findings through reports and presentations.

Scientific Principles

Empirical evidence: Evidence based on observation and experimentation.
Reproducibility: Results of experiments should be repeatable by others.
Falsifiability: Hypotheses must be testable in such a way that they could potentially be proven wrong.
Objectivity: Avoid bias in observations and interpretations.
Skepticism: Question claims and seek evidence.
Peer review: Validation of scientific findings by other experts.
The scientific process is a dynamic process of inquiry, revision, and refinement, not a rigid set of steps.
