Study Notes
Definition of Science
- Systematic study of the natural world.
- Based on observation, experimentation, and evidence.
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 and their interactions.
- Ecology: Study of ecosystems and environmental interactions.
- Genetics: Study of heredity and variation in organisms.
-
Earth Sciences
- Geology: Study of the Earth’s structure, processes, and history.
- Meteorology: Study of weather and atmospheric phenomena.
- Oceanography: Study of oceans and marine systems.
-
Formal Sciences
- Mathematics: Study of numbers, quantities, and shapes.
- Logic: Study of reasoning and argumentation.
- Computer Science: Study of computation and information processing.
Scientific Method
- Observation: Identifying a phenomenon or problem.
- Research: Gathering existing information.
- Hypothesis: Formulating a testable explanation.
- Experimentation: Testing the hypothesis through controlled experiments.
- Analysis: Interpreting data and results.
- Conclusion: Drawing conclusions based on experimental evidence.
- Communication: Sharing findings with the scientific community.
Key Concepts in Science
- Theory: A well-substantiated explanation of an aspect of the natural world.
- Law: A statement based on repeated experimental observations that describes some aspect of the universe.
-
Variable: Any factor that can change in an experiment.
- Independent Variable: The factor that is manipulated.
- Dependent Variable: The factor that is measured.
- Control Group: The group that does not receive the experimental treatment for comparison.
Importance of Science
