Study Notes
Definition
- Natural science is a branch of science that studies the physical world and its phenomena.
Branches of Natural Science
-
Physics
- Study of matter, energy, and the fundamental forces of nature.
- Key concepts include motion, force, energy, waves, electricity, and magnetism.
-
Chemistry
- Study of substances, their properties, reactions, and the changes they undergo.
- Areas include organic, inorganic, physical, analytical, and biochemistry.
-
Biology
- Study of living organisms, their structure, function, growth, origin, evolution, and distribution.
- Subfields include microbiology, ecology, genetics, and zoology.
-
Earth Science
- Study of the Earth and its processes, including geology, meteorology, oceanography, and environmental science.
- Focus on the Earth's systems and their interactions.
Scientific Method
- A systematic process used in natural sciences for investigating phenomena.
- Observation: Gathering information through the senses.
- Hypothesis: Proposing an explanation based on observations.
- Experimentation: Testing the hypothesis through controlled experiments.
- Analysis: Interpreting data collected from experiments.
- Conclusion: Drawing conclusions based on the analysis.
- Replication: Repeating experiments to verify findings.
Importance
- Enhances understanding of the natural world.
- Provides foundation for technological advancements and innovations.
- Informs public policy and environmental conservation efforts.
Applications
- Medicine (pharmacology, genetics)
- Environmental science (climate change, conservation)
- Engineering (material science, renewable energy)
- Agriculture (crop science, biotechnology)
Key Concepts
- Matter: Anything that has mass and occupies space.
- Energy: The capacity to do work or produce change.
- Ecosystems: Interaction of living organisms with their environment.
- Chemicals: Substances formed from atoms and molecules.
Interdisciplinary Nature
- Natural science overlaps with social sciences (e.g., psychology, anthropology) and formal sciences (e.g., mathematics, computer science) to address complex problems.
