Study Notes
Branches of Science
-
Natural Sciences:
- Study of natural phenomena and laws of nature
- Includes biology, chemistry, physics, and earth sciences
-
Formal Sciences:
- Focus on abstract structures and formal systems
- Includes mathematics, logic, and computer science
-
Applied Sciences:
- Practical application of scientific knowledge
- Includes engineering, medicine, and technology
Scientific Method
- Observation: Identify a problem or phenomenon
- Hypothesis: Formulate a testable explanation
- Prediction: Make a forecast based on the hypothesis
- Experimentation: Design and conduct experiments to test the hypothesis
- Analysis: Interpret data and draw conclusions
- Conclusion: Accept, reject, or modify the hypothesis
Key Scientific Concepts
- Theories: Well-substantiated explanations for a set of phenomena
- Hypotheses: Testable predictions based on a theory
- Laws: Descriptive statements of natural phenomena
- Variables: Factors that can be changed or controlled in an experiment
- Control Groups: Groups used as a standard of comparison in an experiment
- Empiricism: The idea that knowledge comes from sense experience and observation
Branches of Science
- Natural Sciences study natural phenomena and laws of nature, including biology, chemistry, physics, and earth sciences.
- Formal Sciences focus on abstract structures and formal systems, including mathematics, logic, and computer science.
- Applied Sciences involve the practical application of scientific knowledge, including engineering, medicine, and technology.
Scientific Method
- Observation: Identify a problem or phenomenon, which is the first step in the scientific method.
- Hypothesis: Formulate a testable explanation, which is a prediction based on limited data.
- Prediction: Make a forecast based on the hypothesis, which is a specific and measurable outcome.
- Experimentation: Design and conduct experiments to test the hypothesis, which involves data collection and analysis.
- Analysis: Interpret data and draw conclusions, which involves identifying patterns and trends.
- Conclusion: Accept, reject, or modify the hypothesis, which is the final step in the scientific method.
Key Scientific Concepts
- Theories: Well-substantiated explanations for a set of phenomena, which are based on a large amount of data and evidence.
- Hypotheses: Testable predictions based on a theory, which are used to make predictions and forecast outcomes.
- Laws: Descriptive statements of natural phenomena, which are based on consistent patterns and observations.
- Variables: Factors that can be changed or controlled in an experiment, which are used to test hypotheses and identify cause-and-effect relationships.
- Control Groups: Groups used as a standard of comparison in an experiment, which are used to provide a baseline for measuring the effect of a variable.
- Empiricism: The idea that knowledge comes from sense experience and observation, which is a fundamental principle of scientific inquiry.
