Study Notes
Understanding Science
- Originates from the Latin word "scire," meaning "to know."
- Defined as a systematic body of knowledge and a method for acquiring knowledge about the world.
- Focuses on consistent explanations connecting beliefs and observations.
Scientific Method
- Organized process used to answer questions or solve problems.
- Generally follows these core steps:
- Make an observation
- Ask a question
- Form a hypothesis (a testable explanation)
- Make a prediction based on the hypothesis
- Test the prediction
- Iterate based on results, refining hypotheses or predictions.
Application Across Disciplines
- Utilized in various scientific fields, including biology, chemistry, physics, geology, and psychology.
- Each field may ask different questions and conduct varied tests, but the same core approach is applied.
Experimentation Components
- Independent Variable: The factor that is tested or varied to address the hypothesis.
- Dependent Variable: The factor that changes in response to the independent variable.
- Constants: Controlled variables that remain unchanged throughout the experimentation.
Data Organization and Analysis
- Post-experiment data must be organized using graphs, tables, or charts.
- Data is analyzed to make generalizations and contribute to scientific knowledge.
Nature of Scientific Knowledge
- Accumulates through observation and experimentation, leading to the formulation of theories.
- Theories represent scientifically accepted principles and can evolve over time, illustrating the dynamic nature of science.
Values and Ethics in Science
- Science is viewed as a study of systematically arranged knowledge demonstrating general laws.
- Ethics governs the conduct of scientists, emphasizing honesty and integrity in reporting results.
- Ethical considerations also include the humane treatment of living subjects in research, highlighting the moral responsibility inherent in scientific work.
Importance of Ethics
- Scientists must avoid personal biases such as egoism, greed, or prejudice that can compromise integrity.
- Promotion of science must be paired with growth in moral values to foster human development.
