Study Notes
Introduction to Science
- Science is a systematic process of acquiring knowledge about the natural world.
- It involves observation, experimentation, and logical reasoning to understand how things work.
- Science relies on evidence-based reasoning and empirical data.
- Scientific knowledge is constantly being refined and updated as new evidence emerges.
Branches of Science
- Natural sciences study the natural world and its phenomena.
- Physics: Studies matter, energy, and their interactions.
- Chemistry: Studies the composition, structure, properties, and reactions of matter.
- Biology: Studies living organisms and their interactions.
- Earth science: Studies the Earth, its composition, processes, and history.
- Astronomy: Studies the universe, including stars, planets, and galaxies.
- Social sciences study human behavior and society.
- Psychology: Studies the human mind and behavior.
- Sociology: Studies human social behavior and interaction.
- Economics: Studies how individuals and groups allocate scarce resources.
- Political science: Studies government and political systems.
- Anthropology: Studies human origins, cultures, and societies.
Scientific Method
- A systematic approach to understanding the natural world.
- Observation: Recognizing a need to understand something.
- Question: Formulating a question about an observation.
- Hypothesis: Proposing a possible explanation for the question.
- Prediction: Making a testable statement about the expected outcome.
- Experiment: Testing the prediction in a controlled manner.
- Variables: Factors that can be controlled and measured.
- Independent variable: The variable that is manipulated.
- Dependent variable: The variable that is measured.
- Control: A standard against which results are compared.
- Analysis: Interpreting the results from the experiment.
- Conclusion: Determining whether the hypothesis is supported or rejected.
- Communication: Sharing results with others for verification and further study.
Scientific Theories and Laws
- Theories: A well-substantiated explanation of some aspect of the natural world.
- Based on a large body of evidence.
- Supported by multiple lines of investigation.
- Laws: Statements based on observed behavior that are consistent across many experiments.
- Often concise mathematical expressions.
- Summarize observed patterns but don't explain why they occur.
Scientific Process
- Often iterative, with modifications and adjustments based on new data.
- Driven by curiosity and the desire to understand.
- Employs critical and logical thought.
- Involves peer review to ensure accuracy and validity.
Characteristics of Good Science
- Reliability: Consistent results when repeated.
- Validity: Measures what it intends to measure.
- Objectivity: Free from bias.
- Reproducibility: Others can perform the experiment and get similar results.
- Transparency: Clear explanation of methods and data.
- Openness: Willingness to share data and methods.
Ethical Considerations in Science
- Animal welfare and research standards.
- Human subjects' rights and safety protocols.
- Use of scientific knowledge for benefiting society.
- Understanding the potential risks and harms of scientific advancements. Minimizing harm is important.
