Study Notes
Introduction to Science
- Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
- It's a process, not a body of knowledge.
- It involves observation, experimentation, and the formulation of hypotheses to test theories.
- Scientific knowledge is continually refined and updated as new evidence emerges.
Branches of Science
- Natural Sciences focus on the natural world, studying the physical and biological phenomena.
- Physics: the study of matter, energy, and their interactions.
- Chemistry: the study of matter and its properties, including how matter changes.
- Biology: the study of life and living organisms.
- Earth Science: study of the Earth and its systems (geology, oceanography, meteorology, astronomy).
- Social Sciences examine human behaviour and social interactions.
- Anthropology: study of human societies and cultures.
- Psychology: study of the mind and behavior of individuals.
- Sociology: study of human social relationships and institutions.
- Economics: study of how societies allocate scarce resources.
- Political Science: study of the state and government.
Scientific Method
- Observation: noticing a phenomenon.
- Question: formulating a question based on the observation.
- Hypothesis: proposing a possible explanation or prediction based on prior knowledge or observations.
- Prediction: outlining what will happen if the hypothesis is correct.
- Experiment: designing and conducting tests to gather data.
- Analysis: examining the data to draw conclusions.
- Conclusion: determining if the data supports or refutes the hypothesis.
Key Concepts in Science
- Data: factual information collected during an experiment or observation.
-
Variables: factors that can change in an experiment.
- Independent variable: the variable that's manipulated by the researcher.
- Dependent variable: the variable measured during the experiment.
- Control variables: factors that are kept constant to avoid influencing the outcome.
- Theory: a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.
- Law: a descriptive generalization about how some aspect of the natural world behaves under stated circumstances.
Scientific Communication
- Scientists use peer-reviewed publications to share their research with the scientific community.
- This process allows other scientists to evaluate the work and ensures the validity of findings.
- Conferences are another important avenue for scientific communication.
- Clarity, accuracy, and reproducibility in research are paramount.
Ethical Considerations in Science
- Maintaining objectivity and honesty is crucial.
- Avoiding bias is important to ensure scientific integrity.
- Protecting human subjects and the environment are central ethical concerns.
- Transparency in research methods and data analysis strengthens the credibility of scientific investigations.
Science and Society
- Science affects various aspects of modern life, including technology, medicine, and environmental policy.
- Public understanding of scientific concepts is important for informed decision making.
- Critical thinking and skepticism are vital for assessing scientific claims.
- Misinformation and pseudoscience can hinder progress, so it's important to distinguish between scientific evidence and unsubstantiated claims.
