Introduction to Science Overview

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.
