Introduction to Science

Study Notes

Definition of Science

Systematic study of the natural world.
Utilizes observation, experimentation, and analysis.

Branches of Science

Physical Sciences
- Focus on non-living systems.
- Includes physics, chemistry, astronomy, and geology.
Life Sciences
- Study of living organisms.
- Includes biology, ecology, genetics, and microbiology.
Formal Sciences
- Concerned with abstract concepts and logical reasoning.
- Includes mathematics, statistics, and computer science.
Social Sciences
- Study of human behavior and societies.
- Includes psychology, sociology, anthropology, and economics.

Scientific Method

Observation
- Gathering information through senses.
Question
- Formulating a question based on observations.
Hypothesis
- Proposing a testable explanation or prediction.
Experimentation
- Conducting experiments to test the hypothesis.
Analysis
- Interpreting data collected during experiments.
Conclusion
- Drawing conclusions to support or refute the hypothesis.
Replication
- Repeating experiments to validate findings.

Key Concepts

Theory vs. Law
- Theory: A well-substantiated explanation of an aspect of the natural world.
- Law: A statement based on repeated experimental observations that describe an aspect of the world.
Variables
- Independent Variable: The factor manipulated in an experiment.
- Dependent Variable: The factor measured in response to changes in the independent variable.
Peer Review
- The process of evaluating scientific work by other experts in the field before publication.

Importance of Science

Advances technology and medicine.
Enhances understanding of the natural world.
Informs policy and decision-making.
Encourages critical thinking and problem-solving.

Scientific Literacy

The ability to understand and engage with scientific concepts and processes.
Essential for informed citizenship and personal decision-making.
