Introduction to Science

Study Notes

Definition of Science

Systematic enterprise that builds and organizes knowledge.
Involves observation, experimentation, and analysis.

Branches of Science

Natural Sciences: Study of natural phenomena.
- Examples: Physics, Chemistry, Biology.
Social Sciences: Study of societies and human behavior.
- Examples: Psychology, Sociology, Economics.
Formal Sciences: Study of abstract concepts.
- Examples: Mathematics, Logic, Computer Science.
Applied Sciences: Practical application of scientific knowledge.
- Examples: Engineering, Medicine, Environmental Science.

Scientific Method

Observation: Gathering data through senses.
Question: Formulating a question based on observations.
Hypothesis: Proposing an explanation or prediction.
Experimentation: Testing the hypothesis under controlled conditions.
Analysis: Interpreting data collected from experiments.
Conclusion: Drawing conclusions based on analysis; may lead to further questions.

Key Concepts

Theory: A well-substantiated explanation of an aspect of the natural world.
Law: A statement based on repeated experimental observations that describes some aspect of the world.
Variables: Factors that can change in an experiment.
- Independent Variable: Manipulated by the researcher.
- Dependent Variable: Measured in the experiment.
- Control Variables: Kept constant to ensure validity.

Hypothesis: Suggests a potential explanation or prediction regarding the observation.
Experimentation: Involves testing the hypothesis in controlled conditions to gather data.
Analysis: Involves interpreting the data collected during experiments.
Conclusion: Derives insights based on the analysis, which may prompt additional questions.

Key Concepts

Theory: Represents a comprehensive explanation of certain aspects of the natural world, supported by substantial evidence.
Law: Defines a regularly observed phenomenon, articulating what happens under specific conditions.
Variables: Elements that can change in experimental setups:
- Independent Variable: Deliberately modified by the researcher.
- Dependent Variable: Measured outcome that responds to changes in the independent variable.
- Control Variables: Factors maintained constant to ensure experiment validity.
