Overview of Science and the Scientific Method

Study Notes

Overview of Science

Definition: Systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
Branches of Science:
- Natural Sciences: Study of natural phenomena (e.g., physics, chemistry, biology).
- Social Sciences: Study of societies and human behavior (e.g., psychology, sociology, economics).
- Formal Sciences: Study of abstract concepts and systems (e.g., mathematics, logic).
- Applied Sciences: Practical application of scientific knowledge (e.g., engineering, medicine).

Scientific Method

Observation: Gathering data through sensory experiences or instruments.
Question: Formulating questions based on observations.
Hypothesis: Proposing a testable explanation or prediction.
Experimentation: Designing and conducting experiments to test the hypothesis.
Analysis: Interpreting data to determine if it supports or refutes the hypothesis.
Conclusion: Drawing conclusions from the analysis.
Replication: Repeating experiments to verify results.

Key Concepts

Theory vs. Law:
- Theory: A well-substantiated explanation of some aspect of the natural world (e.g., theory of evolution).
- Law: A statement that describes an observable phenomenon (e.g., Newton's laws of motion).
Variables in Experiments:
- Independent Variable: The factor that is manipulated.
- Dependent Variable: The factor that is measured.
- Control Variables: Factors kept constant to ensure valid results.

Importance of Science

Advancement of Knowledge: Contributes to understanding natural laws and processes.
Problem Solving: Provides tools and methodologies for solving complex issues.
Technological Innovation: Drives development of new technologies that improve quality of life.

Ethics in Science

Integrity: Ensuring honesty and transparency in research.
Responsibility: Scientists are accountable for the societal impact of their research.
Respect for Subjects: Ethical treatment of human and animal subjects in research.

Scientific Literacy

Definition: The ability to understand and use scientific information.
Importance: Enables individuals to make informed decisions on scientific issues and appreciate the role of science in society.

Overview of Science

Science is a systematic approach to understanding the universe through testable explanations and predictions.

Branches of Science

Natural Sciences study the natural world (e.g., physics, chemistry, biology)
Social Sciences analyze societies and human behavior (e.g., psychology, sociology, economics)
Formal Sciences deal with abstract concepts and systems (e.g., mathematics, logic)
Applied Sciences use scientific knowledge for practical applications (e.g., engineering, medicine)

Scientific Method

The scientific method is a systematic process for gathering, interpreting, and verifying information.
It involves observation, questioning, forming a testable hypothesis, conducting experiments, analyzing data, drawing conclusions, and replicating experiments.

Key Concepts

Theory: A well-supported explanation of a natural phenomenon (e.g., theory of evolution)
Law: A statement describing an observable phenomenon (e.g., Newton's laws of motion)
Variables in Experiments:
- Independent Variable: The factor that is manipulated
- Dependent Variable: The factor that is measured
- Control Variables: Factors kept constant to ensure reliable results
