Introduction to Science and Its Methods

Definition of Science

• Systematic study of the natural world through observation and experimentation.
• Aims to understand and explain phenomena.

Key Components of Science

1. Observation

   • Gathering data through senses or instruments.

2. Hypothesis

   • A testable prediction based on observations.

3. Experimentation

   • Controlled tests to validate or refute hypotheses.

4. Analysis

   • Interpreting data to draw conclusions.

5. Theory Development

   • Formulating broader explanations based on repeated findings.

Branches of Science

1. Natural Sciences

   • Physics, Chemistry, Biology, Earth Science.

2. Formal Sciences

   • Mathematics, Logic, Computer Science.

3. Social Sciences

   • Psychology, Sociology, Anthropology, Economics.

Scientific Method

• Steps typically include:
  1. Observation
  2. Question formulation
  3. Hypothesis development
  4. Experimentation
  5. Data collection and analysis
  6. Conclusion drawing
  7. Peer review/publication

Importance of Science

Definition of Science

• Systematic study focused on understanding the natural world through observation and experimentation.

Key Components of Science

• Observation: Involves collecting data using senses or scientific instruments to gather information.
• Hypothesis: A testable prediction derived from initial observations, forming the basis for experimentation.
• Experimentation: Conducting controlled tests to either support or challenge the formulated hypothesis.
• Analysis: Interpreting collected data to determine the validity of the hypothesis and draw conclusions.
• Theory Development: Creating broader explanations that integrate consistent findings from multiple studies over time.

Branches of Science

• Natural Sciences: Explore the physical universe, including disciplines like Physics, Chemistry, Biology, and Earth Science.
• Formal Sciences: Focus on abstract concepts and logic, encompassing fields such as Mathematics, Logic, and Computer Science.
• Social Sciences: Investigate human behavior and societies, covering disciplines like Psychology, Sociology, Anthropology, and Economics.

Scientific Method

• Structured approach to inquiry consisting of steps like observation, question formulation, hypothesis development, experimentation, data collection, analysis, conclusion drawing, and peer review/publication.

Importance of Science

• Enriches comprehension of the universe and natural laws.
• Drives technological innovations that improve daily life.
• Informs policymaking and public decisions through data-driven insights.
• Addresses critical societal issues, including public health and environmental challenges.

Characteristics of Scientific Knowledge

• Empirical: Rooted in observable, verifiable evidence.
• Tentative: Open to change when new data emerges, reflecting the dynamic nature of scientific inquiry.
• Testable: Findings must be verifiable through repeatable experiments.
