Overview of Science and Its Branches

Definition of Science

• Systematic enterprise that builds and organizes knowledge.
• Utilizes empirical methods to acquire and test knowledge.

Branches of Science

1. Natural Sciences

   • Study of the natural world.
   • Includes:
     • Physics: Study of matter and energy.
     • Chemistry: Study of substances and their interactions.
     • Biology: Study of living organisms.
     • Earth Science: Study of Earth and its processes (geology, meteorology, oceanography).

2. Formal Sciences

   • Study of abstract concepts and systems.
   • Includes:
     • Mathematics: Study of numbers, quantities, and shapes.
     • Logic: Study of reasoning and argument.

3. Social Sciences

   • Study of human behavior and societies.
   • Includes:
     • Psychology: Study of the mind and behavior.
     • Sociology: Study of social behavior and societies.
     • Anthropology: Study of cultures and human development.

4. Applied Sciences

   • Application of scientific knowledge to practical problems.
   • Includes:
     • Engineering: Design and construction of structures and systems.
     • Medicine: Science of diagnosing and treating illnesses.

Scientific Method

• A systematic approach to research and experimentation.

1. Observation: Gathering data through the senses.
2. Question: Formulating a question based on observations.
3. Hypothesis: Proposing a testable explanation.
4. Experimentation: Conducting experiments to test the hypothesis.
5. Analysis: Interpreting data collected during experiments.
6. Conclusion: Determining whether the hypothesis is supported or refuted.
7. Communication: Sharing findings with the scientific community.

Importance of Science

• Enhances understanding of the natural world.
• Drives technological advancements and innovation.
• Informs policy-making and addresses societal challenges.
• Promotes critical thinking and problem-solving skills.

Key Concepts

• Theory: A well-substantiated explanation of an aspect of the natural world.
• Law: A statement based on repeated experimental observations that describe a natural phenomenon.
• Data: Factual information collected during research; can be qualitative or quantitative.

Ethical Considerations

• Importance of honesty, integrity, and objectivity in research.
• Ethical treatment of human and animal subjects.
• Responsible communication of scientific findings.

Definition of Science

Scientific Method

• A structured approach utilized in research and experimentation, consisting of:
  • Observation: Collecting data through sensory experiences.
  • Question: Developing inquiries based on observed phenomena.
  • Hypothesis: Creating a testable proposition to explain observations.
  • Experimentation: Performing tests to evaluate the hypothesis.
  • Analysis: Interpreting experimental data to draw conclusions.
  • Conclusion: Deciding if the hypothesis is supported or contradicted.
  • Communication: Disseminating findings to the scientific community.

Importance of Science

• Science enhances our understanding of natural phenomena.
• It fuels technological advancements and innovation.
• Provides a foundation for informed policy-making and resolving societal issues.
• Fosters critical thinking and problem-solving abilities.

Key Concepts

• Theory: A comprehensive explanation based on extensive evidence regarding a natural phenomenon.
• Law: A description of observed phenomena, consistently validated through experimentation.
• Data: Information gathered during research, which can be qualitative (descriptive) or quantitative (numerical).

Ethical Considerations

• Research integrity necessitates honesty, objectivity, and transparency.
• Ethical treatment is crucial for human and animal subjects in research.
• Responsible communication is essential for conveying scientific results accurately.
