Introduction to Science and Its Branches

Definition of Science

• Systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

Branches of Science

1. Natural Sciences

   • Study of natural phenomena.
   • Includes:
     • Physics: Study of matter, energy, and their interactions.
     • Chemistry: Study of substances, their properties, and reactions.
     • Biology: Study of living organisms and life processes.

2. Formal Sciences

   • Study of abstract concepts and logical systems.
   • Includes:
     • Mathematics: Study of numbers, quantities, and shapes.
     • Logic: Study of reasoning principles.
     • Statistics: Study of data collection and analysis.

3. Social Sciences

   • Study of human behavior and societies.
   • Includes:
     • Psychology: Study of the mind and behavior.
     • Sociology: Study of social behavior and society.
     • Economics: Study of production, consumption, and distribution of goods.

Scientific Method

• Steps involved:
  1. Observation: Gathering data through the senses.
  2. Question: Formulating a question based on observations.
  3. Hypothesis: Proposing a testable explanation.
  4. Experiment: Conducting experiments to test the hypothesis.
  5. Analysis: Analyzing data and results.
  6. Conclusion: Drawing conclusions that support or refute the hypothesis.
  7. Communication: Sharing findings with the scientific community.

Importance of Science

• Advances knowledge and understanding of the world.
• Drives technological innovation and medical advancements.
• Informs policy decisions and ethical considerations.
• Promotes critical thinking and problem-solving skills.

Key Concepts

• Theory: Well-substantiated explanation of some aspect of the natural world; supported by evidence.
• Law: Statement based on repeated experimental observations that describes some aspects of the universe.
• Experimentation: Fundamental process in science to test hypotheses and observe phenomena under controlled conditions.

Ethical Considerations in Science

• Importance of integrity and honesty in research.
• Issues of consent, privacy, and the use of animals in research.
• Responsible communication of scientific information to the public.

Current Trends
