Introduction to Science and Its Branches

Definition of Science

• Systematic study of the natural world.
• Involves observation, experimentation, and analysis.

Branches of Science

1. Natural Sciences

   • Physics: Study of matter, energy, and their interactions.
   • Chemistry: Study of substances, their properties, and reactions.
   • Biology: Study of living organisms and life processes.
   • Earth Sciences: Study of Earth's structure, processes, and components (geology, meteorology, oceanography).

2. Formal Sciences

   • Mathematics: Study of numbers, quantities, shapes, and patterns.
   • Logic: Study of reasoning and argument structures.
   • Computer Science: Study of computation, algorithms, and information processing.

3. Social Sciences

   • Psychology: Study of behavior and mental processes.
   • Sociology: Study of society and social behavior.
   • Economics: Study of production, distribution, and consumption of goods/services.

Scientific Method

1. Observation: Identifying a phenomenon or problem.
2. Research: Gathering existing information.
3. Hypothesis: Formulating a testable prediction.
4. Experimentation: Designing and conducting experiments to test the hypothesis.
5. Analysis: Interpreting data and results.
6. Conclusion: Drawing conclusions based on the analysis.
7. Reporting: Sharing findings with the scientific community.

Key Concepts

• Theory: A well-substantiated explanation of an aspect of the natural world.
• Law: A statement that describes consistent observations (e.g., laws of motion).
• Variable: A factor that can be changed in an experiment (independent, dependent, controlled).

Importance of Science

• Advances knowledge and technology.
• Informs public policy and decision-making.
• Addresses global challenges (e.g., climate change, health crises).
• Promotes critical thinking and problem-solving skills.

Definition of Science

• Systematic study aimed at understanding the natural world.
• Employs observation, experimentation, and analysis as core methods.

Branches of Science

• Natural Sciences focus on the physical world and include:

  • Physics: Examines matter, energy, and their interactions.
  • Chemistry: Investigates substances, their properties, and reactions.
  • Biology: Studies living organisms and their life processes.
  • Earth Sciences: Explores Earth's structure and processes, encompassing geology, meteorology, and oceanography.

• Formal Sciences concern abstract concepts and include:

  • Mathematics: Analyzes numbers, quantities, shapes, and patterns.
  • Logic: Investigates reasoning and argument structures.
  • Computer Science: Focuses on computation, algorithms, and information processing.

• Social Sciences study human behavior and societies:

  • Psychology: Analyzes behavior and mental processes.
  • Sociology: Examines society and social behavior.
  • Economics: Studies the production, distribution, and consumption of goods and services.

Scientific Method

• Observation: Recognition of a phenomenon or problem.
• Research: Accumulating existing knowledge relevant to the observation.
• Hypothesis: Crafting a testable prediction based on the gathered information.
• Experimentation: Creating and conducting experiments to validate the hypothesis.
• Analysis: Interpreting the gathered data and results.
• Conclusion: Formulating conclusions derived from the analysis.
• Reporting: Disseminating findings to the scientific community for peer review.

Key Concepts

• Theory: A thoroughly supported explanation of a natural phenomenon.
• Law: A statement reflecting consistent observations, such as the laws of motion.
• Variable: Factors in an experiment that can vary, categorized as independent, dependent, or controlled.

Importance of Science

• Drives advancements in knowledge and technology.
• Shapes public policy and aids decision-making processes.
• Tackles global issues such as climate change and health emergencies.
• Fosters critical thinking and enhances problem-solving capabilities.
