Introduction to Science

Definition of Science

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

Branches of Science

1. Natural Sciences

   • Focus on the physical world.
   • Includes physics, chemistry, biology, and earth sciences.

2. Formal Sciences

   • Study of abstract concepts.
   • Includes mathematics, logic, and statistics.

3. Social Sciences

   • Study of human behavior and societies.
   • Includes psychology, sociology, and economics.

4. Applied Sciences

   • Practical application of scientific knowledge.
   • Includes engineering, medicine, and technology.

Scientific Method

1. Observation

   • Identify a phenomenon or problem.

2. Question

   • Formulate questions based on observations.

3. Hypothesis

   • Propose a testable explanation.

4. Experimentation

   • Conduct experiments to test the hypothesis.

5. Analysis

   • Analyze data and draw conclusions.

6. Reporting

   • Share results with the scientific community.

Key Concepts

• Theory: A well-substantiated explanation of an aspect of the natural world.
• Law: A statement based on repeated experimental observations that describe some aspect of the world.
• Variable: An element that can be changed or controlled in an experiment.
• Control: A standard for comparison in an experiment.

Role of Technology

• Enhances data collection and analysis.
• Facilitates experimentation and simulation.
• Aids in communication of scientific findings.

Importance of Science

• Fosters critical thinking and problem-solving skills.
• Drives innovation and technological advancements.
• Informs public policy and societal decisions.
• Enhances understanding of the universe and our place in it.
