Introduction to Science

Definition of Science

• Systematic enterprise that builds and organizes knowledge.
• Involves observation, experimentation, and analysis.

Branches of Science

1. Natural Sciences
   • Study of the natural world (e.g., physics, chemistry, biology).
2. Formal Sciences
   • Study of abstract concepts (e.g., mathematics, logic, statistics).
3. Social Sciences
   • Study of societies and relationships (e.g., psychology, sociology, anthropology).
4. Applied Sciences
   • Practical applications of scientific knowledge (e.g., engineering, medicine).

Scientific Method

1. Observation
   • Identifying phenomena or problems.
2. Hypothesis
   • Formulating testable statements.
3. Experimentation
   • Conducting controlled tests.
4. Analysis
   • Interpreting data to support or refute the hypothesis.
5. Conclusion
   • Summarizing findings and implications.
6. Replication
   • Repeating experiments to validate results.

Key Concepts

• Theory
  • Well-substantiated explanation of aspects of the natural world.
• Law
  • Statement based on repeated experiments that describes a fundamental relationship.
• Variable
  • Any factor that can change in an experiment (independent, dependent, controlled).
• Peer Review
  • Process of evaluation by other experts in the field before publication.

Importance of Science

• Enhances understanding of the universe.
• Drives technological advancement and innovation.
• Addresses societal challenges (e.g., health, environment).
• Promotes critical thinking and evidence-based decision-making.

Ethical Considerations

• Responsible conduct in research.
• Integrity in data reporting.
• Consideration of the societal impact of scientific findings.

Definition of Science

• A systematic enterprise focused on building and organizing knowledge.
• Utilizes observation, experimentation, and analysis as foundational processes.

Branches of Science

• Natural Sciences: Investigate the natural world, encompassing disciplines like physics, chemistry, and biology.
• Formal Sciences: Deal with abstract concepts and include fields such as mathematics, logic, and statistics.
• Social Sciences: Explore societies and interpersonal relationships, covering psychology, sociology, and anthropology.
• Applied Sciences: Focus on practical applications of scientific knowledge in areas like engineering and medicine.

Scientific Method

• Observation: Begin by recognizing phenomena or problems that need study.
• Hypothesis: Develop testable statements predicting outcomes.
• Experimentation: Conduct controlled tests to gather data.
• Analysis: Examine data to determine if it supports or contradicts the hypothesis.
• Conclusion: Summarize the findings and their implications, offering insights.
• Replication: Repeated experiments are crucial to confirm the validity of the results.

Key Concepts

• Theory: A robust explanation that has been extensively validated regarding natural phenomena.
• Law: A concise statement derived from consistent experimental results, outlining fundamental relationships.
• Variable: Any element in an experiment that can change; categorized as independent, dependent, or controlled.
• Peer Review: An evaluative process whereby experts in the field assess research prior to publication, ensuring quality and credibility.

Importance of Science

• Advances comprehension of the universe and its workings.
• Fuels technological progress and fosters innovation.
• Tackles significant societal challenges, including health and environmental issues.
• Encourages critical thinking and supports decision-making based on empirical evidence.

Ethical Considerations

• Emphasizes the necessity of responsible practices in research.
• Insists on integrity and transparency in data reporting.
• Promotes awareness of the societal impacts resulting from scientific research and findings.
