Introduction to Science

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 fields like Biology, Chemistry, Physics, Earth Science, and Astronomy.

2. Formal Sciences

   • Study of abstract concepts and theories.
   • Includes Mathematics, Logic, and Statistics.

3. Social Sciences

   • Study of human behavior and societies.
   • Includes Psychology, Sociology, Anthropology, and Economics.

Scientific Method

1. Observation: Identifying a phenomenon or problem.
2. Question: Formulating a question based on observations.
3. Hypothesis: Proposing an explanation or prediction.
4. Experimentation: Testing the hypothesis through controlled experiments.
5. Analysis: Examining data collected from experiments.
6. Conclusion: Drawing conclusions based on data analysis.
7. Communication: Sharing results with the scientific community.

Characteristics of Scientific Knowledge

• Empirical: Based on observation and experimentation.
• Repeatable: Experiments must yield consistent results when repeated.
• Falsifiable: Hypotheses must be testable and potentially disproven.
• Progressive: Knowledge evolves over time with new discoveries and technologies.

Types of Scientific Investigations

• Descriptive: Observing and describing characteristics of phenomena.
• Comparative: Comparing two or more groups or conditions.
• Experimental: Manipulating variables to determine effects.

Importance of Science

• Advances technology and medicine.
• Enhances understanding of the universe.
• Addresses global challenges (e.g., climate change, health crises).
• Supports evidence-based decision-making in policy and economics.

Ethics in Science

• Integrity in data reporting.
• Honesty in research results.
• Respect for human and animal rights in experimentation.
• Transparency and reproducibility in studies.

Definition of Science

• Science is a systematic approach to understanding the universe through testable explanations and predictions.

Branches of Science

• Natural sciences focus on natural phenomena and include fields like Biology, Chemistry, Physics, Earth Science, and Astronomy.
• Formal sciences deal with abstract concepts and theories, encompassing Mathematics, Logic, and Statistics.
• Social sciences explore human behavior and societies, including Psychology, Sociology, Anthropology, and Economics.

Scientific Method

• The scientific method is a systematic process for acquiring knowledge, consisting of the following steps:
  • Observation: Identifying a phenomenon or problem.
  • Question: Formulating a question based on the observation.
  • Hypothesis: Proposing an explanation or prediction for the observed phenomenon.
  • Experimentation: Testing the hypothesis through controlled experiments.
  • Analysis: Examining data collected from experiments.
  • Conclusion: Drawing conclusions based on data analysis.
  • Communication: Sharing results with the scientific community.

Characteristics of Scientific Knowledge

• Empirical: Scientific knowledge is based on observation and experimentation, meaning it is grounded in real-world evidence.
• Repeatable: Experiments must yield consistent results when repeated by different researchers, ensuring reliability of findings.
• Falsifiable: Hypotheses must be testable and potentially disproven, meaning they are open to challenge and refinement through evidence.
• Progressive: Scientific knowledge evolves over time with new discoveries and technologies, leading to a constant progression of understanding.

Types of Scientific Investigations

• Descriptive investigations focus on observing and describing the characteristics of a phenomenon.
• Comparative investigations compare two or more groups or conditions to identify differences and similarities.
• Experimental investigations manipulate variables to determine their effects on a particular outcome.

Importance of Science

• Science drives advancements in technology and medicine, leading to improved healthcare, communication, and transportation.
• It enhances our understanding of the universe, from the smallest particles to the vastness of space.
• Science plays a crucial role in addressing global challenges such as climate change, health crises, and resource management.
• Scientific evidence provides a basis for informed decision-making in policy, economics, and other areas of human endeavor.

Ethics in Science

• Ethical principles guide scientific research to ensure integrity, honesty, and responsible conduct.
• They include:
  • Integrity in data reporting: Accurate and truthful representation of research findings.
  • Honesty in research results: Avoiding fabrication or manipulation of data.
  • Respect for human and animal rights in experimentation: Ensuring ethical treatment of subjects and minimizing harm.
  • Transparency and reproducibility in studies: Making research methods and data accessible for verification and replication.
