Systematic Approach to Science

Science: A Systematic Endeavor

• A systematic and organized approach to understanding the natural world is achieved through observation, experimentation, and analysis.
• Science involves a dynamic process of inquiry.
• The inquiry process builds and organizes knowledge creating testable explanations and predictions.
• Science relies on empirical evidence, logical reasoning, and skepticism.
• These tools refine and improve our understanding of the universe.

Core Principles of Science

• Objectivity minimizes bias in observations and interpretations.
• Empiricism relies on evidence from observation and experimentation.
• Skepticism questions claims, demanding supporting evidence.
• Testability formulates hypotheses that experimentation or observation can test.
• Falsifiability ensures scientific theories can be proven wrong by evidence.
• Repeatability is when scientific findings are reproducible by other researchers.

Scientific Method

• The scientific method is a systematic approach used to investigate phenomena.
• It's used to acquire new knowledge.
• It's used to correct and integrate previous knowledge.
• Observation identifies a question or problem.
• Hypothesis formulates a testable explanation or prediction.
• Experimentation conducts controlled tests to gather data.
• Analysis identifies patterns or relationships in data.
• Conclusion draws conclusions based on evidence determining if the hypothesis is supported or refuted.
• Communication shares findings through publications and presentations.

Branches of Science

• Natural Sciences study the physical world.
  • Physics examines the universe's fundamental constituents, their interactions, and governing laws.
  • Chemistry studies matter's composition, structure, properties, and reactions.
  • Biology investigates living organisms, their functions, evolution, and environmental interactions.
  • Earth Science encompasses the study of Earth's structure, composition, processes, and history.
  • Astronomy focuses on celestial objects, the universe, and its evolution.
• Social Sciences study human behavior and societies.
  • Sociology examines social structures, interactions, and institutions.
  • Psychology studies the mind, behavior, and mental processes.
  • Economics analyzes the production, distribution, and consumption of goods and services.
  • Anthropology explores human cultures, societies, and their development.
  • Political Science investigates systems of government, political behavior, and public policy.
• Formal Sciences are disciplines concerned with formal systems.
  • Logic studies the principles of valid reasoning and inference.
  • Mathematics focuses on abstract structures, relationships, and patterns.
  • Theoretical Computer Science explores the theoretical foundations of computation and information processing.
• Applied Sciences apply scientific knowledge to practical problems.
  • They can develop new technologies.
  • Engineering uses scientific principles to design and build structures, machines, and systems.
  • Medicine applies scientific knowledge to diagnose, treat, and prevent diseases.
  • Agriculture uses scientific methods to improve crop production and livestock management.
  • Computer Science develops computer systems, software, and algorithms.

Scientific Theories and Laws

• Scientific Theory provides a well-substantiated explanation of the natural world.
  • It can incorporate facts, laws, inferences, and tested hypotheses.
  • Examples include the theory of evolution by natural selection, and the theory of general relativity.
• Scientific Law is a descriptive statement or equation.
  • It reliably predicts events under certain conditions.
  • Examples include Newton's law of universal gravitation, and the laws of thermodynamics.

Measurement and Units

• Science relies on precise measurements to quantify observations and experiments.
• The International System of Units (SI) is the standard measurement system in science.
  • Length is measured in meters (m).
  • Mass is measured in kilograms (kg).
  • Time is measured in seconds (s).
  • Electric Current is measured in Amperes (A).
  • Temperature is measured in Kelvins (K).
  • Amount of a Substance is measured in Moles (mol).
  • Luminous Intensity is measured in Candelas (cd).

Tools and Technologies

• Scientists use tools and technologies to conduct research and gather data.
• Microscopes magnify small objects for detailed observation.
• Telescopes observe distant objects in space.
• Spectrometers analyze matter's composition by studying its interaction with light.
• Particle Accelerators accelerate subatomic particles to high speeds for interaction studies.
• Computers are used for data analysis, modeling, and simulations.

Scientific Communication

• Scientists communicate findings to share knowledge.
• Peer-Reviewed Journals are scientific publications reviewed by field experts.
• Conferences are meetings where scientists present research and engage in discussions.
• Books and Textbooks provide summaries of scientific knowledge.
• Websites and Online Resources disseminate scientific information.

Ethics in Science

• Ethical conduct is essential in scientific research.
• Integrity, honesty, and responsible practices are necessary.
• Informed Consent requires voluntary agreement from research participants.
• Data Integrity ensures data accuracy and reliability.
• Conflict of Interest requires disclosing potential biases.
• Animal Welfare requires treating research animals humanely.
• Responsible Authorship gives proper credit to all research publication contributors.
