Introduction to Scientific Method and Branches of Science

Scientific Method

• Science is a systematic approach to understanding the natural world.
• It relies on observation, experimentation, and the formulation and testing of hypotheses.
• Steps in the scientific method include: observation, question formation, hypothesis development, prediction, experimentation, analysis, and conclusion.

Branches of Science

• Science is broadly categorized into several branches, including:
  • Physical Sciences: physics, chemistry, astronomy, and related fields.
  • Biological Sciences: biology, zoology, botany, and related fields.
  • Earth Sciences: geology, meteorology, oceanography, and related fields.
  • Social Sciences: psychology, sociology, economics, and related fields.

Scientific Laws and Theories

• Scientific laws describe relationships in nature.
• They are usually expressed as mathematical equations or statements that explain observed phenomena. Examples include Newton's Laws of Motion and the Law of Conservation of Energy.
• Scientific theories explain how and why natural phenomena occur.
• They are based on extensive observation, experimentation, and evidence. They are models that explain a vast body of data and observations. Unlike laws, theories are not absolute truths and can be modified as new evidence emerges.

Scientific Inquiry

• The process of scientific inquiry involves posing questions, developing hypotheses, designing experiments, analyzing data, and drawing conclusions.
• Key aspects of scientific inquiry include: critical thinking, skepticism, objectivity, and reproducibility.
• Accurate record keeping, appropriate use of controls and variables, are essential for reliable results.

Scientific Measurement

• Scientific measurements are crucial for data collection and analysis.
• Units of measurement and standards are essential for accuracy.
• Measurements are affected by uncertainties due to precision limitations, instrument biases, and environmental factors.
• Using appropriate units and expressing measurements with uncertainty are crucial in accurate data presentation.

Scientific Communication and Collaboration

• Communication is essential in science for sharing findings and ideas.
• Peer review of scientific publications ensures quality control and validity of research.
• Collaboration between scientists across disciplines promotes progress.

The Nature of Science

• Science is a process, not a set of facts.
• It is characterized by skepticism, curiosity, and a desire to understand the natural world.
• Science constantly evolves as new evidence and insights emerge.
• The scientific enterprise depends on integrity, objectivity and ethical conduct.
• Science builds on its past discoveries and often involves making logical deductions from existing knowledge and theories and constructing models from experimental processes.
• Science is not static; it evolves and changes based on new discoveries.
