Introduction to Science: Core Principles

• Science employs a systematic and organized approach to understand the natural world.
• Science achieves understanding through observation, experimentation, and analysis.
• The primary goal of science involves discovering and explaining natural phenomena.
• Science formulates theories and develops models to predict future events or behaviors.
• Objectivity and rigor in scientific investigations are ensured by relying on empirical evidence and the scientific method.
• Science includes a wide array of disciplines, like physics, chemistry, biology, astronomy, and environmental science.

Core Principles of Science

• Science values objectivity, minimizing personal biases and subjective interpretations.
• Science relies on empirical evidence, using observable and measurable data to support claims.
• Skepticism is vital, questioning assumptions and conclusions and requiring evidence-based justification.
• Reproducibility ensures experiments and observations can be repeated to verify results.
• Testability involves formulating hypotheses that can be tested through experimentation or observation.

The Scientific Method

• Observation involves identifying a phenomenon or problem of interest.
• Hypothesis formulation includes developing a testable explanation for the observed phenomenon.
• Prediction involves making forecasts based on the hypothesis.
• Experimentation requires designing and conducting experiments to test predictions.
• Analysis involves examining the data collected from experiments.
• Conclusion means interpreting results and drawing conclusions about the hypothesis.
• Communication entails sharing findings and results with the scientific community.

Major Branches of Science

• Natural sciences focus on studying the physical world.
  • Physics investigates the fundamental laws and principles governing matter, energy, space, and time.
  • Chemistry studies the composition, structure, properties, and reactions of matter.
  • Biology explores the study of living organisms, including their structure, function, growth, origin, evolution, and distribution.
  • Astronomy focuses on studying celestial objects, space, and the physical universe.
  • Earth science encompasses the study of the Earth's structure, composition, processes, and its history.
• Social sciences examine human behavior, society, and social relationships.
  • Psychology studies the human mind, behavior, and mental processes.
  • Sociology investigates human society, social interactions, and social structures.
  • Economics analyzes the production, distribution, and consumption of goods and services.
  • Anthropology explores the study of human cultures, societies, and their development.
  • Political science focuses on the theory and practice of politics, government, and political behavior.
• Formal sciences use formal systems to generate knowledge.
  • Mathematics deals with the study of numbers, quantities, shapes, and their relationships using logical reasoning.
  • Logic studies the principles of valid reasoning and inference.
  • Statistics involves the collection, analysis, interpretation, presentation, and organization of data.
  • Computer science focuses on the study of computation, algorithms, and information processing.

Scientific Theories and Laws

• A scientific theory is a well-substantiated explanation of some aspect of the natural world.
• Theories are based on facts repeatedly confirmed through observation and experimentation.
• A scientific law is a statement describing an observed pattern or relationship in nature, often expressed mathematically.
