Introduction to Science Quiz

Introduction to Science

• Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
• It relies on empirical evidence, which is obtained through observation and experimentation.
• Science aims to understand the natural world through a process of inquiry.

Branches of Science

• Natural sciences study the natural world and encompass various disciplines, including:
  • Physics: Studies matter, energy, and their interactions.
  • Chemistry: Studies the composition, structure, properties, and reactions of matter.
  • Biology: Studies living organisms and their interactions.
  • Earth science: Studies the Earth's structure, processes, and history.
  • Astronomy: Studies celestial objects and phenomena.
• Social sciences investigate human behavior and societies, such as:
  • Psychology: Studies mental processes and behavior.
  • Sociology: Studies human social behavior and societies.
  • Economics: Studies production, distribution, and consumption of goods and services.
  • Political science: Studies political systems and behavior.
  • Anthropology: Studies human societies and cultures.
• Formal sciences utilize abstract structures and mathematical systems, including:
  • Mathematics: Studies quantity, structure, space, and change.
  • Logic: Studies the principles of valid reasoning.
  • Computer science: Studies information and computation.

Scientific Method

• The scientific method is a systematic approach to understanding the natural world.
• It involves several key steps:
  • Observation: Noticing a phenomenon or pattern.
  • Questioning: Formulating a question about the observed phenomenon.
  • Hypothesizing: Proposing a possible explanation or prediction (the hypothesis) for the phenomenon.
  • Experimenting: Designing and conducting experiments to test the hypothesis.
  • Analyzing results: Evaluating the data from the experiment.
  • Interpreting results: Drawing conclusions from the analysis.
  • Revising or accepting: Adjusting the hypothesis or developing new ones based on the results.

Key Concepts in Science

• Theory: A well-substantiated explanation of some aspect of the natural world, supported by a large body of evidence.
• Law: A concise statement or mathematical equation that summarizes a vast body of observations about a specific phenomenon or relationship.
• Variables: Factors that can be changed or measured in an experiment.
  • Independent variable: The factor that is manipulated by the researcher.
  • Dependent variable: The factor that is measured to see how it is affected by the independent variable.
  • Controlled variables: The factors that are kept constant throughout the experiment.
• Empirical evidence: Data obtained through observation and experimentation, it forms the foundation of scientific knowledge.
• Reproducibility: Experiments should be repeatable by other scientists with similar results obtained, lending credence to findings.
• Peer review: A process where scientists critically evaluate each other's work before publication to ensure quality and validity. This process helps maintain high standards in scientific research & publication.
• Models: Simplified representations of complex phenomena or structures that help us visualize and understand them.
• Models in science can be physical, mathematical, or conceptual.

Importance of Science

• Science provides a framework for understanding the natural world and its processes.
• It enables technological advancements and innovations that improve human life.
• It helps us address global challenges such as climate change, disease, and food security.
• It fosters critical thinking, problem-solving skills, and a deeper understanding of the world around us.
• Scientific inquiry promotes questioning, evaluation, and constant refinement based on evidence.
