Introduction to Science Concepts

What is Science?

• Science is a systematic and logical approach to understanding the natural world.
• It's a process of asking questions, gathering evidence, and developing explanations that can be tested.

Key Characteristics of Science

• Empirical: Science relies on observable evidence and data. Experiments and observations form the basis of scientific knowledge.
• Objective: Science strives to be impartial and free from personal bias. Results should be reproducible by others.
• Testable: Scientific explanations must be formulated in a way that can be tested through experiments or observations. If a hypothesis is not testable, it's not considered scientific.
• Replicable: Experiments and observations should yield the same results when repeated by different researchers. This ensures reliability and validity of the findings.
• Falsifiable: A scientific hypothesis or theory must be stated in a way that it could potentially be proven wrong. If something cannot be disproven, it may not be a scientific hypothesis.
• Parsimonious (or "Occam's Razor"): The simplest explanation that fits the evidence is usually favored.
• Tentative: Scientific knowledge is constantly refined and updated as new evidence emerges. Old theories are sometimes modified or replaced by better ones.

The Scientific Method

• A systematic approach used in scientific inquiry.
• Observation: Identifying a phenomenon worthy of study.
• Question: Formulating a specific question about the observation.
• Hypothesis: A testable explanation for the observed phenomenon.
• Prediction: A specific, measurable outcome expected if the hypothesis is correct.
• Experiment: A controlled procedure to collect data related to the prediction.
• Analysis: Evaluating the data collected in the experiment.
• Conclusion: Determining whether the data supports or refutes the hypothesis. If the hypothesis is not supported, scientists may reformulate the hypothesis or develop a new one.

Branches of Science

• Natural Sciences: Study of the natural world.
  • Physical Sciences: Focus on matter and energy (e.g., physics, chemistry, astronomy)
  • Life Sciences: Study of living organisms (e.g., biology, ecology, genetics)
• Social Sciences: Study of human behaviour and societies (e.g., psychology, sociology, economics)
• Formal Sciences: Deal with abstract concepts and structures (e.g., mathematics, logic)

Distinguishing Science from Non-Science

• Pseudoscience: Claims presented as scientific but do not adhere to the scientific method.
• Characteristics of Pseudoscience: Lack of falsifiability, reliance on anecdotal evidence, exaggerated claims, appeals to authority, lack of peer review, and use of vague language.
• Examples of pseudoscience include astrology, certain forms of alternative medicine that lack scientific backing, and some creationist views that conflict with established evolutionary biology.

Scientific Attitudes and Ethics

• Critical thinking: Evaluating information objectively and thoroughly.
• Curiosity: Maintaining an interest in understanding the world around us.
• Skepticism: Questioning claims and seeking supporting evidence before accepting them.
• Open-mindedness: Willingness to consider alternative hypotheses and interpretations.
• Integrity: Adhering to ethical principles in research and reporting findings.
• Honesty: Reporting results accurately.
• Transparency: Being clear about methods and data.

The Role of Models and Theories in Science

• Models: Simplified representations of complex systems or processes, allowing for easier understanding and prediction.
• Theories: Well-supported explanations of natural phenomena that unify a wide range of observations and experimental results. They are robust; the more robust a theory, the less likely it is to be drastically revised or overturned. Theories are highly likely to be accurate but are not absolute statements of absolute truth.
