Scientific Method Overview

Scientific Method

• Science is a systematic process for understanding the natural world.
• It involves observation, questioning, experimentation, and analysis.
• The scientific method is a framework for conducting scientific inquiry.
• The goal of science is to explain natural phenomena and predict future events.

Types of Science

• Natural sciences: Study the natural world, including physics, chemistry, biology, and geology.
• Social sciences: Study human behavior and society, including psychology, sociology, and economics.
• Formal sciences: Study abstract concepts, including mathematics and logic.

Scientific Reasoning

• Deductive reasoning: Starts with a general premise and applies it to specific cases. A logical conclusion follows.
• Inductive reasoning: Starts with specific observations and draws general conclusions. Generalizations from specific evidence.

Scientific Inquiry

• Observation: Careful examination of the natural world.
• Questioning: Formulating specific questions about observations.
• Hypothesis: A proposed explanation for an observation.
• Experimentation: Testing a hypothesis to see if it explains the observation.
• Analysis: Examining the results of an experiment to determine if the hypothesis is supported.
• Conclusion: Drawing a conclusion that supports or refutes the hypothesis.
• Communication: Sharing the results and process of scientific inquiry with the wider community.

Scientific Theories and Laws

• Scientific theory: Well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.
• Scientific law: Description of a natural phenomenon or relationship that consistently occurs under certain conditions. It describes what happens but not why.

Scientific Principles

• Objectivity: Scientists strive to be objective and unbiased in their work, avoiding personal biases.
• Reproducibility: Scientific findings should be reproducible by other scientists.
• Falsifiability: A scientific hypothesis must be testable and potentially disproven.

Scientific Attitudes

• Curiosity: Desire to ask questions and explore the unknown.
• Skepticism: Questioning claims and seeking evidence.
• Open-mindedness: Accepting new ideas and considering alternative perspectives.
• Perseverance: Continuing to seek answers even when faced with challenges.

Scientific Measurement

• Accuracy: Closeness of a measurement to the true value.
• Precision: Closeness of repeated measurements to each other.
• Significant figures: Indicate the precision of a measurement.
• Units of measurement: Standard units for quantities, like meters for length.

Scientific Ethics

• Honesty and integrity: Maintaining accurate records and avoiding fraud.
• Plagiarism: Avoiding presenting others' work as one's own.
• Conflicts of interest: Avoiding situations where personal interests could compromise objectivity.
• Respect for intellectual property: Acknowledge sources and avoid infringing on others' work.
