The Scientific Method Quiz

Study Notes

The Scientific Method

Science is a systematic way of acquiring knowledge about the natural world through observation, experimentation, and the formulation of testable hypotheses.
The scientific method is a cyclical process. It starts with observations, leading to questions, which stimulate the formation of hypotheses, then tested through experiments.
The results of experiments are analyzed and conclusions drawn. These conclusions may confirm or refute initial hypotheses, leading to further observations, questions, and experiments.
Key elements of the scientific method include:
- Observation: systematic noting and recording of phenomena.
- Question: the formulation of a specific question based on observations.
- Hypothesis: a testable explanation or prediction about the relationship between variables.
- Experiment: a controlled procedure to test the hypothesis.
- Data collection & analysis: gathering and interpreting results.
- Conclusion: an explanation of the experimental results, confirming or refuting the hypothesis.
The scientific method promotes skepticism and critical thinking, ensuring new knowledge is supported by evidence.
Scientists use various tools and techniques to conduct investigations, depending on the research area and phenomena studied.

Scientific Theories

A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on facts repeatedly confirmed through observation and experiment.
Theories are comprehensive frameworks explaining many related phenomena, not just guesses or hypotheses.
Theories are constantly refined and revised as new evidence emerges.
A robust theory explains known facts, makes accurate predictions, and aligns with other established theories.
Examples of scientific theories include the Theory of Evolution and the Theory of Relativity.

The Nature of Science

Science is an ongoing process of investigation and discovery, not a fixed set of truths.
Scientific knowledge is always subject to revision and improvement as new evidence emerges.
Science relies on empirical evidence, meaning knowledge is based on observation and experiment.
Science is characterized by objectivity, minimizing bias.
Science spans many disciplines, including biology, chemistry, physics, and environmental science.
Scientific knowledge is based on reasoning, evidence, and repeated experiments, not beliefs, opinions, or faith.

Scientific Laws

A scientific law describes a consistently true relationship in nature.
Laws explain how phenomena occur, but not why.
Laws are concise statements, often mathematical, summarizing observed data.
Scientific laws are highly reliable, supported by vast evidence, and predict occurrences under specific conditions.
Examples of scientific laws include the Law of Gravity and the Law of Conservation of Energy.
Scientific laws and theories are distinct yet complementary.

Scientific Measurement

Precise and accurate measurement is crucial in scientific investigation.
Measurement quantifies a property using standard units.
Significant figures indicate the accuracy of a measurement.
Scientific instruments and tools are essential for precise measurement.
Minimizing measurement errors requires proper handling and calibration of equipment.
