Summary
A process of asking a question, forming a hypothesis, testing it with experiments and drawing conclusions.
In depth
Steps: observation, question, hypothesis, prediction, experiment, analysis, conclusion and communication. Science is iterative and uses peer review. A good hypothesis is falsifiable (Popper). Theories are well-supported explanations; laws describe regularities.
The scientific method is not a rigid sequence; discoveries may begin with chance observation. Peer review, replication and transparency give science self-correction.
Common mistake: a theory is not 'just a guess'; it is a well-supported explanation.
The scientific method is a systematic way of finding reliable explanations. A typical cycle is observation, question, background research, hypothesis, prediction, controlled experiment, analysis, conclusion and communication, with results prompting new questions.
Real science is not a strict recipe: ideas come from curiosity, modelling and chance observations (such as Fleming's mould), and many studies are descriptive or comparative rather than experimental. Findings are shared through peer review so that others can check and repeat them. Theories are well-tested explanations that unify many observations, not guesses.
Example: Pasteur's swan-neck flasks tested the hypothesis that microbes arise from other microbes.
Key idea: a hypothesis must be falsifiable, so evidence can show it wrong.
Frequently asked questions
What is Scientific Method?
A process of asking a question, forming a hypothesis, testing it with experiments and drawing conclusions.
Which area of biology covers Scientific Method, and how advanced is it?
Scientific Method is one of the 51 topics in Lab Methods & Biostatistics. It is rated Beginner, so it suits learners who are starting out in biology. Related topics in this area include Hypothesis, Reliability and Validity, Reproducibility in Science.
Can you give an example of Scientific Method?
Pasteur's swan-neck flask experiments refuted spontaneous generation.
What should I learn before Scientific Method?
Scientific Method is a Beginner topic, so no earlier topic is required. Other Beginner topics in Lab Methods & Biostatistics that pair well with it include Hypothesis, Variables, Control Group.
What topics are related to Scientific Method?
The closest topics to Scientific Method are Hypothesis, Reliability and Validity, Reproducibility in Science, Statistical Power. Comparing them side by side is a good way to see how the ideas connect.
How can I check that I understand Scientific Method?
Read the summary and the in-depth section, then use the quick check on the interactive lesson for Scientific Method. To practise the whole of Lab Methods & Biostatistics, use the Lab Methods & Biostatistics quiz.
How is Scientific Method different from Hypothesis?
Scientific Method: A process of asking a question, forming a hypothesis, testing it with experiments and drawing conclusions. Hypothesis: A testable explanation for an observation that can be supported or refuted by evidence. Read both side by side and note what each one explains.
What is a common mistake about Scientific Method?
A theory is not 'just a guess'; it is a well-supported explanation.
How should I study Scientific Method step by step?
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Hypothesis and explain the difference aloud. Finally, take the Lab Methods & Biostatistics quiz and come back to this page for any question you miss.
