Scientific knowledge is gained through questioning and testing, and is always subject to revision based on new evidence. What is the first step in the scientific method?
The first step is observation, where information is collected using senses or instruments. How do quantitative and qualitative observations differ?
Quantitative observations involve values or numbers, while qualitative observations describe appearance or qualities. What is a hypothesis in the context of the scientific method?
A hypothesis is a proposed and testable explanation for an observation. What distinguishes a scientific theory from a hypothesis?
A theory is a broad, testable hypothesis supported by a large body of evidence, while a hypothesis is a specific, testable explanation. What is a scientific law?
A scientific law is a testable phenomenon that has been proven true by the scientific community. Can hypotheses and theories be proven correct?
No, hypotheses and theories cannot be proven correct; they can only be falsified. What happens if experimental results do not support the hypothesis?
If results do not support the hypothesis, the hypothesis is rejected and the process starts over with a new observation. What is the purpose of peer review and publishing in the scientific method?
Peer review and publishing allow other scientists to evaluate and validate the results, contributing to scientific knowledge.
