Test: Scientific Method
20 questions
Question 1: Once a scientific theory is accepted, it becomes a totally indisputable fact and cannot be modified or discarded by new evidence.
A. Yes
B. No
Explanation: The study materials state that theories 'never become totally indisputable fact'. It also explains that if 'new evidence comes along that can't be explained using the existing theory, then the hypothesising and testing is likely to start all over again', which implies the theory may need to be modified or scrapped.
Question 2: Accepted scientific theories represent the ultimate and unchanging truths in science, with no possibility of future modification or rejection.
A. Yes
B. No
Explanation: The study materials state that 'theories never become totally indisputable fact' and that 'if new evidence comes along that can't be explained using the existing theory, then the hypothesising and testing is likely to start all over again.' This indicates that theories are not ultimate or unchanging truths and can be modified or even scrapped.
Question 3: Peer-review involves other scientists checking that experiments have been done in a sensible way before findings are published.
A. Yes
B. No
Explanation: The study materials state that 'Peer-review is where other scientists check results and scientific explanations to make sure they're 'scientific' (e.g. that experiments have been done in a sensible way) before they're published'.
Question 4: Is the reproduction of original experiments by other scientists primarily done to develop new predictions, rather than to check the results?
A. Yes
B. No
Explanation: Other scientists try to reproduce original experiments to check the results. While they also base their own predictions on the hypothesis and carry out their own experiments, the act of reproducing the original experiments is specifically for verification.
Question 5: The scientific method has developed over time with contributions from many individuals.
A. Yes
B. No
Explanation: The study materials explicitly state, "The scientific method has developed over time, and many people have helped to develop it."
