Which of the following is a valid reason why a scientist might reject a scientific theory?

• Some people disagree with it.

• It covers too broad of a topic.

• We learn new information that contradicts it.

• It is too old.

Why is it important that scientists modify scientific theories when important new information is discovered?

• to confuse other scientists

• to keep the theory interesting and fresh

• to keep the theory as accurate and effective as possible

• to make sure the general public does not understand the theory

Why is it important that scientists modify scientific theories when important new information is discovered?

What is a scientific theory?

• A well-tested explanation for a wide range of observations

• A guess based on limited information

• An opinion held by scientists

Why might a scientific theory be changed?

• To make it more popular

• Because new evidence contradicts it

• To align with public opinion

• To simplify it

Which of the following is an example of a scientific theory?

• The theory of gravity

• The hypothesis of evolution

• The opinion of relativity

What happens when new evidence is found that contradicts a current theory?

• The theory is immediately discarded

• The theory is modified to incorporate the new evidence

• The evidence is ignored

• The theory is proven wrong
