Scientific Law and Theory

Scientists create both scientific theories and scientific laws as they make observations and conduct experiments about the natural world. Which of the following statements most accurately compares the difference between scientific theories and scientific laws?

• Scientific laws are based on evidence, while scientific theories are not.

• Scientific theories involve only biology, while laws involve all types of science.

• Scientific theories involve mathematical equations, while scientific laws are based on observations.

• Scientific theories are ideas that explain natural events, while scientific laws more reliably predict natural events.

Which of these can change when new evidence is presented?

• theory

• law
