What is the difference between a law and a theory?

• A law explains "what" happens, while a theory explains "why" something happens.
• A law is based on evidence, while a theory is based on opinion.
• There is no difference- a law and a theory are the same thing.

Why do scientific ideas sometimes change?

• Scientific explanations must be supported by evidence. Explanations can change over time as new evidence is discovered.
• People are responsible for scientific ideas, and sometimes people change their minds and opinions as they get older.
• Scientific ideas will never change- they must always remain the same.
