TED-ED: What's the difference between a scientific law and theory? - Matt Anticole

The video explains the difference between scientific theories and laws, highlighting that laws predict outcomes while theories explain why things happen. It discusses how theories and laws evolve, using Kepler's work as an example. The acceptance of theories is competitive, with the best explanations prevailing. Even incorrect theories contribute to scientific progress. The video emphasizes that both laws and theories are essential for a comprehensive understanding of science.

What is the primary role of a scientific law?

• To provide a universal instruction manual

• To predict the results of certain conditions

• To challenge existing theories

• To explain why things happen

How did Johannes Kepler contribute to our understanding of planetary motion?

• By confirming the geocentric model

• By discovering the interstellar ether

• By developing laws of planetary motion

• By proving the theory of gravity

What is a key factor in the acceptance of a scientific theory?

• Its alignment with existing laws

• Its age and historical significance

• Its ability to predict new phenomena

• Its resistance to change

Which of the following is an example of a theory that was eventually discarded?

• The geocentric model

• The theory of relativity

• The theory of evolution

• The theory of gravity

Why are incorrect theories still valuable in science?

• They confirm existing beliefs

• They are never valuable

• They provide entertainment

• They can lead to new discoveries

What does the vulnerability of a scientific theory to new explanations indicate?

• Its potential for becoming dogma

• Its strength

• Its irrelevance

• Its weakness

How do scientific laws and theories complement each other?

• Both explain why things happen

• Both predict what happens

• Theories explain why, and laws predict what happens

• Laws explain why, and theories predict what happens
