Let’s Begin…

Chat with a friend about an established scientific theory, and she might reply, “Well, that’s just a theory.” But a conversation about an established scientific law rarely ends with “Well, that’s just a law.” Why is that? What is the difference between a theory and a law... and is one “better”? Matt Anticole shows why science needs both laws and theories to understand the whole picture.

The following were once accepted theories but scientists eventually replaced them with better theories. Learn a bit more about one of them and find out why they didn’t make the cut! Write a five sentence paragraph about the one you chose. a. Alchemy b. The heliocentric model c. Spontaneous generation d. The interstellar aether
