Understanding Scientific Theories and Laws

The video discusses the difference between casual and scientific use of the word 'theory'. It uses a personal story about earthworms to illustrate how hypotheses are formed. The video explains that scientific theories are well-supported by evidence and differ from casual theories. It also clarifies that scientific theories do not become laws, as they serve different purposes. The video concludes with a call to stay curious and offers further reading on earthworm behavior.
