Some are:
-laws tell how
- laws are proven true
- Theories attempt to explain
- Theories are developed based on likely true things, but not necessarily proven
- hypothesis is an educated guess
- hypothesis is made before your test/experiment.
- laws are formed after tests and experiements.
- Theories are often based off of tests/experiment, but again, not necessarily proven to be true.
