SC.912.N.1.3-Recognize and explain the difference between theories and laws and give several examples of scientific theories and the evidence that supports them.

2. A scientist performs an experiment to see if acids have an effect on the health of a particular type of plant. Three sets of plants were treated with acidic solutions of known pH while the control set was treated with a solution of neutral pH 7.

6. Theories vs. Laws
Theories: An explanation for why natural events occur developed from extensive observations, experimentation, and reasoning.
LAWS: A scientific principle that states what occurs during a natural event developed from extensive observations and experimentation.

7. BILLY PASSED A TEST. SORT THESE as a Law or Theory!
I passed because I studied for two hours and got a good night's sleep.
I got a 94% score, and missed the questions about gravity.
Replace with Science based examples.

8. LAW: I got a 94% score, and missed the questions about gravity. - WHAT
Why!
