Bellringer- 8-27-18 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.

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. Bellringer 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. Which is the best conclusion for this experiment?  A. Acid has no effect on the health of this type of plant. B. High acidity is helpful to this type of plant. C. Low acidity is harmful to this type of plant. D. High acidity is harmful to this type of plant.

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.

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.
