Scientific Method: Salt Crystal Experiment

 * 1) **Problem/Purpose/Question:** To understand the difference between a rock and a mineral.
 * 2) **Hypothesis:** We predict that the salt mixture will turn into salt crystals.
 * 3) **Materials:** Two plastic spoons, two pieces of duct tape, two magnifying glasses, two wooden mixers, two paper cups, hot water, table salt, rocks, and minerals.
 * 4) **Procedure:**
 * 5) Boil water
 * 6) Put table salt into water
 * 7) Fill half in both cups
 * 8) Pour water into both, each two-thirds of the spoon[[image:JBKR2.jpg caption="Water fills up 2/3 of the spoon's capacity."]]
 * 9) Let mixture sit for one day
 * 10) Examine spoon the next day
 * 11) **Data/Observation:** The salt crystals were in the spoon. [[image:JBKR.jpg width="219" height="103" caption="How the salt the finished experiment looks like."]] Though they were not a perfect square, they resembled salt crystals.
 * 12) **CER (Claim, Evidence, Reasoning):** Claim: The salt was not visible in the mixture, but was in it. Evidence: The salt dissolved into the water, making a mixture. Reasoning: The salt dissolved into the water, so it could not become into a different substance. This was visible through the salt crystals, because the water evaporated and the salt was reformed and left behind.
