Our+Crystal+Structure+Experiment

toc =Salt Experiment - Scientific Method=

Purpose
Tell the difference between rocks and minerals using the crystal structure.

Hypothesis
Our hypothesis states that the salt crystals would dry up and the water would still be a liquid.

Materials

 * a paper plate
 * one silver spoon
 * one plastic spoon
 * hot water
 * table salt (sodium chloride)
 * two Popsicle sticks
 * two small paper cups
 * blue scotch tape

Procedure
First, you tape the silver spoon and the plastic spoon to the paper plate. Next, you mix the table salt with the hot water with the Popsicle sticks to make a solution. Then, you pour the solution of water and salt into the two spoons that you taped onto the plate.You have to wait about a week until you start observing your experiment.

Data/Observation
As we were observing our salt crystals, we found a little bit of a brown spot. We think someone might have dropped a type of food in it, such as trail mix or noodles with sauce on it.

CER (claim, evidence, reasoning)
What happened with the actual experiment was that the water evaporated leaving small salt crystals behind, thus showing us the crystal structure.
