**__ Scientific Method __**
I. Difference between a rock and a mineral II. Prediction/ Hypothesis- We think that the water will evaporate, leaving the crystals from the table salt behind. We also think that the crystals will be in the form of squares and/or rectangles. III. Materials- · 1 piece of masking tape/ duck tape · 1 paper plate · 2 plastic spoons · 5 mixing sticks (2 needed and 3 extra (opt) just in case they are needed) · 2 paper cups · 4 magnifying glasses · a couple dashes of table salt · a pot (to boil water in) · enough water to fill 2 small cups or however many cups there are IV. Procedure- Boil water and pour it into each paper cup which should both be each filled with table salt. Use a mixing stick (1 for each cup) to stir both mixtures until you can no longer see the grains of salt. Then, using the masking/duck tape, tape the two (2) spoons on opposite sides of the plate so that both of the spoons’ handles face/stick outside of the paper plate. After that, you fill only 2/3’s of both spoons with the mixture of boiling water and table salt. Let it sit for at least 24 hours. (To get the best results, let is sit undisturbed) V. Data/Observations- Salt crystals formed in the spoons. They formed in the shape of squares or rectangles. A perfect square actually formed in one of the spoons. VI. C.E.R.- We found out that all of the crystals form in different shapes. Salt happens to form in the shape of a rectangle or a square.
