Scientific Method

 * PROBLEM/PURPOSE/QUESTION :** The purpose of this experiment is to find out the differences between rocks and minerals.
 * MATERIALS :** These are the materials we used to conduct the experiment:
 * 2 SPOONS
 * 2 POPSICLE STICKS
 * PAPER PLATE
 * TAPE
 * SALT
 * 2 PAPER CUPS
 * BOWL
 * WATER
 * PROCEDURE :** These are the steps we used to conduct the experiment.

Popsicle-sticks until the salt dissolves.
 * 1.** First, using the bowl, boil water.
 * 2.** Then, pour the boiled water into the paper cups.
 * 3.** Pour, a spoon of salt into each of the paper cups and stir with the
 * 4.** Meanwhile, tape the two spoons onto either sides of the paper plate.
 * 5.** Next, lightly pour the salt water in the paper cups onto the spoons.(only fill the spoons only 3/4 of the way)
 * 6.** Let the water on the spoons sit for a day or two.
 * 7.** Now make a hypothesis. what do you think will happen?




 * HYPOTHESIS :** Our prediction is that the halite solution on the spoons will crystallize once the water evaporates.Evaporation is a thermal separation process.Once the water on our spoons became water vapor it left the crystals of the halite solution.

We observed that the halite solution left behind several crystals.Some crystals had a shape of a diamond and some crystals were plainly in an irregular shape.
 * DATA/OBSERVATIONS :**

Sodium chloride commonly referred to as salt is a compound. It is made up of two different kinds of atoms : one sodium atom and one chlorine atom.Joined together, these two atoms make one molecule of salt.Salt comes in many shapes.Refined salt or commonly called table salt is fairly regular in shape.Salt assembles to form salt crystals.Salt crystals form as salt molecules arrange themselves while the water evaporates.The bonds between the salt molecules are strong enough to squeeze out the water and arrange themselves to form a crystal.

Making Predictions

 * **Rock
 * || **Properties** || **Color** || **R/M** || **Observation** ||
 * #1 || has crystals, coarse || milky white || mineral || has a crystal structure ||
 * #2 || fairly smooth || tan, brown || rock || is sedimentary ||
 * #3 || shiny luster, has layers || black with yellow stripes || mineral || breaks easily,probably mica ||
 * #4 || has holes, hard, acute luster || gray-black || rock || metamorphic, has layers of air bubbles ||
 * #5 || made of different rocks || tan, shade of red || rock || very rough, probably granite ||
 * #6 || shiny luster || smooth black || rock || silky texture, possibly obsidian ||
 * #7 || very light || grainy || rock || light in weight/airy fiber-sedimentary probably pumice ||
 * #8 || rough, coarse || red, tan, gray || rock || conglomerate, sedimentary ||
 * #9 || grainy, flaky || tan, white || rock || looks like oatmeal metamorphic ||
 * #10 || fairly smooth || light brown/brown-orange || rock || probably a metamorphic rock ||
 * #11 || grainy || reddish, dull-ish || rock || a rough layered, probably sedimentary rock ||
 * #12 || kind of smooth || gray || rock || dented, maybe sedimentary ||
 * #13 || shiny on top layers || gray-white || rock || layered sedimentary rock ||
 * #14 || visible crystals, shiny || white || mineral || has crystal structure, conglomerate ||
 * #15 || shiny and rough || gray || rock || coarse metamorphic rock ||
 * #16 || rough and dull || strong gray || rock || a thinner version of rock sample #12 ||
