Growing Crystals

Abstract

The Salt Project

The project that I did for my 2017-2018 science fair project is a thing that has to with converting salt into crystals. I’m trying to find out if different types of salt with make different types of salt crystals. My hypothesis is that they will make different crystals because they are all different types of salt.

First I had to gather all of my ingredients. I had to buy 4 different types of salts Himalayan pink salt, BBQ salt, Garlic salt, and the original table salt. After I did all of that ten I got a half of cup of water and poured it into a pan. I put the pan onto the bowl and turned on the oven. Later when the water was boiling I put in the salt and stirred it around for about 2 min. After I was done boiling the water I poured the water into a jar and tied a string to a pencil and put the pencil in the jar. I had to wait about 5-6 hours for the string to become a crystal.

For my first salt I did the Pink Himalayan salt. The first crystal was very bumpy and soft and it actually looked like a crystal. It measured to be about ⅕ inches wide. The next salt that I tested was the BBQ Salt. The salt was much more tiny than the Himalayan Pink Salt and it was much harder, but it was still soft. The salt was ⅙ wide. Next I did the Garlic Salt. This salt barely made any crystals and it was very very soft. It measured to be ¼ wide.

In the end my hypothesis was wrong because they all made different types of cool crystals. I learned that all salts are not the same thing and have their own special qualities. Some errors that I could have made an error while pouring the salt into the pan or putting to much water in. I could test more salts to improve this experiment.
