Science Experiment: Saturated Solution

When a saturated solution such as salt water is cooled, salt crystals form.

Things needed:
1. A small pan that holds about 1 or 2 cups of water
2. About one-third cup of water
3. About 1 cup of salt
4. A piece of string
5. A paper clip
6. A pencil or stick
7. A beaker

Step 1: Place about one-third of a cup of water in a small pan.
Step 2: Bring the water to boil. Pour the water into a beaker.
Step 3: Stir in the salt until no more can be dissolved. You now have a saturated solution.
Step 4: Suspend a paper clip on a string and let it dangle down in the salt solution. As the saturated solution cools, salt crystals will form on the paper clip.

Chemistry & Biology : How to Make Salt Crystals
Salt crystals are created through a simple process that involves boiling water, measuring out salt until it no longer dissolves in water, and suspending a paper clip or ring a couple of centimeters above the bottom of the container.
