Answer:
Have you ever mixed together salt and sand? It is fun to see how all of those tiny grains of salt and sand mix together! But what if you had to separate them out again? Do you have nightmares of tiny tweezers, a magnifying glass, and hours spent picking grains of salt and sand apart? Do not be afraid, there is another way! In this chemistry science project you will use the differences in solubility between salt and sand to find out the simple "solution" to this problem.
