When you add some solids to water, they dissolve and seem to disappear. But other solids sink to the bottom and can still be seen and separated from the water. Why? Click here to watch the video that introduced this lab.
My first grade chemists continued their study of matter by pouring salt, pepper, jello, flour, sugar, and oats in water to determine if they would make a suspension or a solution. We completed a lab report as we worked.
This is a great lab to extend at home. Try mixing other solids and liquids that you have in your pantry or refrigerator with water. Did you make a solution or a suspension?
