Try this experiment to learn what is and is not a solution. Fill the jars about half-full of water. Add a spoonful of salt to one jar and a spoonful of dirt to the other. Stir both and look at the water with your magnifying glass. The salt molecules dissolved into the water.
Salt is soluble in water.
The dirt molecules do not dissolve. Through your magnifying glass, you can see that the pieces of dirt are suspended in the water, not dissolved. This is called a suspension, not a solution. That s right. After some time, the dirt particles will settle on the bottom of the jar.
