A saturated solution is when the solute can dissolve in the solvent. For example, if you have a bottle of water and you pour lemonade crystals into the water, and it dissolves, the solution is saturated,

A supersaturated solution is when you pour the solute into the solvent and the solute doesn't dissolve. For example, if you have cup of iced tea, and you pour sugar into the tea, it is supersaturated when the sugar settles on the bottom of the glass. If you were to take the ice out of the tea, the sugar could then dissolve.

An unsaturated solution is when the solute CANNOT dissolve into the solvent. For example, if you have a glass of water, and you pour something like vegetable oil into it, it will not dissolve. So that makes the solution unsaturated
