What is Concentration?

Concentration is how much of something is mixed into another thing, like how many spoonfuls of sugar you put into your cereal.

Imagine you have a cup of juice. If you add just one teaspoon of sugar, the juice isn’t very sweet. But if you add five teaspoons, it’s super sweet. That's because the concentration of sugar is higher in the second case, there’s more sugar in the same amount of juice.

Think about playdough. If you mix a little red playdough into a big pile of white playdough, it won’t look very pink. But if you mix a lot of red playdough into the same amount of white playdough, it will look much more pink. That’s just like concentration, the more red playdough you add, the higher the concentration of red in your mixture.

So whether you're talking about juice, playdough, or even how many kids are in a classroom, concentration is all about how much of one thing there is compared to another. Concentration is how much of something is mixed into another thing, like how many spoonfuls of sugar you put into your cereal.
