Suppose that you dissolved a teaspoon of sugar within a warm glass of water and stirred its contents until no more solid sugar was observed. Once the sugar solution appears clear and colorless, we have created an example of a homogeneous mixture. The concentration of sugar within this solution would be constant throughout.

Heterogeneous Mixtures – These are mixtures which are not uniform in appearance. The concentration of substance(s) within such a mixtures is not constant throughout the mixture. Each constituent substance is not distributed evenly. Suppose that you emptied a bag of assorted nuts, candy, and popcorn into a basket.
