A mixture in which substances are not evenly mixed. Heterogeneous mixture. In science, a heterogeneous mixture is one where you can see the different components, like a salad with various ingredients not blended together.
Imagine trying to fold a fitted sheet neatly; it often ends up looking lumpy and uneven. This scenario is similar to a heterogeneous mixture where the components are not evenly distributed. Just as the creases and folds in the sheet represent areas of differing concentrations of fabric, a heterogeneous mixture has pockets of different substances unevenly mixed, like the chocolate chips in a cookie.
