A heterogeneous mixture is one whose components are visually distinguishable from each other. This is usually due to the fact that the particles sizes of the components in a heterogeneous mixture are much larger. Suspensions (like sand stirred up in water) scatter light and will eventually settle out. A salad and a bag of mixed coins could also be considered a heterogeneous mixture, since the components are visually distinguishable and easily separated.

A bowl of Fruit Loops cereal is a heterogeneous mixture because it has cereal bits of many colors floating around in milk.
A bottle of balsamic vinaigrette salad dressing is a mixture that is heterogeneous, and has to be shaken up to make the mixture appear and taste more combined.
Sand shaken up in a bottle of water is a heterogeneous mixture of sand particles floating around which will eventually settle to the bottom of the bottle, making it look a lot less like a mixture. Mixed nuts is a type of heterogeneous mixture that can be separated simply by pouring them onto a table and sorting them into separate piles, each of the same nut.
Pizza is a heterogeneous mixture of dough, sauce, cheese, and other toppings.
A bowl of oatmeal with raisins is a heterogeneous mixture.
A salad with lettuce, cheese, seeds, tomatoes, broccoli, and other vegetables is an example of a heterogeneous mixture. A bowl of candy like M&Ms, Skittles, or jelly beans is a heterogeneous mixture, with a non-uniform variety of colors and flavors represented in a single bowl.
Vinegar and oil are often mixed together as a condiment, but the mixture itself is heterogeneous. They may stay together for a while, but they’re sure to be broken apart after a while.
You will encounter many of these types of heterogeneous mixtures every day not just in scientific labs but in the real world.
