Homogeneous = food coloring, mouthwash, green ink, and cooking oil Homogeneous means that is is the same throughout like pure liquid water. Heterogeneous = ice cubes (however when they melt it will be homogeneous) , mashed unmashed potatoes, cc ice cream, and cake batter. Heterogeneous means that it is not the same throughout like water and oil in the same glass. Since oil does not dissolve in water or vice versa this is a heterogeneous mixture.

granite: heterogeneous, because it is made up of different minerals (felspars, mica, quartz, etc) , unlike iron ore or quartz which are made of, well: iron oxide and quartz only

Try looking up pictures of them on google or something. Hetero mixtures are probably easier to spot.
