1) The document describes an activity where students are grouped and given various solid samples like sugar, coffee, powdered milk etc to dissolve in water. 2) When the solids are mixed with water, some dissolve forming homogeneous mixtures called solutions, while others do not and remain heterogeneous mixtures. 3) Solutions have various uses - for example, sugar solution is used as a sweetener in drinks and foods, while salt solution is used to flavor and preserve foods. Solutions are homogeneous mixtures that appear uniform throughout.
