Comparing Mixtures and Solutions
TEKS Objective
The student is expected to compare and contrast a variety of mixtures and solutions such as rocks in sand, sand in water, or sugar in water.
Essential Understanding
The student knows that matter has physical properties and those properties determine how matter is classified, changed and used.

Assessment Ideas
Give students a variety of sample substances (e.g., sand and sugar mixed together, carbonated beverage, piece of concrete, salt). Ask them to identify the samples that represent a mixture and to explain their answers. [Pure salt is not a mixture; all the other examples are.] Then, have students identify the mixtures that are solutions. [The carbonated beverage, “soda,” is an example of a solution.]
