Mixtures
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.
Science Background
Mixtures and Solutions: Newton, Ask a Scientist (website) - Explains the difference between mixtures and solutions.

Mixtures: Virtual Education (website) - Short page with straightforward explanations of mixtures, solutions, suspensions and colloids.
Signature Lesson
Kinds of Mixtures: K8 Science (PDF) - Working in teams, students observe, compare and contrast different kinds of homogeneous and heterogeneous mixtures.

Assessment Ideas
Have students create different mixtures and explain the properties of each. Alternately, or as an additional assessment, have students research different types of mixtures and how they are used in everyday life.
