Solids
TEKS Objective
The student is expected to describe and classify samples of matter as solids, liquids, and gases and demonstrate that solids have a definite shape and that liquids and gases take the shape of their container.
Essential Understanding
The student knows that matter has measurable physical properties and those properties determine how matter is classified, changed, and used.
