Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

[Free Registration/Login may be required to access all resource tools.] Explains how to describe matter in the solid state, about the properties of liquid matter and gases, and what the relationship between energy and states of matter is.

In this module, you will learn why gases are not affected by intermolecular attractions! You will also learn about the properties of gases and the math associated with this special group of matter.

The differences between solids, liquids, and gases and the properties of each are presented in this lesson.
