This lesson introduces students to the important concept of density. The focus is on the more easily understood densities of solids, but students can also explore the densities of liquids and gases. Students devise methods to determine...

This lesson focuses on the states of matter: solids, liquids, and gases. It also discusses the Kinetic Theory of Matter, Thermodynamics, Triple point, Phase Change Graphs and the Heating Curve of Water. It provideds adrawing of a heating...

This article tells what specific gravity and how to compute the specific gravity for solids, liquids, and gases.

Did you know the ancient Greeks first identified the three states of matter? Read about how the molecules differ in solids, liquids, gases, and plasma. View photographs and watch how the molecules move in each state. If you're really...

Students will witness a fascinating chemical reaction and learn how to identify when a reaction has occurred by combining simple ingredients.

Students observe a molecular dance of bursting colors through exploring states of matter and learning that materials can be characterize by how they respond to water.

Learners characterize materials by their state of matter and then combined materials to create a piece of colorful, tie dye-esque paper.

Learn about the three phases of matter, and how the addition and removal of thermal energy (also known as heat) affects them.

A very descriptive site that allows students to understand the different states of matter at the atomic level. Also discusses the process of phase changes and displays phase change graphs. Thermochemistry is also touched upon for high...
