This site helps students construct a model of the arrangement of water molecules when present as solid, liquid or gas. Includes background information, lesson plans, links to standards and assessment ideas.

Join a group of middle-school students on a visit to a laboratory at the Massachusetts Institute of Technology, where they experiment with "mystery mud" and learn about the relationships between magnetism, particle motion, and changes in...

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...

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...

By the end of this section, you will be able to state the common phases of matter; explain the physical characteristics of solids, liquids, and gases; and describe the arrangement of atoms in solids, liquids, and gases.

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...

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

An eBook containing information regarding states of matter as it applies to celestial bodies and a universe.

As part of a larger site called "Getting started in Chemistry," this site examines various topics related to the densities of substances and materials. Included in the study are properties of solids, liquids and gases, and how density is...

As learners begin their study of states of matter, this hands-on activity demonstrates how the interaction of a solid and a liquid can reverse the initial state of each material.This lesson plan was created as a result of the Girls...

In this activity, students construct models of molecules using marshmallows and gum drops.

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