Discuss Archimedes' Principle and fluid forces with your young scientists as they describe the relationship between mass, volume, and density during a series of engaging activities. They use the Participle Theory of Matter to explore the...

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....

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...

Given descriptions, scenarios, or illustrations, students will distinguish between the compressibility, structure, shape, and volume of solids, liquids, and gases.

Students learn about solids, liquids, and gases in this interactive slide show. Animated cartoon characters explain concepts having to do with properties of matter. A self-checking quiz follows the lesson.

A collection of cartoon animations that teach students what they need to understand about solids, liquids, and gases.

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

[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.

Using simulations observe what solids, liquids, and gases look like at the atomic scale. After observing the different states of matter at their atomic level, students will be able to conclude about the forces and attractions that exist...

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.

[Free Registration/Login may be required to access all resource tools.] In this learning module, students examine differences in physical and chemical properties of solids, liquids, and gases.

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...

In the States of Matter module, students further explore the concept that anything on earth that has mass and takes up space is matter. This exercise introduces students to solids, liquids and gases, the three most common states of...

Students investigate the structure and parts of the atom, and learn about atomic mass and atomic number. They also explore the differences among solids, liquids, gases, and plasma.

[Free Registration/Login may be required to access all resource tools.] Freshly baked bread and cherry pie are two delicious parts of any meal. What happens to the ingredients that go into the bread and the pie as they are heated in the...

[Free Registration/Login may be required to access all resource tools.] In this online tutorial, students will begin to understand a substance according to its physical properties. Learn to distinguish between extensive and intensive...

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...

[Free Registration/Login may be required to access all resource tools.] Definition of state of matter and the three common states of matter and their differences.

Students will look at what happens to different types of matter when they have a change of state.

Learn about topics related to the material world. Each topic includes facts, a glossary, an interactive quiz, printable worksheets, an image bank, and web links.
