"Matter is everything." So begins this comprehensive website on the physical and chemical properties of matter in its four main states: solids, liquids, gases, and plasmas. The text is large and easy-to-read. Students will enjoy the...

Observe the differences between solids, liquids and gases.

Kid's learn about the science of states of matter. Solids, liquids, gases, and even plasma.

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the...

An interactive simulation will heat, cool and compress atoms and molecules. Watch as they change between solid, liquid and gas phases. Recognize that different substances have different properties which will affect the temperatures for...

After watching this simulation, students will be able to describe characteristics of the three states of matter. They will watch as atoms and molecules change between solid, liquid and gas phases.

[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.

During this lesson, students will practice observing, question writing, and answer generating based on taking part in experiments. Students will work with different substances to observe changes in liquids, solids, and gases.

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...

Concept animation compares molecular movement of solids, liquids, and gases.

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.] In this learning module, students examine differences in physical and chemical properties of solids, liquids, and gases.

[Free Registration/Login Required] This flipchart gives a flowchart depicting the states of matter-solid, liquid and gas. Students are asked to complete a chart placing various items into these categories.

States of Matter is an educational activity for kids to learn about the different properties of matter. The lesson will introduce solids, liquids, and gases. Students will then be assessed through a sorting activity where they will...

In this activity about matter, students investigate the three states of matter by participating in a small group lab. Students will observe, question, and investigate the properties of solids, liquids, and gases.

A lab activity where students determine the state of matter of the "oobleck". Students will create a lab procedure to investigate the state of matter. Site includes handouts for the activity.

This interactive assessment features 7 matching, 7 multiple-choice, and 6 true/false questions over 20 terms related to Solids, Liquids, and Gases (the three states of matter).

This set of interactive flashcards focuses on 20 terms related to Solids, Liquids, and Gases (the three states of matter).

This lesson focuses on Matter including the three states of matter, the energy that it takes to change the state of matter, and experiments for children to conduct. Students can choose to have any paragraph read to them.

Provides interesting information about the three basic states of matter: solid, liquid, and gas.

Learn about matter, its three states, changes of state, how matter behaves, and physical and chemical changes in matter.

[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...

This lesson focuses on solids, liquids, and gases. It has several review activities and an exciting lab experiment involving ice cream to complete the lesson.

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...
