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

Engaging hands on science lessons for grades 2-6 on the three states of matter.

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.

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

An experiment in viscosity using cornstarch and water. Includes a detailed explanation of viscosity, of Newtonian and non-Newtonian fluids, and examples of different fluids that fit into each category.

Background information: This activity is an extension of the children's exposure to states of matter in the Scott Foresman science series for Grade 2. This lesson has a Literacy component. Using the book by Dr. Seuss, "Bartholomew and...

Allow your students to explore states of matter as they learn what causes frost to form on the outside of a cold container. Students will observe how liquid water can change to ice or water vapor in this lab. Lesson includes background...

This lesson teaches students about how sound vibrations are transmitted through solids, liquids, and gases, and about how materials may absorb sound.

Students discover intermolecular attractions between neighboring molecules. These intermolecular attractions, or IMA, affect the behavior of liquids, solids, and solutions.

Learn about kitchen chemistry alongside Ruff Ruffman. Students can use the videos, games, and activities from The Ruff Ruffman Show to discover how by investigating solids and liquids and exploring heating and cooling, science can help...

Printable classroom-ready worksheets for a series of simple-to-implement experiments about the states of matter.

A released question from the Trends in International Mathematics and Science Study (TIMSS) assessment about change of states of matter. Also included is a scoring guide for the released question.

[Free Registration/Login may be required to access all resource tools.] Explains what happens to matter when it freezes and the definition of freezing point.

A description of a lesson where students navigate through twelve stations on solids and liquids and record their observations in a booklet. The station topics are listed, but the recording booklet materials were purchased from...

Colorful site provides a brief summary as well as engaging pictures of the three states of matter: solid, liquid and gas.

In this Physical Science experiment, learners investigate how sound travels through different mediums, including solids, liquids, and gases. This particular experiment deals with solids by using a wire hanger and two pieces of cotton...

A video and a short quiz on the periodic table of elements and how it is organized.

In this lesson, students use their science knowledge and apply it using physical activity! Learning about the stages of matter, solid, liquid and gas, students perform an exercise for each as the teacher calls out an object such as soup...

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.

This site contains an interactive activity in which students can learn about the three states of matter. There is also a factsheet that lists numerous properties of liquids, solids, and gases. The factsheet also uses water as an example...

Percy Julian and Josef Pikl used the fact that melting point-the temperature at which a substance changes from a solid to a liquid-is a characteristic property of a substance to prove that the British chemist Robert Robinson could not...

A series of interactive applets use scientific models to teach some basic concepts of matter, including states of matter and physical and chemical changes.

In this lesson, students will move and generate choreography to understand different states of matter.

A great resource to discover fun new activities to use in your classroom. Activities are age-appropriate, and span several science topics.
