What Is the Matter?

Solid, liquid, and gas: they all matter. Scholars create an animation of the various states of matter, experiment with the temperature of water as it changes states, and observe carbon dioxide as it changes states. The lesson also...

In this phases of matter worksheet, learners complete 13 fill in the blank spaces with science words from the given word bank. The blanks are placed within an informational paragraph about solids, liquids, and gases. 

Young scientists get to the heart of the matter as they complete this instructional activity on the properties of solids, liquids, and gases.

Not many lessons on states of matter can hold a candle to this one! Junior chemists gauge the density of paraffin in both liquid and solid phases. They fill 60 mL syringes with different materials to experiment with compressibility and...

Delve into the differences among solids, liquids, and gases with this PowerPoint. It is both applicable and attractive. Large, colorful diagrams display the molecular arrangement of each state of matter and their properties are arranged...

Display the arrangement of molecules in solids, liquids, and gases. Demonstrate how the addition of heat energy results in greater molecular motion and therefore a change of phase. Give examples of heat conductors and insulators, and...

There are four states of matter: solid, liquid, gas, and plasma. As this clip describes, the key to changing the states of matter is the addition or subtraction of energy. Learn about molecules, heat, plasma, and the science behind...

Your physical science class learns that there are three states of matter, and that adding or removing heat can cause it to change from one state to another. By the animations, printed information, and discussion between RJ and Zoe, they...

Watch a three-minute video about states of matter, sing karaoke about matter, learn vocabulary, and take a quiz.

Most of us are familiar with the three states of matter—solid, liquid, and gas. But what about plasma? Yet 99.9% of the universe is made of plasma. Get the scoop on this gooey goo.
