The Three States of Matter: Energy Matters

Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.

From gas to liquid condensation to solid frost, water undergoes phase changes before students' eyes! Using ice, salt, water, and a metal can, they set up an investigation that can be used in a physical science setting, or as part of a...

This PowerPoint is a gem! Seventy-eight slides present an entire introduction to matter in bullet-point fashion. Viewers learn about everything from mass and inertia to phase changes and gas laws! The only glitch is that the links to...

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...

The three states of matter are the focus of this chemistry video. Sal uses the example of a water molecule and explains in great detail the forces present that allow the molecule to change between a liquid, a solid, and a gas. Of course,...

Sal continues his explanation of the states of matter by focusing on hydrogen bonds. This time, he uses plasma as the substance being studied, and explains how the hydrogen bonds change as the substance goes from solid to liquid to gas.

A problem from a chemistry textbook is posed on the screen. In this problem, ethanol is used to illustrate the amount of energy, in joules, required to change a substance from a liquid to a gas. The boiling point of ethanol is given, and...

Twenty-four questions about matter, the states of matter and the properties of matter make up this interactive online learning exercise. Your class will determine the volume of water, the shape of water and the shapes of matter.

Middle schoolers explore and identify phases of matter and compare the particle motion in solids, liquids, and gasses.

Explore the states of matter without the mess or expensive equipment in a compact, informative activity. Scientists watch as the narrator explains the three states of matter using a glass of ice and soda in an animated video that...
