Dare your class to drive dissolved carbon dioxide out of carbonated liquid at different temperatures to discover if there is a difference in rate. To make this experiment more sound, have explorers use equally measured amounts of soda...

In one of the more memorable Spangler episodes, Spangler has a large terrarium filled with sulfur-hexafluoride gas, which is six times heavier than the air we breathe! It has some amazing properties, one of which it doesn't allow...

Middle schoolers explore heat energy and how it is used to change the phase of matter, and discover that temperature does not increase or decrease until the phase change is complete. This extremely well-written plan is packed with great...

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

Pair earth scientists up to use an amazing online arctic portal mapping tool and Google Earth to analyze permafrost changes. They compare changes to data on atmospheric concentrations of methane to see if there is a correlation. Then...

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...

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.

What a great resource! This presentation is informative as is, but there are links provided to some great resources that can help learners explore the states of matter in greater depth. For example, there is a link to a website that...

In this episode of "Steve Spangler Science" videos, the gas produced by the sublimation of carbon dioxide dry ice creates a nice, fluffy cushion in a bowl of water. Since it is less dense than a soap bubble and cool enough to keep it...

A teenaged Jack Spangler demonstrates how reducing air pressure in a bottle can pull a boiled egg inside. Then dad does a similar demonstration using liquid nitrogen to reduce the air pressure. Even though the result is the same, the...

Create a cauldron of bubbling fun with this Halloween-themed demonstration idea. Using dry ice, Steve Spangler creates a crystal ball. If you compare the sublimation of dry ice to the melting of water ice, it is a wonderful way to...

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...

Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...

Third graders study the three states of matter and identify the physical changes that take place between them. There is an initial teacher-led demonstration followed by a meaningful whole-class inquiry. These two activities should lead...

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...

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...

A teacher with talent has created a fun set of review questions on the changing states of matter. Cycle through 15 questions, multiple choice answers, and a monetary reward for guessing correctly. Use this game show PowerPoint to help...

The question is posed, is it permeable or impermeable, it's up to your critical thinkers to determine the answer. This presentation provides several scientific concepts related to permeability and the properties of matter alongside...

Second graders identify the three states of matter by examining fishbowls with various contents. They discuss their observations and the characteristics of matter in each state. Pupils read the story The Rainbow Fish and look for...

Students examine containers and their capacity. They fill a one-cup measuring cup with water and pour cups of water into other containers. Through observation, students discover how many cups make a pint, and how many teaspoons make a...
