Changes of States of Matter

Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...

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.

How does heat move from one item to another, even when the items are in different states of matter? Pupils experiment with adding washers to hot water and adding hot washers to room temperature water to observe the heat transfer. 

Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

You don't have to be a scientist or even out of high school to contribute to scientific research. In the 12th lesson in the series of 21, scholars use this opportunity to add to the growing body of scientific knowledge and consider the...

Characteristics of each state of matter are listed, the formulas for heating water are detailed, and values for boiling and heat of vaporization are presented. This simple slide show provides direct instruction as well as practice...

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,...

Poor Sam! His graham crackers have undergone a physical change, so he can't make his s'mores! Mia explains that their molecules haven't changed, therefore they are still graham crackers. The two teens then discuss clues that would...

While clouds may not make for the most enjoyable weather, they play an important role when it comes to regulating the temperature of the earth. Watch this video and learn how these giant masses of water droplets actually help to...

Build a strong foundation for your teaching of stability and change! The video addresses the Next Generation Science Standards Cross-Cutting Concept through insightful examples. The narrator includes ideas for introducing the standard in...
