States of Matter

Certain things just do not mix, including liquids of varying densities. Learners collect data to determine the densities of several liquids. They then use the density information to predict the type of liquid.

Students explore the cycles of an ecosystem.  In this environmental science lesson, students work in groups to research the nitrogen cycle, the water cycle, or the oxygen-carbon dioxide cycle. Students prepare a PowerPoint or other...

What's the matter? Gas, solid, liquid, or plasma. The presentation covers how to describe and identify matter, changes in matter, types of matter, measuring matter, particles of matter, Democritus, and John Dalton's Atomic Theory.

Do solids, liquids, and gases even matter? The presentation focuses on changes in matter, including phases, Boyle's Law, Charles' Law, and physical changes. 

As the title implies, this PowerPoint defines and illustrates the basic terms involved with describing matter. Phases of matter, atomic structure, and the different categories of compounds are included. Slides are simple and uncluttered....

"Self-guided Computer Activity" simply means that young chemists read through the slides and take notes about atoms along the way. There is an abundance of text on each slide, making this a comprehensive introduction to atomic structure....

In this lesson, students compare similarities in the embryos of different organisms to look for features that would indicate common ancestry. They will then investigate how understanding this aspect of evolution has real-world...

A dynamic, three-part feature explores what caused mass extinction of the dinosaurs at the end of the Cretaceous period. Computer animations, interviews, and on-site footage from around the world divulge evidence that it was the K-T...

Introduce materials science with a class demonstration. After showing a PowerPoint presentation on materials and their properties, instructors provide a ceramic tile, a Popsicle stick, a paper clip, and a plastic bag as examples of...

The sun is responsible for almost 99 percent of the solar system's mass. As an essential part of our lives, the sun has many important features. A PowerPoint lesson presents information about features such as sunspots, the magnetic...
