Classifying Matter: A Concept Map

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...

Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

How did ancient scientists classify elements? Answer this question and others as young chemists create a device to test the properties of various elements. They classify elements as metals or nonmetals, learn to differentiate between...

A collection of concept maps has some terms filled in and others left blank for young scientists to fill in. This library can provide you with many pop quizzes for all of your middle to high school science curriculum. 

Tenth graders review the Energy, Matter, and Organization unit. They have one week to complete an essay. Students must submit a concept map or drawing. The activity is introduces by reading a short story line which presents a simple...

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

Compound class members' knowledge of elements and compounds with this delightful video clip! As the animated characters work on baking a birthday cake, they reveal that elements are simple substances that can be combined to form...

In 1924, Bose and Einstein predicted a fifth state of matter. The prediction proved to be true in 1995 and is referred to as the Bose-Einstein condensation. This video discusses the concept of matter, all five states of matter, and what...

Investigate boiling point, melting point, and the molecular makeup of matter in a little over a minute! Scientists explore the physical properties of matter, how different materials have a specific set of physical properties, and the...

Why did carbon marry hydrogen? They bonded well from the minute they met. Here is a video that focuses on the essential chemicals for life: water, carbon, nitrogen, and phosphorus. It relates each of these to macromolecules and the way...
