This interactive activity developed for Teachers' Domain demonstrates how attractive forces between atoms create chemical bonds, resulting in the formation of molecules and compounds.

Young scholars observe reactions of liquids with different known powders in this lesson. Unknown powders are then identified using characteristic chemical changes.Site includes a procedure, teacher instructions, and video instruction.

Explains what intramolecular and intermolecular forces are and the different types for each. Includes lots of examples.

In this tutorial, students learn about ionic and covalent bonds and predict which elements will form which type of bond. Includes interactive exercises as well as videos.

Watch your solution change color as you mix chemicals with water. Then check molarity with the concentration meter. What are all the ways you can change the concentration of your solution? Switch solutes to compare different chemicals...

What determines the concentration of a solution? Learn about the relationships between moles, liters, and molarity by adjusting the amount of solute and solution volume. Change solutes to compare different chemical compounds in water.

This interactive periodic table developed for Teachers' Domain provides detailed information about the chemical properties of elements and illustrates the electron configurations that determine those characteristics.

Learn about the chemical reactions that take place when things burn in this interactive activity from the NOVA Web site.

In this interactive periodic table from the NOVA Web site, find out the role of various elements in making fireworks.

Through informational text with printable notes, interactive assignments, and video clips, students discover the structure and function of the human digestive system.

Throughout the day, your nervous system monitors and makes endless adjustments to your body's basic systems--all to keep you alive. This interactive feature illustrates the complexity of such a task.

Explains different kinds of energy, covering kinetic, potential, gravitational, mechanical, sound, thermal, chemical, electrical, and radiant energy. Also looks at storage, transfer, and dissipation of energy. Includes a short...

Find out your or your students' basic knowledge of concepts like matter, molecules and open and closed systems. Afterwards you can see how others answered the questions.

This digital textbook covers core chemistry concepts and includes interactive features, real-world examples, and videos.

Some molecules can be either left- or right-"handed." The left- and right-handed molecules have the same number and type of atoms, and their chemical structures look identical, but they are actually mirror images of each other. Many...

This video segment from Interactive NOVA: "Earth" looks at photosynthesis, the chemical process plants use to make their own food.

A brief description of cycloalkanes. Properties, chemical make-up, and structure provided. Brief introduction to nomenclature of cycloalkanes and generic formula. Interactive piece requires x-pdb plug-in.
