ChemCenter, available from the American Chemical Society, provides chemistry news, reference sources and other public services.

Here you can find all kinds of helpful information about chemistry. Learn about reactions, elements, atoms, matter, or biochemistry. Downloads and activities are also included.

Matter is all around us, so it's a good idea to know what it is, and why it matters. Learn about matter, its categories, and its subcategories with this interactive lesson.

[Free Registration/Login Required] Explore the composition of air and learn about the different atoms and molecules that we breathe every day.

[Free Registration/Login Required] This flipchart is a guided activity to help students compare different types of matter: atoms and molecules, elements and compounds, mixtures and solutions. It corresponds to Virginia science SOL 5.4.

Find out the basic characteristics and main properties of all matter.

Kids learn about the element mercury and its chemistry including atomic weight, atom, uses, sources, name, and discovery. Plus properties and characteristics of mercury.

A basic explanation of spin and how it relates to electrons and quantum numbers.

Help the Phantom choose a material and observe the changes at different temperatures in the molecule chamber. What happens to the elements or molecules as the temperature changes?

These notes from a Chemistry 101 class at Indiana University Northwest provide a simple description of atomic symbols and two examples of how to use those symbols in isotope notation.

Interactive concept animation shows the atomic number, weight, and structure of the first eleven elements of the Periodic Table of Elements.

A detailed slideshow for Grade 8 students that looks at the history of our understanding of atoms. Looks at the ideas presented by Democritus, John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr, and the modern-day wave model. A...
