Kid's learn about the science of the molecules. Tiny chemistry and compounds of atoms and elements make up all matter.

These interactive materials will help you to understand how matter is made up and will help you expand your knowledge on matter. You will find an evaluation at the end.

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

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