This web page contains a large set of three-dimensional molecular models, which can be rotated and enlarged by the user. Included are models of carbon in three forms, 8 metals, 6 non-metals, hydrocarbons, tetrahedrals, acids, alcohols, esters, ethers, proteins, organic structures, saccharides, and more. By using the mouse to rotate images, students can readily see the molecular geometry in the positions of the constituent atoms. Right click to zoom up to 800%, view element symbols and atomic numbers, measure the structure, or highlight the bonds in a customized color choice.
Editor's Note: Be sure not to miss the additional materials in this large collection. Author Mark Bishop also created two textbooks in introductory chemistry (available in free digital format), Power Point presentations for teachers, tutorials, student guides, and more.

4. The Physical Setting
4D. The Structure of Matter
6-8: 4D/M1a. All matter is made up of atoms, which are far too small to see directly through a microscope.
6-8: 4D/M1b. The atoms of any element are like other atoms of the same element, but are different from the atoms of other elements.
6-8: 4D/M1cd. Atoms may link together in well-defined molecules, or may be packed together in crystal patterns. Different arrangements of atoms into groups compose all substances and determine the characteristic properties of substances.
9-12: 4D/H7b. An enormous variety of biological, chemical, and physical phenomena can be explained by changes in the arrangement and motion of atoms and molecules.
9-12: 4D/H8. The configuration of atoms in a molecule determines the molecule's properties. Shapes are particularly important in how large molecules interact with others.
11. Common Themes
6-8: 11B/M1. Models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly. They are also used for processes that are too vast, too complex, or too dangerous to study.
6-8: 11D/M3. Natural phenomena often involve sizes, durations, and speeds that are extremely small or extremely large. These phenomena may be difficult to appreciate because they involve magnitudes far outside human experience.
12. Habits of Mind
12C. Manipulation and Observation
6-8: 12C/M3. Make accurate measurements of length, volume, weight, elapsed time, rates, and temperature by using appropriate devices.
