These are a list of sites that are extremely interactive making extensive use of java applets. For individual applets see --More Applets (to the left).

These applets target a K-12 population but are also ideal for higher level viewers and excellent for Internet Surfers looking to expand their knowledge base in science. You will need Flash and Java installed on your computer.

Physics 2000- Physics 2000, is an interactive journey through modern physics! Have fun learning visually and conceptually about 20th Century science and high-tech devices.

MathMol Hypermedia Textbook (Version2) This second edition keeps the content about molecules and their connection to mathematics, but now includes java applets, and flash animations so viewer need not download any additional software.

Molecular Expressions - go where no microscope has gone before -- - one of the Web's largest collections of color photographs taken through an optical microscope (commonly referred to as "photo-micro-graphs)

Human Anatomy Online Skeletal, Muscular, Digestive, Lymphatic, Endocrine, Nervous, Cardiovascular, Reproductive and Urinary Systems... Includes extensive images and descriptions.

Cell Biology Animations -- Amino Acids and Proteins, Cell Structure, Diffusion, DNA, Glycolysis, Krebs Cylce, Meiosis, Mitosis, pH, Photosynthesis and Water.

Visible Human Project (NLM) -anatomically detailed, three-dimensional representations of the normal male and female human bodies. Acquisition of transverse CT, MR and cryosection images of representative male and female cadavers has been completed. Online browsers available.

Explain it with Molecules --Why does ice float?-- How does soap work? -- Why is diamond so hard?-- Why do carcinogens like nicotine cause cancer? -- Why is a salt crystal cubic in shape? -- This is an interactive activity using the JMol applet which allows students to interact with molecules. No plug-in is needed.

Concord Consortium (BioLogica) BioLogica™ is a a hypermodel for teaching high school genetics. The software runs on both Windows and Macintosh computers. Several excellent activities (including 2 sample programs and a 3-D java applet of a cell do not require downloads

Visible Human Server- Contains 2-D and 3-D views and animations of the human anatomy. Requires registration for some applications.

Virtual Molecular Dynamics Laboratory - enables the student to visualize atomic motion, manipulate atomic interactions, and quantitatively investigate the resulting macroscopic properties of biological, chemical, and physical systems.

Satellite Tracking (NASA)- -This is a great way to locate the Space Station, Hubble Space Telescope, Chandra X-Ray Observatory or any of your favorite satellites. They even add the Space Shuttle (during missions). This tracker is also used by their remote scientists to keep up with their missions.
