Don't let the title of this Web site mislead you... this lesson plan contains a good, old-fashioned lab exercise, not an online simulation. Provided through the American Phytopathological Society, the exercise "demonstrates the biological phenomenon of the formation of a precipitate when an antigen reacts with an antibody," but uses inorganic salts in lieu of real (read expensive) viruses and antibodies. Detailed background information and lab procedures are provided, and the materials required are those commonly found in chemistry stockrooms. The Web site also includes study questions (answers provided) and a list of useful resources. A FAQ page may be forthcoming. A specific grade range is not mentioned, but this lesson plan could be a great addition to any life science course that covers the concepts of viruses, antigens, and antibodies.
