Computers can add a whole new dimension to biology laboratory instruction. An overview of how microcomputers are used in laboratory exercises at the Atlantic Veterinary College is presented. Since finding appropriate software can be difficult, a description of the software used at the College and a discussion on how to find other software appropriate for such instruction is included. Such software can be innovative and comes in a variety of teaching formats, including tutorials and simulations of experiments. Color graphics, sound, and animation may be incorporated into the software to enhance its effectiveness.
Dermatoglyphics is the study of epidermal ridges on the hands and feet.
Ridge patterns and counts develop prenatally, are inherited, and show quantitative variation. This exercise introduces the preparation and interpretation of finger and palm prints for quantitative analysis. The techniques are simple, inexpensive, and can be adapted as an exercise on genetics for beginning or advanced students. Palm prints from individuals with Down Syndrome serve as a population sample to statistically test for differences with the class population and also create an opportunity to discuss the cause and effects of Down Syndrome. Several tissue culture procedures, ranging from simple to more complex, are examined.
