These links are privided as starting points for searching for information. They are not comprehensive, but should serve as a guide for getting into the vast amount of biology and related information that is available on the Internet. While some of the links are to sites targeted at professional biologists, we have tried to restrict the list to links that also have some useful information for students of high school biology.

General Biology

  • Carolina Biological, which includes access to Carolina Tips, some of which are also available at the Access Excellence site.

  • Tree of Life. Information about Phylogeny and Biodiversity.

The Tools of Biology

  • Microscopes and Microscopy. A central site for microscopy on the Internet. "Microscopes and Microscopy" recently achieved a major milestone: 100 Web sites are now in its index. (A Yahoo search in the same subject produces only 16.) Maintained by Chris Jeffries, these comprehensive and well-organized pages have listings of everything from ftp sites to mailing lists to conferences. There is also a section called "In-Focus" where you can read essays on tripod polishing, the history of microscopy, and other related topics.

  • Scanning Electron Microscope

Virtual laboratory Exercises

  • An online frog dissection tutorial brought to you by the University of Virginia's Curry School of Education. Intrepid visitors are invited to take scalpel (a.k.a. mouse) in hand for some major surgery. Just don't expect a quick slice and dice; the heavy use of graphics and MPEGs makes for slow going unless you have an incredible amount of RAM. Topics covered by the dissection include muscle incision, skin incision, and internal organs.

  • Virtual frog dissection kit. Interactive dissection of a frog which includes a tutorial and an overview.

  • Virtual FlyLab. Budding research geneticists and mad scientists will be equally drawn to this site, which allows users to virtually "breed" fruit flies in search of the secrets of genetic inheritance. The FlyLab is well documented and illustrated, making it a pleasure to use for those who aren't squeamish about drawings of forked fruit fly bristles. This "virtual application" was designed by the Electronic Desktop Project at California State University, Los Angeles.

  • The Virtual Embryo.

  • The Lung Tour. LungTour is a set of images of the lung made with the Scanning Electron Microscope and organized in hyperimage format to allow you to travel through and see in more and more detail the structure of the lung.

  • Cow Eye Dissection. The Cow's Eye Dissection is one of the most popular demonstrations at the Exploratorium. For many years it has helped people satisfy their curiosity about what is inside an eye. The material presented here is meant not to replace the act of dissecting a cow's eye, but rather to enhance the experience.
