WHAT IS ENSIWEB?
This is a collection of classroom lessons to help high school biology teachers more effectively
teach basic concepts in the areas of evolution and the nature of science. They were developed and tested during
nine years of summer institutes by biology teachers from across
SITE INTEGRITY is maintained through the oversight
by the three co-directors of ENSI:
Dr. Jean Beard (Biology Ed.)
Dr. Craig E. Nelson (Biology)
Dr. Martin Nickels (Anthropology)
and continuous feedback from the many ENSI and SENSI teachers,
professors and other users of this site. Check the People section for photos and bios of these
We are especially grateful to theNational Science Foundation for funding these institutes over the years and for extending
that funding to the development and maintenance of this web site
(NSF/TPE: 88-555-60 and 90-555-85 to Indiana University, and
91-552-59 to San Jose State University). We are also grateful
to Indiana University for allowing us the use of their web server
to make this material freely available to teachers.

WINDING DOWN - MAKING PLANS
It's that time of year again, when teachers are wrapping up the teaching year... and good teachers are looking ahead to next year. It's one of the most rewarding parts of teaching: Being able to make a fresh start each year. Time to reinforce what worked best, and replace or improve what didn't go so well. Or try something completely different.
All the new standards emphasize the importance for explicitly teaching the nature of science (NOS). Are you planning to do a better job on that next year? It's not too early to get started. Many teachers have already requested copies of the student text and the teaching guide, so they can prepare this Summer for teaching this unit in the Fall. Click here for more information, and to preview these materials.
Have a great school-year wrap-up.

Chromosome Comparison Lesson
(by Beth Kramer, ENSI 1992)
This lesson has been completely updated. Chromosome diagrams from Principle Investigator Yunis's 1980 paper have been replaced with diagrams from his 1982 paper. These are sharper, with more details, and similarities of human and great ape chromosome banding patterns are even more striking. Instructions, questions and answers (Key) have all been changed appropriately. Old html figures have been replaced with much sharper pdf figures. Family name of "hominoids" for humans and apes has been replaced with "hominids" to reflect current taxonomy (although orangutans are actually pongids). The Chromosome Comparison PowerPoint (and its script) have also been revised to show that change. Be sure to NOTE SPECIAL PRINTING DIRECTIONS near the top of the

If you do that lab, you can use lots of material from this issue
of Scientific American, showing what a dynamic and changing subject Paleoanthropology is.
Human evolution is still one of the best examples
of the science of evolution, with much evidence coming from fossil studies, DNA analyses, primate studies.
Talk about the power of multiple lines of evidence!
If you develop any new materials for teaching
human evolution, please share with us.
