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
the nation.
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
people.

THANK YOU
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. |
| YOUR CHANCE
TO RATE US We are now linked to
"BioScience

MORE SUMMER READING
Natural Selection Myths
Rich Transitional Fossil Series
"Missing Link" Myth
Evolutionary Trees & Cladograms
Read my brief reviews of several excellent articles that are
freely downloadable from the Evolution Education Outreach
Online - a special edition with articles on the current state
of understanding about Transitional Fossils, Natural Selection
Misconceptions, and Evolutionary Trees. These articles are
written by professionals in their respective specialty fields,
but sufficiently non-technical that high school biology teachers
should have little difficulty reading them, and using selected
material in their classes. You will discover the awesome numbers
of very rich transitional fossil series that we have,
underscoring the compelling evidence for evolution that we have.
Another important article in this volume addresses the many
misconceptions about natural selection. Studies show
that even many college biology majors and biology teachers unknowingly
carry some of those misconceptions - and are passing them on
to their students. The author offers tips into how teachers
might be able to help their students discover where their understandings
miss the boat, and how to repair them. This article is a must
read.
Likewise for articles about the "missing link"
myth, and on evolutionary trees & cladograms.

DARWIN
QUEST: Journey to Darwin-Land
With vacation time rapidly approaching, and with so many programs
honoring Charles Darwin this year, the 200th anniversary
of his birth, and the 150th anniversary of his Origin of Species,
give some serious thought to visiting a place that honors
him. It could re-energize you and give you some insights
and memories to share with your kids. The exchange rate with
England is better than it's been for some time (the pound is
worth only about 1.5 times the dollar, down from about twice
the value last year). And airlines are offering very nice economical
packages, too. Click
here for specific objectives where to explore, and
what to look for, especially in England. If you plan to go, let
me know: I'm looking for feedback on a number of questions.

FOUR-WINGED DINOSAURS
A New NOVA program on the
origin of birds and bird flight
The Tentative Nature of Science, and
How Phylogenetic Trees are Made
Excellent program, showing how new evidence and analytical
techniques can bring about changes in the interpretation of data.
Two major views of the origin of bird flight are presented, along
with recent studies and fossils that shed light on the issue.
This online site provides viewing of all 6 parts ("chapters")
of the program, so that one or more can be shown to your students,
with discussion in between. If you develop
a worksheet with questions for students to answer (in class or
at home) during viewing, please share.
How the different views (and new evidence) affects the construction
of phylogenetic trees would be an excellent sequence to show
during your unit on classification or evolution. See Chapters
2 and 6 for these clips.

YOUR INNER FISH
by Neil Shubin
Great Summer Read
Co-discoverer of the "fish with wrists" fossil Tiktaalik
in Canada, 2006, Shubin traces many of our human traits and problems
back to their origins, many of them inside our cells and found
in the bacteria of today. This paleontologist also teaches anatomy,
and recounts how knowledge of the features of existing fossils
from around the time that vertebrates moved onto land led to
his predictions for where he might find better evidence of that
transition. Shubin shares many examples of how both science
and evolution work.
Very readable, certainly for high school students,
and even middle school students. Teachers will find many observations
and stories to share.

PATTERNS IN TIME
New lesson, different
than most that may look similar.
This one helps students to gradually build a realistic sense
of deep, geological time from familiar linear analogs. Students
also discover when the earliest fossils of each major vertebrate
class first appeared, over several 100s of millions of years,
and gain a sense of their gradual changes over time.
Especially suitable for middle school Life Science.
NOT CLASSROOM TESTED YET.

EXPELLED ---
EXPOSED!
As you may be aware, the Ben-Stein-narrated feature
Expelled: No Intelligence Allowed
premiers this weekend (April 18, 2008).
Some of you may get questions about the film from students.
But not to worry... NCSE brings you... Expelled Exposed.
Welcome to Expelled Exposed - a detailed look at the
Ben Stein movie Expelled: No Intelligence Allowed. We'll
show you why this movie is not a documentary at all, but
anti-science propaganda aimed at creating the appearance of controversy
where there is none.
To learn why the claims made in Expelled are false,
find out The Truth behind the Fiction. For information on the
producers and their actions, go Behind the Scenes. To learn more

SCIENCE,
EVOLUTION, AND
CREATIONISM
Review by Larry Flammer
New Book by the National Academy of Sciences
and the Institute of Medicine (2008):
This is the third and much improved edition of the NAS's Science
& Creationism. It is far more comprehensive, yet brief
enough to use as a classroom supplement. It clearly presents
and explains the essential features of the nature of science,
evolution, creationism in all its variations, and their critical
interactions. Highlights include a discussion of evolution as
fact and theory, and an example of an industrial application
of natural selection. There are excellent explanations of how
molecular biology repeatedly confirms evolution.

TEACH
EVOLUTION MORE EFFECTIVELY
If you are looking for practical ideas that will help
you to teach evolution,
take a look at these two articles.
They were published last year and offer specific suggestions
for
teaching evolution more effectively.
The first one was by ENSI Co-Directors, Craig E. Nelson, with his article published
in the special edition of the McGill Journal of Education,
Spring 2007. See http://www.indiana.edu/~ensiweb/teach.evo.nelson.html
The other, by Jennifer
Robbins and Pamela Roy, was published in The American
Biology Teacher for October 2007. How would you like to see
your students increase their accurate explanations
of evolution from 6% before the unit, to 92%
afterwards? Likewise, wouldn't it feel good if the number of
your students accepting evolution
as a viable explanation of diversity went from 59% before your
course to 92% afterwards? These
are the kinds of results obtained from a closely monitored approach
to teaching evolution. See more details at http://www.indiana.edu/~ensiweb/effective

The Evolution Solution:
Teaching Evolution
Without Conflict
Observing life seems to contradict traditional ideas and raises
tantalizing questions. Show how evolution answers those questions
and provides unity throughout your course.
Abstract: A strategy for teaching high school biology
that opens with an intensive nature-of-science unit followed
by question-raising topics, leading directly to evolution as
a solution and a unifying theme. This special sequence-using
specially designed student-centered lessons-is compelling and
non-threatening for students.
Article by ENSI webmaster
Larry Flammer in the March issue of the NABT Journal, new online
version. Ideal for new teachers still searching for an effective
approach to teaching interactive biology with strong nature-of-science
and evolution themes throughout. Classroom tested over many years.
Direct links to many ENSI lessons and resources in context.

NEW
TAXONOMY for APES AND HUMANS
Molecular and genetic studies have made it increasingly clear
that apes are biologically much closer to humans than their traditional
taxonomy would indicate (if classified by the same criteria used
for other species). As a result, a taxonomy that reflects that
relationship much more accurately has been adopted. The main
changes: the family Hominidae ("hominids") now includes
the African apes along with humans, and all humans (including
all their extinct bipedal predecessors and cousins) are now placed
in the subfamily Homininae ("hominins"). Every
effort is being made to reflect those changes in all the material
(lessons and articles) on this site. This includes a number of
modifications to our Chronology
Lab, where the hominin fossil record is plotted on a
chronological time scale, clearly showing the bush-like nature
of our "family tree." We have also made major changes
to our Primate
Classification "boxes-in-boxes" lesson. If

CRITICAL
THINKING
by Howard Gabennesch
in the Skeptical Inquirer magazine, March/April 2006,
pp. 36-41
Available on newsstands now
What IS it? What is it NOT? What are the benefits? Why is it
important?
Dr. Gabennesch presents a working definition: " the use
of rational skills, skeptical worldviews,
and values to get as close as possible to the truth."
He points out that, according to the NSF, "science education
is not producing high levels of scientific literacy in the population.[and]
there appears to be only a weak relationship between science
knowledge and disbelief in various forms of nonsense."

This is a most informative and useful issue with excellent
teaching ideas. Check your newsstands, get a copy, and read
it! Below are some abstracts for the main articles, but you need
to read the articles to see how you could apply their contents
to your teaching.
CAPSULES (Click here
for more details on 3-page PDF):
Mark Perakh shows how Behe's "irreducible complexity"
argument (key support for "intelligent design") is
not only erroneous, but also becomes an argument against
"intelligent design."
David Morrison suggests that we should avoid using the
T word in "theory of evolution. He also points out other
ways to "level the playing field," so that creationist
are not put on the defensive, show why it's so important for
everyone to understand evolution, and might be more willing to
at least hear what you have to say about evolution (?)
Jason Rosenhouse uses the Cambrian "explosion"
to expose an example of how creationists purposely quote scientists
out of context to convey negative ideas about evolution.
Sean B. Carroll explains how we can use the new field
of Evo Devo to ignite enthusiasm with visible evidence of how
evolution happens. Lots of good ideas for making evolution the
central theme of your course.

This article makes a strong case for using lessons that provide
experience with a critical yet seldom addressed process of science:
Historical Science, in contrast to the "The"
Scientific Method, the process used in experimental science,
and usually the only process of science presented in science
classes. Historical Science is equally valid, and is the basis
for many studies in many fields of science, including paleontology,
geology, astronomy, evolution, and forensic science.

Should be "Required Reading"
for all Biology Teachers:
Why so many people fail to recognize the reality
of evolution, and
Why the peppered moth remains a strong "icon" of
evolution.

"Testing Darwin":
Scientists at Michigan State
"Prove" Evolution Works, by Carl Zimmer
Discover Magazine, February 2005
A fascinating article in Zimmer's usual very readable style.
Digital organisms that develop through random mutations and
natural selection are helping scientists
answer some of the biggest qestions of evolution.
They also pose a mystery of their own:
Have scientists created a simulation so realistic that it
qualifies as a new form of life?
And another interesting article: "Earth Without
People":
What if humans suddenly went extinct?

PERCEPTION
IS NOT ALWAYS REALITY
OR ... WHY is a
T-ILLUSION?
This new interactive lesson is designed to combine
the intrigue of opitcal illusions with the processes of science,
so students begin to recognize the many natural illusions around
us and how science works to expose them.

What Came Before DNA? Scientists may soon reveal how
life began on Earth, by creating a primordial organism in the
lab. By Carl Zimmer
Pages 34-41. Reviews our current knowledge and proposals about
the process of life's origins on Earth, and discusses current
efforts to replicate the process in the laboratory.
Useless Body Parts. By Jocelyn Selim in the same issue,
pages 42-45. A brief listing and discussion of about 20 of the
many vestigial and atavistic structures in our body, along with
data about how many (or few) in our population have some of these
structures, and what their original functions may have been.
This content would be a useful addition to our "Blocks & Screws: Contrivances"
lesson.
Other items of note in this issue include:
Page 15: "In 1619 Lucilio Vanini was burned at the stake
for proposing that humans evolved from apes." (From the
Discover Science Almanac, page 397). Do you sometimes get the
feeling that our society might be slipping back in that direction?
Page 17: "How closely related are people to each other?
And how closely does our genome match up with those of other
primates?" Brief response by Jonathan Marks at University
of North Carolina.

HUMAN EVOLUTION: INTERPRETING
the EVIDENCE
An Approach to Teaching Human Evolution
in the Classroom
By Jeremy DeSilva, Boston Museum of Science and the
Dept. of Anthropology at Boston Univ.
Published in the American Biology Teacher, April 2004,
page 257.
AVAILABLE
ONLINE
Don't miss this excellent article. It would make a
very useful extension or alternative to our Skulls Lab and our Chronology Lab. It includes three
compatible full-page diagrams (suitable for overheads and handouts)
of provisional family trees, according to Tim White (a "lumper"),
Ian Tattersall (a "splitter"), and Meave Leakey (a
"no-lines splitter"), all based on 29 selected fossil
hominins (out of the thousands found), identified by their accession
numbers and currently assigned names.
The article is built around getting students to see and distinguish
the "facts" (discovered and dated fossils), from their
legitimately differing interpretations by experts in the field.
This is an excellent example for engaging students in seeing
and discussing important elements of science at work in the dynamic
field of paleoanthropology, including uncertainty and scientific
controversy, and the reasons behind these issues. Lots of good
teaching ideas.

EVOLUTION ENCODED
Scientific American, April 2004, page 84.
Here's a new resource to put in your DNA -
Evolution bag. New discoveries about the rules governing
how genes encode proteins have revealed nature's sophisticated
"programming" for protecting life from catastrophic
errors while accelerating evolution. By minimizing the effects
of any mutation, the code maximizes the likelihood that a gene
mutation will improve the resulting protein.

Additions
and Changes to the Varve Dating Lesson
Photo of the Green River shale as seen in Desolation Canyon
Scroll to the end of the lesson
Links to geological details and
confirmation of the validity of the varves.
Update of sources and costs for blocks of the shale and billets.
See "Other Resources", items 4-6, in the
Varves Lesson.
This lesson is an excellent hands-on way for students
to discover that our earth is very very old, a way which complements
the very accurate radiometric methods
with a combination of tactile experience and a little easy math.

NEW!
Hominoid Skull
Photos Available
These are full scale, color photos of 7 hominoids, 4 views each,
providing opportunity for more observation and measurement. Each
can be downloaded and printed at nearly full scale, then enlarged
to make classroom sets at full scale.
Full size skull replicas are far superior for use in our "SKULLS
LAB", but cost may preclude their use, These photos should
provide a reasonable substitute. |

EVOLUTION: The Triumph of an Idea
Another "page-turner" by
Carl Zimmer
Loaded with fascinating new insights and studies to share with
your students.
FINDING DARWIN'S GOD
Ken Milller, in his typically eloquent,
concise, and clear manner,
offers a most useful perspective to help deal with the inner
conflicts so often encounterd by students, and their teachers.
In both these books, as with the others in our list,
both evolution and the nature of science are explored
and explained in ways teachers can emulate. All of these books
can be reviewed and ordered (from NCSE) in our RESOURCES section
