"Cross-post" from EPA Nonpoint Source Electronic Bulletin Board.

"Effluent toxicity evaluations" are a hot topic in the
environmental world and a lot of basic research is still going
on.  There seems to be no reason why some of this research could
not be done by high-school or even middle-school biology classes.
Chronic toxicity studies often run 90 - 180 days, providing a
rather nice fit in the school term.  And the students may be
energized by the opportunity to do something "real."

Subj: WHO'S A FATHEAD?               Conf: (4) RESEARCH
    USE OF AQUATIC PLANTS IN EVALUATIONS OF EFFLUENT TOXICITY:

    The use of aquatic plants in effluent toxicity evaluations is
uncommon despite the availability of test methods and numerous
recommendations for their use.  It is frequently assumed that
aquatic plants are less sensitive than animal test species;
invertebrates and fish are often used as surrogate data bases.

    A study at ORD's Gulf Breeze laboratory evaluated animal
toxicity tests in providing "safe" concentrations for in-stream
periphyton.  The toxicity of several samples of a treated
municipal effluent were determined during 5-month tests to
monitor short-term changes in periphyton photosynthesis
(carbon-14 uptake) and effects on young production and survival
of cultured daphnids and the fathead minnow.

    The effluent was seldom acutely toxic to Daphnia magna and
the fathead minnow but was consistently acutely and chronically
toxic to Ceriodaphnia dubia.  Significant inhibition and
stimulation of periphyton photosynthetic activity occurred at
concentrations of 6 to 39% effluent.

    Periphyton photosynthesis was a more sensitive effect
parameter than animal survival and in some cases than
Ceriodaphnia reproductive performance.  Results indicate that
effluent toxicity tests conducted routinely with daphnids and
fish may not be sufficient to protect the aquatic flora in
receiving waters. Therefore, estimates of phytotoxicity are
required for effective risk assessments for effluents.

    For more information call Dr. M. Lewis at the Gulf Breeze
laboratory.  (904)934-9382

Where we come from, we don't consider our animals weird at all, except

superb 6-part series called "Nature of Australia", winner of scads of
prizes, produced by our own ABC (that is the Australian Broadcasting
Corporation, a gov't-owned body, like the BBC).

If you like, I can check out details on prices for you, but watch out --
we use PAL TV, and firmly believe that NTSC stands for Never Twice the

Have you considered taking your class Whale Watching? I know of a couple of 
teachers who took their classes out on a whale watching cruise, and saw a lot 
of whales. We have one area in the Bay of Fundy off Brier Island on the North 
Shore, that can actually guarantee that you will see whales.

The Glooscap Trail is named after the Micmac indian god/hero Glooscap, who 
lived in this area. Legend has it that he lived on the Blomidon mountain 
overlooking the Chignecto Bay. The five Islands which the Five Islands 
Provincial Park are named after are supposed to be clumps of mud Glooscap 
threw at his arch enemy the beaver.

Is there a Glooscap in the legends of an American native nation as well? 

My class (grade 6) is doing a Social Studies/Language Arts unit on our 
Province, and later on we will be doing an extensive study of the Micmac 
peoples, so although I am no expert, I am learning a lot about both topics, 
and am more than happy to answer any questions about either.

G'day Robyn and Nicole -- just caught up with your request for information 
re bats.  If you'd like some info on Australian bats, give me a yell on
this conference area, and I'll gather some together.  We have both fruit
bats and insect-eating bats out here, and our fruit bats (known as "flying 
foxes") are a bit of a pest at the moment.  A colony of them has taken
over part of the Royal Botanic Gardens, and they are actually causing
damage to some of the trees there.  The trees are v. old and have heritage 
value, the bats are a protected species, and so you can see the mess we're 
in.  At the Australian Museum where I work, sme of us enjoy watching the
bats flying over at dusk as they spread out from their main roosting
places to gather food from people's fruit trees.
In tiday's local paper, somebody suggests planting garlic in the Gardens
on the ground that it gets rid of vampires -- can you spot the error in
what they said?

You asked:

You might try the book _Chaos, Fractals, and Dynamics: Computer
Expertiments in Mathematics_ by Robert L. Devaney. I have it listed in
the Dale Seymour Secondary Math Catalog for $19.50. Part of the
description states:

"In this book, one of the leading mathematicians in the study of chaos,
fractals and dynamic systems presents a lucid intro. to these ...new
topics. Students learn through a combination of hands-on computer
experimentation and precalculus mathematics. They are guided through a
series of graphics experiments that produce images of Julia sets, the
Mandelbrot set, and fractals. {..} Includes short BASIC programs, so
even students with no computer expertise can use them..."

Hope this helps.

One idea you might consider is to get rid of categories like Algebra II

Yes, I did consider that. And I suggested it to my dept. head. He seems
to feel that it is a good idea, but that our
school/area/community/parents/admin/whoever  aren't ready for it yet.

Anyway, I'm not going to try to convince him at this point. I have LOTS
of ideas how great it could be if we integrated the entire three year
Alg.1/2 and Geometry sequence. But it would be a lot more work at this
time than revising our own Geometry course. And there would be a LOT of
opposition to it at our school at this time. And I just don't have the
energy to be the only crusader in an uphill battle that is foredoomed to
failure.

Which part don't you understand? Each part of a triangle has a name (in trig, anyway).

o is actually the greek letter for Feta (sp?); it's an o with a dash thru it.
You'll need a scientific calculator too.  Feta is the angle in that corner.

There are three basic formulas

   sine feta  = opposite over hypotenuse
 cosine feta  = adjacent over hypotenuse
tangent feta  = opposite over adjacent

Now ask me what all that means! <grin>

After several days, nobody seems to have mentioned a public domain
program for DOS machines called FRACTINT.  The last version I have seen
is FRACTINT 15, and the writers say they don't want your money, they
want your admiration, and rightly so, too!  It contains all of the
formulas, since you have the chance to get in and twiddle and tweak the
parameters.

I understand it is available through Compuserve, but out in Australia,
our friendly local system supplies things like that at no price, other
than the time taken to watch ZIPped files dribbling through the 2400
baud modem.  Maybe you should ask around a bit, and see what is
available round Winnipeg,
