REAL
QUESTIONS ASKED IN SCIENCE CLASSES
Are the rivers flowing up the mountain or down the
mountain?
Is that the ocean? (Asked while on a field trip to
Marine Lab Beach on Guam (a small island in the
Pacific).
How can the river be flowing north? That's uphill!
How can mass wasting be an agent of landscape
formation on the Moon? The Moon has no gravity!
How do I get water into this beaker?

immersion geologists
Total immersion geologists: Are you totally obsessed
with geology? If so, then you are a total immersion
geologist. Here are the ten warning signs:
1. You judge a restaurant by the type of decorative
building stone they use rather than their food.
2. You manage to turn any conversation into a
discussion of geology, as in: "What did you think
of that Superbowl game last night?" "I must
have missed that conference. Who sponsored it?
Geological Society of America?"
3. You refuse to let nightfall stop your field
excursions and continue looking at the outcrops using
the headlights of your field vehicle.
4. You like rock music only because it's called
"rock" music.
5. You will try to claw through the water flowing in a
stream to get a better look at the bedrock at the base
of the channel.
6. You will walk across eight lanes of freeway traffic
to see if the outcrop on the other side of the highway
is the same type of rock as the side you're parked on.
7. You name your children after rocks and minerals.
8. You're not sure if you have children.
9. You view non-geologists as subhuman.

ANSWERS FROM EARTH SCIENCE EXAMS
The terrestrial planets are much larger than the gas
giants.
Wegener found matching bedbugs on opposite sides of
the Atlantic.
The main problem associated with limestone aquifers is
Lyme disease.
We don't have rock salt on Guam because that forms
from from evaporation of oceans and we don't have
oceans on Guam.
Erie, Pennsylvania has no volcanoes because it's too
cold there.
The most important agent of landscape formation on
Guam is greyhounds - they are intelligent.
We know that the sun is much farther away from us than
the moon is, because we can see stars between us and
the sun, but not between us and the moon.
The rear end of a trilobite is called a trilobutt.
Geology
word plays
Several
short geology plays on words
Okay, if you are a real geologist, you probably enjoy
transferring geology vocabulary into everyday
situations. For example, if you agree with what
someone has said, you may say, You breccia! or My
sediments exactly!
And if you are not pleased with the person's
statement, you may resort to the old:
That's not gneiss!

Old man Stokes was a gentleman fine

THE
CHEMIST'S RECIPIE FOR CHOCOLATE CHIP COOKIES
The following recipie for chocolate chip cookies
recently appeared in Chemical & Engineering News
(C&EN, Jun 19, 1995, p. 100). It was attributed to
Jeannene Ackerman of Witco Corp.
Ingredients:
1. 532.35 cm3 gluten
2. 4.9 cm3 NaHCO3
3. 4.9 cm3 refined halite
4. 236.6 cm3 partially hydrogenated
tallow triglyceride
5. 177.45 cm3 crystalline C12H22O11
6. 177.45 cm3 unrefined C12H22O11
7. 4.9 cm3 methyl ether of
protocatechuic aldehyde
8. Two calcium carbonate-encapsulated
avain albumen-coated protien
9. 473.2 cm3 theobroma cacao
10. 236.6 cm3 de-encapsulated legume
meats (sieve size #10)
To a 2-L jacketed round reactor vessel (reactor #1)
with an overall heat-transfer coefficient of about 100
Btu/F-ft2-hr add one, two, and three with constant
agitation.
In a second 2-L reactor vessel with a radial flow
impeller operating at 100 rpm add four, five, six, and
seven until the mixture is homogeneous.
To reactor #2 add eight followed by three equal
portions of the homogeneous mixture in reactor #1.
Additionally, add nine and ten slowly with constant
agitation. Care must be taken at this point in the
reaction to control any temperature rise that may be
the result of an exothermic reaction.
Using a screw extrude attached to a #4 nodulizer place
the mixture piece-meal on a 316SS sheet (300 x 600
mm). Heat in a 460K oven for a period of time that is
in agreement with Frank & Johnston's first order
rate expression (see JACOS, 21, 55), or until golden
brown.
Once the reaction is complete, place the sheet on a 25
deg. C heat-transfer table allowing the product to
come to equilibrium.
