TEACHING TOLERANCE
People have far more in common than any differences we may perceive (real or imagined). My community service
project supports that understanding by not discriminating against anyone on the basis of ancestry, ethnicity, race,
color, language, handicaps, age, appearance, socioeconomic situation, genetics, gender, sexual orientation, religion,
marital status, physical and mental health, veteran classification, intelligence, politics, or anything else; all persons are
accepted as fellow human beings, and I support the Americans with Disabilities Act (ADA), enabling equal access to
educational excellence. http://www.usdoj.gov/crt/ada/adahom1.htm
INTRODUCTION
If you're new to my website, I designed it as one web page using Microsoft Office Student and Teacher Edition, plus
Yahoo SiteBuilder, so that you can download it quickly (without needing a lot of RAM) and navigate easily through
photographs and text (displayed for online reading against a subdued plain background and centered with wide margins
down the middle of desktop and laptop computer monitors).
The Space Rocks project is described first, I. ASTRONOMY THAT FALLS FROM THE SKY, then there's a litany of
links in II. SUBJECT-RELATED EDUCATIONAL WEBSITES, lastly III. SPACE ROCKS WORKSHOPS provides an
overview and how to apply; after all that is a brief blurb about me.
COMMUNITY SERVICE
Space Rocks workshops are free and no academic, government, business, religious, political, or private funding is
requested; instead, please consider helping the hungry and homeless by supporting the Amos House soup kitchen
and shelters in Rhode Island www.AmosHouse.com
I. ASTRONOMY THAT FALLS FROM THE SKY
|
A ROCK TOUR WITH REAL ROCKS
Since 1987, the Space Rocks project has followed a traditional New England public school calendar so that workshops
are scheduled regularly, September through May, and for Summer space camps. Recently, the 'rock tour' was off to
Connecticut, back for two Rhode Island space camps, and then on to Otis Air National Guard Base in Massachusetts.
Applications are now being accepted for Spring 2010, Summer 2010, Fall 2010 and Spring 2011. Throughout 2009 we
celebrated the International Year of Astronomy. 400 years ago Galileo Galilei first turned his telescope toward the night
sky in 1609; both professionals and amateurs are still doing that right now.
It's been encouraging to work with thousands of enthusiastic students, teachers, and members of Civil Air Patrol and
other organizations from Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania,
Rhode Island and Vermont as we've studied together during Space Rocks workshops.
PIECES OF OUR SOLAR SYSTEM
The solar system has been likened to a pinball machine because some of its objects 'bump' into each other.
These 'impacts' may cause moving rocks in space to change course (similar to the equal and opposite reactions
of the ricocheting ball in the machine), however unlike the game's steel ball, and depending upon the angle and
force of impact, pieces of planets, moons, asteroids, and meteoroids may 'bounce' off in multiple directions,
some eventually reaching Earth and other celestial bodies as meteorites. Most meteorites come from asteroids
and as a brief introduction to those almost uncountable rocks that never formed into a planet during the
formation of our solar system, you can watch Dr. Neil deGrasse Tyson's PBS NOVA Science Now video about
asteroids at http://www.pbs.org/wgbh/nova/sciencenow/3313/01.html, either in your classroom, or as homework.
Public libraries often have available asteroid and meteorite VHS or DVD videos to borrow as well as online
computers to use for research.
WORKSHOPS
We introduce and explore meteorite science and history to encourage active student interest in all learning,
developing effective study skills, and staying in school through graduation in order to become well-informed
responsible citizens. Pieces of our solar system, older than the oldest Earth rocks (over 4 billion years old) are
brought into mostly urban elementary classrooms so that students can hold in their hands, for 'up-close and
personal' examination, specimens of: our Moon, the planet Mars, a comet nucleus, asteroids, and some tiny
chondrules (the first solid matter to accrete from the Sun's primordial solar nebula of gas and dust). One
meteorite even contains interstellar grains (stardust) blasted into space by the supernova explosion of another
star (in our galaxy) that lived and died far away and long ago before the Sun formed. Impact iridium sediment,
from an asteroid hitting the Earth 65 million years ago, and Triceratops fossils (among the last dinosaur species
at the time of that massive impact), are included.
Classroom workshops are adapted to each teacher's established curriculum and instruction plus school
schedules. Although inner-city intermediate elementary classes are my educational priority, whenever possible,
presentations are also planned for middle schools, high schools, colleges, and universities, plus after-school
programs, libraries, museums, observatories, planetariums, astronomy organizations, education conferences,
science camps, and other centers of lifelong learning.
Local media coverage informs the public about your experiences with rare rocks from space. A group-developed
written report, including photographs of involved students (with permission forms signed by parents or legal
guardians), could be published on a school Internet website for educationally sharing with others throughout the
World Wide Web.
Inquiry science (especially meteoritics), always a work in progress because it involves so many interrelated
researchable variables, requires continual updating to include the newest knowledge and to refine meaningful
questions; this project is no exception, therefore, informed discussion of all thinking from every perspective is
respected so together we can consider what we know, as well as what we don't know, and learn from both.
RESOURCES
The 18 meteoritic specimens pictured and described in detail below, Triceratops fossils, a Triceratops model, a
chalcopyrite Earth rock, Moon globe, Mars globe, magnifying glass and lab magnet, instructional display
pictures (for bulletin boards), study handouts, and color printed certificates of participation are all provided at no
cost to students, teachers, or schools.
THE BEST-PRESERVED MAJOR METEORITE IMPACT CRATER ON EARTH
|
These are two of my photographs at "Meteor Crater" near Winslow, Arizona. The shot on the left was taken looking through
the cockpit glass of our plane circling low and slow above the crater with veteran United States Air Force and commercial pilot,
Capt. Jim Cook. Strong thermals rising off the high desert below us caused our aircraft to buck up and down hundreds of feet,
but we continued studying this area's dynamic geology by flying next over nearby ancient volcanic craters (for comparison),
and then following the drainage of Canyon Diablo toward the Colorado River and subsequently the Grand Canyon where we flew
across that spectacular erosion.
IDENTIFYING A "METEOR CRATER" METEORITE IN YOUR HANDS
|
The scan above shows 17 rare, fragile meteoritic specimens (cut small) in clear individual boxes so that they can
be displayed inside one Riker Mount for examination with a laboratory magnifying glass. These fragments, along
with the two larger rocks and dinosaur fossils, remain on educational tour throughout the year; perhaps coming
soon to a school or library near you: descriptions of specimens that students ask about most often are
highlighted in blue.

the orbit of the planet Mercury; Allende, Mexico: stone meteorite containing interstellar grains (stardust) from the explosion
of another star before our Sun was formed; Murchison, Australia: stone that may be from a comet nucleus, predates our
solar system and has remained virtually unchanged since, contains elements that formed in different types of other stars,
in addition to amino acids unknown on Earth.

MORE SPACE ROCKS ARE AT BROWN UNIVERSITY
|
42 more space rocks (not touring area schools), in this study collection of 60, are at the NASA
Northeast Regional Planetary Data Center on the second floor of the Lincoln Field Building, main
campus, Brown University in Providence, Rhode Island. SpaceRocksWithDrLen.com donations to the
university also include a piece of alloy from a space-flown Soviet Soyuz cosmonaut spacecraft;
fragment of the first U.S. space station, Skylab; tomato seeds exposed to nearly six years of space
radiation in NASA's LDEF satellite; polystyrene spheres manufactured by astronauts aboard Space
Shuttle Challenger; and a Triceratops bone fossil (one of the last dinosaur species at the
Cretaceous-Tertiary mass extinction). NASA resources to study the entire solar system are maintained
here for teachers and students. http://www.geo.brown.edu/BrownNASADataCenter/Home.htm
65 million years ago, an asteroid, approximately six miles in diameter, hit Earth at an estimated speed of
50,000 to 100,000 miles an hour (as dramatically illustrated in this painting by artist for NASA Don Davis).
Scientists are still researching the details of what happened and the time frame over which they happened,
but geologic evidence indicates that a combination of natural effects killed off two-thirds to three-quarters of
all plants and animals, including the dinosaurs; school bus-size Triceratops was one of the last dinosaur
species. The world was rocked by shock waves passing all the way around our planet and possibly even
through it, superheated debris was thrown miles above the Earth and then rained back down making the
sky glow red hot while the air became fouled with poisonous gases and acid mist, Earthquakes shook the
ground and volcanoes erupted. A tsunami hundreds of feet high and moving at hundreds of miles an hour,
splashed over a huge area of North, Central, and South America. The global climate was changed
drastically, with temperatures at first becoming hotter, then dropping to freezing from the ensuing
day-and-night blackness of an impact winter. Sunlight was blocked out completely for months, until the
thick haze and dust gradually settled to the surface. A specimen in the Space Rocks study collection is
iridium sediment (a rare element on Earth, but common in meteorites) carried by the weather after this
impact and deposited worldwide at the K-T Boundary layer in the ground. The ancient impact site is the
Chicxulub Crater, five miles deep and over 100 miles wide; mostly under sea and sediment, but partially
overlapping land on the northwest tip of what is now the Yucatan Peninsula in Mexico.
THE LAST OF THE DINOSAURS
|
In this photograph are fossilized Triceratops fragments (Clockwise from top: tooth, rib bone, frill)
dug up by paleontologists during fieldwork in Wyoming and Montana. These pieces are displayed
in a Riker Mount so that students can hold specimens from one of the last dinosaur species on
Earth without the jagged edges crumbling and to avoid getting stone grit in their mouths or eyes.
Just over a century ago, at 7:17 A. M. on June 30, 1908, above the Tunguska River in a remote
area of Siberia, Russia, an aerial explosion flattened 800 square miles of forest below, leaving
80 million trees on the ground in a radial pattern pointing out from the center of the downward
blast. This was followed by a firestorm while black molten metal rain fell. (The old photograph
above, from Leonid Kulik's early expeditions to the site, shows fallen trees.) There is still some
debate about what happened, despite local first-hand accounts, but it is generally agreed that a
rock from space approximately 120 feet across, weighing 200 million pounds, travelling at over
33,000 miles an hour, plunged into Earth's atmosphere. At about 28,000 feet altitude, the
extreme heat (44,000 degrees Fahrenheit) of atmospheric compression caused the rock to
fragment and mostly vaporize, producing a spectacular fireball in the sky. The Space Rocks
collection includes one of the metal rain drops and a piece of bark from a spruce tree knocked
down by the Tunguska Event.

SOME STUDENT AND TEACHER SPACE ACTIVITIES
|
Follow NASA's Dawn spacecraft all the way to Vesta in the Asteroid Belt
|
NASA DAWN mission, 2007-2015: In the photographs above, the Dawn spacecraft, atop a Delta II Heavy
launch vehicle, arched across the blue morning sky from Cape Canaveral Air Force Station, Florida, on
September 27, 2007, as it headed for the blackness of space and its first stop around the asteroid Vesta
to study the formation history of our solar system. One meteorite specimen in the Space Rocks study
collection is a small piece of Vesta that was knocked off into space. Many students and teachers are
following Dawn's eight-year, 3.2-billion-mile mission to the heart of the Asteroid Belt (where most
meteorites originate), because asteroids contain matter that is virtually unchanged since our solar
system was forming, (and partly because during preparations in 2006, we were given the opportunity to
have our individual names documented in the spacecraft). Dawn, carrying our names, will be the first
space voyager to attempt orbits around two different bodies in space: first at the brightest asteroid, Vesta,
in 2011 and subsequently at the largest asteroid, Ceres, in 2015. http://www.dawn-mission.org/index.asp
OUR NAMES ON MARS: NASA's Phoenix spacecraft traveled 422 million miles through space following
its launch from the Cape Canaveral Air Force Station on a Delta II rocket, August 4, 2007, and reached
Mars, May 25, 2008. This mission is special to me because: Phoenix touched down in the north polar
region on Mars and I've been in the ice of the north polar region on Earth, a specimen in the Space Rocks
tour collection is a Martian meteorite, plus NASA had already recorded our names (Marguerite & Dr. Len)
on board so, sort of vicariously, two retired school teachers have gotten to Mars.
NASA STARDUST@home: 2006-2007, many of us in education helped U.C. Berkely and NASA Johnson
Space Center scientists identify interstellar dust grains, from faraway stars, by conducting millions of
visual examinations of digital images using online microscope technology and personal computers at
home or in school. This star dust (largest particle size only a few microns) speeding through space at
over 56,000 mph impacted collector tiles on the NASA Stardust spacecraft and was captured in aerogel.
The mission's Delta II launch vehicle lifted off from Cape Canaveral Air Force Station, Florida, February 7,
1999, and traveled for 7 years and nearly 2 billion miles across our solar system before its return capsule
was recovered back on Earth, January 15, 2006.
STARSHINE satellites: From 1998 to 2001, I worked with students grinding and polishing metal mirrors
for three Project Starshine satellites: Starshine I was deployed by STS-96 Space Shuttle Discovery
astronauts in 1999, Starshine 2 was deployed by STS-108 Space Shuttle Endeavour astronauts in 2001,
and Starshine 3 was sent into a polar orbit on board an Athena I, the first launch by NASA from Kodiak
Island, Alaska, in 2001.
PROJECT COMET CHASER: My Civil Air Patrol duties have included (among many other educational,
airshow, and flying opportunities), being Liaison Officer for the RIASEC Viper Dart rocket launch (the first
to space from Rhode Island) carrying a school-made experiment into the annual Leonid Meteor Shower.
3,000 students and teachers participated rather 'briskly' in this 1999 Aviation and Space Education Day
outdoors in mid November near the ocean.
NASA SEEDS in space: The 1990 SEEDS experiments provided us opportunities for growing (but not
eating) tomato plants in our classrooms on Earth from seeds exposed to radiation while orbiting in space
aboard NASA's LDEF satellite. LDEF was deployed in 1984 by STS-41C Space Shuttle Challenger
astronauts at an altitude of 275 nautical miles and remained in space for 5.7 years completing 32,422
Earth orbits. LDEF was retrieved in 1990 by STS-32 Space Shuttle Columbia astronauts after the
satellite's orbit had gradually decayed to 175 nautical miles. (Years later, both the Challenger and
Columbia orbiters, with all astronauts then on board, were lost during other missions.)
SOME SELECTED BOOKS AND PERIODICALS

Listed first are a few introductory astronomy and meteorite books; we don't need math or physics
backgrounds to read them. These are often available in your school library, public libraries, or
through interlibrary loan systems. If you like to highlight and underline, as I do, you can buy them in
paperback (new or used) at local and online bookstores. This will save you money and also save
you from librarian angst because you won't be writing in a borrowed copy. (Always look for the very
latest edition, as new scientific learning is added during revisions.)

SOME OF MY FAVORITE SCIENCE EDUCATORS
|
Dr. Stephen Hawking: Professor Hawking writes both technical and popular books about science and has
a worldwide following. I went to meet him, before an evening lecture in 1999, as I admire his intellect. I
came away from our meeting inspired by his humanity because, during that day, he'd been visiting patients
in Boston Children's Hospital, as a role model for not giving up. His website at Cambridge University is:
http://hawking.org.uk
Dr. Carl Sagan: The late Professor Sagan actively shared his diverse interests with the general public, as
well as with his students at Cornell University. I enjoyed reading his books, watching him on television,
and found such energy in his enthusiasm for education. In the middle of his 1980 Cosmos series on PBS,
I wrote to him; he was kind enough to reply with a detailed letter. In the following quotation, he calls our
attention, scientifically, to the fact that human beings have more in common than any differences: "Every
person on Earth shares 99.9 percent of the same DNA sequences." The memorial website devoted to his
multifaceted work is: http://www.carlsagan.com/
Dr. Eric Chaisson: Professor Chaisson's best-selling astronomy textbook (listed above) is available in an
edition for math and physics students and an edition for the general reader. To conclude a 1982 guest
lecture that I attended, he took questions from the audience. I felt self-conscious, as an education major,
because I worried that students majoring in science, and their faculty, might find my question rather
pedestrian, so I made it as scientifically succinct as possible. Not only did he respond to my query about
the nature of the universe, but first he surprised me by explaining the question to everyone else. His
website at Tufts University is: www.tufts.edu/as/wright_center/eric/ericpage.html

III. INTERDISCIPLINARY SPACE ROCKS WORKSHOPS
|
WE PLAN TOGETHER
A PDF of the Space Rocks adaptable workshop plan is e-mailed to each teacher as we coordinate, so you can
determine the extent that our multidisciplinary study of rocks from space may be integrated into your
established standards-driven curriculum and instruction.
Traditional lesson/unit plans are adapted into a concise hands-on, minds-on sequence of I. PREPARATION,
II. PRESENTATION, and III. CONTINUATION to enhance guided learning processes, which consider our
whole world and its place in the ever-changing universe, through SCIENCE: All meteorites are rocks
knocked off other planetary bodies out in space and eventually falling to Earth where we can examine them
directly for scientific evidence about the formation and history of planets, moons, asteroids, meteoroids, and
comets that orbit our Sun (an average star and the closest to us in the Milky Way galaxy). In addition to
space rocks that may impact Earth again, people affect Earth's condition every single day. We are fortunate
to live on Earth, the only planet in this solar system's Goldilocks Zone which is 'just right.' Can you think of
ways that each of us can help care for our home planet? MATH: We use ordinary numbers regularly in
school and in our daily lives, but to study outer space we must use huge numbers to calculate extraordinary
distances spanning trillions of miles, ages in billions of years, and hypersonic speeds in many thousands of
miles an hour. SOCIAL STUDIES: Where (or what) in the world has a space rock hit in the past? You can
locate known sites on an Earth globe or wall map, study the area's geography, and look for an impact crater.
History, culture (especially the rights of women), schooling, government and current events of the local
country's people may be compared with the United States to better understand our world's diversity.
ART: Reviewing photographs, films, videos, paintings, and other representations of famous meteors and
meteorites, often inspires us to create our own interpretations. LANGUAGE: We all apply reading and
writing skills when we conduct research using libraries or the Internet (carefully checking and citing multiple
scholarly sources), reflect on our ideas, and orally explain our reasoning.
Students are encouraged to save copies of all in-class work, homework assignments, and activity
photographs for their individual portfolios. To demonstrate what we've learned together, pupils can choose
examples of their best efforts and through critical thinking discuss as a group how selections represent
understanding. A class-produced reference portfolio, for your library, would feature these selected learning
artifacts. Sharing with our family what we've studied, can encourage positive interaction between our home
and our school, as well as meaningful conversation if we turn off the television set and video games.
APPLYING FOR A SPACE ROCKS WORKSHOP IN YOUR CLASSROOM

ABOUT ME
My teachers over the years (some with dogged determination), taught me how to learn; I didn't always appreciate
it, but would eventually. I began Kindergarten as a timid student and reluctantly trudged through thirteen years of
public school. After serving honorably on active duty in the United States Coast Guard (International Ice Patrol), I
was eligible for educational funding of veterans under the G. I. Bill, but what college would ever want me?
Fortunately, my home state of Rhode Island had just opened a new community college where an apparently
adventurous administrator actually accepted me into the world of higher education; little did she know how long
I'd stay.
As the first person in my family to go to college and only the second one fortunate enough to even graduate from
high school (just barely), I was in an exciting new environment. However, if it weren't for financial assistance in
the forms of a scholarship, a fellowship, tuition waivers, several graduate assistantships, on-campus
employment, off-campus employment, United States government guaranteed loans, and that G. I. Bill which
started it all, I'd have been another in our long familial line of mill workers (men and women who, after work,
read books from their local public libraries).
I absolutely loved my 23 years as a full-time and part-time college student earning an A.A. at the Community
College of Rhode Island, B.A., B.S., and M.A.T. degrees from Rhode Island College, plus a University of
Connecticut Ph.D. in education, reinforced by some honor societies, encouragement from my wife (a school
teacher for 31 years), and our children. With a doctorate in my pocket, I felt free to study any subject on my own,
partly because I chose to, but more importantly because I knew how to. At last, I appreciated having been taught
how to learn by all those teachers along the way. In addition, one of my own graduate students pointed out
(tactfully) that by then I had more letters 'after' my name than there are 'in' my name.
Everything interests me, so I considered every possibility in developing a community service postdoctoral study
project through which I could encourage students to enjoy learning. I'd always found astrophysics and space
exploration fascinating. Going into space was science fiction when I was a kid, but during the years I was in
school it had moved to the forefront of active science, so I launched (metaphorically albeit enthusiastically) into
study of those pieces of our solar system that I could actually get at because they fall from the sky. With the
generous assistance of two international meteorite specialists, I was able to purchase, one by one, a
comprehensive collection of sixty small-size specimens to examine and hand around to students during school
workshops. Of course, I couldn't study meteorites very long without exploring (metaphorically again) planets,
moons, asteroids, comets, dust, impacts and DINOSAURS!
At the same time as I was hitting the books (the last clichéd metaphor; I wouldn't really hit a book because I like
them so much), I earned an FCC license to produce and host my own public radio live educational talk shows
and classical music programs for four years, worked for six years as a photographer, was a Student Teaching
Supervisor, Visiting Lecturer and Adjunct Professor in education at a college and two universities in three states
for over twenty years, and became a Lt. Colonel in Civil Air Patrol aerospace education. In my spare time I
planned tours of historic Civil War sites around the country and made Zen rock gardens.
Now, as a volunteer educator, I get to bring space rocks and dinosaur fossils to schools and other centers of
lifelong learning so that we can study them together, plus the most observant students get to earn extra credit for
noticing instances of missspelling. Additionally, I share some social comments about living.
-We can all learn much more at our public library; in the United States, knowledge is free to everyone.
-We are responsible for what we do, and sometimes for what we don't do.
-Only a fool wants to hear just his own ideas repeated back to him.
-We can't use our brains on drugs; that's why it's called dope.
-Without integrity, we have no credibility.
-Hate hurts, both ways.
-We can do better.

Shown here are two bare rocks, on the ground, that students examine during a Space Rocks workshop using basic
science skills (plus our physical senses) to determine which is a space rock and which is an Earth rock. These
specimens can be easily compared by weighing them on a gram scale, lowering each into a graduated cylinder to
measure water displacement, looking at them under a magnifying glass, holding a small magnet on a string next to
them, feeling them with your hands, smelling them with your nose, and tapping them on a lab table to hear if they
sound different. (It's safer that we not use our sense of taste for checking out unfamiliar substances.) Extensive
ongoing research estimates that "Meteor Crater" was formed when a huge meteoritic mass, more than 130 feet
wide, weighing over 100,000 tons, traveling through the air at more than 35 times the speed of sound, slammed into
the hard desert and violently disintegrated. (For velocity comparison, NASA's Space Shuttles fly at Mach 25.) The
meteorite was named after nearby Canyon Diablo and its impact site is called the Canyon Diablo Crater or Barringer
Crater by meteoriticists, but we find it on the Internet under its popular name at: http://www.meteorcrater.com/











Hubble Space Telescope photograph of Mars: NASA





Down on the ground, my picture on the right is the view across the crater, rim-to-rim. Dr. David Roddy, USGS, guided us
among the boulders ejected by meteorite impact and taught us to eat Popsicles when we got back to indoors air conditioning,
yet after hours out in the sun I looked like a French Fry and felt like a refried bean. Our field trip went well, other than the day
that I lost my footing while perched at the edge and fell over backwards protecting my camera. Despite a bones-on-stones rib
separation that I still remember in damp weather, I managed to laugh it all off (at least in front of the witnesses) until I could get
to a chiropractor. Over 150 impact craters around the world have been documented so far, but this one is the first-identified and
best-preserved major impact crater on Earth; most of the others are severely eroded from millennia of weathering. After
49,000+/-300 years, this crater remains approximately 4,100 feet wide and 570 feet deep, with a fine visitors center and
museum right beside it for you to appreciate in person. Nearly three decades prior to our visit, the late Dr. Roddy trained
NASA astronauts here (most of them without stumbling or fumbling a camera) before their Apollo missions to gather geologic
specimens in craters on the Moon.
