THIS SPACE ROCKS WEBSITE
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 scroll easily down through photographs and text (displayed for online reading against
a subdued plain background with margins on desktop and laptop computer monitors).
The Space Rocks project is described first, 1. Student preparation: ASTRONOMY THAT FALLS FROM THE SKY, then
there's a litany of links in 2. SUBJECT-RELATED EDUCATIONAL WEBSITES, lastly 3. PLANNING CLASSROOM
WORKSHOPS provides an overview for teachers and how to apply; after all that is a brief blurb about me.
Space Rocks workshops are free to public schools and public libraries; no academic, government, business,
religious, political, or private funding is requested; instead, please consider helping hungry and homeless people

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
usually scheduled for September through May. 'Rock tour' presentations are mostly local (I'm in Rhode Island); sites farther
away require special advanced travel arrangements. Applications are now being accepted for the fall 2013 semester,
spring 2014, fall 2014, and spring 2015.
It's been encouraging to work with thousands of enthusiastic interested and interesting students, teachers, librarians,
members of Civil Air Patrol and other educational 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' (often violently) 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 rocky planets, moons, asteroids, and meteoroids may 'bounce' off
in different directions, some eventually reaching Earth as well as other solar system bodies as meteorites. The
ASTRONOMY THAT FALLS FROM THE SKY link (above) offers a brief introduction (either here online or as a
paper printout to keep) so that you'll know what we're talking about in the Space Rocks workshop. Public
libraries often have available asteroid and meteorite videos to borrow as well as computers online to use in the
library for Internet research (plus all those books on the shelves and through Interlibrary Loan!).
We introduce and explore meteorite science and history to encourage active student interest in all learning and
developing effective study skills while 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 schools and public libraries 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 my educational priority has been inner-city intermediate elementary classes,
presentations are also planned for middle schools, high schools, colleges and universities, plus after-school
programs. For libraries, museums, observatories, planetariums, education conferences, space camps, and
other centers of lifelong learning workshops/presentations are adapted to the interests and needs of the group.
Local media coverage informs the public about your experiences with rare rocks from space. A written report,
including photographs of involved students (with permission forms signed by parents or legal guardians), can be
published on a school or library 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.
The 18 meteoritic specimens pictured and described in detail below, Triceratops fossils, a Triceratops model, a
chalcopyrite Earth rock, magnifying glass and lab magnet, instructional display pictures (for bulletin boards),
study handouts, plus color printed certificates of participation are all provided at no cost to students, teachers,
schools and publicly-supported free libraries open to everyone (one of our greatest freedoms in the United States).
|THE BEST-PRESERVED MAJOR METEORITE IMPACT CRATER ON EARTH
These are two of my photographs at "Meteor Crater" near Winslow, Arizona. The aerial shot was taken looking through
the cockpit glass of our plane circling low and slow above the crater with commercial and United States Air Force
Vietnam Veteran pilot, Capt. Jim Cook, DFC. I was glad that my friend in the left seat has over twenty-thousand flying
hours, because strong thermals rising off the high desert below us caused our aircraft to buck up and down hundreds of
feet demanding a lot of hands-on piloting. We continued studying the area's dynamic geology by cruising next over nearby
extinct volcanic craters (for comparison), landing on a small air strip in Marble Canyon, and then following the eventual
drainage of Canyon Diablo into the Colorado River and subsequently the Grand Canyon where we flew across that
|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 the specimens that students ask about most often are
highlighted in blue.

|MORE SPACE ROCKS ARE AT BROWN UNIVERSITY
|42 more specimens (not touring area schools), in the Space Rocks study collection of 60, are at the
NASA Northeast Regional Planetary Data Center on the second floor of 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 educators 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. Our planet vibrated like a bell being rung from impact shock waves that passed all the way around
the Earth and possibly even through it, superheated debris was thrown miles above the world 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 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 metal element on Earth, but common in meteorites) carried by the weather after
this impact and deposited worldwide at the geologic 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,
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.
At 7:17 A. M., 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, is from Leonid
Kulik's early expeditions to the site.) There's still some debate about what happened, despite
local first-hand accounts, but it's most probable 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
|NASA's Dawn spacecraft orbited Vesta in the Asteroid Belt, 2011
|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 put in the spacecraft). Dawn, carrying our names, is the first space voyager to
attempt orbits around two different bodies in space: first at the brightest asteroid, Vesta, having arrived
July 15 PDT, 2011 (and 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 Lt. Colonel 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 breezy 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 after, both the Challenger and
Columbia orbiters, with all astronauts then on board, were lost during other missions.)

|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:
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 T.V. 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 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 honored me by explaining my question to everyone else. His website
at Harvard University is: https:www.cfa.harvard.edu/
Lately, I've been trying to follow the work of particle physicists Dr. Lisa Randall and Dr. Brian Cox at CERN,
where the Higgs Boson has been discovered and they seek to explain the universe in detail.

|III. PLANNING CLASSROOM WORKSHOPS
WE PLAN TOGETHER
All educators need to do in preparation is to click the link below and read the introduction file so you can
determine how extensively an adaptable Space Rocks workshop will integrate into your established
standards-driven curriculum and instruction. Your students should subsequently read the same file before the
workshop: Astronomy that falls from the sky 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 can 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 our solar system's
Goldilocks Zone which is 'just right'. Let's 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 women's equality), 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 (and the ways people act). ART: Reviewing representations of famous
meteors and meteorites through photographs, films, videos, and paintings, can inspire 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 peer-reviewed scholarly sources), reflect on our ideas,
and orally explain our reasoning.
Students are encouraged to save copies of all 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 school library, (or community public library) would feature these
selected learning artifacts. Sharing with our families what we've studied, may encourage positive interaction
between our home and our school, as well as meaningful conversation if we turn off the television and radio.
APPLYING FOR A SPACE ROCKS WORKSHOP IN YOUR CLASSROOM OR LIBRARY
Once you've read through this web page, considered your school or library schedule and how you'd like to include
a Space Rocks workshop, request an application by clicking this link: Marguerite.DrLen@yahoo.com and I'll

|Close-up of our Moon by the Apollo 17 astronauts: NASA
ABOUT ME ( I want to know why I want to know.)
My best teachers over the years (some with dogged determination), taught me how to learn; I didn't always
appreciate it immediately, but would eventually. I began Kindergarten as a timid student and reluctantly
trudged through 13 years of public school. After serving honorably on active duty in the U.S. Coast Guard
(International Ice Patrol; once right over the Titanic sinking site), 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 in that world.
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 a
combination of scholarship and fellowship financial assistance, 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 (where I first started to learn how to learn), 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 national honor societies, encouragement from my wife (a school teacher for 31 years), and our
children (I hope). In addition, I was a Coast Guard Auxiliary Flotilla Commander, became a Lt. Colonel in
Civil Air Patrol aerospace education, and in my spare time planned tours of Civil War historic sites around
the country and made Zen rock gardens.
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 my
best 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
project through which I could continue studying indefinitely and at the same time ‘give back’ by
encouraging public school 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'd been 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 meteoritic specimens to examine and hand around to students
during school and library workshops. Of course, I couldn't study meteorites very long without exploring
(metaphorically again) asteroids, comets, planets, moons, 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 educational talk
shows and classical music programs for four years (and got to change my name), worked for six years as
a photographer and was a Student Teaching Supervisor, Cooperating Teacher, Visiting Lecturer and
Adjunct Professor in education at a college and two universities in three states for over twenty years.
However, I found teaching college to be not nearly as intellectually stimulating as being a college student.
Now, as a volunteer educator (retired teacher), I bring space rocks and dinosaur fossils to schools,
libraries and other centers of lifelong learning so that we can study them together. 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 do not 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 flew 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/

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 the massive 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 of the crater 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 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 extensively 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 had trained NASA astronauts here (most of them without stumbling or
fumbling a camera) before their Apollo missions to gather geologic specimens in impact craters on the Moon.
