"Introduction to Aerodynamics
and FoilSim"
This session demonstrates how grades 7 -12
math and physics teachers can use basic aerodynamic theories, incorporated
into interactive lessons, to enhance classroom instruction. It includes
understanding the forces that affect an aircraft. The slides used
in the presentation are available at the Beginner’s Guide to Aerodynamics
(BGA).
The workshop also introduces the basic classroom uses of FoilSim,
a simulation that determines the airflow around various shapes of
airfoils. As students change the parameters of airspeed, altitude,
angle of attack, thickness and curvature of the airfoil, and size
of the wing area, the software calculates the lift, allowing students
to learn the factors that influence lift. One computer is required
for each two workshop participants. Supplies needed: paper, pens
or pencils, and scissors. Tom Benson, NASA researcher and creator
of FoilSim and the BGA, is the workshop presenter.
"Introduction to Propulsion and EngineSim"
This session demonstrates how grades 7 -12
math and physics teachers can use basic propulsion information,
incorporated into interactive lessons, to enhance classroom instruction.
It includes understanding the reasons for different types of engines.
The slides used in the presentation are available at the Beginner’s
Guide to Propulsion (BGP).
The workshop also introduces the basic classroom uses of EngineSim,
a simulation that explores the ero-thermodynamics of a Jet Turbine
Engine. Students can explore the different types of jet engines
and how they work. They can change the operating conditions and
even design their own turbine engine. One computer is required
for each two workshop participants. Tom Benson, NASA researcher
and creator of EngineSim and the BGP, is the workshop presenter.
"Using NASA Educational Internet Sites
in the Science Classroom"
This session shows science teachers of grades
3-8 and 9-12 how to use NASA Internet sites to enhance their curriculum.
Online interactive projects and exercises are included, and time
is allotted for questions and answers. One computer with live
access to the Internet is required for each two participants,
who should have previous experience with a Web browser. Carol
Galica, Glenn Learning Technologies Webmaster, is the workshop
presenter.
Student Workshops:
"Aeronautics"
Aeronautics has been and will remain a key
focus in NASA’s research and development in to the 21st century.
This workshop utilizes a hands-on, minds-on approach to the topic
of aeronautics and how technology has influenced our society.
History and principles of flight, as well as new advances in aeronautics,
are discussed and illustrated. In the workshop, aeronautical
maps are used to teach math skills and geography. Participants
access NASA Internet resources or watch as the resources are demonstrated,
then word as teams to produce effective products. Available
for grades K - 12.
"Aircraft Safety and Icing Research"
In an effort to improve aircraft safety
by reducing the number of in-flight icing events, NASA Glenn conducts
flight tests using their icing research aircraft. This workshop
debriefs the audience on the results from one such program, the
NASA/FAA Tailplane Icing Program. The presenter engages
the audience in discussions of basic aircraft flight mechanics
and the function of the horizontal tailplane, as well as the effect
of ice on airfoil (wing or tail) surfaces. A brief video
of actual flight footage is shown. The video illustrates
the flow at the tailplane with and without an ice shape and provides
a view of the pilot’s actions/reactions and the horizon.
Available for grades 8 - 12.
"High Speed Flight"
When people think of supersonic flight,
they think "really fast"! This workshop presents the history of
flight and how an airplane and its engine "work." Emphasis is
on "high speed" flight, including the difference between subsonic
(or what everyone knows as today's airplanes) to supersonic and
hypersonic flight. The presentation includes a short video called
"Super Plane" and a brief history of the United States' supersonic
programs, ending with the current High Speed Research Program
at NASA Glenn Research Center. Available for grades K -
12.
"History of Humans in Space"
This presentation traces the human exploration
of space beginning with the single orbit flight of Yuri Gagarin
in 1961. Problems to be overcome during launch, orbit, space walking,
rendezvous docking, and reentry are discussed. American's
Mercury, Gemini, Apollo, Skylab, and Space Shuttle programs are
described, as well as the Russian Vostok, Voskhod, Soyuz, Salyut,
and Mir programs. Current plans for the International Space Station
are included. Video clips and scale models of the spacecraft
and boosters are used in the presentation to provide a sense of
scale. Available for grades 4 - 12.
"History of Rocketry"
This presentation focuses on the early history,
development, and future of rocket propulsion. It covers
propulsion from the development of rocketry in China over 1000
years ago to the future of human exploration of the outer Solar
System.
The interactive and high energy presentation
is augmented with photographs of historical, current, and future
space vehicles, their past and proposed space missions, and their
inventors. The presentation also includes the use of illustrative
scale models of rocket vehicles (such as the Space Shuttle) and
demonstrations of rocket construction (using small paper rockets
launched from soda straws and antacid powered rockets).
Available for grades 4 - 12.
"The Incredible Lever"
The workshop supports the Simple Machine,
history, and mathematics curriculum areas. It includes a discussion
and demonstration of the four forces that act upon an aircraft
and the concept of mass vs. weight. This is an interactive
workshop with the students constructing a paper airplane at the
conclusion. A motivational element that requires an addition
fifteen minutes can be added. Available for grades K - 12.
"Introduction to EngineSim, Introduction
to FoilSim, Topics in Aerodynamics and Propulsion"
The presentations demonstrate real world
applications of math and physics principles as applied to Aerodynamics
and Propulsion. They show participants why they "have to learn"
graphing, problem-solving using fractions or decimals, scientific
notation, trigonometry, rate problems, geometry, algebra, and
vectors. Newton's Laws of Motion, forces, moments, center of gravity,
and some basic thermodynamics principles of energy, work, and
power are also demonstrated. Presentations are geared to the specific
grade level of the requesting teacher. Introduction to EngineSim
demonstrates a computer program that is similar to FoilSim, but
one that simulates the operation of a jet engine. Introduction
to FoilSim, demonstrates an interactive computer program that
simulates the lift of a wing in a wind tunnel. Topics in
Aerodynamics and Propulsion is based on a Web site called "The
Beginner's Guide to Aeronautics." Topics include:
Aircraft parts and motion - four forces
on an aircraft - relative velocity

lift - curve
Drag and weight - factors that affect drag
- falling objects - terminal velocity
Thrust - jet engine types - jet engine parts
and operation
Propulsion systems - turbojets - rockets
- propellers
Gases - properties - equation of state -
atmospheric models
Optional - as required by the requester
Available for grades 5 - 12.
"Meet a NASA Employee Involved in Aerospace
Research"
What is it really like to work on a NASA
aerospace project? Who works on aerospace projects for NASA? What
is their background and how did they become qualified for their
jobs? These and other questions are answered during this presentation
for students. Selected NASA aeronautical engineers, scientists,
and project managers are available for this career exploration
session. Available for grades 7 - 12.
"Propulsion"
The concepts introduced in this presentation
are Newton's Third Law of Motion; creating and using graphs to
analyze information; basic rocket propulsion; and the aerodynamics
of propellers. This hands-on interactive session will step
teachers or students through a lab on the basic concepts of propulsion.
Newton's Third Law of Motion is presented as the governing physics
concept of all propulsion systems. Participants will use
balloons, string, and tape measures to conduct an experiment that
demonstrates rocket propulsion. The air in the balloon will represent
fuel for a rocket propulsion system, and the relationship between
volume of fuel and distance will be examined. Participants will
create a graph in order to depict this relationship. The aerodynamics
propeller will also be described, and a handheld propeller will
be used to demonstrate the concept of lift. Available for
grades 4 - 6.
"Tours of NASA Glenn Research Center Facilities"
The presentations explore research facilities
at the NASA Glenn Research Center, including the history of the
facility, how the facility works, the research conducted in the
facility, and why the research is important. Each presentation
consists of a 10-minute videotape about the facility followed
by a 20-minute, question-and-answer session with the facility
manager. A presentation can be requested for the following facilities:
The Icing Research Tunnel is Glenn'
oldest and busiest facility. Built at the end of World War II,
the IRT was instrumental in developing and testing ice protection
systems for piston- and propeller-driven aircraft. The IRT has
played a substantial role in developing, testing, and certifying
methods to prevent ice buildup on gas-turbine-powered aircraft.
Work continues today in the investigation of low-power electromechanical
deicing and anti-icing fluids for use on the ground, deicing and
anti-icing research on Short Take Off/Vertical Landing (STOVL)
rotor systems, and certification of ice protection systems for
military and commercial aircraft.
The 8- by 6-Foot Supersonic Wind Tunnel
(8x6), NASA's only transonic propulsion wind tunnel, reaches
test section speeds from Mach 0.36 to 2.0. The facility can operate
in either an aerodynamic cycle (for testing aerodynamic performance
of system components such as inlets, nozzles, and propellers)
or in a propulsion cycle (for testing live engines). No exhaust
scoop is required in the propulsion cycle.
The 9- by 15-Foot Low-Speed Wind Tunnel,
housed in the return leg of the 8- by 6-Foot Supersonic Wind Tunnel,
provides the nation with a unique facility for testing large-scale
hardware in a continuous subsonic airstream. The test section
is 9 feet high by 15 feet wide by 28 feet long, and airspeeds
from 0 to 175 mph can be provided. The facility is used to evaluate
aerodynamic performance and acoustic characteristics of nozzles,
inlets, and propellers, as well as to investigate hot gas reingestion
of short takeoff and vertical landing (STOVL) concepts.
Available for grades 5 - 12.
"Advanced Space Propulsion Concepts"
The presentation outlines the basic space
propulsion system requirements for concepts enabling human exploration
of the outer solar system. The rationale for quick trips between
planets is discussed, principal engine parameters are identified,
and prospective missions are proposed. Propulsion concepts are
primarily nuclear fusion based, though matter-antimatter annihilation
and similar concepts can be addressed. Available for grades
9 - 12.
"Exploring Mars: Parts 1 - 5"
The Exploring Mars series focuses on Mars
in human history, with special emphasis on recent missions, including
Mars Pathfinder. Each part may be requested as a stand-alone presentation,
or the parts may be requested as a series.
Exploring Mars Part 1: Beginnings
discusses ancient Roman calendar history, in which Mars played
an essential role; Schiaparelli and Lowell and their attempts
to map the Martian surface via telescopic observations in the
nineteenth century; and twentieth century Mars exploration by
cameras and robotic spacecraft. The Mariner, Viking, and Pathfinder
missions are introduced, including photographs of the spacecraft
and the Martian landscape as seen both from orbit and from the
surface. A discussion of the possibility of Martian life, including
photos of possible Martian fossils, concludes with information
on research to answer the question, "Was Mars at one time alive?"
Exploring Mars Part 2: The Planet
looks at Mars' tectonic history. Comparisons are made between
Mars and other planets and moons from the inner solar system,
including their relative sizes and colors. Mariner's Valley and
Tarsus Volcanoes are compared by size and terrestrial features.
The Martian climate and the most recent Mars Global Surveyor finding
on Martian planetary magnetism are discussed. The question of
life on Mars is also raised.
Exploring Mars Part 3: The Future
presents a three-step approach to sending humans to Mars, one
of several scenarios developed by NASA in the 1980s-90s. Step
1 is an Earth-orbiting space station, Step 2 is a return to the
Moon, and Step 3 is the first piloted mission from Earth to Mars.
The possibilities of colonization and living on Mars are discussed,
as well as how astronauts might deal with Martian life.
Exploring Mars Part 4: Pathfinder's
Path I is designed for mathematics students and future astronomers.
It begins with the observations of Tycho Brahe and the Laws of
Planetary Motion developed by Johannes Kepler. Through the use
of conic sections, a connection is made between the ellipse as
a classroom entity and the ellipse as a planetary orbit with specific
physical properties. Orbital terminology is introduced, and students
are challenged to work through the equation of an ellipse as a
follow-up activity.
Exploring Mars Part 5: Pathfinder's
Path II allows students to become very familiar with the Hohmann
transfer ellipse and with the basics of orbital calculations.
It introduces the Vis-Viva equation (conservation of energy) and
challenges students to work out some of the actual orbital parameters
required for the Pathfinder spacecraft to travel from Earth to
Mars. Available for grades 5 ? 12.
"Human Exploration and Development of Space"
This workshop allows participants to become
aware of the problems to be overcome in putting humans in space.
Participants learn about the history of spaceflight and the significance
of the Mercury, Gemini, and Apollo missions. Participants learn
what it is like to live in space--the joys, the hardships, and
the challenges--and about future missions. Participants are presented
with a variety of activities to illustrate various elements of
training humans for space. Available for grades K - 12.
"Apollo Moon Landings ? Fact, Not Fiction"
Since the airing of a program on national
television called "Conspiracy Theory: Did We Land on the Moon?"
many questions about the legitimacy of the Apollo Moon landings
between 1969 and 1972 have resurfaced. The Science@NASA Web site
responded immediately by posting an excellent Web page outlining
in detail the evidence that Apollo was exactly what NASA said
it was. One subject not raised at all in the program
was the more than 800 pounds of lunar rocks that astronauts brought
back to Earth. Geologists have been examining these samples for
30 years, and from them we have learned much about the formation
of the moon. An in-depth discussion of the analysis of Apollo
lunar samples is available from the Lunar and Planetary Institute
Web site. This videoconferencing session gives participants
an opportunity to discuss their questions about the landings on
the Moon with a panel of NASA researchers. Available for
grades 2 - 12.
"Humans to Mars"
The presentation is an overview of NASA's
1987-92 Space Exploration Initiative study, as well as current
plans to send humans to the planet Mars. The objectives of the
program, mission overview, Earth-Mars transit space propulsion
systems (nuclear thermal and nuclear electric), space environment
concerns, how people would live on the Martian surface, and initial
colonization plans are covered. Current status of the ongoing
robotic mission (Global Surveyor) and the role of the NASA Glenn
Research Center during this effort are explained. Brief videotape
footage is included. Available for grades 4 - 12.
"Mission to Planet Earth"
Taking care of our environment will take
on new meaning and relevance to participants as they participate
in the NASA Mission to Planet Earth (MTPE) activities. The workshop
allows participants to become aware of the factors that control
the quality of air we breathe and some of the aspects we have
come to understand as weather. Pictures of Earth taken from space
illustrate different types of weather, and participants are able
to relate this information to their everyday lives. Activities
and models explain concepts related to weather and atmospheric
pollution, as well as the process by which we transmit weather-related
images. Available for grades K - 12.
"Cassini Mission to Saturn"
The presentation is an overview of the Cassini
mission, an unmanned interplanetary probe of the planet Saturn,
which was launched in October 1997. The scientific objectives
of the mission, preparations for launch, and an overview of the
events that will take place when the spacecraft arrives at the
planet are covered. The roles of the NASA Glenn Research Center
and the presenter during the mission are discussed. Available
for grades 4 - 12.
"Comets"
Comets have fascinated people throughout
the ages. But only in recent times have we come to understand
and appreciate the significance of comets. This presentation focuses
on the history of thought about comets, the exploration of comets
with the advent of the space age, and current models for a comet.
Participants are shown how to make a model comet.
Current and future NASA missions to study
comets are discussed, and Internet resources are demonstrated.
Available for grades 6 - 12.
"Comets: Visitors from the Unknown!"
This interactive lesson focuses on what
happened to all of the debris that was left behind after the initial
formation of our solar system. Students are guided into discovering
that rocky debris fell onto the newly formed planets, causing
craters in solid surfaces, while icy debris was swept out of the
solar system by the solar wind. The icy debris orbits our sun
in an enormous cloud midway between our sun and the next closest
stars! These condensed clots of ice, stone, and dust (dirty snowballs)
are comets, according to the theoretical work of Jan Oort. We
see comets when they fall inward toward the sun.
Throughout time, the solar system seems
to have undergone periods of unusually heavy meteoric bombardment
followed by long periods of quiet. Fossil records show that periodic
mass extinctions occurred every several hundred million years
or so on earth. The meteoric material may have come from great
showers of comets that periodically made group excursions toward
the sun. The reason for this periodic behavior is an important
question in modern science. Students are challenged to arrive
at the conclusion that our sun may actually have a dark companion
star that passes into and out of the Oort Cloud, causing major
disruptions, and sending large numbers of comets falling toward
the sun.
Next, the students explore the appearance
of comets in our skies and identify various cometary features.
A comet is followed along its journey from deep space, around
the sun, and back out to deep space again, showing changes that
occur in its structure and appearance. The students are then challenged
to recognize the connection between periodic meteor showers and
the orbits of periodic comets.
Finally, the Age of Dinosaurs is revisited
at about 65 million years ago, when a massive object struck the
Yucatan Peninsula and caused the most recent mass extinction.
Louis and Walter Alvarez are introduced, and their ground-breaking
work with the Yucatan object is briefly discussed. (Students who
have seen or read "Jurassic Park" will be familiar with the KT
boundary.) Available for grades K - 12.
"Elements of Space"
Space is what most people perceive NASA
is all about. The exploration of space has been the stuff of dreams
for countless generations. This presentation addresses the elements
that make up space. It includes: the history of space exploration,
where space begins, what space is like in terms of microgravity,
weather in space, and fabulous views from space.
Participants will also be shown NASA Internet
resources that assist in the understanding of space. Available
for grades K - 12.
"Energy from the Sun"
This presentation focuses on the sun as
a source of energy. The solar constant is introduced, and the
audience is led through a series of calculations that demonstrate
the sun's energy output. The discussion includes:
harnessing the sun's energy, the solar cell as an energy transducer
, basics of solar cell science, materials used in manufacturing
solar cells, macroscopic characteristics such as efficiency, load
lines, a basic pictoral explanation of how to solve a simple circuit
with a nonlinear power-producing element the wide ranging
use of solar cells on Earth and in space. Mr. Kolecki has
worked with NASA for over 30 years, during which he has studied
Earth orbital space, the Moon, and the Martian surface. He was
a participating scientist in the recent Pathfinder mission. Currently,
he is a member of the Learning Technologies Project at NASA Glenn
where he hopes to reach out to audiences everywhere with a story
of hope for the future and a call to reflect back upon our own
basic humanity in an unprecedented time of technological growth.
Available for grades 9 - 12.
"Exploration of the Solar System"
The workshop covers the history of space
exploration with descriptions of the spacecraft and pictures of
the planets taken by the spacecraft. The pictures show the evolution
of our understanding of the Solar System. Available for
grades 4 - 12.
"Galileo Mission to Jupiter"
The presentation is an overview of the recently
completed Galileo mission, an unmanned interplanetary probe of
the planet Jupiter. The accomplishments of the mission, preparations
for launch, current spacecraft status, and an overview of the
extended mission at Jupiter are covered. The roles of the NASA
Glenn Research Center and the presenter during the mission are
discussed. Available for grades 4 - 12.
"Mars"
This workshop allows participants to become
aware of the conditions that exist on Mars. It also allows participants
to demonstrate/work with the scientific method in exobiology as
it pertains to Mars. Available for grades K - 12.
"The Moon"
The Moon videoconference provides participants
the chance to become aware of the outcomes of the Apollo program
and the processes that come into play to create the surface we
see when we view the Moon. Participants are presented with numerous
activities to explain geological processes that shaped the Moon’s
surface. Lunar materials are available for classroom use.
Available for grades 4 - 12.
"Scaling the Cosmos"
This presentation takes the audience on
an interactive voyage through cosmic space and time and seeks
to reveal the vast extent of the cosmos through scaling. The emphasis
is on numerical model building, how it can help our understanding,
and how it can reveal limitations in our ability to ever truly
grasp things on a cosmic scale. Four episodes are included:
the Earth-Moon system, the solar system the cosmos, geological
time. The audience is challenged to complete some of the
calculations and to suggest metrics for some of the models presented.
The author then discusses his own solutions. Mr. Kolecki
has worked with NASA for over 30 years, during which he has studied
Earth orbital space, the Moon, and the Martian surface. He was
a participating scientist in the recent Pathfinder mission. Currently,
he is a member of the Learning Technologies Project at NASA Glenn
where he hopes to reach out to audiences everywhere with a story
of hope for the future and a call to reflect back upon our own
basic humanity in an unprecedented time of technological growth.
Available for grades K - 12.

Space Science or they watch demonstrations on how to access NASA’s
Internet resources. Available for grades K - 12.
"Space and the Solar System"
The presentation on space and planetary
exploration begins with images from deep space taken via ground-based
telescopes and the Hubble Space Telescope. The audience is carried
on a voyage of discovery that focuses on our sun and its family
of planets as part of the Milky Way galaxy and ends with a photographic
tour of the solar system itself. Pictures from a variety
of NASA missions, ranging from the middle of the twentieth century
to the turn of the millennium, are used to show and explain the
dazzling panorama of worlds around the sun that await future discovery
and exploration by robotic and piloted missions. The human element
in space exploration is stressed with historical comments on Kepler,
Galileo, Newton, and Einstein. NASA's role in and the future of
space exploration are discussed. Audience participation
is invited throughout. Mr. Kolecki has worked with NASA
for over 30 years, during which he has studied Earth orbital space,

that transmits a video picture to any TV. This robot has a pair
of electric squirt guns, which are demonstrated. The autonomous
robot uses infrared light to detect and avoid obstacles while
walking. There is also a small robot that the audience can move
by clapping their hands. The presentation may include a short
video on robot competitions. Available for grades K - 12.
"Fermi’s Piano Tuner ? Making Estimates
in Physics"
ometimes in our work at NASA, we must attempt
to estimate important scientific and/or engineering values based
on scanty information. Experimental science seeks its answers
from Nature. But before an experiment can be designed, some idea/estimate
of the parameter space must be known. Often we must make an initial
guess. How should we proceed? Enrico Fermi, the Italian
physicist of Manhattan Project fame, knew only too well that physicists
are often confronted by situations in which they are forced to
reason from minimal information. He, therefore, taught his students
how to think in such a world by using a strange type of problem,
one designed to demonstrate how everyday knowledge can be used
to answer surprisingly difficult questions. As a lecturer,
Enrico Fermi challenged his physics classes with problems that,
at first glance, seemed impossible. Fermi's Piano Tuner
is an example of this type of mathematical problem: "If
3,000,000 people live in Chicago, then how many of them are piano
tuners?" When the class returned a blank stare, Fermi
would proceed in a methodical way to show how we can draw information
from everyday life to make up for what we lack in real data.
Mr. Kolecki has worked with NASA for over 30 years, during which
he has studied Earth orbital space, the moon, and the Martian
surface. He was a participating scientist in the recent Pathfinder
mission. Currently, he is a member of the Learning Technologies
Project at NASA Glenn, where he hopes to reach out to audiences
everywhere with a story of hope for the future and a call to reflect
back upon our own basic humanity in an unprecedented time of technological
growth. Available for grades 9 - 12.
"Have you Looked at Your Calendar Lately?"
Have you ever taken a careful look at your
pocket calendar? You might be amazed at just how much history,
mythology, mathematics, and astronomy you would find there! For
example: the day names derive from Norse and Teutonic sources.
The month names derive from Ancient Rome! Mars plays a significant
and somewhat surprising role in calendar etymology. Astronomically,
the calendar was long in coming in the Western world. Acquiring
an accurate measure for the length of the tropical year by observation
was no mean task and involved at least two major reforms over
the millennia. From Ancient Rome, through Julius Caesar
and Pope Gregory, and into modern time, Mr. Kolecki sketches the
story of the calendar in an easy to understand semi-cartoon format.
He then returns to antiquity, and traces out the necessary numerical
calculations to enable the student to grasp the subtleties and
to appreciate the marvel, which is the calendar, so easily taken
for granted in these times of high tech devices and inventions.
With Y2K in the news, the problem of time keeping is at the front
of many people's thoughts, making this presentation especially
timely for classrooms or adult groups. Mr. Kolecki first
wrote the mathematical section as a set of personal notes many
years ago, after a "casual" dialogue with his esteemed late colleague,
Dr. Ira Myers, who, in his customary manner, simply spun the calculations
off the top of his head. Because of the influence that Dr. Myers
had on Mr. Kolecki over the years, he has chosen, respectfully,
to dedicate this small piece to his memory. Mr. Kolecki
has worked with NASA for over 30 years, during which he has studied
Earth orbital space, the moon, and the Martian surface. He was
a participating scientist in the recent Pathfinder mission. Currently,
he is a member of the Learning Technologies Project at NASA Glenn,
where he hopes to reach out to audiences everywhere with a story
of hope for the future and a call to reflect back upon our own
basic humanity in an unprecedented time of technological growth.
Available for grades 9 - 12.
"Mathematics: Science of Numbers"
At NASA we are required to solve theoretical
problems and to interpret the results. The solving of problems
involves TECHNIQUE. The INTERPRETATION of results involves CONCEPT,
a type of understanding similar to that required for interpreting
a language. This lesson focuses on concept and interpretation.
It begins with comments on the nature of mathematics and the reasons
why interpreting results is important in research and science.
Practice in interpretation of results includes understanding the
concept of the magnitude of light speed. Mathematics is
presented as a science of numbers, a body of knowledge that represents
1) what we know about numbers and the operations between them;
2) the various properties of numbers; 3) the inherent means for
adding new knowledge; and 4) a system of concepts that allows
for interpretation. We learn TECHNIQUE in school. Technique
is the "know-how" for writing and solving equations. Concept and
interpretation are also taught, but take much longer to develop
in a person's mind. Concept is necessary for interpretation, and
interpretation is necessary for putting mathematics to the best
possible use. When we use mathematics in research and design,
interpreting our results is vital. Solving an equation but not
being able to interpret the result is like writing a grammatically
correct statement without knowing what you mean! Available
for grades 9 - 12.
Tours of the facility are also available.
