PROGRAM: "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 
Model rockets - aerodynamic forces - stability - flight trajectory 
Lift - theories of lift - factors that affect 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"

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.
