LUNCH AND SPEAKER: 12:15- 2:00 PM

Folks, the real excitement this year is the fact that in addition to 25 papers, we have three workshops, one presented by the speaker, Dave Wall.  Dave is not just an accomplished teacher of physics; he’s a wonderful magician who incorporates his prestidigitory skills into his teaching.  I think we all agree that students need to learn to observe well, and there is no better way to pique their interest in observation than by “magic.”  Dave’s workshop will be devoted to teaching rope tricks.  This workshop is limited to 30 participants, and needs to be preregistered for so that the appropriate materials can be purchased for each participant.

On the next page is a short description of each workshop.  Please seriously consider attending as many activities as you can because we all agree that not only is physics phun, so are physicists.

WORKSHOP 1- STUDIO STYLE TEACHING AT ROSE-HULMAN

LEADER: SUDIPA MITRA-KIRTLEY

This workshop will focus on the rigors of special “Studio” classes conducted for introductory physics courses at Rose-Hulman Institute of Technology. The principle behind this mode is that the teachers spend very little time at the blackboard, and the students try out the physics concepts just learned, with several hands-on “mini-experiments”. There are no major three-hour laboratory sessions, as these labs are broken into smaller parts, and formatted into series of mini-experiments. The hands-on part may involve an actual experiment, or a simulation on the computer. The main advantage is that the lectures and the experiments are in sync with each other, and the students readily see the nature of the problems and how they could apply to the real world. This process ensures that the students come up with the right questions, and the concepts are more easily comprehended. It also allows the teachers to oversee each student’s performance, and therefore, be aware of the difficulties that each student may be having with the material. The students usually work in groups of two, and this is helpful in team-building skills as well as in building confidence in the students. The students still turn in several formal laboratory reports during the quarter, each based on data collected from one or several mini-experiments.

The two-hour workshop will feature a typical studio class in Mechanics. Several concepts in introductory mechanics will be talked about very briefly, and each time, the participants will perform some kind of a hands-on activity immediately after. Participants are encouraged to bring their laptops; if not, laptops will be provided if notified at the time of registration.

WORKSHOP 2- SIMPLE INSTRUMENTATION for SOUND LAB. EXPERIMENTS.

LEADER: UWE HANSEN, INDIANA STATE U.

One of the fundamental acoustics concepts deals with resonance. Resonance vibrations in a transverse string are easily demonstrated with the aid of a piece of surgical tubing filled with lead shot. The connection to music is readily made with a monochord. Air column resonance can be shown with varying the tube length by changing the water level in the tube, and exciting the air column with a tuning fork. An alternative method drives the air column with a swept sine signal using a piezo disk and monitoring the sound pressure with a microphone in a simple impedance head. Such a simple impedance head will be illustrated in the workshop. Instrumentation requirements include a computer with a sound card. The software needed along with parts to construct the impedance head will be provided for 10 workshop participants. This project is funded with support from the Acoustical Society of America.

WORKSHOP 3- PHYSICS AND MAGIC WITH A ROPE

LEADER: DAVE WALL

The workshop will focus on the use of rope tricks as a way of getting students to be careful observers and to appreciate the often times “non-commonsensical” nature of physics.  Participants will learn to do several tricks and get suggestions about how to incorporate them into the classroom.  Participants will also learn to appreciate the need for special tools of the trades such as rope and scissors.  In fact, each participant will receive special magic rope and a special pair of scissors.

ABSTRACTS

SESSION ALPHA

8:15: Two-stage relativistic rocket science

Dr. Joe West, Rose-Hulman Institute of Technology

We consider the optimal choice of the ratio of masses of the stages of a two-stage rocket that is to attain relativistic velocities.  The rocket is restricted to constant acceleration as experienced by the crew.  This builds on previous work on uniformly accelerated frames and relativistic rocket ships of single stage design by others.  We wish to estimate the benefit of the two-stage design for a representative trip from Earth to Vega, using realistic mass ratios in an anti-matter powered ship.  In particular, we wish to compare the travel time as observed by Earth, crew and Newtonian observers for both single-stage and optimized two-stage relativistic rockets.  It will also be noted that Earth based observers will predict an increase in the efficiency of the anti-matter drive as relativistic effects become noticeable

8:30:Simple method for measuring the focal length of a zone plate using diffraction

R. M. Bunch, Rose-Hulman Institute of Technology

A zone plate is a screen that changes the amplitude or phase of an incident wavefront for all

of the even or odd half-period Fresnel zones.  Zone plates are often thought of as only being an

artifact of Fresnel diffraction.  However, there has been increased interest in the use of zone

plates as optical elements in systems because they are compact, lightweight and can be

easily fabricated.  A simple method for determining the focal length of a zone plate will be

described during this talk.  In this method, a zone plate is scanned through an incident laser

beam sampling a small section of the zone plate.  When the beam encounters a locally-periodic

amplitude and/or phase obstacle on the zone plate it is diffracted.  The resulting diffraction

pattern observed from a sampled section is used to compute the focal length of the zone plate.

This method provides an interesting lab experiment for undergraduate students learning about

diffraction.

The minimum time of transit, and the accompanying radius of the path  taken by a particle constrained to traverse the circular arc starting  from rest at one point (xo, yo) to some lower point (xf, yf) when under the influence of the constant gravitational field of the Earth are determined numerically.  For three example cases the path followed for the minimum time is compared with the cycloids obtained from the unconstrained version of this problem, the brachistochrone.  Other examples utilize the versatility offered by a numerical solution to estimate the optimal value of the radius and transit time, when the effects of wind resistance are included

9:00: Issues and Ideas in Teaching Magnetism*

David Maloney,Indiana U-Purdue U. Fort Wayne

This talk will describe some of the conceptual difficulties students have with the topic of magnetism and present some materials designed to enable instructors to get students actively involved in reasoning about the concepts and principles.

*Supported in part by CCLI grants from the National Science Foundation.

9:15: Experimental and Analytical Skill Building in the Introductory Laboratory*

David Maloney, Indiana U-Purdue U. Fort Wayne

This talk will describe our efforts to shift the focus of the introductory general physics laboratory from demonstrating phenomena to developing skills necessary to conduct scientific investigations.

*Supported in part by CCLI grants from the National Science Foundation

9:30: PHYSICS  DEMONSTRATIONS  NIGHT

Charles Emmert, Hugh Ross, Layne Maki, Noblesville High School

Physics teachers at Noblesville HS, assisted by some physics students, perform a variety of physics demonstrations in an evening program.   This is used as a way of reaching and exciting younger students about their study of science and future study of physics concepts.   The 11th Annual Physics Demonstrations Night was March 27.

9:45: A PHYSICS OLYMPICS FOR YOUR HIGH SCHOOL CLASSES

Charles Emmert, Hugh Ross, Layne Maki,Noblesville High School,

Physics students at Noblesville High School are preparing for the 13th Annual NHS Physics Olympics, May 14, 2001.   Teams of 6-7 students are organized to participate in a series of events in which the students use teamwork to apply physics concepts to a variety of situations.   Descriptions and handouts of some of the events, schedule, volunteer form, etc., along with some video clips of past Physics Olympics will be provided

SESSION BETA

8:15: Multimedia Physics Laboratory Simulations

Richard W. Tarara, Saint Mary's College

Armed with a Technology Grant from Ameritech I have begun a project to address certain pedagogical problems with current physics laboratories at the high school and college level.  By using digital video sequences and animated computer simulations this work will provide a training tool which can be used by students to prepare for their laboratory experiences, to help

analyze their labs, and to further explore the physical  concepts involved in the lab exercises.  The package will allow students to 'make-up' missed labs in a virtual experiment and can be used (where appropriate) to provide a virtual lab experience when the necessary laboratory equipment is not available to a particular school.  The multimedia package will be distributed free over the Internet.  At this meeting I will show the progress to date.

8:30: Data Analysis of FNAL E781 Data at the BSU HEP Laboratory

Dr. Luiz G. Emediato (Ball State U. visiting scholar)

Dr. Gerald P. Thomas (Ball State U.  speaker)

The updating of the BSU HEP lab's 3 PC's and 2 Workstations hardware and software, as well as their networking scheme will be described as well as their use in analyzing FNAL E781 charm data with reference to the detector alignment and mass reconstruction.

• Special Thanks to an NSF RUI grant (PHY-99-79204) for support toward this project

8:45: Seismology in High School Physics - The Princeton Earth Physics Project

Jeff Sayers,Northview High School, Brazil, IN

Physics students at Northview High School have the opportunity to see how physics enters into the real world phenomenon of earthquakes.  Northview Students assist in the operation of a research quality seismic station, collecting data from earthquakes that occur all over the world.  Northview is a participant in the Princeton Earth Physics Project(PEPP), a national education and research project involving around 70 schools across the country.  This presentation will describe how Northview works with Princeton and Indiana Universities to give students a first hand introduction to seismic research and real-world applications of physics.  Information on how interested schools can become participants in the project will also be available.

9:00: QuarkNet: Viewing Cosmic Rays

Beth A. Beiersdorf, LaSalle HS, South Bend, IN

Robert LeBlanc, University of Notre Dame

The University of Notre Dame participates as a Center in QuarkNet, a national NSF program to partner high school physics teachers with particle physicists working in science at the energy frontier on experiments in hadron collider physics.  Our ultimate aim is to reach and attract high school students to the excitement of basic research in the physical sciences.  Our center offers students the opportunity to participate in construction of detectors for colliding beam experiments at Fermilab, Batavia, IL and at CERN, Geneva, Switzerland.

One of the results of investigations has led to the creation of a cosmic ray (muon) detector.  This device includes a screen for a person to actually view cosmic rays as they pass through the device showing the direction from which it came.  Recently, the Smithsonian Institution’s Air and Space Museum has requested a cosmic ray detector from Notre Dame’s QuarkNet Center to be put on permanent display.  Work is now being done to meet that request.

9:15: QuarkNet and Science Alive!

Robert LeBlanc, University of Notre Dame

The University of Notre Dame participates as a Center in QuarkNet, a national NSF program to partner high school physics teachers with particle physicists working in science at the energy frontier on experiments in hadron collider physics.  Our ultimate aim is to reach and attract high school students to the excitement of basic research in the physical sciences.  Our center offers students the opportunity to participate in construction of detectors for colliding beam experiments at Fermilab, Batavia, IL and at CERN, Geneva, Switzerland.

One of the projects of the Notre Dame QuarkNet Center is involvement in an interactive display at the local library’s annual Science Alive! day geared to children in grades K-8.  Many exhibits were shown by QuarkNet this year including optical fibers, muon detection, diffraction, polarization, and electron tracks.

This display has been set up and run by university physicists in the past.  It has since been passed on to high school physics teachers, university physics students, and high school students.  This year’s display was run by 1 University of Notre Dame professor, 8 high school physics teachers, 1 undergraduate physics student and 7 high school students.

9:30: QuarkNet:  Exploring the Frontiers of High Energy Physics

Beth A. Beiersdorf, LaSalle High School, South Bend, IN

The University of Notre Dame participates as a Center in QuarkNet, a national NSF program to partner high school physics teachers with particle physicists working in science at the energy frontier on experiments in hadron collider physics.  Our ultimate aim is to reach and attract high school students to the excitement of basic research in the physical sciences.  Our center offers students the opportunity to participate in construction of detectors for colliding beam experiments at Fermilab, Batavia, IL and at CERN, Geneva, Switzerland.

The Dzero Experiment at Fermilab has recently begun Run II after a five-year break for upgrades.  The goal of the experiment is to study the head-on collisions of beams of protons and antiprotons at a center-of-mass energy of 2 TeV.  Goals of the experiment also include study of the top quark and searches for a variety of new phenomena including Higgs bosons, supersymmetry, and evidence of extra dimensions.  Key to these studies are the measurement of particle momenta and the ability to trigger on particles of high transverse momentum.  The newly-built central tracking system – with the Central Fiber Tracker - accomplishes this.  At the Notre Dame QuarkNet Center, teachers and high school students were involved in research and the construction of several hundred fiber-optic waveguide bundles used to transmit scintillation signals to photosensors for over 75,000 channels.

The CMS Experiment at CERN is being built to study the head-on collisions of beams of protons at a center-of-mass energy of 14 TeV.  This experiment is scheduled to begin operation in 2005.  Goals of the experiment include searches for a variety of new phenomena including Higgs bosons, supersymmetry and evidence for extra dimensions.  Key to these studies are the measurement of particle energies and missing energy.

SESSION GAMMA

10:00: Zope!, Zwiff! Flash!, Novel use of technology in Teaching and Assessment... is it hype or real?

Steve Spicklemire, University of Indianapolis

Technology is fun, but is it useful? This presentation describes the beginnings of a somewhat systematic effort to use various technologies in teaching with the idea of building a volume of data that could be used to assess effectiveness. The key technologies are: Zope (Z Object Publishing Environment, used to distribute teaching and assessment tools via the Internet), Flash (multimedia authoring to permit fairly easy development of demo/simulation ware), and Director, to provide a robust, yet easily distributed base platform that can also work in a web browser.

10:15: Complexity Insights in Humanities

Michael McInerney and Michael Aycock, Rose-Hulman Institute of Technology

Complexity is the study of interacting agents and their emergent behaviour.  It is couched in the language of dynamics with phase space, attractors, repellors and so forth.  One of the uses of Complexity is to use this language to gain insight into intractable problems and questions such as 'Is this painting good?' and 'Which of these two poems is the best?'.  In this paper we will attempt to couch these questions and others in the language of complexity and thus gain a new view on them.  Solutions should not be expected.

10:30: Atomic Orbitals without Scrodinger's Equation

Michael McInerney, Rose-Hulman Institute of Technology

In my experience, the teaching of atomic theory proceeds smoothly up to the introduction of Schrodinger's Equation.  The equation itself is easy to understand; it is the solutions that appear magical and without a commonsense basis.  In this paper I attempt to show that the shape of the electronic orbitals around the nucleus can be explained and understood without recourse to Schrodinger's equation but based on the fundamental quantum premises of indistinguishability and fermi exclusion.  A detailed analytical description is, of course, best approached through Schrodinger's equation.

10:45: Collisions in Two Dimensions:  Students Make and Analyze Videos.

Mike McFarland, Notre Dame University

Students learn about conservation of momentum by first making videos of air-table collisions, and then analyzing the videos.  Such an experiment is the subject of this talk.  The talk covers three topics:  the equipment, the experiment itself, and the                 problems encountered.  This talk is appropriate for faculty interested in experiments for the introductory laboratory.

11:00: Strong Correlation Between Exam and Web-Based Homework Performance in Introductory Physics

Jerry D. Hinnefeld, Indiana University South Bend.

The web-based homework tool CAPA¹ has been used during the last four semesters in a calculus-based introductory physics sequence.  Student performance on CAPA homework sets is strongly correlated with performance on corresponding unit exams.  A similar analysis of data from several earlier semesters, in courses utilizing hand-graded homework, shows at best only a weak correlation between exam and homework scores.  The correlation between CAPA and exam scores does not necessarily imply a causative relationship, and alternative interpretations will also be presented.

¹E. Kashy et al., Amer. J. Phys. 61, 1124 (1993).

11:15: Use of the Internet to Enhance Physics Education

Shirvel Stanislaus, Valparaiso University

With the advent of the internet, teaching techniques have started to undergo some significant changes. During the last 3 years, we, at Valparaiso University have carried out a pilot project to use the internet as a supplement to enhance the teaching of introductory level calculus-based physics. The results of this project are very encouraging. In this talk I will outline some of the traditional pedagogical challenges associated with teaching introductory physics and then describe how we were able to use the internet to help overcome some of these.  I will include longitudinal, normalized performance data to illustrate these successes.  At the end of the talk, the participants will be encouraged to share their stories of successes and failures associated with using the internet in teaching.

SESSION DELTA

10:00: In-class Activity for Reinforcing Newton's Laws and Centripetal Force

Dave Vesper, Indiana State University

The concept of Centripetal Forces can be valuable for reinforcing Newton's Laws of Motion in introductory general physics. It is also a source of student confusion as students have trouble reconciling a 'center-seeking' force with a force that they know pushes them to the outside of a circle in a turning car. I present a short worksheet and in-class exercise to reinforce centripetal force. Students model a car and driver with small wooden blocks. By first examining and discussing the net force on the driver when the car accelerates forward, and then examining a turning car, students should get a better understanding of Newton's Laws of Motion.

10:15: A study of anti-vibration tables used in simple holography Experiments

Matt Akers* and John Swez, Indiana State University

Even simple transmission and reflection holography experiments require practically

vibration free tables since movement during the exposure of film in the holographic process can be totally disruptive.  The results can be poorly made holograms.  Vibration free tables are commercially available but very expensive and beyond the holographic budget of most schools.  We have constructed a simple horizontal pendulum harmonic

oscillator driven by external vibrations present, such as those on a holography table. The electrical signals resulting are analyzed by FFT analysis using a simple digital oscilloscope interfaced to a lap top computer.  We have constructed holography tables made from sorbothane vibration mounts (available from Edmund Scientific) and have had good success with holography.

10:30: Measuring the speed of Sound in Air with an Acoustical Interferometer and an Investigation of the Conservation of Sound Energy.

Darrell Megli,University of Evansville

Sound waves from a small loudspeaker are divided, with one portion passing through a fixed length of plastic tubing and the other portion passing through a slide from a slide trombone.  The two waves are combined at a tee connection containing a small microphone used to detect conditions of constructive and destructive interference.  By moving the slide, a series of maxima and minima in the pressure amplitude can be found for determining the wavelength of the sound.  Knowing the frequency, the speed of sound can be calculated.

10:45: Investigating the Strike Tone Frequency of an Orchestral Chime.

Darrell Megli, University of Evansville

A hollow cylindrical steel pipe (simulating an orchestral chime) is suspended and struck with a wooden mallet.  The musical pitch is matched with a musical tone produced by a function generator.  The frequency of the generator is the strike tone frequency.  The waveform of the sound from the chime is recorded and Fourier analyzed to determine the fundamental and overtone frequencies.  The predicted transverse vibrational frequencies are also compared with the measured frequencies.  The relationship between the measured frequencies and the strike tone frequency is discussed.

11:00: Report on a "Textbook-less"  Electronics Class

Paul R. Errington, Ball State University

The Department of Physics and Astronomy at Ball State offers a two-semester course in introductory electronics.  The first semester is primarily analog electronics and the second semester is primarily digital electronics.  In past years, the instructor has used various textbooks including "The Art of Electronics" by Horiwitz and Hill, and "Electronic Instrumentation for Scientists and Engineers" by Diefenderfer.  This year in lieu of a textbook, students were required to purchase the software package Multisim (Electronics Workbench) for use on their own computers.  This paper reports on the instructor's evaluation and student's sentiments on a course with computer software but no textbook.

11:15: Dose Optimization for High Dose Rate Applications in Brachytherapy

Ana Mihail, Joe Butts*, Al Foster*, and David Ober, Ball State U.

Ball Memorial Hospital uses the Microselectron-High-Dose Remote Afterloading System developed by Nucletron to deliver precise dosages of radiation. Radiation is automatically delivered through an applicator which is positioned

within the body.  In this procedure a higher dose of radiation is applied directly to the tumor while sparing healthy tissue and surrounding organs.  The current study was undertaken to study the optimal number and the location of radiation source positions which will provide a uniform radiation dose profile along a cylindrical applicator.  Simulations were performed to provide radiation dose profiles for point sources; the superposition of selected point sources was then used to predict optimal geometries for source locations selected as inputs to Nucletron dose optimization software.  Sample results will be presented.
