CARA Outreach / Yerkes Summer Institutes / Schedule from 1993
This document assumes you have read the general
information on the YSIs.
Theme is the Galaxy. Goal is to perform an interlocking set of
activities that build upon the experiences in the five on-campus labs and
the three nights at the Adler Planetarium. Besides simply experiencing
well-guided, hands-on astrophysics activities, by the end of the week the
students should be able to :
We continue to expect three student teams: Sgr, Sco & Cyg. The
numbers, though still a little uncertain, will be no more than ten on each
team. Each team will have two leadership students who will assist with
the lab in a mentoring role. On Sunday afternoon, starting at 1:00 PM, each
instructor will get 15 minutes to describe their activities before these
leaders. Be sure to give them written materials at that time so they can
help you in your activities.
- describe and discuss the Galaxy,
- describe the distance scales and how they were measured,
- read and interpret a star chart,
- use a small telescope,
- describe the relevant properties of light and optics in the above,
such as: inverse square law, simple optics, scattering and
absorption, plus how a camera works,
- explain what a meteor shower is and how comets and meteors are
thought to be related to the interstellar medium.
Dates: Sunday, August 8th through Saturday, August 14th.
Don't forget that all your activities must have their written
descriptions in Macintosh readable form. After this year's institute they
will be assembled in a binder for future year's reference and use.
Workshop Titles and Teaching Teams
The [...] leader of each activity or workshop [is listed].
You will have the assistance of the leadership students who are in
each team. Note that your plan must include a rain/cloud activity.
You are also responsible for turning in a Macintosh Word version
of the activity at the end of the Institute.
- Star Charts and Atlases
- Instructor: Brass, Kron
Use various atlases, including the Barnard atlas. Concepts to
be taught are angular measurements from linear distance on map.
- Globular Clusters - Star Counting
- Instructor: Takamiya
Using various photographic enlargements, determine the
numbers of stars in globulars and also some open clusters.
- Scattering, polarization and absorption of light
- Instructor: Newberg
Learn the basics of the physics of interstellar dust in the lab.
Then, make some observations of Palomar Sky Survey prints.
- Camera Obscura
- Instructor: Sweitzer, Dreiser
Experiment with a room-sized camera obscura. Take some
photos of the Sun with a smaller one and compare
brightness with Milky Way images. Estimate density of MW.
- Galactic Stories
- Instructor: Greer
Examine various myths and legends about the Milky Way.
Learn basic, qualitative model of the Galaxy. Then, exercise
writing and story telling skills by making up stories and
writing a description of the Galaxy.
- Proper Motions
- Instructor: Smetanka
Compare old photos with new ones to determine the velocity
of some stars. Distances too?
- Comets and Meteors
- Instructor: Whitt, Brown
Make a comet. Build conceptual bridge to interstellar dust and help
students get ready for upcoming meteor shower.
Actual labs from this might be found on our
- Gauging the Galaxy - Observing
- Instructor: Brass, Whitt, Greer, Brown
Using the Milwaukee small telescopes, determine the
relative stellar densities in 4 or 5 selected fields. Compare with
Herschel and make some conclusions.
- Globular Clusters - Observing
- Instructor: Smetanka, Takamiya
Using the 24 inch telescope, verify the distribution of
globular clusters. Learn about RA and Dec in the process. If
possible, discuss why globulars hover about center of MW.
- Photometry of stars and globulars - Observing
- Instructor: Sweitzer, Briggs
Using CCD mounted on various lenses on Schmidt, do
photometry of reference source, double stars and
globular clusters. Use data to determine the size of the Galaxy.
- Photograph Milky Way - Observing
- Instructor: Kron, Newberg
Wide-field photography of Milky Way. Small field
photography of high proper-motion star. Relate to
obscuration of dust. Also relate to photos of the Sun taken in daytime.
