Syllabus
1. Course Description
AST 101L is a laboratory course meant for non-science majors who either are
taking or have taken AST 301. In it you will work in groups to learn more
about some of the experimental and observational topics you have heard and
read about in AST 301.
The class will be divided into groups of 4-5 students. Each group will work
together to carry out three 3-week projects. The groups are selected based on
which nights you have free to do the observing and on which three segments
you want to do most. If you are in the class with 3 or 4 friends, you can choose
to form a group. If you do not make up a whole 4 or 5 on your own, however,
we may choose to split you up.
2. Schedule
There is one scheduled class hour each week of the semester. In addition, the
groups will also have to meet at other times to work on the projects. In some
cases, you will need to gain access to restricted equipment; the TA will be
available during certain periods to allow this. At the end of each three week
period, your group will meet with the TA and/or the Prof. to discuss and
evaluate the completed project.
The observational projects will work a bit differently than the others. For
one thing, you will be expected to devote some evening hours to the projects.
Because these projects are so dependent on the weather, they will be scheduled
independently of the 3-week blocks. If your group chooses an observing project
for one of its three, you will need to come to class at one additional time during
the first 3 weeks of the semester to do the prep work. After that, you will need
to carry out your observations on the first clear nights for which your group has
a slot available.
WARNING: It has often turned out in the past that there were entire
three-week stretches without a clear weeknight. You MUST "make hay while
the moon shines" and get your observing done when you can. The upside of
this is that you may be done with this course early. If observing will occur on
a given night, the TA will email the class, so be sure to check your email
each afternoon.
For this course, the semester will be divided into three 3-class periods during
which you will work on projects:
T 9/5, W 8/30
|
|
Introduction, questionnaire
|
T 9/12, W 9/6
|
|

Introduction to Starry Night
|
T 9/19, W 9/13
|
|
Set up groups, choose labs
First 3-class period begins
|
T 10/10, W 10/4
|
|
All materials from first period due
Second 3-class period begins
|
T 10/31, W 10/25
|
|
All materials from second period due
Third 3-class period begins
|
T 11/21, W 11/15
|
|
All materials from third period due
Last possible observing night
Last day to hand in any make-up work
|
3. Grading
A grade will be assigned for your performance on each topic. It will be based on
material you will hand in, a group presentation or report, and your demonstration
of what your group has done in a meeting with the TA at the end of each
3-class period. You will work together to learn the material from each topic
and produce a report or presentation, but each of you must understand what
is in the report and what was done in your experiments. Members of a single
group will not necessarily all receive the same grade based on the discretion of
the professor and TA.
Individually, for each completed segment, the student will be assigned a
letter grade based on the materials and presentations.
A
|
|
Complete, Superior performance on most aspects
|
B
|
|
Adequate performance on all aspects
|
F
|
|
Incomplete, or complete but inadequate performance on all aspects
|
Ninety percent of the student's final grade will be calculated from the average
of three segment grades. The remaining 10% will be for participation credit.
Students missing more than 2 class sessions (after the 2nd week of classes) will
receive zero participation credit. Absences may also affect the student's segment
grades.
With an excused absence, students can make up two classes by arranging
with the TA to attend at one of the alternate times. Students doing the unaided
eye observing must obtain one "night participation credit" and students doing
the telescope observing two such credits from the TA. Failure to participate at
the required level will lower your final grade by one full letter. Be aware also
that actual active participation in your group's activities counts as part of your
performance on the segments.
4. Topics
There are currently five discovery kits, of which each group will choose three.
- Unaided Eye Astronomy. You will learn about what astronomers studied
before the invention of the telescope - positions of stars, motions of the
Sun and stars, and measurements you can make with simple instruments.
- Observing with Telescopes and Digital Cameras. You will learn to use
computer-controlled telescopes and CCD cameras to take wide-angle photographs
of the sky.
- Newton's Laws and Toys. Your group will make a video demonstration of
Newton's Laws of motion.
- Optics: Lasers, Mirrors, and Jello. You will learn about how light reflects
from mirrors and refracts in Jello and air.
- Optics: Lenses, Cameras, and Telescopes. You will learn about how lenses
work and how astronomical instruments can be made from them.
5. Office Hours
The TA will be available during the following times (office: RLM 16.212):

Additional hours will be announced on our web page once we know which hours
will serve the most people. During these times, you can gain access to the
equipment or ask questions of the TA. If you are unavailable during these times,
please contact the TA for other times. Also, you will be expected to attend
during the normally scheduled class time unless otherwise instructed.
