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.
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. Observing nights will be announced on our
class website
(see the notes under Observing on this webpage). You need to check this URL every afternoon
until your observing project is completed.
Grading
A grade will be assigned for your perfomance 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 must attend at least 8 classes from the 2nd week
through the end.
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.
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 of demonstrations of Newton's Laws of motion
using toys.
- Optics: Lasers, Mirrors, and Jello. You will learn about how light reflects from mirrors and refracts in Jello.
Can you make your own lenses?
- Optics: Lenses, Cameras, and Telescopes. You will learn about how lenses work and how astronomical
instruments can be made from them.
Office Hours
The Professor or TA will be available during the following times (in the classroom, 13.132):
TBA
Additional hours will be announced on our webpage 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.
