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
   Learn about observing procedure
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.
  1. 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.
  2. 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.
  3. Newton's Laws and Toys. Your group will make a video demonstration of Newton's Laws of motion.
  4. Optics: Lasers, Mirrors, and Jello. You will learn about how light reflects from mirrors and refracts in Jello and air.
  5. 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):
Monday
   1pm-3pm
Thursday
   12:30pm-1:30pm
Friday
   10am-noon
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.
