  1. Objectives (AKA Purpose)

  2. The main objective is ...

    We touch on the following topics:

    1. Hm.


  3. Preparation

  4. Do the preparation required by your lab instructor.

    1. Prep Items:

      1. Read this lab exercise itself: Lab X: .

        Some of the Tasks can be completed ahead of the lab period. Doing some of them ahead of lab period would be helpful.

      2. It is probably best to print out a copy of Report Form on the lab room printer when you get to the lab room since updates to the report forms are ongoing.

        However, you can print a copy ahead of time if you like especially if want to do some parts ahead of time. You might have to compensate for updates in this case.

        The Lab Exercise itself is NOT printed in the lab ever. That would be killing forests and the Lab Exercise is designed to be an active web document.

      3. Do the prep for quiz (if there is one) suggested by your instructor.

        General remarks about quiz prep are given at Quiz Preparation.

        For DavidJ's lab sections, the quiz prep is doing all the items listed here and self-testing with the Prep Quiz and Prep Quiz Key if they exist.

      4. This is an observing lab. So you should review Telescope Operation and List of Tricks for the Telescope as needed.

        Review the parts of the Celestron C8 telescope in the figure below.

        You should also review the Observation Safety Rules.


      5. There are are many keywords that you need to know for this lab. Many of these you will learn sufficiently well by reading over the Lab Exercise itself.

        However to complement and/or supplement the reading, you should at least read the intro of a sample of the articles linked to the following keywords etc. so that you can define and/or understand some keywords etc. at the level of our class.

        Keywords:

        A further list of keywords which you are NOT required to look at---but it would be useful to do so---is:

          Hm.

    2. Prep Items for Instructors:

      1. From the General Instructor Prep, review as needed:
        1. Basic Prep.
        2. Usual Startup Procedure.
        3. Usual Shutdown Procedure.

      2. Since this is an observing lab, you should check the NWS weather well in advance of the lab night.

        Patchy cloud cover may be OK for this lab exercise. You will have to make a judgment call based on visual inspection of the sky.

        If the sky is going to be heavily clouded, then an alternative lab exercise without observations (or for which observations are NOT essential) from the Introductory Astronomy Laboratory Exercises.

      3. We never do observing labs if there is going to be rain or even a chance of a thunderstorm.

      4. Since Lab 1: Constellations is the ordinary first lab, really the only alternative if you are clouded out is the ordinary second lab, Lab 2: The Sky.

        Unfortunately, Lab 2: The Sky is a bit of a long and tedious lab, but the students do need to cover the topics in it early in the course.


  5. Task Master

    1. Task Master:

      All the Tasks are linked here so that you can find them in the context of the lab exercise---which should be useful when completing your Report Form.

  11. Post Mortem

  12. Below are some generic comments for
    Lab x: xxx that may often apply.

    Any that are semester-section-specific will have to added as needed.

    Comments:

    1. Try harder.
    2. Be better prepared.
    3. Demand that the instructor be better prepared.
    4. Everyone should contribute to completing the Tasks and finding the answers. You should NOT just copy answers uncomprehendingly from other report forms.
