This laboratory is a one-semester complement to ASTR 110 lecture, Survey of Astronomy, an introduction to planets, stars, galaxies, and cosmology. Co- or prerequisite: ASTR 110 or equivalent, or consent. Our course will cover the apparent motion of the night sky, Moon, and planets; major constellations and bright stars; binocular and telescopic observation of fainter objects; and basic scientific and astronomical techniques. We will perform both one-night and long-term observing projects, as well as some indoor exercises. Our schedule will be subject to frequent revision based on weather and astronomical events, and will not be synchronized with any ASTR 110 lecture section.
Equipment
& Materials
REQUIRED
TEXT: Ridpath, Stars and Planets, 4th ed. (2007), paperback: ISBN 978-0-691-13556-4
REQUIRED MATERIALS:
• Pencil and
eraser (for in-the-field sketching; pencil also has the advantage of being
waterproof!)
• Scientific calculator (capable of power-of-10 notation and advanced math functions; only needed occasionally for calculations at home)
OPTIONAL MATERIALS (but highly recommended!):
• Warm clothes
(especially during winter, and on windy nights)
• Beach mat,
towel, or picnic blanket (for sitting on moist grass outdoors)
• Clipboard or
hardcover notebook, with metal clips or clothespins (makes in-the-field
observations and sketching much easier on windy nights)
• Folder or 3-ring binder (for organizing lab
handouts, and for safekeeping of long-term projects)
You will be provided with 8-inch Dobsonian telescopes & eyepieces, 10´50 Binoculars, red flashlights, and other observing equipment as needed in
lab. You are welcome to bring your own
binoculars, telescopes, and red flashlights, if you wish. Note:
White flashlights, cell phone lights, etc. are FORBIDDEN in lab, except during
clean-up!
Please
return all equipment in good condition at the end of the
night — it must be used by students in all three lab sections. Please report
any problems or breakage to your
instructor or TA; do NOT allow the broken equipment to be stowed away only to
become a rude surprise for the next night’s lab.
• Your final grade will be based on your overall course percentage: the number of points you earn divided by the number of points possible. An overall percentage of 90% will guarantee you at least a final grade of A–; of 80%, B–; of 70%, C–; etc. In the final determination of grades, these cutoffs may be lowered at the discretion of the instructor. Your overall course percentage will be weighted as follows:
Quizzes 30%
Assignments
(Worksheets, Sketches, Lab Reports + Extra Credit) 70%
Attendance see
below
• Quizzes will be given most weeks at the
start of lab in PSB 112, and will be short, 10-minute tests usually based on
the material covered the week before, or possibly a pre-lab quiz on the
material assigned for that same night.
You will be given advance warning about the topic(s) of the next
quiz.
Quizzes may
not be made-up for any reason, but all quizzes will be worth the same
weight, and your TWO lowest quiz scores will
be dropped.
• Worksheets & sketches will be short
assignments to be completed either in the field and/or during the week as
homework. They will typically be due the
following week, although due dates may be postponed due to weather. The number of points that each assignment is
worth will vary, depending on the amount of time and work that it
requires.
Some
missed assignments or observations can be made up during future lab sessions
or at home (see your instructor individually for details); any portions of
assignments that cannot be made up will be given a score of zero.
• Extra-credit: A few activities will be optional, especially if they involve meeting at
a time outside of regular class hours to observe a special astronomical event,
observe the Sun midday, or to attend a public lecture. By completing optional activities, you can
boost your Assignment point total and potentially make up for missed work. (Extra-credit points will not affect your Quiz point total, only
your Assignment total.)
• Lab reports may be assigned at the
culmination of some long-term projects.
Lab reports should be short (two or three-page) reports in which you
present the results of your measurements or observations, and will follow a
simplified science lab report format (introduction, procedure, observations,
analysis, conclusion). More details will
be provided on the format to follow and the content required for each
report. Since writing the reports
requires additional time and preparation at home, the lab reports will be worth
a correspondingly greater point value than other worksheets.
• Late assignments will be penalized with
a –5% deduction for each weekday
past their due date, which corresponds to a 25% deduction per week. Due dates may be extended for the class as a
whole, based on weather or other problems; or for absent students on an
individual basis, based on the nature on the assignment. However, once a due date is set, penalties
will be applied after that date. You may
turn in assignments at any time during business hours by sliding them under my
office door, Watanabe 423, whether I am in or not.
• Exams: There will be NO midterms or
final exam for this lab.
Attendance will be taken at all lab sessions.
We will have indoor activities in PSB 112 in case of inclement weather,
so you should plan to attend lab every
Wednesday night, rain or shine! We
will meet every Wednesday from August 26
to December 9, except for November 11 (veterans day). We will NOT meet during finals week.
While
your attendance will not be used directly in the calculation of your overall
course percentage, it may be used as a factor in determining the final grade
for “borderline” students. Participation in lab is essential to
gaining familiarity with the night sky and with the tools of astronomy.
Missed
quizzes cannot be made up (see
“Quizzes” policy above). Some missed worksheets, sketches, or
other observations can be made up, either in part or in full (see “Worksheets”
policy above). (New due dates will be
determined individually in each case.)
Some observations and projects, however, are one-time-only and are
therefore impossible to “make up”; you will simply receive a zero score for
that assignment (or portion thereof) that cannot be redone.
If you
know in advance that you will be absent for lab, please contact your instructor well ahead of time to discuss making up
work. After an unanticipated absence,
please e-mail or contact your instructor
as soon as possible — do not wait
until the following Wednesday night!
Working in pairs or groups is common in science labs, and indeed is encouraged: teamwork can help you to make measurements faster and to catch errors, and explaining something to another person is a great way to learn it better yourself. However, even if you are “working with” a classmate while using the telescope or making a measurement, there are a few guidelines to follow:
(1) You
are each strongly encouraged to make the observation yourself,
individually, so that you each get the educational value and experience of
using the equipment and “seeing for yourself.”
Then, after you have each tried, you can compare your results as a
“sanity check.” If your results differ
just a bit, then keep your own results
— most scientific measurements vary slightly due to “random error” (we will
discuss this later), so you should not
change yours to match your friend’s result.
After all, how do you know which result is “correct,” yours or your
classmate’s? Record what you see or measure. (If your results differ wildly, then in that case it is appropriate to try to figure out
“what went wrong.” Small variations,
however, are common and are a natural part of random error.)
(2) Any
final work (lab reports, worksheet answers, etc.) should be in
your own words. If you do work
together with a partner to make a particular measurement or observation, make a
note on your worksheet or lab report of who your lab partner was. Again, complete the final report or worksheet
in
your own words, even some of the initial data or measurements are
identical to your partner’s.
Any
passages or calculations that are simply copied
or plagiarized from another student, or from any other uncited source (textbooks,
encyclopedias, websites), will be given a score of zero. Your submitted work
should reflect your own understanding of the material.
OPTIONAL
TEXT: Gupta, ed., Observer’s Handbook 200_ current version is best
OPTIONAL
TEXT: Rhoads, The Sky Tonight, 3rd ed.
(2000), paperback: ISBN 0-930897-93-5
Waterproof Pen (like traditional “Bic” ball-point; for in-the-field notes; although pencil is also waterproof)
Observing
Log (any bound composition or lab book, preferably with some unlined pages)
• Observing logs are something all
professional scientists and many amateur astronomers use to record their
observations and measurements as they are making them. Your logs may be inspected (and graded)
periodically during the semester, and will be collected at the end of the
semester for a final grade. Guidelines
for observing log use will be detailed later.
