Semester Observing Project - Lab 1
Since this is a daytime lab, this semester observing project is quite
different than the one in you lab manual. The primary focus of this lab is to
become familiar with the objects in the sky above you; we often go about our
lives without ever actually looking at what is above us. We will become familiar
with the two most prominent objects - the Sun and the Moon - as well as many of
the constellations.
The lab consists of three sections:
- Solar Observations - 50 points
- Moon Observations - 50 points
- Constellation Observation - 50 points
Solar observations will be performed during class using a sunspotter;
the Lunar and Constellation observations will be done on your own.
Solar Observing
This portion of the observing project will be done entirely during class and
is quite straightforward. You will keep a running log of your observations which
I will collect at the end of the each class in which we do observing. Each week
you will do these two activities:
- Sunspot Observing: You will observe the Sun with the aid of the sunspotter.
Through these observations, you will see that the sun is quite dynamic
and that the sunspots do not stay in the same place. I will be telling you a
bit more about the Sun throughout the semester, so that these observations
will complement the main part of the course.
- Solar Position: You will also measure the position of the sun (S, SE etc) and its altitude
each week. Again, you will see that the Sun moves about quite a bit in the
sky, even when observed at the same time every day. Since it is quite
difficult to look at the sun and determine its altitude, we will be casting a
shadow of a wooden pole and measuring its length. We will go over this in
detail the first time we do it and learn how to determine the Sun's altitude
based upon the length of the cast shadow.
Each week (weather permitting), you will turn in a
detailed drawing of the sun. Since we are aiming to see how the sunspots are
changing, the locations and sizes of the spots should be accurately recorded.
You will also record the length of the Sun's shadow. Once you have completed
eight sets of these observations, you are done with this portion of the project.
Finally, you will write a brief summary describing what you have learned
through the solar observing project. I will give you more information about this
later in the semester.
Lunar Observing
This part of the observing project will be done entirely outside of class.
You must make 7 observations of the Moon, one of each phase of the Moon (you
will learn the various phases of the Moon in Lab #3). Every couple days, go out
and sketch the Moon in its correct phase. Use copies of the half-circle template
provided in your lab manual to make your lunar observations. As with the Sun,
you will also record the position of the Moon in the sky including the
direction and altitude. To determine the position of the Moon (S,
NW, etc) you must find the North Star. Please refer to the handout distributed
during the first class to figure out how to do this. I will also show you
this again in the planetarium.
As with the Solar observations, you will write a brief summary describing
what you have learned through the Moon observation project. Include the following
| - Time and Place of observations | - Partner |
| - Phase of the Moon (with drawings) | - Observing Conditions (clear, cloudy, etc.) |
| - Altitude and direction of Moon | - Any nearby prominent stars, planets, etc. |
Constellation Observing
This portion of the project consists of two parts:
- Constellation Observing: On any clear night, find your constellation and record the time
and date of observation. Also record the altitude and direction of the constellation, and
include a drawing. You should also include your impressions of the bright star(s) in the
constellation and the constellation as a whole. What color are the brighter stars? How many
bright stars are there? What does the constellation look like to you?
- Constellation Lore: Using the internet or other sources of information, find out as much
as you can about your constellation. Include background lore (Who/What was it named after?
What stories surround the person/object?) as well as relevant information about objects
found in the constellation (What are the names of the brighter stars? What other prominent
objects are found in the constellation?). I will be giving you handouts of examples from
which you can get a general idea of what I'm looking for.
Turn in a summary of your observations (with drawings) and a summary of your information
on your constellation.
