Catalog Description: Elementary descriptive astronomy emphasizing appreciation of the earth's relationship to the universe. Information collection and data analysis techniques utilized in astronomy. Lecture discussions cover the basic laws of physics, the solar system, stars, nebulae, and galaxies; the origin and evolution of the universe; the possibility of life throughout the universe. Laboratory exercises in the use of celestial coordinates; the determination of time and position, studies of stellar photographs and spectra. Field trips to area observatories and occasional evening assignments for observation. 4 semester hours
My Description: During this course we shall look up at the stars and answer the question, twinkle twinkle little star how I wonder what you are. We will also find out where to look for what in the sky and why some things are more easily seen in certain parts of the sky than others. We shall assemble a celestial sphere. Since almost everything we know about the cosmos comes from observing electromagnetic radiation (light), we shall spend some time studying and observing the properties of light. Many of these properties are outside everyday experience. We shall see how spectroscopes are used to break light apart by wavelengths and how different gases have unique light signatures (spectra) when excited. We shall assemble a spectroscope. We shall assemble a simple telescope of the same quality as Galileo used in 1610 to revolutionize our understanding of the universe. We will learn how to use an ancient astronomical calculating machine called an astrolabe, the earliest personal computer. With this we can predict the position in the sky of stars and the sun. We will measure the brightness and color of an open star cluster by running a computer program that is a virtual reality. We will measure the period of the orbits of the four bright moons of Jupiter by running a computer program that is a virtual reality. We will measure the orbital period of the planet Mercury by running a computer program that simulates bouncing a radio pulse sent from a radio telescope from Earth to Mercury and back. We shall see how and with what precision distances to planets, stars, galactic star clusters, globular star clusters, galaxies, metagalaxies, and super galactic clusters are determined. We shall see how color, temperature, mass, brightness, chemical composition, and age all affect stars. We shall have fun while doing this.
Clientel: Anyone who wants to understand the bigger universe outside of this planet.
Prerequisite: Willingness to read, think, and communicate.
Course Materials
Montgomery College has a policy of encouraging writing across all
curricula.
The AS101 Electronic Portfolio a written record of your AS101
study
and learning. Keeping this electronic portfolio will help you learn
astronomy
and keeping a portfolio in any class will help you understand and
remember
the course material. It will also help you get a substantially higher
grade
in the course. It will consist of several parts. Your portfolio will be
organized in chapters similar to the chapters in the book and it will
have
the following subsections in each chapter. If you are still "old school" or not yet
prosperous and do not own a laptop or palm computer you may want to
make you AS101 Portfolio on paper in a 3 ring binder. Many students in
past semesters have made an A using 3 ring binders.
Some students have made an A with their AS101 portfolio on a
laptop. You may even take the exams midterm and final on your
laptop or on paper the way most people still do. I write the test
as a Microsoft Word file. USB keys, diskettes, zip disks, and wireless
Internet connections are all possible ways of getting the test on your
machine in the planetarium. One student has made an A with his
electronic portfolio on a Siemens SX-56 pocket pc phone. I think
he did the writing on a regular laptop and just downloaded the files in
Word to his phone. He did take the midterm and final on paper,
though. I am technologically savvy and opened to creative
students figuring out other possibilities, too. Spiral bound
notebooks are not suitable as AS101 portfolio, because you can not
rearrange things!
1. Notes in outline form of the chapter. You should also include questions in here about things that you didn't understand when you read the text. These questions you will ask me in our threaded discussions. I like to answer questions. Make me happy. Everything, definitions and all, should be expressed in your own words. You need to make astronomy real to yourself. Writing about it will help you do this. You have to organize your thoughts to write about them. Write as you read, please. Do not read an entire chapter in the text before summarizing it. Summarize subsections before going on to the next subsection. If you have never studied this way before, please start doing it this way. You will lean more, remember more, and understand more. You will even work less for the same letter grade!
2. Vocabulary words defined in your own words. Most of the vocabulary words will be in bold face type the first time they are used in the text. Do not copy the definition out of the glossary. I will consider that plagiarism. You may want to look in the glossary to see if you have captured the essence of the word. For you to really understand the meaning of astronomy's words and terms you must express it in your own words--have faith in your own expression. Your expression of a definition will be better for you when done right than Dr. Seeds (the textbook author) definition in the glossary, which is after all best for him not you; but it can be used as a check to see if you have got it approximately right.
3. Laboratory exercises that you do. Always make a copy of your labs before you email me a copy.
4. A recapitulation or synthesis of all of the important ideas summarized in the chapter. You do this only after items 1--3 are finished. You should use this to study for test taking.
Besides items 1--4, which are done on each chapter in the text, the journal will contain laboratory exercises from The College Astronomy Kit, and all other labs like the CLEA, Contemporary Exercises in Astronomy, that you will install and run on your computer. But you don't own a computer, don't worry, all of the CLEA labs that we will do are installed on computers in the Math/Science Learning Center in Science North. The Math/Science Learning Center is opened 6 days a week! Some of the most interesting things we will do all semester will be in these laboratory exercises done on a computer.
Remember this is ultimately a portfolio for you. You can use your AS101 portfolio on the tests!
This means that my test do not require you to memorize crap that you
will forget at the end of the class. This does mean that I can ask you
really hard questions on the final exam like: "Compare and contrast the
atmospheres of Mercury, Venus, Earth, and Mars." To answer
this question you have to know the composition (what is in the
atmosphere, they are not all the same) and the pressure and temperature
of each of these four planet's atmospheres. Who remembers
details like that? I don't, (and I have spent more than half a
lifetime studying this stuff) but I know how to use it when it is in a
clear table that I wrote or you wrote in an AS101 portfolio. This
is real science, not just memorizing temporarily a few cute facts that
will soon be forgotten. It should be clear and neat enough so
that not only another student can
understand what you are doing, but that you can understand what you did
when you look at it ten years from now. A follow up question
based upon the previous question is: What three properties of a planet
and what two physical laws make a planets atmosphere?

What this course is not:
This course is not Introductory Astrophysics, that
is a three hundred level course that you could take at the University
of Maryland at College Park as a Junior. This course is
Introductory Astronomy a one hundred level course designed for
nonphysical science majors. Physical Science majors and
mathematicians may take the course, but it may not count in their
curriculum at
a transfer school for your B.S. degree. It
does count at
Mathematics
requirements in AS101 are modest, the
student must be able to add, subtract, multiple, and divide and
substitute
numbers into a simple formula. No
algebra is required to make an A in the
course, students do not have to know how
to solve
for an unknown variable in a simple linear equation like Ax+B=C. If students are
given the formula x=(C-B)/A
in some
astrophysical context and are given A=2,
C=9, and B=5,
they should be able to calculate that x=2.
Get out a calculator right now and see if
you can do this. Hey, I bet you can do this even without a
calculator. Looks like you have the ability to make and A in this
course if you do the work! AS101 students will have to use a
scientific
calculator on three CLEA, Contemporary Laboratory Exercises in
Astronomy, lab projects to add, subtract, multiple, and divide.
There is a TI scientific calculator chained down in the
Math/Science Learning Center in Science North Room 100 in case you
forgot to bring your calculator when you need it. I know, I put
it there several years ago, and I occasionally change the batteries so
it continues to work. On tests AS101 students will not
have to do arithmetic
more complicated than to multiple an integer time itself four time,
like 3^4=3•3•3•3=81
(for Wien’s law, how much brighter is one star than another star if it
is three times hotter in absolute temperature and the same physical
size?), or to calculate a simple reciprocal like 1/(1/3)=3
(for
understanding how to calculate parallax distances from arc seconds into
distance
in
parsecs, what is the distance in parsecs if the parallax of a star is
observed to be 1/3 of an arc second?). Any
physical principles
(physics) that they need to understand the material in AS101 are taught
in the course.
Physics is not a prerequisite, so knowing some physics before you
take the course is not required to make an A. Of course
if
you know some physics it will not hurt you
either. You will actually learn a
little physics in a fun non threatening
way in AS101.
AS101
students need to be able to read a text
book with some understanding, and to be bold enough to ask questions in
class
about anything they did not understand in the text; or to have a friend
in the
class who is bold enough to ask the question for them.
Students are not required to memorize crap,
portfolios with notes the student have written, with diagrams and
graphs from
the text that the student deems important,
vocabulary words defined by the student, and completed labs may
be used
on the tests. The portfolio may be in a
bound form like a three ring binder and written by hand or typed; or it
may be
on a computer organized by chapter in the text organized by the student. Portfolios are part of the writing across the
curriculum taken seriously in AS101.
Students with all types of the afore mentioned portfolios have
gotten As
in the class, since they have answered the questions on the exam mostly
correctly. The questions on the exam are
not always simple identifications of crap easily memorized and
forgotten the
next term. "Education is a permanent
alteration in behavior" and this course alters behavior of successful
students,
which is the majority of the class. Not
reading the text always leads to failure as the instructor does not
read the
text to students, but expects them to read the assigned portions before
coming
to class; and to have understood it before the exams, which does take
some time. Some exam questions
require a
few sentences to answer or a labeled diagram to be sketched. No great artistry in diagrams is required and
spelling and grammar are not graded as long as the instructor can
understand
the sentence or phrase.
This course can be
great fun
for anyone who wants to understand something about where and when and
how they
fit into the larger universe. Artist,
accounting majors, business majors, computer science and computer
application
majors, history majors, future teachers (AAT=Associate Arts in
Teaching), and practically any other type of person can do well in
this course if they study some and try and figure things out with the
help of
their fellow students and the professor some things about the way the
universe works.
Studying in groups is encouraged, but not mandated.
The CLEA lab projects may be done in groups as
large as three persons using a computer in the

Extra Credit Opportunities
The Washington Metro area is currently the naval of the planet earth
(the capital of the only remaining superpower) and is culturally and
scientifically
one of the richest places. Write at least one page (around 250 words)
about
what you learned during an astronomy lecture or a clear night viewing
through
a telescope at an observatory. Please draw a sketch of anything that
you
saw though a telescope. Send me a copy, but keep one for yourself as it
belongs in your journal.
Math Science Learning Center at Takoma Park/Silver Spring, SN101
As you may need some assistance in understanding some labs and as three
labs are done on the computer the Math Science Learning Center, MSLC,
in
Science North Room 101 has the computer astronomy labs already
installed
on at least 20 computers. There is also a "Learning Technologies"
assembled
celestial
sphere, assembled telescope, and assembled spectroscope and other
helpful aids in the MSLC to help you study for the
exams
and to do the labs. For MSLC hours see
http://www.montgomerycollege.edu/Departments/mslc/. The MSLC
hours will most likely be Monday through Thursday: 8:30am-7:00
pm, Friday: 8:30 am - 3:00 pm, Saturday: 10:00 am-4:00 pm, and Sunday:
closed. Check the web for possible changes in hours of
operation. Nice computers and nice people, but do not expect them
to know enough
astronomy particularly the details of the CLEA labs to help you do more
than find the icon to click on the computer. Be courteous and be
finished before they close and have to tell you to leave. They
have a life to just like you.
Student Technology Center, ST304
Another
computer lab that has computers for you to do the CLEA labs on.
They are even open on Sundays on the third floor of the new Student
Services building. Monday through Thursday 7:30am-10pm, Friday 8am-5pm,
Saturday and Sunday 9am-5pm. Nice computers and nice people, but
do not
expect them to know enough astronomy particularly the details of the
CLEA labs to help you do more than find the icon to click on the
computer. Be courteous and be finished before they close and have
to tell you to leave. They have a life to just like you.
