     This extra credit project is intended to introduce you to the World
Web while at the same time teaching you some interesting facts about
astronomy and allowing you to see beautiful astronomy pictures which
you might not otherwise see in your textbook or in class.  This lab is
worth half a lab grade.  You should make sure your TA knows that you are
planning on doing this lab and turn in this sheet in order for him/her
to keep track of extra credit points.

     Please allow yourself two hours to complete this extra
credit exercise.  The computer lab on campus in Jacobs Hall has Macintosh
computers available with all of the appropriate software.  Those more
comfortable using PC's are welcome to use Explorer. We will assume that
you are familiar with web surfing, and you do not need assistance. All web
browsers work in a similar fashion--there is a box to enter a web address.
To start this exercise type in the following address:

\begin{center}
    http://astronomy.nmsu.edu/astr110/www110.html
\end{center}

This will bring you to the Astronomy 110 World Wide Web (WWW) exercise.
Once you are here, you may click on the underlined boldface titles
called links ("Picture of the Day", "NSSDC Photo Gallery", etc.) and
explore these sites, then return to the 110 exercise page by hitting the
"Back" button.  Note that you may have to do this a few times before you
are returned to the Astro 110 WWW page.  Some of the links may open up a
separate Netscape window, so if the back button doesn't work, just look
to see if your original window is behind the one you are looking at.
Once you've explored a page, answer the question related to that page
in the box provided.  Use the mouse to click in the box; this makes the
box active and anything you type will appear in this box.  Make sure that
when you click in a box you see the cursor appear and that when you type
you are able to see the text.  If this is not so, double check that you
have clicked in the box you are typing in.  Otherwise you may be typing
in a previously active box.  You may also want to write your answers down
on a piece of paper in case the answers you typed for earlier questions
gets erased.  This should not happen, but if it does, just answer the
questions on a piece of paper, and then type them all in at the end.

     When you are finished with the six sections, type your name,
professor's name, and your TA's name in the appropriate boxes
(to go from one box to another, either click in the new one with the mouse, or
simply hit the ``Tab" key). We
would also appreciate any comments and/or suggestions you may have
on this exercise and homepage.  Once you are all done, print out the
entire lab and hand it in to your TA. 

     We have also provided you with some fun and/or useful links for
your own browsing.  If you enjoy the project and want to see more, click
on the "What's New" and "What's Cool" boxes in the second row of
buttons. There is a lot of information out there on the internet -
now it's at your fingertips!

     Once you've completed the exercise, a print out of your answers must
be turned-in to your TA in the Astronomy Department. It's best
to hand this sheet into your TA when you've finished the project.
Your TA will look at your answers and give you
extra credit points based on these answers.

     If you have problems with this exercise, don't hesitate to ask the
Jacobs Computer Lab personnel for help.  They are well versed in the use
of web, and if you explain to them that it's for a class, they will
be more than willing to help.  On the other hand, try to figure things
out for yourself first - this is your project, not theirs!
