1) Regular lab discussion sessions identified in the syllabus where you will do exercises and experiments
2) Additional classes on gathering and using information, held at the library (you will need to sign up for a session)
See http://ircamera.as.arizona.edu/NatSci102/
for the course homepage which will lead you to the course schedule, syllabus, and
policies. Be sure to read carefully and pay attention to the key dates and requirements
for the course
In the lecture notes, look for the "question" button . Clicking on it will give answers to key
questions -- but try to answer them yourself first!! These questions are the highest
priority for the course -- no one can expect to do well who has not mastered them. The
second priority should be the main body of lecture notes. Additional material - the text
if we had required you to buy one - is indicated by a "book" link: 
. Please read these links along with the notes
to help you understand them. The exams will cover the lecture notes plus the
"question" and "book" links. We have also put links to extra items in
the notes. You can find them by clicking on 
These last items will not be featured on
exams, but they may help you remember the material or just be interesting or amusing. You
should be sure to include them in your studies, but don't try to cram on them for the
exams! Finally, there are a few links to much longer extra items, like the famous science
fiction thriller "War of the Worlds," which you may enjoy following just for fun
Links to sources outside the course are indicated by the full URL, to distinguish
them from the internal ones (of course, they will not work if you are not connected to the
internet!). Sometimes these links are broken because the web page has been taken down; we
keep them as a record of where the information was obtained. If you have a slow web
connection (or none) you might want to be careful with the external links. External links
will not be covered in exams, but you may find them interesting. Here is more
about the goals for the notes, some tips about running them on your computer, and how to
send us corrections or comments
Our goal is to use pictures, art, animations, scientific simulations, literature, cartoons, history, and anything else that comes to hand to help you visualize what the Universe is like and share in the fun of exploring it!
