The rules of the class are simple.  Make sure you follow
them so you don't wind up in doo doo.  Here they are:

* No gum chewing in class.
* Do all your homework.
* Don't throw paper into the garbage can from your seat.
* Please don't talk when I'm talking. (Raise your hand,
doofus!)
* Bring materials to class.
* No swearing.
* No licking the floor.
* No licking your desk. (Unless we're doing the desk
   licking lab, of course.)
* Keep your fingers in your own nose.
* No pulling hair. (Unless you have a note from home
   saying that you can pull hair.  In that case, you can
   pull anyone's hair in the room, unless they have a note
   from home that says that you can't pull their hair. 
   However, they can pull your hair, unless the date of
   your note is before the date of their note.  If that's the
   case, you can pull their hair even if they have a note
   that says you can't.)
* No eating within 48 hours of coming to science class.
* Absolutely no blinking during class.
* No swimming in class unless you have a swim cap.
* If you bring a blender to class, you must have your
name on it.
* Absolutely no fishing until free time.
* No avocado stories or jokes about avocados.
* No doing anything that I don't like.  I may like
   something one day, and not like it the next.  If that
   happens, you can only do the thing when I like it.  If
   you do the thing when I don't like it, you're in trouble.
   Also, I won't tell you the things I like and the things I
   don't like.  You have to figure them out yourself.  I
   may like something that someone else does, but may
   not like it when you do it.  I may not like you.  If that
   happens, I won't like anything you do and you'll
   always be in trouble.  I may not like you at first, and
   then grow to like you.  Or, I may like you at first but
   then change my mind and decide not to like you. 
   Sometimes I just get in a bad mood and decide not to
   like anyone that day.  If you're worried that I may not
   like you, it's probably best just not to ever speak to
   me.  That way, I'll never get to know you well enough
   not to like you.
