Exploring Life - Honors Biology Chapter 14

When you click Submit (at the bottom of this web page) it will save your work on the server for me. If you get a "proxy error" hit -refresh- until you get a "Thanks"

You might want to actually write your answers in Word (so you can spell check them) and then cut-and-paste into the boxes. That way, if the computer misplaces your work you can just re-paste the answers.

Since this is extra credit I would appreciate it if you only submit it when you have completed all the questions.

DO NOT JUST LOOK FOR THE ANSWERS…YOU’LL MISS LOTS OF IMPORTANT STUFF. THE QUESTIONS ARE JUST TO KEEP YOU “HONEST.”

TAB OR USE THE MOUSE Between the fields....

Answer the questions as best you can. The boxes will expand as you type if you need more space. (Don't worry if it is a one word answer. The box size is standard.)

Although you can work in pairs for this extra credit, if you do, your answers have to be very good to get full credit. No groups of more than two will be accepted.

Remember, the boxes will expand as you type if you need more space.  Also remember that although some of the answers may only require a single word (or number) the box size is standard, don't feel you have to fill it. Answer the questions as given.

You can work on this from home once you have signed up for Successnet.

Open SuccessNet in a separate window . (If you need help with that ask.) Later you may want to open the Explore Life CD in a separate window  (If you need help with that ask.)

If you have already signed up for SuccessNet, you can access the assignment that way, and also work from home (or library).

While there are questions on the CD, they provide answers, so I can't grade their questions. You will get a grade for the answers on this form!
