Quizzes are GOOD for you!

They keep you on your toes, they prevent you from studying only on the eve of big exams, and they serve as practice for the exams themselves.

Give this one a try and email your answers to me for grading. If it helps, print the quiz out first. Your answers are due by Thurs, 8am.

**While I have your attention, please clean the mess left on the wood table near the aquariums in lab 109. As explained in the syllabus I handed out, penalty points will be assessed for the entire class if I have to clean up for you. Please have this done by Thurs, 8am. Thanks.
