Business I
• Class meetings:– Lecture MWF here– Lab once a week in Physical Sciences Bldg.– Recitation once a week in Physical Sci. Bldg.
• NO LABS or RECITATIONS this week- they start Monday
• Class Rules- Syllabus (go over on Friday)
Business II
• Be here every single day
• Be here on time
• Don’t sit in back
• Don’t talk when I’m talking
• Don’t let me talk when you’re talking
• It’s ok to get up and wander
Classroom Rules
Business III
• Homework:– OWL Electronic Homework System– First assignments due in one week
• Gateway Quizzes– First 20 elements– Tables of common ions
How to do well
• Sit in front
• Read text chapter before and after covering
• Do homework early and often
• Avail yourself of help:– me– chemistry tutors (times given next week)
• Keep up with material

Why is chemistry hard?
• Atoms are really small.
• About 100 types of atoms (each a chemical element).
• Matter is made of atoms, mostly connected together in molecules and larger structures- infinite variety of combinations.
