What are two things you do ahead of time to prepare for a lab

- - Review the part of the book and your notes that deal with the lab topic.

- - Read the lab exercise so you know what you'll be doing in lab today.

- - Gather up everything you'll need to have there ... not the stuff like

chemicals or equipment that they'll give you in lab, but the stuff that

you're expected to bring; like pencils, lab notebook, scratch paper,

your calculator, a ruler, things like that.

- - Go to the bathroom.

Wear your proper gear and gather all nessesary materials with instructors permission.
