pH Intro to AP2 Lab: Blood, heart, lungs, digestion, urine, pH, etc. Be active. Talk it up! Make it fun! Compared to AP1 lab… Bring to lab: Lab Activity Sheets printed from WOL Text book or images from other sources Quizzes 9 weekly quizzes = 900 points Comprehensive Mid-Term = 150 points Comprehensive Final = 150 points Lowest score dropped. Remainder divided by 1100. How to makes A’s on your lab quizzes: Learn all you can while instructor is in room to confirm. Make audio/video recordings. Take pics. View videos/etc. on Web of Life and my web page. Attend SI sessions. Make an ‘A’ vs. ‘B’ or ‘B’ vs. ‘C.’ Quiz each other until you get everything right every time. This lab room is available for your study groups most of the week. Leave lab clean and well organized. pH Acids Bases
