Advanced Placement Biology

Prelab Instruction

A compilation by:Virginia Vilardi

Introduction

• Advanced Placement Biology is the equivalent of a college freshman level course. As such it must also have the lab component that goes a long with it.

• This presentation is geared towards introducing the student to each of the labs as well as helping them through the procedure and data analysis.

• Much of the material is taken from Campbell’s Biology 7th edition online teacher’s help. The online help goes along with the Campbell’s Biology 7th edition the most used book for AP Biology.
