Photosynthesis Lab

Instructor: Mrs. TurnerPrinciples of Biology

Nathan Marcy Tim Waldrip Amanda Matsumura Alisa Craig

Introduction

• There is a need for laboratory reference materials in order to show to absent students in NWACC science classes. We have made a video showing a lab on photosynthesis with verbal and written directions and visual aids.

Project Overview

To indentify and describe the methods of photosynthesis presented in the lab.

To give a visual aid to learning the lab content

To give simplistic directions for completing the lab.

Community Aspect• We have helped fellow students to understand and recreate

the photosynthesis lab.

• We also gave the science department a resource to fulfill state frameworks by exposing to students who have missed the photosynthesis lab.
