Photosynthesis Lab
Instructor: Mrs. Turner
Principles 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.
