  • 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
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
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.
