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. Community Contacts Mike Willard John Story Ellen Turner
