How Do Diatom Reproduction React to Variable Amounts of Light?

Science Fair Project Information
Subject: Botany
Grade level: Middle School - Grades 7-9
Academic Level: Ordinary
Project Type: Experimental
Cost: Low
Honorable mention at the Greater Vancouver Regional Science Fair
The Cryptozoology Award.
Affiliation: Canada Wide Virtual Science Fair
Description: A few flasks, each containing diatoms (Odontella longicruris), are exposed to different light conditions for a few days. The color of the diatom culture, measured by a light spectrometer, is related to the number of the diatoms because of the chlorophyll they produce when exposed to light in the photosynthesis process.
