Objective
The purpose of this project is to determine if artificial light has an effect on the migration pattern of Daphnia in a simple laboratory experiment, in a simulation of a pond habitat, and in their natural pond environment.
Experimental Procedure
The experiment had to be done in two phases. First, the Daphnia's natural migration pattern was observed. Then the effect of artificial light on these patterns was studied and compared to the original migration pattern. Daphnia were observed in test tubes and then in 3-foot columns of water and in their natural pond environment during the day and at night. Five different artificial light sources were introduced and the Daphnia were observed.
