Presentation transcript:

Living Light:

Activity  Each group represents a different animal.  There are 2-3 groups of each animal.  GOAL:  Locate the other groups of your kind using ONLY the light pattern you were given as communication.  NO TALKING!

Activity  Why would an animal want to locate others of its same kind?  Why would it use light for this?

Euphotic Zone < 200 m “Twilight” Zone m Aphotic Zone > 1000 m
