Biofilm simulation at the G.C. Marine Reserve

During the biofilm experiment, I made a madel (out of grahm crackers) of what a biofilm disk looks like when sitting in the water for multiple weeks or months. Different sprinkles I've used symbelizes different organisms tthat show up on an object that sits for a long time. Red sugar crystals were red coralline algae, Brown long johns were diatoms, rainbow sprinkles and marshmellows were barnacles, rainbow longjohns were coral, blue or green dots were oysters, depending on how many organisms we had added up to the ammount of marshmellows (barnacles) were added. The frosting was used as a sticky substance.
