Scum
He may look like the scum of the earth, but once you cross paths he's sure to grow on you.
Children, parents and educators will enjoy using these educational
plush toys to teach about hygiene, disease and the human body. Each
microbe comes with a description of the disease it causes or function it
performs. Use these fun, non-threatening toys to emphasize the
importance of washing hands and preventing sickness in social settings. Surface wash, air dry. Single celled
algae are known scientifically as phytoplankton, or “plant drifters.”
Biddulphia is a type of phytoplankton that can be seen as light brown
scum on the walls of your fish tank! In the ocean, they are often found
attached to surfaces such as seaweeds or rocks on the seafloor. |
