Did you know that the greenish hue of the Hudson River Estuary is an indicator of health?
This color is due to plankton, which are tiny, often microscopic plants and animals that cannot swim against strong currents. Plankton are the foundation of the Hudson River food web and provide oxygen to a variety of organisms in the River. There are two main types of plankton, phytoplankton and zooplankton. Phytoplankton are plant plankton and zooplankton are animals. Today’s lesson is a fun craft to showcase the many shapes and sizes of plankton.
