STEM Activity of the Week

Hudson River Park's STEM Activity of the Week offers free online resources for students and families to learn about the Hudson River. With many learning opportunities moving to online and virtual platforms, we have started this series to share a hands-on activity that is a fun and engaging way to connect with the Hudson River.

Check back weekly for new lessons focused on Hudson River ecology, Park research and sustainability, and be sure to check out our previous activities.


STEM Activity of the Week:

Build Your Own Plankton

Plankton Building

Did you know that the greenish hue of the Hudson River Estuary is an indicator of health rather than toxicity? Microscopic plants and animals, called plankton, give the River this color. Plankton are the foundation of the Hudson River food web; they provide food and oxygen to a variety of organisms. In this lesson, students will learn about two categories of plankton–– phytoplankton and zooplankton––  and discover where in the Hudson River these tiny organisms are most abundant, and build their own plankton using common household items.
 

Theme: Plankton; Phytoplankton and Zooplankton; Buoyancy; Food Web; Water Quality
