In this NASA Spotlite, NASA interns challenge the question: Where can you find phytoplankton? Through a simple investigation, viewers learn how to collect water samples and observe them to look for phytoplankton.

Phytoplankton are tiny plant-like organisms that live in water and play an important role in Earth’s oceans and ecosystems. Viewers are encouraged to explore local water sources and investigate whether they can find phytoplankton in their own samples.
