JUNIOR Environmental Engineering STEM Project: The Algal Bloom Challenge
Imagine looking at a local river and seeing the water turn a thick, neon green. That is the image we presented to our 5th graders to kick off their latest science unit. We challenged them to become environmental engineers . In this post, I want to share a STEM project I designed with my colleagues, Jessica Jordon and Courtney Gienapp, where students didn’t just study algal blooms — they designed real solutions to stop them. To kick things off, we started with a “provocation.” We showed students images of algal blooms in Singapore and around the world. Although we couldn’t go on a field trip this year due to restrictions, the visual impact of the discolored water was enough to generate curiosity. The Inquiry Cycle This provocation led to three main categories of student questions: The Cause: What is algal bloom and what causes it? Plant Growth: What makes the algae grow so fast? Consequences: How does this contamination affect the ecosystem? Students researched how nutrient-rich ...
