Microplastics and zooplankton
Brainy Briny Fake Fluorescent Food
See plastic inside a living animal.
Brine shrimp eat whatever small particles are in the water, including plastic. This kit feeds them harmless fluorescent particles that stand in for microplastics. Under a black light the particles glow inside the animals, so students see bioaccumulation happen instead of hearing about it.
The kit
What the fluorescent food lab does in a classroom
What students see
Glowing particles inside the gut of each brine shrimp under a black light.
What students measure
How many animals took up particles, and how that changes with time and amount.
What it teaches
Microplastics, bioaccumulation, food webs and human impact on the ocean.
The kit, refills and workshop
Fluorescent Microplastic Powder
