Andando a deriva- Experimento de plâncton
Target Group: Middle School
Ocean Literacy Principle: 5
Students build their own models of plankton from aluminum foil. The students are challenged to create a model that floats, but starts sinking after a while, mimicking the plankton behavior.
Repeat the experiment with salt water and add soap to the water and discuss the influences of these additives. Students calculate the speed and distance plankton moves.
Plastic containers or buckets, aluminum foil, salt, stopwatch (or mobile phone), projector and computer or printed version of images of plankton
