Hydrothermal systems

STEM Learning Module:

Ocean Silicate Geology

Using marshmallow modeling tools, in this activity students will model the formation of silicates–the family of minerals that make up more than 90% of the Earth’s crust. Silicates range from mafic to felsic. And since not all silicates are made equal, the composition of each of these minerals varies greatly on the depth within the Earth.

STEM Learning Module:

Remote Sensing

Transform your students into an exploration team by taking on the roles and dynamics of directing an expedition to study a seafloor habitat. Use the module’s provided original art printables to set-up a seafloor to observe using a remotely operated car and camera. Students will take on roles of data loggers, navigators, ROV pilots, and expedition leaders learning about remote sensing technologies, data collection, and teamwork.

STEM Learning Module:

Living on a Chimney

Introduce students to ecological relationships and organisms existing in one of the most extreme habitats on Earth: deep-sea hydrothermal vents. Using creature cards to construct a model food web with trophic levels, trophic positions, and ecological niches, students will determine the spatial distribution of organisms across a hydrothermal vent community based on provided evidence.
