Volcanic Magma Viscosity STEM Challenge (ESS02) | Middle School Earth Science (Grades 6-8)

? VOLCANIC MAGMA VISCOSITY STEM CHALLENGE (ESS02)

3-Page STEM Activity | Print-Ready PDF Format

Explore fluid dynamics, magma composition, and volcanic landform mechanics! The Volcanic Magma Viscosity & Slope Flow Challenge (ESS02) challenges middle school student teams to act as volcanologists, testing how fluid viscosity and incline slope angles control lava flow speed down a 30 cm model ramp.

Students explore magma viscosity (felsic vs. mafic), silica content, fluid internal friction, slope vector forces, shield vs. composite volcano formation, and flow speed math (Speed = Distance / Time)!
