Middle School Earth Science Lab: 3-page STEM packet on magma viscosity, silica composition, slope vector forces, volcano landforms, & speed math.
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)!
What Is Included in This 3-Page Packet?
