πŸ’‘ What's Happening?

When a volcano erupts, melted rock called lava flows down the mountain. How far and how fast it flows depends on what the lava is made of and how steep the mountain is!

Try moving the sliders and watch what happens. Hot, thin lava flows fast. Cool, thick lava moves slow β€” like cold honey!

πŸ“‹ Standards Alignment β€” K–5 Science β–Ό

This simulator aligns with earth science and natural hazards standards across multiple state frameworks. New Jersey, New York, North Carolina, and Michigan have all adopted the Next Generation Science Standards (NGSS) or closely aligned frameworks. Georgia uses its own Georgia Standards of Excellence (GSE) which parallel NGSS in Earth science scope and sequence.

NGSS β€” Next Generation Science Standards (adopted by NJ, NY, NC, MI and aligned by GA)
2-ESS1-1 β€” Use information from several sources to provide evidence that Earth events can occur quickly or slowly. (Volcanic eruptions as rapid Earth events)
4-ESS2-2 β€” Analyze and interpret data from maps to describe patterns of Earth's features, including locations of volcanoes and earthquakes.
4-ESS3-2 β€” Generate and compare multiple solutions to reduce the impacts of natural Earth processes on humans. Assessment boundary includes volcanic eruptions.
5-ESS2-1 β€” Develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact.
