Earth Science

Earth science runs on processes too big and too slow for a classroom: colliding plates, erupting volcanoes, a watershed's worth of moving water. These free interactives compress them to classroom size and speed, with worksheets and NGSS-aligned lesson plans built in.

Fold Mountain Builder

Squeeze layers of rock between colliding plates and watch a mountain range fold up in front of you.

NGSS MS-ESS2-2

Volcano Eruption Simulator

Build shield, cinder cone, strato and dome volcanoes, then set off eruptions and measure the fallout.

NGSS MS-ESS3-2

Earthquake Simulator

Shake buildings at different magnitudes and see which design choices keep a structure standing.

Exploring the Water Cycle

Light up each of ten water-cycle steps in a 3D landscape, then use sun, temperature, lake size and tree cover to change how many gallons move each week.
