In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

In this activity about cartography, learners work in teams to create two different map projections: a planar (or polar) and a cylindrical (or Mercator) projection.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.
