Students use soil from Earth with properties highly similar to Martian soil, developed and tested by NASA, to investigate the discoveries and theories about Mars that were generated by the Viking, Observer, and Pathfinder missions. The soil can be compared with Martian soil data to discern their similarities and differences, how and from what materials it was formed, and whether the soil is able to support plant life. It comes with enough materials for ten soil tests and one demonstration planting: Martian regolith simulated soil, topsoil, planting pots, Rapid Radish seeds, soil test kit, fertilizers, and ten bar magnets, as well as a Mars globe 4 3/4″ in diameter, Mars topographic map, and study guide.
