Weathering by rusting steel wool experiment explained
A science activity shows iron in steel wool rusting faster in salt water, illustrating chemical weathering. The dry piece changes least while the salt water piece changes most, mirroring rock weathering with iron-bearing minerals. The event Praxis hosts a Family Science Olympics at Medicine Hat High School with Kate Berger presenting.
