Use fast-response temperature probes and stainless steel temperature sensors to determine and compare the specific heat of water to that of sand, as a model of land, and consider the effects of these differences on global weather and climate.
The high specific heat of water accounts for many characteristics of global weather and climate. In this activity, students determine and compare the specific heat of water to that of sand, as a model of land. Students:
