Solving Dissolving

The Sacred Cenote at Chichén Itzá is a sink hole, or well, containing groundwater. In this activity, learners create their own cenote using chalk, limestone, acids, and rain water. A real cenote is formed very slowly over time by acidic water trickling through tiny cracks in limestone, dissolving a mineral in the limestone called calcite.
