What is a Karst
Students investigate landforms by holding a class experiment. In this topography lesson, students define the word "karst" and discover why sinkholes are created on the surface of the Earth by completing worksheets. Students create a...

Inner Space Cavern Cave Field Activity: Drip Rate Analysis
Students compare drip rates at several different locations throughout a cave. They observe, first hand, the heterogeneity in flow paths present in karst aquifers such as the Edwards aquifer.
Curated OER
Is Your Water Clean?
Students compare water quality of different sources. They test water samples for odor, phosphates, pH, bacteria, and dissolved solids. they fill out a data table and answer questions about their findings.
Curated OER
Caverns: Drip Rate Analysis
Students tour a cave and collect water samples. They measure the drip rate from several locations inside the cave and discover the part water plays in cave formation.

Cave Formation Age Estimation
Young scholars investigate growth rates of flowstone formations. They view a virtual field trip and discuss how flowstones form. They observe the cave fieldtrip and predict the growth rate for a cave formation. They graph growth rates...
