Ozark Karst: A Fragile Landform
Young geologists become familiar with the Karst Topography in the Ozark Mountains. They study how human activity has affected the cave ecosystem. They conduct a simulation in which a large development is proposed in the area, and they...
Curated OER
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...
Curated OER
Cave Formation Age Estimation
Students 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 and...

Water Creates a Cave
Students study the role of water in limestone cave formation and create a cave on karst-like grid on paper.
Curated OER
What is a Karst?
Students examine the process that creates limestone. In this limestone lesson plan students complete a worksheet and participate in a lab activity.
Curated OER
Acid Rain
Learners perform experiments to determine how different acids cause acid rain. They measure the pH of the water to calculate the water's acidity. They discover how acid rain dissolves rock materials.

Bryant Creek Watershed Project - Making a Karst Dictionary
Learners explore the definitions relevant to Karst topography. They develop a Bryant Watershed Dictionary of the special words and terms that are used to talk about the topography and hydrology of the area they live in.

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.

Weathering of Limestone
We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...
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.

Bermuda: Search for Deep Water Caves 2009: Out of Darkness
Students analyze the three models on the origin of troglobitic fauna. In this life science activity, students also consider how the Zonation model explains the fauna's origin. They also use the Internet to research solutional and...

WS 8.9 Presentation Questions
In this mixtures worksheet, students answer twenty three questions about student presentations on topics such as amalgams, homogenized milk, antifreeze and coolants, soaps and detergents and water softeners.
