Lesson Plans

These lesson plans are available for download to use in your classroom with your students. The following table shows which grade level TEKS each activity has been correlated with. Please note that almost all the activities can be modified to meet TEKS for other grade levels.

Activity	Activity Summary	Subjects	Grade Levels
Discovery Tour	Students will go on a guided tour through the Discovery Passages at Natural Bridge Caverns and learn how different geological processes formed the cavern system.	Science	1-8 & Earth & Space Science
Analyzing Groundwater	Students will compare the properties of different soil types including filtration rate. Students will relate the filtration rates to pollution and learn about aquifers and the impact humans can have on them.	Science	7
Analyzing Soil Types	Students will compare the properties of different soil types including texture, particle size, and filtration rates.	Science	4
Bats Need a Cave	Students will play a game to simulate how human impact can affect the habitat of bats.	Science/English, Language Arts & Reading	K-3
Cave Formation Age Estimation	Students will investigate the actual growth rates of flowstone formations.	Science and Math	8, Earth & Space Science
Clear as Mud	Students will analyze "water" samples taken from a “spring” on two different occasions.	Science	4-5
Clues From the Past	Students will simulate the work of archaeologists as they look for artifacts to describe the types of communities that different prehistoric groups lived in.	Social Studies and Archaeology	2-7
Creating a Topographical Map	Students will use clay models of a landscape to create a topographical map.	Science	8
Disappearing Rocks	Students will drip vinegar onto rocks to demonstrate the weathering effect of a weak acid on limestone.	Science	4-8
Modeling the Rock Cycle	Students will use crayons to model the processes that create igneous, sedimentary, and metamorphic rock.	Science	4-7
Momma Bat Baby Bat	Students will simulate the way a mother bat locates her baby when she returns to the nursery and relate this experience to the story Stellaluna by Janell Cannon.	Science/English, Language Arts & Reading	K-2
Moving Rocks	Students will physically manipulate clay models to demonstrate changes in the Earth's crust.	Science	3-8
Rocks and Minerals	Students will observe rock and mineral samples to learn about the basic properties of minerals and the three different rock types.	Science	4-8
Secret Sink	Students will work together as city planners to design a community. They must take into account the needs of community members, businesses and the environmental impact on the land itself.	Science and Social Studies	6-8
Sinkhole in a Cup	Students will learn how sinkholes form as well as the impact humans can have on groundwater quality.	Science	K-8
Sluice Sorting	Students will use their findings from bags of mining rough to group the rocks based on their properties and characteristics.	Science	K-1
Guide to Accompany the Tour	A guide for teachers detailing the entire Discovery Tour at Natural Bridge Caverns.	Science	ALL
Natural Bridge Caverns Board Game	Students will play a board game as a review of their trip to Natural Bridge Caverns. Questions include key vocabulary.	Science	4-8
Rocky Road Game	Students will play a board game to review the Rock Cycle.	Science	6-8
Natural Bridge Caverns Magic Triangles	Students will use manipulatives to match the term with the correct definition, example or picture.	Science	4-8

Exploring Caves Story and Activities

Students will follow the adventures of two children as they explore a cave. A talking bat serves as their guide. Students will learn the science behind caves as well as take part in various activities to increase their knowledge and appreciation of caves.
