TEKS – Inner Space Cavern
4th Grade

TEKS and Student Objectives

TEKS

(4.7) Earth and Space
B. observe and identify slow changes to the Earth’s surface caused by weathering, erosion, and deposition from water, wind, and ice.

(4.8) Earth and Space
B. describe and illustrate the continuous movement of water above and on the surface of the Earth through the water cycle and explain the role of the Sun as a major source of energy in this process.

(4.9) Organisms and Environments
B. describe the flow of energy through food webs, beginning with the Sun, and predict how changes in the ecosystem affect the food web such as a fire in a forest.

Student Objectives

During the tour:

The students will be able to describe the journey a water molecule takes on its way into a cave system and how water affects the cave through completion of The Water Cycle activity and discussion with their tour guide.

The students will be able to explain that organisms in an ecosystem are interdependent by observing the conditions of that ecosystem and applying the information collected to the Food Web activity.

Pre- and Post-Visit Activities and Assessments
The purpose of these activities is to prepare your students for your visit to Inner Space Cavern or to supplement what they have learned once you return to the classroom. Ideally, the activities would be completed in the order listed; however, each activity may stand on its own.

Pre-Visit Activities
Pre-Visit Acivity #1: The Water Cycle

Post-Visit Activities
*Post-Visit Activity #1: Sinkholes
Post-Visit Activity #2: Food Web
Post-Visit Activity #2: Food Web Information Sheets
Post-Tour Carbon Cycle Activity

*Applies to TEKS for more than one grade.

5th Grade

TEKS and Student Objectives

We have divided the TEKS into two categories. The primary TEKS pertain to the formation of the cave and its speleothems. The secondary TEKS relate to the interactions of animals, past and present, as they pertain to the cave environment.

TEKS

Primarily (I):

(5.5) Matter and energy.
D. Identify changes that can occur in the physical properties of the ingredients of solutions such as dissolving salt in water or adding lemon juice to water.

(5.7) Earth and space.
A. Explore the processes that led to the formation of sedimentary rocks and fossil fuels;
B. Recognize how landforms such as deltas, canyons, and sand dunes are the result of changes to Earth’s surface by wind, water, and ice.

(5.9) Organisms and environments.
D. Identify the significance of the carbon-dioxide cycle to the survival of plants and animals.

And Secondarily (II):

(5.7) Earth and space.
D. Identify fossils as evidence of past living organisms and the nature of the environments at the time using models.

(5.9) Organisms and environments.
A. Observe the way organisms live and survive in their ecosystem by interacting with the living and non-living elements.

Student Objectives

During the tour:

I.
The students will be able to explain how limestone caves are formed by observing the fault line and evidence of carbonic acid in the cave.

The students will be able to describe the process of the formation of speleothems by observing stalactites, stalagmites, soda straws, and other formations in the cave and by interacting with their tour guide.

II.
The students will be able to explain the process that resulted in the cave being accessible from the surface during the ice age by observing the debris cone of one of five sinkholes found in the cave.

The students will be able to describe some of the adaptations of troglobites through discussion with their tour guide.

Pre- and Post-Visit Activities and Assessments
The purpose of these activities is to prepare your students for your visit to Inner Space Cavern or to supplement what they have learned once you return to the classroom. Ideally, the activities would be completed in the order listed; however, each activity may stand on its own.

The following activities correspond to the Primary TEKS listed above.

Pre-Visit Activities
Pre-Visit Acivity #1: Limestone
Pre-Visit Activity #2: Solubility
Pre-Visit Activity #3: The Carbon Cycle

Post-Visit Activities
Post-Visit Activity #1: Where Does the Water Go
