Sandwich Stratigraphy
Two activities are included in this resource. In the first, junior geologists model sedimentary rock layers, apply the Law of Superposition, and demonstrate folding and faulting of the Earth's crust. The model is technically a sandwich....

Take a Stab!
Your geology class practices taking core samples of a potato to examine the stratigraphy. This is a terrific modeling lesson that helps youngsters visualize strata that cannot be seen from the surface of the ground. The directions...
Curated OER
Understanding Lava Layers
Seventh graders view "Volcano" by National Geographic Video. They experiment with baking soda and study lava flow. They describe volcano and earthquake patterns. They analyze weather and climate changes and how they relate to the natural...
Curated OER
Mapping and Excavating a Jello Mold
Students simulate how archaeologists excavate sites by "searching" their own site in the form of a Jello mold. They use a grid to map the objects in the Jello mold as well as looking at three layers of Jello to understand stratigraphy...
Curated OER
Take a Stab!
Students construct an experiment to test the rigidity of compressed air and its strength. In this earth science lesson plan, students are divided into groups, and by putting their thumb over the end of a straw, use the compressed air...
Curated OER
What's in the Soil?
Second graders create stratified soil levels using pictures. In this earth science lesson, 2nd graders identify "artifacts" from 3 historic eras and divide them into 3 soil levels. Then they draw their own multi-level soil profile and...
Curated OER
Relative Dating in Archaeology
Students create a timeline that explains how ancient cultures used artifacts. In this Relative Dating in Archaeology lesson plan, students examine artifacts and draw conclusions about their origins. Then students analyze antiquated...
Curated OER
Stratigraphy -- Layers of Time in the Earth
Students are introduced to the process of stratification. Using the internet, they read about the Richard Beene archeological site near San Antonio. Using a map, they color code the different layers present at this site and answer...
Curated OER
Garbage Can Archaeology
Students explore the use of stratigraphy to date objects by sorting the material in the wastebasket. They make a list of actual items from the garbage can and their possible uses and categorize the artifacts.

Developing a Local Stratigraphy
Students examine rock strata for the distribution, deposition, and age of sedimentary rock. They describe rock types in a variety of outcrops and construct a regional stratigraphy.
Curated OER
Relative Dating In Archeology
Learners generate a time line, interpreting the ways in which past peoples may have used the artifacts at their disposal. Students also develop a poster showing a theoretical stratigraphic deposit, and then analyze the cultural materials...
