Curated OER
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....
Curated OER
Layers of Rock
Juvenile geologists drill clear plastic straws down into a playdough sedimentary rock model, pulling out sample rock cores. As they analyze their cores, they apply the law of superposition and discover that originally horizontal layers...

Fossils and The Law of Superposition
In this fossils and the Law of Superposition worksheet, students fill in 4 blanks with the proper terms that match definitions about fossils and rock layers. They complete 9 questions about 2 activities they performed related to the age...

Who Was Here First? Relative Dating
Students read about and complete question activities for the topic of relative dating. In this relative dating lesson, students read information for the topic and then complete two activities to further their understanding of geologic...
Curated OER
Law of Superposition
Students define relative dating and describe the law of superposition. They apply their knowledge to construct an accurate geologic time scale. Students examine the importance and function of biotechnology in Earth Science.

Earth's History
Seventh graders study the law of superposition by creating models of fossils in layers of rock. They examine how fossils are usually found in sedimentary rock which leads to the study of geologic history in those rocks.
