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...
Curated OER
Layers of the Earth
Third graders examine the layers of the earth during a teacher led discussion. They listen to a read aloud of "How to Dig a Hole to the Other Side of the World," as they "visit" each layer. They work a worksheet while small groups design...

The Mystery of Earth’s History
Every living creature can leave a fossil record, yet most fossils belong to extinct organisms rather than ones currently living. Scholars learn about dating rock layers, fossils, and the environment of the past. Pupils understand that...

Lava Layering
Take the old baking soda and vinegar volcano to the next level by using it to study repeated lava flows over time, examine geologic features on Earth and Mars, and speculate about some of the formations on Mars.
Curated OER
Core
Eighth graders take their own "core sample" with clay and/or play-dough and correlate the layers of the earth.
Curated OER
Structure of the Earth
Eighth graders describe and identify the three layers of the Earth. They work together to construct their own earth model. They share their creation with the class.
Curated OER
Relative Age Dating
Modeling dough and paper cutouts in science class? Learn about how relative age dating concepts, like the Law of Superposition and cross-cutting relationships, can be used to describe the formation of sedimentary layers.
Curated OER
Understanding Lava Layers
Seventh graders trace the lava flow of an erupting volcano. In this earth science lesson, 7th graders experiment using baking soda and vinegar. They record and share their observations.
Curated OER
Franklin Mountains
Fifth graders examine photographs of the eastern and western Franklin Mountains. As a class, they discuss what is shown and the different colored rocks and the orientation of the layers. In groups, they are given clay of two different...
