Sedimentary Rocks

More of a mini-unit than a lesson, these activities lead inquisitors through a survey of oil deposits. In the first part, they read about and view diagrams of sedimentary rock layers that trap oil. Next, they test porosity and...

Rock out with the second installment of a five-part series on earth materials and processes. Your budding geologists make observations of given rock samples and posit classification systems for rocks. They then learn about the accepted...

Science rocks! Explore three types of rocks and the rock cycle with an igneous rocks experiment. Pupils discuss textures, composition, and learn how melts are formed from the Earth's crust. They weigh materials using a scientific scale...

Sedimentary rocks are the building blocks of this geology lesson. In it, learners discover what sedimentary rocks are and how they form. They understand the differences between the major sedimentary rock varieties and learn what types of...

A timely resource illustrates the effects of the passing years on sedimentary rock formation! Young geologists discover just how long it takes to create shale, slate, and other sedimentary rocks. The interactive also shows...

Students review the three types of rocks and the rock cycle. They participate in an experiment in which they discover the lithification process of sedimentary rocks. They record and share their observations.

A simple activity goes a long way in demonstrating the property of porosity to your rock hounds. They will mass a specimen of dry sandstone and then soak it in a pre-measured amount of water. After seven minutes, they once again measure...

The goal of this fine geology lesson is to have learners create a map that shows how the rock layers are arranged far underground where they can't be seen. The ambitious lesson plan requires high schoolers to learn the law of...

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...

All rocks include two or more minerals but greatly vary in appearance. The online interactive encourages scholars to match the rock types to the facts they know about each. They then complete three grid puzzles reviewing the same...
