How Sedimentary Rocks are Formed

Turn your class discussion of rock formation from ho-hum to holy hornfels! Junior geologists gain experience in identifying rock types and rock origins, with an emphasis in hypothesizing the environment needed to form certain...

After five class sessions, young scientists will be able to identify common rock types: igneous, sedimentary, and metamorphic. This plan involves hands-on activities, includes various handouts and worksheets, and requires there to be...

You don't have to travel far to learn about rocks, just step outside, pick up a stone, and begin investigating. After taking a class walk around the school grounds collecting rocks, young scientists practice their skills of observation...

Take young geologists on an exploration of the rock cycle with this six-lesson earth science unit on rocks and minerals. Through a series of discussions, demonstrations, and hands-on investigations your class will learn...

Time to rock out! Discover the "life" cycle of the average rock using an illustrative stations lab and stimulating pairs game. Roll the dice to determine your fate: will it be melting in magma or chilling out to form igneous rock? The...

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....

Fascinating photos of sedimentary rocks and formations supply a brief overview for your geology class. By viewing these slides, learners discover that sedimentary rocks are made of tiny bits of rock, dirt, or shell that have settled,...

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.

This video, meant for older students, clearly explains how each of the three types of rocks on the earth's surface are formed. I learned that 75% of the earth's land area is made up of sedimentary rocks! Interesting details about the...

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...
