Use crayons to model the rock cycle in this fun activity! You will make colorful sedimentary, metamorphic, and igneous "rocks" from crayon shavings.

Gain an understanding of the cycles that form metamorphic, sedimentary, and igneous rocks.

This activity combines the concept of Earth's rock cycle with the characteristics of other planets in the solar system.

This is a large collection of resources on cycles of nature and the Earth. There is a constant exchange of the elements between air, earth, water, plants, and animals. Most biological processes wind up back where they started. These...

Explore the differences between minerals and rocks.

Find out how rocks and rock layers change with erosion and weathering.

Did you know the rock cycle is a continuous cycle that takes hundreds of millions of years? This webpage explains how sedimentary, metamorphic, and igneous rocks are formed. It also gives examples of each type of rock. Also includes a...

Rocks cover the earth's surface, including what is below or near human-made structures. With rocks everywhere, breaking rocks can be hazardous and potentially disastrous to people. Students are introduced to three types of material...

To experience the three types of material stress related to rocks - tensional, compressional and shear - students break bars of soap using only their hands. They apply force created by the muscles in their own hands to put pressure on...

In this interactive tutorial you will learn how pressure creates stress and strain on rocks. Learn how different types of strain are produced by different plate tectonic settings, and explore the different types of mountain ranges and...
