Explains what standing rocks are, how they are formed by erosion, and gives the names of some well-known ones in Indiana.

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...

The purpose of this activity is to demonstrate the importance of rocks, soils and minerals in engineering and how using the right material for the right job is important. The students build three different sand castles and test them for...

This interactive website explores the various soil layers and introduces you to the lifeforms that live in those soil layers.

Smithsonian in the Classroom presents Building Up, Breaking Down. Teachers can download this comprehensive teaching package in which students investigate how buildings weather. See what happens to a building once it has been erected....

Young students are introduced to the complex systems of the Earth through numerous lessons on its natural resources, processes, weather, climate and landforms. Key earth science topics include rocks, soils and minerals, water and natural...

After completing this lesson plan, students will understand the source and the process for the formation of soil, the different types of soil, and the components of soil.

Abiotic components are the nonliving components of the biosphere. Chemical and geological factors, such as rocks and minerals, and physical factors, such as temperature and weather, are referred to as abiotic components.
