You want me to do what with this Dirt?

Using an auger, start-up soil scientists bore a core of soil. They examine the sample and record the temperature at three depths in the borehole. This is an attractive activity sheet that succinctly guides your earth science class...

Simulate soil sample assemblages. Individuals create soil layers in a cup. They then use straws to collect core samples from these layers. What information can they glean from the core samples, I wonder?

Students list sources of phosphorus in soil. They explain how phosphorus is removed from the soil and used by plants. Students list the symptoms of insufficient or excess phosphorus. Students perform experiments to examine the effect of...

Students investigate soil temperatures. In this graphing and earth science lesson, students insert temperature probes into different types of soil at varying depths. Students complete a data chart and construct a related graph...

Help your class come up with a procedure for comparing the dissolving rates of colored candy coating in different temperatures of water. If you are placing importance on controlled variables with your class, make sure that they use equal...

"God made dirt, so dirt don't hurt!" In fact, dirt is soil, which is an amazingly dynamic material that we cannot live without! Dig into the depths of soil development, topography, and layers with this PowerPoint. The photos are fuzzy,...

Your geology class practices taking core samples of a potato to examine the stratigraphy. This is a terrific modeling lesson that helps youngsters visualize strata that cannot be seen from the surface of the ground. The directions...

Students sample goodies from an unseen ocean floor and try to accurately describe their composition. This simulation helps students explain the limitations of sampling and the problem of obtaining representative samples of sea floor...

Students examine how to take the impurities out of eater.  In this exploratory lesson students complete an experiment on how to filter drinking water.
