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...

It takes a minimum of 500 years to form one inch of topsoil. Young scientists conduct multiple observations and experiments on three different types of soil. The activity leads class members to a better understanding of pH, water...

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?

Learners 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. Learners perform experiments to examine the effect of...

"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 the various soils and list the parts of the ecosystems. In groups, they investigate the soils to determine its texture and the permeability rates. They give examples of how soil information is used to determine human...

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