Soil Permeability & Texture

Earth science learners experiment with the water-holding properties of sand, pebbles, and clay. They apply their findings to the building of a well. This activity is engaging and tactile, and it demonstrates the importance of considering...

Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

Ready to roll up those sleeves and get your hands dirty? Dirty with soil science content, that is! Overcome those "But it's just dirt" objections with a trip outside to collect soil samples for some in-class analysis. Use the variety of...

Drawings of four groups of soil particles of varying sizes are displayed across the page for soil scientists to examine. As they complete the worksheet, place a set of similar soils at each table for hands-on experience. In this way,...

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?

From types of rocks to types of weathering, learners gain knowledge on minerals, composition of soil, and the effects of weathering on Earth.

Teach your class the descriptive characteristics of soil. Provide information about particle size and a flow chart for assessing texture. Soil scientists then analyze samples and hypothesize which would be the best type for a rain...

Seven superb slides sharpen science students' scoop on soil. In viewing them and reading the accompanying captions, your class will uncover the importance, different types, horizons, and protection of soil. They can then assess their new...

Young scholars 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...
