Using Soil properties and Vegetation Differences to Hypothesize the Land Use History and Topographic Differences between Two Locations

Class members analyze the water content in soil samples by drying out the samples and taking measurements every minute until all the moisture is gone. Scholars compare the initial weight to the dried weight to calculate the percentage of...

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture. 

Not all soil is created equal. Learners examine what to look for in a soil sample to identify key characteristics that don't require lab testing. They see that it's easy to verify observations by comparing the samples to a soil map.

Taking a sample of soil requires more than just a shovel and bucket. Viewers learn about the important factors to consider when taking a soil sample in an informative video presentation. The narrator demonstrates the process in an actual...

You won't find any holes here. An earth scientist demonstrates the process of collecting a soil sample in a quick video presentation. She uses two different tools and discusses the benefits of each.

Soil is 25 percent air on average. Learners may have a difficult time accepting that fact without a visual to demonstrate the property. A quick video lesson uses a model to show how this percentage is true and also discusses the...

Add a little salt to your soil and see what happens. A video demonstration shows how soil with high and low sodium content interacts with water. A quick experiment demonstrates the properties of dispersion and the role sodium has in the...

This description of this activity is a 2-day lesson: Day 1, Field Lab, Day 2, and Classroom Investigation. In this field lab, children working in groups will collect 3 samples of soil from different locations. Each sample will be placed...

A field based lab experiment where students work in groups to come up with a collection strategy and lab analysis to test differences in soil bulk densities. Students bring soil samples back to the classroom to conduct a test that...

The North Carolina Department of Agriculture explains soil testing, taking a soil sample, and analyzing the results.
