Density and Texture of Soil

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...

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?

High schoolers explore and experiment with the concept do new kinds of insects appear after soil modification. They assess and review scientific methods of observation, predicting, variables, math skills, ratio, proportions, graphs and...

Students study the basics of soil science. They research and gather data through readings, videos, and performance of laboratory investigations. As a team they generate oral and written recommendations for the amendment of soil.

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.

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.

What defines a random sample? Scholars learn how to collect a random soil sample from a large field. The narrator explains the importance of ensuring the sample is random and shows how to create a random sample before sending it to the lab.

There's some serious science behind farming! A quick video lesson presents the process of collecting a random field soil sample for analysis. Instruction includes what a random sample looks like as well as how to prepare the sample for...

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...

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...
