Soil Permeability

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. 

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

Test your class on earth science with this extensive resource. This test, created by The University of the State of New York Regents, is made up of 50 multiple choice questions and 32 short answer questions that cover the branches of...

Covering both permeability and porosity, scholars perform a hands-on experiment testing various soil types. The material includes a pre-lesson worksheet to help focus pupils on the task at hand. 

To use or not use virtual particles—how will your class decide? An episode of the Veritasium playlist explains the controversy of using virtual particles. Although referencing particles seem useful, their behavior is much different than...

Cell membranes and the factors that affect its integrity are studied, with Beet tissue used as the model. A poster to display findings of the permeability of the membranes would clarify understanding and also allow a layer of language...

Some scientists spend their entire careers analyzing and learning about soils. An interesting video lesson provides an overview of what soil scientists do and why. Pupils learn how soil analysis connects to other branches of science and...

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...

Breathe some new life into charcoal. Scholars use biochar to improve soil fertility. They test the effectiveness of this addition by conducting an experiment with soil having 0%, 2%, and 4% biochar.
