Organic Matter in Soils

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. 

Fourth and fifth graders explore soil by taking a simulated field trip under the earth. They go to an Internet site that runs a simulation which charges them with finding a source of pollution that could destroy all of Earth's soil, and...

Students 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 the art...

In this field investigation, students compare various soil samples taken from specific locations. Students compare samples, record data, create a chart or graph, and keep records in a journal.

Tenth graders collect and analyze soil samples and extrapolate the characteristics needed to support different types of plant life. They research different types of prairie soil and how it supports plant and animal life.

These twenty various types of questions related to the cycling of matter and energy require students to match each definition in column 1 with the correct vocabulary term from column 2. Then, students explain what is being demonstrated...

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...

Learners conduct a scientific investigation about organic or inorganic waste.  In this organic or inorganic waste instructional activity, students create a compost heap to determine the difference between inorganic and organic waste....

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...

Soil pollution has a longer reach than may seem possible. A video presentation demonstrates how a seemingly isolated soil contamination spreads and even reaches waterways. The lesson demonstrates how scientists conduct porosity tests...
