Optional Laboratory: Soil Particle Size and 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 worksheet, place a set of similar soils at each table for hands-on experience. In this way,...

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...

Soil scientists gain experience with an infiltrometer can to determine the infiltration rates at different locations on campus. If you are using the entire unit, the class has already analyzed water flow and soil types, so they should...

In this bellwork worksheet, students answer questions about chemical and mechanical weathering, particle size, and the soil profile at the start of class.

Learners are introduced to soil textures and why they are important in examining soil quality. They find out how to feel the difference between soil textures. Pupils describe which soil texture is best for gardens and growing healthy...

Learners show how soil varies across the landscape, they explain how soil can be used to solve mysteries. Pupils are introduced to techniques that would be used to distinguish soils from different places.

Young scholars investigate the use of soil, an important natural resource in artwork. They experiment by crushing soil particles and adding the different color samples to artist acrylic to create true "earth colors". Using this paint,...

Students explore the porosity of soil. In this soil instructional activity, students conduct an experiment which shows the porosity of different types of soil. They use sand, silt, and clay to see how soil particles are more or less...

Students examine the relationship between particle size and rate of water flow through soil. They collect soil samples, make predictions, conduct a water flow experiment, analyze the data, and answer conclusion questions.

Students work together to discover the relationship between water holding and drainage characteristics of soils. They record their observations and discuss the results. They examine particle size and pore sizes as well.
