Optional Laboratory: Soil Particle Size and Texture

Earth science learners experiment with the water-holding properties of sand, pebbles, and clay. They apply their findings to the building of a well. This activity is engaging and tactile, and it demonstrates the importance of considering...

Students 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...

Students 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.

Here is a thorough exercise in forming hypotheses for scientific investigations. Young scientists consider factors that may be related to the question they would like to address. They think through measurable changes that may result from...

Using an auger, start-up soil scientists bore a core of soil. They examine the sample and record the temperature at three depths in the borehole. This is an attractive activity sheet that succinctly guides your earth science class...

Worms are the kings of the decomposers. A four-part lesson has learners experiment with the characteristics of earthworms and their sensitivities. They vary factors such as light, acidity, temperature, and touch of soil and observe the...

Learners study the different soil types and describe the different soils in various environments.  In this soil lesson students walk to a reserve and discuss what they saw. 

From types of rocks to types of weathering, learners gain knowledge on minerals, composition of soil, and the effects of weathering on Earth.

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...

In this guided inquiry learners will specify soil types by using various methods of determining soil textures and analyze them with a soil triangle. This activity is a laboratory investigation where students gather data on soil textures,...
