How Are Soils Classified?

It's time to roll up those sleeves and get a little dirty in the second lesson of this series on the science of food. Investigate where plants and animals get the minerals they need to live in this two-part exploration of soil. First,...

What type of soil holds in moisture the best? Find out with a guided-inquiry based lesson in which scholars investigate three types of soil—sand, clay, and silt—and the ability of each to retain waiter for plant growth. Learners graph...

Groups of three scientists from the rocky planet Zog investigate the composition of soil so that they can take the information back to their home, create soil there, and begin to grow food.

You don't have to travel far to learn about rocks, just step outside, pick up a stone, and begin investigating. After taking a class walk around the school grounds collecting rocks, young scientists practice their skills of observation...

Take young geologists on a trip through the rock cycle with this series of four earth science presentations. Beginning with an exploration of minerals and the different properties they exhibit, this resource goes on to explore...

Students, in groups, conduct an experiment to compare how water moves through different soils. They discuss how different soils could have an impact on different plants.

This presentation on soil shows how it is formed, what the different types of soil are, how soil is eroded, and how soil can be conserved. Fantastic photos and excellent graphics and text are found in each of the slides. The last slide...

Digging up a more valuable geology app than this one would be hard to do! This app introduces junior geologists to rocks, minerals, soil, and fossils with informational text, photographs, and videos. Check it out, but don't take it for...

Young scholars list the three texture groups that classify soils. They classify a soil sample as sandy, silty or clay soil.

Students examine that all living things depend on soil to live. In this science lesson, students pretend that an apple is planet Earth. Students cut the apple to represent the portions of Earth with the last section representing soil.
