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,...

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.

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

Study the properties of soil and water absorption with a science activity. Based on a paragraph with background knowledge on sandy soil, silt, and clay soil, third graders choose which illustration represents a bottle full of sandy soil....

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.

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...

Young scholars conduct an experiment to evaluate whether plants need soil to survive and grow. They plant two seeds, one with soil and one without, make predictions, and record and analyze the seed germination results on a worksheet.

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...

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

Students examine the various soils and list the parts of the ecosystems. In groups, they investigate the soils to determine its texture and the permeability rates. They give examples of how soil information is used to determine human...
