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.

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 name three general kinds of soil: sand, silt and clay. They explain how percolation rates differ with the soil type. Students name two characteristics of wetland soils. They test soils to demonstrate how soil texture affects...

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.

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...

Students examine that all living things depend on soil to live. For 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.

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

Learners 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...

This lesson plan is an investigation of soil properties, particularly texture, color and space for air and water. Student inspect soil samples found in their locale, perform several tests to determine different properties, and involves a...
