2.   What are the differences between dirt and soil?  Dirt is what you find under your fingernails. Soil is what you find under your feet.  Think of soil as a thin living skin that covers the land. It goes down into the ground just a short way. Even the most fertile topsoil is only a foot or so deep. Soil is more than rock particles. It includes all the living things and the materials they make or change. Engage

3.   Ground Level:  Topsoil:  Subsoil:  Weathered Parent Material:  Bedrock: Explore

4.   Core Sampling is a cylindrical section of a naturally occurring substance. Most core samples are obtained by drilling with special drills into the substance, (for example sediment or rock), with a hollow steel tube called a core drill. Explore

5.  Explain Topsoil Subsoil Parent Material Bedrock Draw a line from the soil to the correct container.

6.   There are 12 different types of soil.  Soil orders reflect the environment which the soil is in. Elaborate

7.   Use your knowledge of soil to match the vocabulary terms to the right definition. Evaluate

8.  Drag materials to the beaker in order. Evaluate clay Organic matter silt water sand

9.   Today we talked about soil and materials with in the soil, who can tell us the types of soil?  We must all do our part to help conserve soil. Here are some ways to help conserve the soil. End

11.  Content Objective- The student will: o oIdentify different types of materials in soil. o oInvestigate the found particles in the soil sample. o oRecord their observations during the investigation.  Process Objectives- Observing, Measuring, Sorting and Classifying, Communicating. o oPredict what soil is made up of and how to found out what is in the soil (Predicting). o oObserve the various types of soil particles (Observe). o oRecord their observations and share with the class (Communicate).  Background knowledge needed- Students need knowledge of soil. o oThe students should be familiar with the different soil particles. They should have a knowledge of dispersion and osmoses; the flow of material when placed in water.  NCTM standards o oD. Earth and Space Science - Earth and space science focuses on science facts, concepts, principles, theories, and models that are important for all students to know, understand, and use. M.D.1 Structure of the earth system: e. Soil consists of weathered rocks and decomposed organic material from dead plants, animals, and bacteria. Soils are often found in layers, with each having a different chemical composition and texture. Teacher Page

16.   oSoil is composed of many different types of elements such as; sand, silt, clay, and organic matter. When soil is submerged in water these elements combined together. By placing the chemical alum in the mixture, these elements disperse depending on each elements density. The elements most dense will settle to the bottom and the elements lease dense will be found on the top. Summary of Content Knowledge
