Dirt and Soil

Introduction: Our next unit in Science focuses on the earth’s soil. We will look at websites that help us determine the different layers of soil, their characteristics, and what substances can be found there. Soil is not just what we step on; there are many elements that make up the earth’s surface that have different textures, colors, and particles

Visit the Discovery School website and read the information and answer the questions below:

1. List the various layers of soil and 3 characteristics of each.

2. Explain the difference between dirt and soil

Then, double click on the Name that Soil button on the left hand side. This takes you to another page that lists characteristics of gravel, silt, sand, and clay.

Using information you have gathered, determine…

1. What soil is best for plants to grow? Which soil is not good for

plant growth? Why?

2. What elements of soil need to be present for the plants to thrive (clay, gravel, silt, or sand)?

3. What layer of soil would have the most silt? Clay?
