BIG IDEAS

Soil is often referred to as dirt; however, it is a complex combination of organic and inorganic materials.

UNDERSTANDING THE STANDARD

  • Soil is composed of different components that have specific properties that support organisms within an ecosystem.
  • Soil is important because it provides support, nutrients, and a habitat for organisms.
  • Nutrients are materials that plants and animals need to live and grow.
  • Rock, clay, silt, sand, humus, air and water are components of soil.
  • Soil is important because many plants grow in soil, and it provides support and nutrients for the plants.

ESSENTIALS

Essential Questions:

·  How is soil important?

·  What is soil made of?

· How do different types of soil affect plant growth?

In order to meet this standard, it is expected that students will

  • observe and recognize that soil, as a natural resource, provides the support and nutrients necessary for plant growth.
  • analyze and describe the different components of soil, including rock fragments, rock, clay, silt, sand, humus, air and water.
  • design an investigation to compare how different types of soil affect plant growth. This includes organizing data in tables and constructing simple graphs.
