Science/Strand V/Content Standard 1/Elementary
Benchmark 2
Recognize and describe different types of Earth materials.

Benchmark Clarification

The Earth's surface is made of many different materials, such as minerals, rocks, boulders, gravel, sand, clay, and soil.

Students will:

  • Classify many types of materials
  • Recognize and locate where these materials can be found locally

Instructional Example

Benchmark Question: What is the Earth's surface like?

Focus Question: How would you recognize the different natural materials found on the Earth's surface?

The teacher will give students samples of each of the materials found in the Key Concepts

Students will study the samples using various science processes and tools such as a hand lens, balance, and ruler. During their observations, students will discuss questions about rocks, minerals, and soil (including gravel and sand) such as:

  • What does it look like?
  • What does it feel like?
  • How is it like the others?
  • How is it unlike the others?
  • Where would you find this locally or in the state?
  • How would you use it?

Students will record their observations in a data table.

Small groups of students will write their observations using the answers to the questions.

Constructing: (SCI.I.1.E.1), (SCI.I.1.E.2), (SCI.I.1.E.3), (SCI.I.1.E.4).

Reflecting: (SCI.II.1.E.1), (SCI.II.1E.5).

Assessment Example

The teacher will give students Earth materials and a hand lens. Each student will identify the Earth materials by sorting the samples into pre-labeled containers.

(Give students rubric before activity.)
