3.4 — Earth materials provide resources for all living things, but these resources are limited and should be conserved.

3.4.a. — Decisions made by individuals can affect the global supply of many resources.

B7: Describe how earth materials can be conserved by reducing the quantities used, and by reusing and recycling materials rather than discarding them.

Prior Knowledge: Students will be familiar with the topic and related terminology covered in prior lessons.

Student Learning Objectives: Students will learn ways they can individually reduce pollution and waste in their communities.


Domestic waste - garbage that is produced by families in their homes

Conservation - protecting natural resources, animals, and their habitats

Recycle - to convert into reusable material

Ecosystem - a biological environment consisting of all of the living organisms living in a particular area

Environment - the natural world

Technological resources: Computer with internet access and web based browser, PowerPoint application, Overhead projector

Learning Activities:

Instructional Strategies: Modeling

Grouping Strategies: Small group presentations

Initiation: To initiate the lesson, review the KWL chart and the vocabulary words. Show PowerPoint of your own on Recycling.

Lesson Procedures:

1. Have students form groups. Arrange this based on classroom size, but groups should not be larger than 5 students.

2. Students will be assigned a pollution issue from the KWL chart. The groups will be responsible for creating a PowerPoint presentation that defines the issue and lists possible solutions. Each student will be responsible for one slide.

3. Students will have library and computer lab time to gather resources to include in their presentations. Media and library specialists will instruct students on how to research their topics and properly gather resources.

4. After students have completed their PowerPoint, each group will present to the class their topics along with their PowerPoint presentations.

Closure:  When each presentation is finished, students can open the floor for discussion, noting what they liked about the presentations or how they may have additional solutions to a groups pollution issue.

Intervention:  Students with special needs and that require accommodations will be given assistance on an individual need basis. Extra time can be given. The teacher or library/media specialist will assist students that need additional help.

Extension:  Students that are able to finish their individual slides early will be expected to assist their group members.
