Overview

Students review ideas covered in the Global Atmospheric Change unit, write persuasive letters, and revise their pre-assessments, as needed. Student sheets are provided in English and in Spanish.

This activity is from The Science of Global Atmospheric Change Teacher's Guide. Although it is most appropriate for use with students in grades 3-5, the lessons are easily adaptable for other grade levels. The guide also is available in print format.


Teacher Background

For more than 100 years, human actions have been changing the composition of Earth’s atmosphere. Increases in the levels of heat-trapping greenhouse gases (especially carbon dioxide) and decreases in the amounts of stratospheric ozone both have been measured. These processes have the potential to impact humans in many ways.

This activity is designed to assess student understanding of concepts related to global atmospheric change. Each student will write a persuasive letter about a topic related to protecting the atmosphere.

Objectives and Standards

Concepts

  • Students are able to improve their own health and that of the planet.


Science, Health and Math Skills

  • Comparing

  • Identifying relationships

  • Inferring

  • Applying prior knowledge to new situations

Materials and Setup

Materials per Group of Students

  • Crayons or markers

  • Drawing paper

  • Pencils or pens

Materials per Student

  • Copy of his or her pre-assessment


Setup

Begin with a whole-class discussion, after which students will work individually.

Procedure and Extensions

  1. Tell students that they will write persuasive letters to each other related to global atmospheric change. Introduce letter writing skills if needed. Mention that global atmospheric change is a broad category that includes global warming and loss of atmospheric ozone. Also mention that all of us do things every day that contribute to these problems. Each student should try to convince the reader to help protect the atmosphere by changing behaviors to reduce the possibility or impact of global warming or ozone depletion.

  2. Review the importance of our global environment to individual health and to the health of the planet. You may use the “Tips for Healthy Living” on page 3 of the Global Atmospheric Change unit's Explorations magazine, or pages 34–35 in the storybook, Mr. Slaptail’s Curious Contraption, or a review of the activities in this unit to guide students.

  3. Each student should select one issue presented in this unit and write a letter to try to convince someone to help protect the atmosphere.

  4. Distribute pre-assessments back to each student. Ask students to examine their answers and, using a different color, to circle new answers based on information they have learned.

  5. Discuss students’ changes as a group.
