Let's Get Started

In this activity, each student will write a persuasive letter on a topic related to protecting the atmosphere. Students will make comparisons, identify relationships, infer, and apply prior knowledge to new situations.

  1. Review the importance of our global environment to individual and global health. You may use the "Tips for Healthy Living" on page 3 of this unit’s Explorations magazine, or pages 34–35 in Mr. Slaptail’s Curious Contraption, or simply review the activities this unit’s teacher guide. 
  1. Each student should select one issue presented in this unit and write a letter trying to convince someone to help protect the atmosphere and/or slow global atmospheric change. 
  1. Return each student’s pre-assessment and have students examine their original answers. Then, have them use a different color pencil to circle any new answers, based on what they have learned in this unit. Discuss students’ changes as a group.
