Each unit emphasizes the Think Earth message while focusing on a specific theme. Preschool focuses on conservation. Children learn how and why to turn off lights, televisions, and water when they are not being used. Children also learn how to recycle newspapers, cans, and bottles, and how to dispose of trash properly so they don't litter. Along with the delightful Think Earth video, flannel-board stories are used to emphasize and practice the environmental messages.
Kindergarten focuses on conserving trees and other resources.
Stories about Jay and his treehouse show students that trees provide us with many benefits, including fresh air, wood, and paper, and students learn the importance of using paper, water, electricity, and other resources wisely. Grade 1 focuses on conserving natural resources. Bernie, the runaway school bus, helps students learn that recycling, along with using water, paper, electricity, and natural gas wisely, are important ways to conserve natural resources. Students discover that everything comes from the environment. Three mischievous Rascals show students that by practicing the 3 R's, they can not only reduce the amount of solid waste that gets buried in landfills, but also conserve natural resources, save energy, and reduce pollution.
