Introduced Species

by NSTA Staff, Brad Williamson, Margaret Edwards, et al.

Critical issues about the impact of human activities on ecological systems challenge tomorrow's generation. This series introduces students to the science behind the headlines. Each volume in the Global Environmental Change series targets an essential issue and involves students in research and discussion to teach concepts and decision-making skills.Human activity has introduced species to ecosystems around the globe. Some species are benign or even beneficial; others, like zebra mussels, fire ants, and water hyacinths, are causing native-species extinctions and damage to human systems. Can we balance human systems with natural processes? Seven activities -- using pillbugs, the school grounds, species dispersal maps, and introductory genetics -- provide students with the skills they need to address this important global question.
