Air pollution is all around us, even in the North and South Poles. Air pollution comes from natural (volcanoes, forest fires) and manmade factors (automobiles, factories). This chapter book offers young readers basic reference information on what causes air pollution, how it affects human health, and the environment, plus what can be done to prevent and clean up air pollution. Each page highlights a new topic which is supported with bright, colorful pictures. New vocabulary words are highlighted throughout the text. There is even a discussion on careers dealing with air pollution. One simple experiment demonstrates a method to test for air pollution. This experiment uses simple household materials and can be completed in the classroom or at home. At the end of the book, there are additional references to study air pollution. The final section offers inquiry questions with answers, and "Words to Know" to reinforce new vocabulary words. This book is in the "Science Matters" series. It highlights interesting information to supplement beginning book reports, and is satisfactory for high-low readers.
