Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

In some cities, especially large cities such as Los Angeles or Mexico City, visible air pollution is a major problem, both for human health and the environment. A variety of sources contribute to air pollution, but personal vehicles account for one of the main sources. Though each car has relatively low emissions when compared to vehicles of the 1970s, there are so many more cars on the road now that their emissions play a large role in overall pollution. In this activity, students think about alternate ways to power a vehicle to reduce emissions. Student teams design an eco-friendly car using the engineering design process, and make a presentation to showcase their product.

Students develop their understanding of the effects of invisible air pollutants with a rubber band air test, a bean plant experiment and by exploring engineering roles related to air pollution. In an associated literacy activity, students develop visual literacy and write photograph captions. They learn how images are manipulated for a powerful effect and how a photograph can make the invisible (such as pollutants) visible. Note: You may want to set up the activities for Air Pollution unit, Lessons 2 and 3, simultaneously as they require extended data collection time and can share collection sites.
