Feature: Earth Day 2012
Posted on April 2nd, 2012 by Mary Lord
For more than four decades, people around the world have celebrated Earth Day on April 22. This year’s organizers hope to mobilize 1 billion individuals to raise awareness about environmental issues and sustainability. Already, some 815 million have pledged to reuse water bottles, organize events, and perform other “Acts of Green.”

Here’s a quick, fun video guide to environmental engineering produced by Channel One News. It explores the California Academy of Sciences in San Francisco and the museum’s signature fully planted roof. It also explains the engineering behind the temperature control system in the four-story interior rain forest and includes an interview with an environmental engineer and advice on how to prepare for a career like his. 
In this service-learning activity, teams of students in grades 10-12 learn the basic principles of fluid dynamics by designing and testing a prototype system to pipe water from a storage tank to a Tippy Tap hand-washing station similar to inexpensive homemade devices used extensively in the developing world.
In this activity, teams of kids in grades 4-7 follow the engineering design process to invent a holder for six cans that’s animal-safe, sturdy, convenient, and easy to carry. They learn why discarded plastic rings can be a problem for wildlife and brainstorm animal-friendly ways to package six cans. They then build, test, and redesign their system and discuss what happened.
In this lesson, students in grades 6-8 discover how engineers can use biomimicry to enhance their designs. They learn how careful observation of nature — in this case, reverse engineering a flower — can lead to new innovations and products. 
An ethanol-powered electric vehicle that can travel the equivalent of 81.9 miles per gallon clinched the EcoCAR Challenge for a team of Virginia Tech engineering students. They beat 15 other student teams in the three-year competition, sponsored by the U.S. Department of Energy and General Motors, to design a more fuel-efficient, environmentally friendly car with the same consumer appeal and safety as today’s models.
The Environmental Protection Agency has a collection of materials that can be used to teach environmental topics like conservation, human health, stewardship, waste & recycling, and water. The EPA also offers publications, awards and grants, workshops, conferences, student scholarships, community service projects, and a club for kids.
Student teams in grades 9-11 gain a better understanding of heat transfer and engineering by designing and building solar water-heating devices that mimic those used in residences. Once the model devices are constructed, students perform efficiency calculations and compare designs.
