Poster and essay contests are widely-used avenues to engage students in environmental activism, but are often solitary activities that involve individual students.

For those teachers looking for something more hands-on, opportunities beyond the traditional poster contests challenge teachers and students to design creative solutions to environmental problems. Students benefit by having a structured setting to think critically and creatively, problem solve, and work cooperatively (not to mention the possibility of extrinsic reward for winning!) Sponsoring groups benefit by finding young talent and creative solutions that may be marketable and beneficial to both businesses, non-profits, and communities.

The Lifecycle Building Challenge, sponsored by multiple groups, including the EPA, Green Building Blocks, and the American Institute of Architects, challenges professionals and students to create buildings, building services, and/or building components that promote materials reuse throughout the entire lifecycle of a building, from design to deconstruction.

By creating buildings that are able to be reused or whose components are built with minimal material waste, contestants will design solutions that reduce the large environmental impact that comes from building and design. Students can enter in three categories: building, component, and service, and the top designs from each category can win multiple prizes, including $2500.

Canon's Envirothon is an annual competition in which students compete for scholarships by demonstrating their knowledge of environmental science and natural resource management. Student team are tested in multiple subjects and present orally in order to determine winners. One of the most extensive contests, there are numerous local and state Envirothons in which student groups can participate, with winners advancing to the national competition.

Finally, hip-hop band The Roots and non-profit Global Inheritance are teaming up to sponsor Feed Your Roots, a student contest to promote composting in schools. Student groups create a program that involves composting and design a poster with information for schools about composting. Winning schools will receive specially-designed compost bins autographed by The Roots themselves.

Contests such as these are interesting and atypical ways to move students from thinking into doing, and hands-on problem-solving allows them to create authentic solutions and make real change in the schools and communities.

Children today have a disconnect as to where their food comes from. For many kids, their favorite food comes from a drive-through. Because our food travels so many miles, and often hardly resembles the actual plants and/or animals from which it came, it's no wonder that kids have no concept of agriculture, let alone the environmental impacts of industrial agriculture.

However, programs that bring gardening to schools are launching all over the country. Children of all ages are making a connection between what they eat and where it comes from, teaching them about ecological principals, fostering environmental stewardship, exposing them to fresh fruits and vegetables, and encouraging them to eat lower on the food chain.

The Edible Schoolyard at Martin Luther King, Jr. Middle School in Berkeley, California, is one of the pioneer programs of school gardening. Founded in 1994 by school faculty and renowned chef Alice Waters, students in grades 6-8 are involved in every stage of gardening, and the garden is seamlessly integrated into the curriculum across disciplines.

At the Maplewood-Richmond Heights Early Childhood Center in Maplewood, Missouri, preschoolers are participating in a program called "Seed to Table", part of the school's Reggio Emilia approach to education. Students help prepare garden beds, plant seeds, tend crops, harvest produce, and prepare the food into meals they eat in their child-sized kitchen. "The children love the school garden and want to help in every way. They are so enthusiastic and capable," said Debi Gibson, nutritionist at the school. "We planted a flower, herb, and vegetable garden this year, including carrots, peas, eggplants, cabbage, lettuce, tomatoes, broccoli, and squash." The students also practice composting, completing the cycle of food.

Programs such as these help students realize at a young age that good food is simple, and comes from the earth that we all have a responsibility to nurture and protect. For more information, check out The Edible Schoolyard's resource site or KidsGardening.org.
