Here's a chance to get your community's schoolchildren thinking about energy and water conservation.

Johnson Controls and the National Energy Foundation's 10th annual Igniting Creative Energy (ICE) Challenge ? a national competition for kindergarten through 12th grade students to share ideas about wise energy choices and environmental stewardship ? for the first time includes a water efficiency category.

Entries can be science projects, essays, stories, artwork, photography, music, videos, or Web sites that demonstrate creative new ways to use less energy. Students also must write a one-page explanation of how their project relates to the theme "igniting creative energy."

The entry deadline is March 4; winners will be announced in April. Five grand prize trips for two to Washington, D.C., will be awarded to four students and 1 teacher. Winners are also invited to participate in the U.S. Energy Efficiency Forum, which takes place June 15 ? 16 in Washington, D.C. Early bird entries submitted before Feb. 18 are placed in a drawing to win more prizes.
