There's still plenty of time to enter "Get to Know Your Wild Neighbors," a nationwide creativity contest for youths in which the East Bay Regional Park District is participating.

Canadian artist and naturalist Robert Bateman created the Get to Know Program as a way of encouraging stronger connections between young people and nature.

The idea is for youths ages 19 and younger to get outdoors, enjoy the world of plants and animals and then submit art, writing, video, photography or music inspired by the experience. Entries should be about nature; pets and farm animals are not eligible subjects.

Entries can be submitted online at www.GetToKnow.org. There's no entry fee, and you may enter as many times as you like. The contest runs through Nov. 1. Winners receive prizes such as art supplies, cameras, camcorders, books, outdoor gear and more.

For teachers and community organizations the GetToKnow website has lots of resources, lesson plans and activity guides designed to complement science and art curricula at all grade levels.

For more information on the contest you can also visit the park district website, www.ebparks.org and click on the Get To Know Contest icon on the right side of the home page.
