A busy Earth Day celebration is planned for children and adults from 10 a.m. to 1 p.m. Saturday at Elachee Nature Science Center.

The experienced nature education staff and volunteers will provide a variety of fun and engaging educational activities for children, including live animal programs, woodland hikes, arts and crafts and face painting.

While the children are engaged in playful learning, adults may attend a series of backyard conservation workshops from experts including:

“Green Roofs and Rainwater Harvesting” — Julie Evans of the Fockele Garden Company

“The Basics of Effective Tree Planting” — arborist Odis Sisk of Global Tree Preservation

“Backyard Composting” — Peter Gordon of Elachee Nature Science Center

“Energy Conservation in the Home” — Tim Bala, Lanier Technical College

Plus, guests may tour the new “E-House,” an energy-efficient demonstration home, complete with solar panels, a “Solatube” skylight, sustainable building components that save energy and money, and xeriscaping, which is a special type of landscaping reducing or eliminating the need for supplemental water from irrigation.

While Elachee celebrates with its specified activities, the Gwinnett Environmental and Heritage Center will mark Earth Day with activities from 10 a.m. to 3 p.m. Saturday in Buford.

Visitors will enjoy a wide range of activities, including games, guided nature hikes, crafts, solar T-shirt screening, face painting, organic popcorn and much more. Visitors may meet a real life great horned owl at an 11 a.m. presentation and discover the types of wildlife in their own backyard.

Visitors also will have the opportunity to experience “Peanuts ... Naturally,” a traveling exhibit taking a light-hearted look at Charles Schulz’s exploration of the natural world through Peanuts comic strips, videos, objects and interactive stations. Guests get a Peanuts-eye view of the universe, “web of nature,” trees, birds, the elements (snow, wind, rain, and clouds), gardening and Charlie Brown’s EPA escapade. Scientifically oriented interactive stations allow children of all ages to learn more about and appreciate the wonders of the natural world.

The program costs $5 for ages 13 and older and $3 for ages 12 and younger. Children ages 2 and under and GEHC members are admitted free.
