Connecticut's Beardsley Zoo celebrates Earth Day with a weekend environmental extravaganza from 11 a.m. to 3 p.m. The Zoo kicks off the weekend celebration at 11 a.m. on Saturday with a presentation by environmentalist Colin Bennett of Clean Water Action in Hartford, who discusses "Climate Change and its Effects on Wildlife." There is also an Earth Day storytime and craft session for children while parents watch the presentation. From noon to 3 p.m., Zoo visitors can enjoy a variety of earth-friendly activities and presentations, including an alternative energy display with working wind turbine, solar cell and fuel cell. Children can make environmentally- friendly crafts and learn about being a "green" kid during storytime. Earth-friendly vendors offer a great variety of "green" products. More events take place on Sunday from 11 AM to 3 PM, including a Backyard Scavenger Hunt for kids.
