Below are a few opportunities to end the summer playing with children and enjoying the Earth.
Morris Arboretum
It's been a year since it was launched, but Out on a Limb at the University of Pennsylvania's arboretum is still going strong, said Susan Crane, director of marketing.
Out on a Limb is a 450-foot-long canopy walk. It is a $3 million attraction, which aims to teach children the importance of trees in today's world, and that lets kids (and adults, too) explore a leafy playground 50 feet above the ground.
The exhibit has several interactive stations, complete with a "passport" that kids can stamp once they have completed an activity at each station.
Morris Arboretum, 100 Northwestern Ave. Hours: 10 a.m. to 4 p.m. weekdays; 10 a.m. to 5 p.m. weekends; on Thursday the arboretum will be open until 8:30 p.m. Admission is $14, $12 for seniors, $7 for students, active military and youths ages 3 to 17, and free for members and children under 3. Information: 215-247-5777.
Tyler Arboretum
Tyler runs hour-long minicamps throughout the summer, and there's still time to sign up for its late August programs, Ney said. The arboretum, which offers camp for up to 50 children each week, has programs for children ages 3 ("Teeny Tiny Trackers") to 9 ("Nature Kids"). This Sunday's class is the last family session this summer, and focuses on monarch butterflies' migration to Mexico. Children and their parents can help "tag" butterflies at Tyler so they can be tracked on their journey south. The class runs from 1:30 to 2:30 p.m., and preregistration is required.
The last "Teeny Tiny Trackers" program this summer, meant for 3-year-olds, is set for Monday from 10 to 11 a.m. and also features a butterfly theme. Children must be accompanied by an adult.
