Free-choice learning and, derivatively, free-choice environmental learning emerges as a powerful vehicle for supporting diversity in learning styles (Falk & Dierking, 2002). In this article, I argue that free-choice environmental learning holds great potential for enabling us to understand what is at stake in environmental learning and thus help us build a sustainable future. I examine the different informal learning contexts for children, home (family and play), museums, zoos, nature parks and wilderness, among many others, and offer an explanation for how learning occurs in these settings
The North Carolina Museum of Life and Science will develop two areas in a new 70 acre outdoor exhibit "BioQuest Woods: Linking Animals and Plans with Interactive Exhibits". This concept is to pair live animals and plants in their natural setting with science center-style interactive exhibits to communicate key ideas in biology and physics. Support will go to sixteen interactive stations in two four-acre theme areas "Catch the Wind" and "Down to Earth". "Catch the Wind" will assist visitors in the exploration air movement and learning about how plants and animals use air in specialized ways. For example, visitors will experiment with air thermals while observing the behavior of birds of prey and will learn how prairie dogs exploit the venturi effect to ventilate their burrows. In the "Down to Earth" thematic area, visitors, simulate the activities of field biologists, will track bears equipped with radio collars, examine living invertebrates, among other activities. Scientific instruments, including microscopes, in kiosks will aid on-the-scene study of live animals and plans. "BioQuest Woods" will help visitors, teachers and students gain the realistic experience of scientific inquiry in a natural setting. Education programming will highlight curriculum linkages and fulfills the goals of North Carolina's new science curriculum. It directly addresses the State's competency-based goals requiring understanding of natural systems and the interrelations of the basic sciences. Pre and post-visit materials will be developed along with teacher guides and enhancement activities. This project is being developed with the cooperation of the Austin Nature Center, the National Zoo, and the Indianapolis Zoo.
The Garfield Park Conservatory will develop, install and evaluate "Sugar from the Sun," a living plant exhibition that explores the fundamental biological process of photosynthesis. The exhibit addresses common misunderstandings and misconceptions about photosynthesis by engaging children and adults in activities that explore the primary concepts that plants require air, water and light to produce sugar, and that the sun is the energy source. The exhibit will be constructed in the Conservatory's Sweet House, where tropical plants such as mangos and bananas will provide the stimulus to engage visitors in learning how plants manufacture sugar from the sun. Exhibits convey the science of photosynthesis and inspire appreciation for the critical role plants play in sustaining life on earth. Supplementary educational materials (self-guides, exploration backpacks and an interactive website) will be layered into the visitor experience, enabling visitors to develop a deeper understanding of photosynthesis. The project also will develop a non-exhibit based model dissemination package for teaching photosynthesis in other conservatories, promoting active science learning about photosynthesis nationwide.
