This book is designed to provide parents and other adult companions with activities to do with children on outdoor walks. The activities offer adults and children a shared learning experience and have been adapted from the children's education program at Habitat Institute for the Environment (Massachusetts). The activities are arranged seasonally, based on natural history events that can be observed during those particular seasons. Eight distinctly different seasons can be observed: late winter's quiet giants (trees in February and early March), subtle signs of early spring (late March and April), spring's dramatic changes (May and June), long days and warm nights of summer (July and August), summer's grand finale (September), forests in autumn (October), late autumn preparing for winter (November and early December), and snow (mid-December and January). Each seasonal section includes nature study activities that have a reasonably good chance of being done with success in that season. Within the seasonal sections, the activities are presented in random order. (JRH)
