"Nature in the City" is a program designed to introduce young city dwellers to the wealth of nature that thrives in their urban world. The goal is not to produce botanists or zoologists, but to build attitudes and values as children increase their awareness, understanding, and appreciation of nature. Although the natural communities within cities have been drastically altered and reduced by man's activities, a "vacant" lot contains essentially the same lessons as a pristine wilderness area. The "Adventure Guide" is a series of activities, many of them game-oriented, designed to heighten awareness of the natural world. Although written with third- to fifth-graders in mind, it can be easily adapted to any age group. The 17 activity units ("Adventures") may be carried out on any uncared-for spot of land within walking distance of a school. Specific instructional objectives for each Adventure are listed as "Missions" at the beginning of each unit. Unlisted, however, are the interdisciplinary goals that appear in almost every Adventure (for example, vocabulary development). Included at the end of the guide is a crossword puzzle, vocabulary games, and laminated Nature-in-the-City cards with facts and questions about mammals, birds, invertebrates, and plants in a location during each of the four seasons.
