Forty-one activities are suggested for middle or junior high school students to perform while visiting a city street. The activities make use of skills in mathematics, language arts, social studies, and environmental studies. A pencil and a copy of this workbook are essential; other materials required by some of the activities are a tape measure, magnet, and tape recorder. The students can work individually or in groups to determine the following types of information about a city block: number of windows in houses, various building materials, length of sidewalk, scientific names of trees and plants, services provided by stores and businesses, noises of different times of the day, and safest or shortest ways from home to school. Creative activities include writing a poem about the smells and sounds of the city block, creating a radio commercial to show certain aspects of the block, interviewing residents, inventing new uses for familiar objects found on the block, and mapping routes from one place to another. The authors recommend that a trip to a city street be arranged like a field trip, and that permission be obtained from school administrators and parents. (AV)
