　　Our goal is to offer timely items of interest to kids, accompanied by suggestions for hands on activities, books, articles, Web resources, and other useful materials.

　　Our emphasis is on making the Web site attractive by offering kids opportunities to comment on and grade the subject matter, get ideas for science projects, and try out math puzzles. At the same time, we offer teachers creative ways of using science news in their classrooms.

　　The Science News for Kids Web site, supported by several corporations and foundations, strengthens the usefulness of Science News in the middle－school classroom and offers entertaining reading and activities for students interested in science.

A section of the Science News for Kids Web site is devoted to particular interests. At present, we have six such zones: a weekly brainteaser(难题) for those who enjoy solving and inventing puzzles (PuzzleZone ), entertaining science－fiction composition exercises for those interested in writing (SciFiZone), and weekly science short description along with science project ideas and tips (ScienceFairZone). The GameZone contains a small selection of logic and memory games. The TeacherZone has materials, including question sheets related to the feature article of the week, so that teachers can bring science news topics to the classroom. The LabZone features a weekly hands on activity or science project idea. In the future, we might add additional zones, for example, for kids interested in robotics, the environment,
