The purpose of this project is to help elementary school teachers get started using the computer to aid the teaching and learning of many scientific concepts in a meaningful way. The authors have developed their own software package, "Elementary Science Activities," and have selected several commercially available software packages that are versatile, cost effective, and easy to use. This report includes reviews/descriptions and several activities for these programs. The teacher-developed software contains a "Rock Identification Key"; a "Needle Trees Key"; and "The Solar System." There are program reviews/descriptions for the commercial software "The Factory," and "The Pond"; and reviews/descriptions and activities for "The Incredible Laboratory,""MECC Graph," and "Science Tool Kit, Master Module." The format of these programs pairs readily available manipulatives with computer programs to develop logical thinking skills as they query and guide the student through the activities. The programs were selected to aid the development of logical thinking, pattern recognition, sequencing, and organization. They are self-testing and correcting, and help to promote self-motivation by incorporating fun, graphics, and sound into the lessons. (YP)
