Much of the innovation in the use of microcomputers in education has come from classroom teachers who are using computers with students. In October, 1987, forums were held for secondary school science teachers who were using computers in their science classes. Within this document are some of the lesson plans that the participating teachers brought to the sessions. The lessons outlined in the booklet include computer applications for: (1) physical science laboratories; (2) stratigraphy; (3) teaching about significant digits; (4) weather forecasting; (5) chemical reaction synthesis; (6) creating a database about tides; (7) science laboratory tools which measure heat, light, and temperature; and (8) a teacher-made program dealing with laboratory calculations. The descriptions contain the name and address of the contributor, the target audience of the lesson, the hardware and software needed, and a brief statement about the purpose and objectives of the lesson. Some of the lessons also include a listing of the computer courseware and some sample student worksheets. (TW)
