Four units focusing on 16 different Black scientists or inventors who have contributed to American life and research are presented. As part of an interdisciplinary high school science course, the units are designed to help students develop an understanding of and appreciation for the talents of the individuals studied, motivate minority students to develop a positive self image, and help all students grasp an appreciation for these undiscovered geniuses. Each unit provides a brief biographical sketch of the four people to be studied, a drawing of each of their faces, suggestions for student and teacher activities, and evaluation procedures. Activities include role playing, simulations, interviews, field trips, research, and individual and group work. A bibliography is provided. (DC)
