This instructor's manual presents lesson plans for a unit of mathematics within the Biomedical Interdisciplinary Curriculum Project (BICP), a two-year interdisciplinary precollege curriculum aimed at preparing high school students for entry into college and vocational programs leading to a career in the health field. Lessons concentrate on biomedical applications in the mathematical area of quadratics, relating mathematical concepts to chemical concepts of pH, scientific notation, molarity, equilibrium and solubility, dissociation constants, and chemical equilibrium. Designed to accompany the student text, lesson plans include objectives, recommended teaching time, and remarks. Keys to problem sets are also included. (CS)
