One of the greatest results of the increased popular interests in science has been the development of advanced high school science courses. These courses have necessitated the reexamination of junior high school science curricula. In line with this reconsideration the University High School of the State University of Iowa has developed a special junior high school science sequence to aid in this preparation. The seventh grade science course is entitled Matter and serves as the foundation where basic concepts are learned. Those chemical concepts most effectively learned by this age group are: (1) the nature of matter (2) atomic theory and structure (3) periodicity of elements and the periodic chart (4) molecular theory (5) chemical bonding (6) valence and formula writing (7) ionization in solutions (8) concentrations of solutions (9) nature of acids, bases, and salts (10) elementary organic chemistry concepts. Preliminary findings portend the success of this program.
