Nuffield Secondary Science is a set of tested materials from which teachers can prepare courses for students in grades 9-11 (approximately) who do not intend to major in science. The materials are designed for British secondary schools but are adaptable to other countries. The Teachers' Guide to the entire set of Themes is described in SE 015 440 and the nature of each Theme summarized in SE 015 441. Theme 2 contains the following fields of study (with the subsidiary sections indicated in parentheses): Animal and Plant Reproduction and Propagation (introduction to life cycles, aspects of life cycles, importance to man of knowledge of life cycles); Inheritance (variation in plants and animals, what influences plant growth?, ancestry and variability, why am I like I am?, mechanism of inheritance, how useful is man's knowledge of inheritance?); and the Process of Evolution (evolution of dog and rose breeds, human physical evolution, fossil evidence, variation in populations, variation/adaptation/predation, micro-evolution in action, biogeography, quadruped limb, similarity of man and other animals, human effect on evolution).
