This chapter presents the ideals and spirit of Paul F-Brandwein. In particular, it brings contemporary ideas to themes that he presented almost 50 years ago. Those themes include the substance of science education, curricular structure, and the style of science teaching that emphasized inquiry as a fundamental aspect of science. Two of Brandwein’s essays—“Elements in a Strategy for Teaching Science in the Elementary School” and “Substance, Structure, and Style in the Teaching of Science”—are the basis for the chapter. Consistent with these essays, this chapter emphasizes elementary school science as a focus, and honors Brandwein’s lifelong interest in the environment and conservation by using examples from the environmental sciences.
