This booklet provides background information and five experiments which focus on how energy is lost. Section I contains two experiments to help students discover how energy is lost in their homes. These experiments involve determining a home's location and the weather forces acting on it and completing a home energy audit. Section II contains two…

Presented are 10 science energy education units designed to help students learn how to turn science questions and problems about energy into experiments. Each unit focuses on subject-matter knowledge and on the logic and strategy of scientific problem solving. These teacher-oriented materials include an overview of each unit, background…

A class for adolescent girls of foreign origin was begun in September 1969 at the Vauban "College D'Enseignement Secondaire" (Secondary Teaching College) in Strasbourg. The class became co-educational at the beginning of the 1972-73 academic year. Emphasis is on acquisition of basic French for the purpose of adaptation to the working…

A laboratory summer workshop in materials engineering for high school seniors is discussed. Held at North Carolina State University, the workshop is designed to enlighten university-bound, science-oriented high school students to materials science and engineering, and to construct communication links with high school faculty. The workshop…

The relative effectiveness of including behavioral objectives, classified according to the major levels of cognition, in independent study materials for high school juniors is analyzed in this brief summary of the author's dissertation. The three major questions under consideration are whether: (1) the use of behavioral objectives has an effect…
