Presents three activities for teaching elementary students about the built-in mechanisms that help warm-blooded animals maintain constant internal body temperatures. The activities help students understand why humans sweat, why dogs pant, and why blubber keeps whales warm in frigid water. (SM)

Why introduce genetics at primary level? Children are fascinated by themselves and where they come from. Many have heard of genes, mostly through the media coverage of genetics, and want to know more. Children should be engaged in science at an early age to foster an interest and encourage an appreciation of its relevance to life. Genetics sits…

Web-based instruction was integrated into a course on human biology given to prospective elementary school science teachers. The goal of the study was to reveal the students' perceptions about the teacher's roles in such a course. Data were gathered from the teacher's forum and e-mail messages, students' e-mails, and interviews. The findings…

In October 1981, an article appeared in "The American Biology Teacher" with the catchy title, "Bio-Bull."
