"Helping students make connections between the functions and processes of an organism’s body systems and its survival is a fundamental concept that all students need to understand," writes Inez Liftig in the Editor's Roundtable in the April/May issue of Science Scope. "Middle level students do not need to be taught complex biochemical reactions or the intricacies of multiple physiological mechanisms, but they do need to see how the maintenance of an internal equilibrium is necessary for an organism to fend off sickness, disease, or death."

This issue of Science Class can help you teach your students about regulation and behavior by demonstrating the common needs of organisms at all levels of organization. This foundation will help them in their future studies of adaptations and evolution.

Global Science Teaching

Seeking an Edge, Asian Teachers Visit American Schools

A recent Washington Post article details what science teachers from Singapore hope to gain from their visit to a magnet school in Virginia. The article quotes George Wolfe, director of the two-year-old public school, who asks, "How do you measure excitement? How do you measure creativity? There's so much publicity about Americans not scoring well on tests, but few people ask the question: Then why are we producing so much innovation from our scientists?"
