Science teachers and mentors continue to be challenged to meet the high expectations of "A Framework for K-12 Science Education" and the "Next Generation Science Standards." Indeed the Framework urges teachers to help learners "[build] progressively more sophisticated explanations of natural phenomena..." while the…

Molecular similarity is one of the strongest lines of evidence for evolution--and one of the most difficult for students to grasp. That is because the underlying observations--that identical mutations are found in closely related species and the degree of similarity decreases with evolutionary distance--are not visible to the human eye. And it's…

Using the life sciences, this article first reviews essential features of the "NRC Framework for K-12 Science Education" that provided a foundation for the new standards. Second, the article describes the important features of life science standards for elementary, middle, and high school levels. Special attention is paid to the teaching…

Life as people know it here on Earth exchanges energy and materials with the environment. Life forms grow, develop, produce waste products, and reproduce, storing genetic information in DNA and RNA and passing it from one generation to the next. Life evolves, adapting to changes in the environment and changing the environment in return. The basic…

While teaching science in an alternative arts high school, the author continuously addresses the challenge of welcoming creative, right-brained students into the world of systematic inquiry. Busily mixing paint colors, choreographing futuristic dances, performing comedic theater, and practicing the banjo, the students rarely initiate authentic…
