Increasingly, science teachers are expected to devote instruction to technology and engineering, as encouraged by the Next Generation Science Standards (NGSS Lead States 2013). Just as scientific literacy requires understanding the nature of science (NOS), technological literacy must include understanding the philosophy and nature of technology…

Students often confuse the functional differences between motion "transmission" and "transformation" systems. Students find it difficult to conceptualize differences between the specific systems. In this article, the author describes a technology and engineering unit that incorporates problem-based learning (PBL) to assist…

Nanoscience development affects almost every discipline of science, engineering, and technology. Not surprisingly, "the science of small" is also finding its way into science classrooms. In general, "nano" refers to a billionth of a meter--about 1/50,000 the width of a hair follicle. The term "nanoparticle" usually…

Helping students understand the Nature of Science (NOS) is a long-standing goal of science education. One method is to provide students examples of science history in the form of short stories. This article modifies that approach, using historical case studies to address both the history of science and the history of technology, as well as the…

Materials science--the science of stuff--has made our lives better by making it possible for manufacturers to supply us with products. Students have misconceptions about materials use. Many may think using bottled water, for example, is harmless because they recycle the plastic empties, but they fail to consider the resources and energy used to…

As a high school physics teacher, Kim Geddes is constantly searching for new experiences to challenge, motivate, and engage students. Last year, she incorporated ExploraVision into the energy unit of her school's physics curriculum with the help of their media specialist (Elease Franchini). ExploraVision is a competition offered through a…

What makes an outstanding book for a young reader? Although it would be hard to create a rubric for every book, experienced teachers recognize them quickly. They fascinate and captivate with both their content and style. Award-winning trade books inspire young readers to want more... more information, more books, more inquiry, more science. The…

Describes reasons why more emphasis should be placed on science education, particularly the technological aspects of science education. States that to make educated decisions about technology, students must first understand science as the basis for technology. Cites examples of technological advances emphasizing the need for increased science…

Introduces an interdisciplinary project called Learning Chemistry through Science Literature and Technology that involves the collaboration of a high school and an elementary school in Florida. Groups of elementary and high schools students produced science storybooks by using technology to record on CDs. (YDS)

Exploration of the underwater world by students is proposed as a motivation for acquiring scientific knowledge. Safe skin diving practices are directly related to scientific laws. (CP)

Introduces a science unit on heart rate variability (HVR) patterns. Uses spectral analysis to determine the effects of environmental stimulants such as music and emotional stress on heart rate. Observes relaxation techniques and their effects on the autonomous nervous system. (Contains 12 references.) (YDS)

Describes some contributing factors to environmental crises and argues that the population of the United States will act to correct some of the causes of deterioration if they are provided with the facts by scientists and teachers. (AL)

Introduces the Global Positioning System (GPS) and explains its use in the science classroom. (YDS)
