Imagine a high school with very few experimental resources and limited budgets that prevent the purchase of even basic laboratory equipment. For example, many high schools do not have the means of experimentally studying radioactivity because they lack Geiger counters and/or good radioactive sources. This was the case at the first high school one…

Pacific Lutheran University (Tacoma, WA) is renowned for the number of its courses that offer international and study-away opportunities. Inspired by the theme of sustainability, and my growing concern about the environmental impact of conventional fuels, I offered a course, Physics of Energy, for the first time during PLU's January 2011 term (a…

The sugar maple, "Acer saccharum," is projected to decline and die in 88 to 100 percent of its current range in the United States. An iconic symbol of the northeastern temperate forest and a dominant species in this forest, the sugar maple is identified as the most sensitive tree in its ecosystem to rising temperatures and a warming…

Populations of the Eastern subterranean termite, "Reticulitermes flavipes," are widespread throughout most of the eastern United States. Subterranean termites have the ability to survive flooding conditions by lowering their metabolism. This lesson investigates the connection between the ability of termites to lower their metabolism to…

This article addresses misconceptions surrounding the Coriolis force and describes how it should be presented as a function within inertial and noninertial frames of reference. Not only does this demonstrate the nature of science as it strives to best interpret the natural world (and presents alternative explanations), but it offers a rich…

All writing begins with ideas, but young students often need visual cues to help them organize their thoughts before beginning to write. For this reason, many elementary teachers use graphic organizers or thinking maps to help students visualize patterns and organize their ideas within the different genres of writing. Graphic organizers such as…

Early childhood educators have long debated how science should be introduced and taught to preschoolers. In the current Science, Technology, Engineering, and Mathematics (STEM) education climate, this conversation has expanded to include the role of engineering in the preschool curriculum. Instructors and coaches in the professional development…

Industrial purification of biomolecules is commonly based on a sequence of chromatographic processes, which are adapted slightly to new target components, as the time to market is crucial. To improve time and material efficiency, modeling is increasingly used to determine optimal operating conditions, thus providing new challenges for current and…

Halfway through the 2015 AFC Championship game between the New England Patriots and Indianapolis Colts, game officials discovered that the Patriots were using underinflated footballs on their offensive snaps. A controversy ensued because the Patriots had actually supplied these balls to the game's referee just hours before kickoff. Athletes and…

The relationships among future-oriented motivation, self-efficacy, task values of science, and achievement outcomes were investigated among 15-year-olds across four Asian nations who participated in the Program for International Student Assessment (PISA) of the Organization for Economic Cooperation and Development (OECD). The factor structure of…

This research involves a multi-year study examining the perspectives and classroom practices of 21 middle school mathematics and science teachers, in the southeastern United States, participating in professional development (PD) exploring science, technology, engineering, art and mathematics (STEAM) literacies. This study sought to understand…

Raising awareness about sustainability is an urgent need and as such education for sustainability has gained relevancy for the last decades. It is acknowledged that science education can work as an important context for educating for sustainability. The goal of the present paper is to describe a role-playing activity about the construction of a…

This article presents a simple design challenge, based on the PBS program "Design Squad's" "Watercraft" activity that will prove engaging to most technology and engineering students. In this floating boat challenge, students are to build a boat that can float and support 25 pennies for at least 10 seconds--without leaking, sinking, or tipping…

The HK-1 "Hercules" airplane made its maiden flight over 60 years ago, and it still holds the record as the airplane with the largest wingspan that ever flew. Powered by eight massive 28-cylinder engines, it was piloted by Howard Hughes during its one brief flight in California. A large portion of the airplane was made of wood, which…

The growth of a pine tree is examined by preparing "tree cookies" (cross-sectional disks) between whorls of branches. The use of Christmas trees allows the tree cookies to be obtained with inexpensive, commonly available tools. Students use the tree cookies to investigate the annual growth of the tree and how it corresponds to the number of whorls…
