On February 1, 2015, the New England Patriots clinched a 28-24 point win against the Seattle Seahawks in Super Bowl XLIX. Going into the game, the Patriots were shrouded in controversy regarding possible deflated footballs in their American Football Conference (AFC) Championship game against the Indianapolis Colts, most notably known as…

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…

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…

The National Assessment of Educational Progress (NAEP), first administered in 1969, is the largest nationally representative and continuing assessment of what the nation's students know and can do in various subjects such as civics, geography, mathematics, reading, science, U.S. history, and writing. The results of NAEP are released as The…

Many of today's students have embraced an environmental ethic and are motivated by efforts to reduce waste or to remanufacture waste into viable products. In-class efforts to reuse and remanufacture waste can be especially motivating. They can also help students develop a better understanding of life-cycle analysis, waste-stream management,…

The rapid academic and industrial development of nanotechnology has led to its implementation in laboratory teaching for undergraduate-level chemistry and engineering students. This laboratory experiment introduces the galvanic replacement reaction for synthesis of hollow metal nanoparticles and investigates the optical properties of these…

The National Assessment of Educational Progress (NAEP) is the largest nationally representative and continuing assessment of what the nation's students know and can do in various subjects such as mathematics, reading, science, and writing, as well as civics, geography, U.S. history, and technology and engineering literacy. The results of NAEP are…

The National Assessment of Education Progress (NAEP) is the largest continuing and nationally representative assessment of what the nation's students know and can do in subjects such as civics, geography, mathematics, reading, U.S. history, and writing. The results of NAEP are released as The Nation's Report Card. NAEP is a congressionally…

This article describes the "Kick Stick" activity from Design Squad Nation, in which kids turn a wooden paint stirrer and circuit into a motorized, spinning arm--then use it to kick a Ping-Pong[R] ball across the floor. Teachers can enrich their students' exploration of circuits and emphasize the engineering design process with "Design Squad…

There is concern about the diminishing availability of skilled personnel that can operate in the wide variety of disciplines associated with port operations. Increasing cargo volume, combined with a shrinking workforce, could potentially create alarming situations in the future, hence the motivation to publicize to current students the breadth and…

There is concern in some counties about the number of able young people entering degree level study and careers in physical science, including chemistry. Too few of the most talented young people are selecting "STEM" subjects to ensure the future supply of scientists, engineers and related professionals. The present paper sets out general…

At a high school level, sometimes students can perceive math as simply another step towards graduation and learn just what is needed to get by. If realistic examples were used more often in classroom settings, then teachable moments would happen--and that is where inspiration can be fostered. This article provides thoughts and ideas behind the…

"Watch out, the stove will burn you," "Ooh, ice cream headache!" Students construct their conceptions about heat and temperature through their own intuitions about daily life experiences. As a result, misconceptions can be born from these constructed concepts. The activity described here addresses student misconceptions about thermal insulation…
