Lieberherr, Martin – Physics Teacher, 2011
The centripetal acceleration has been known since Huygens' (1659) and Newton's (1684) time. The physics to calculate the acceleration of a simple pendulum has been around for more than 300 years, and a fairly complete treatise has been given by C. Schwarz in this journal. But sentences like "the acceleration is always directed towards the…

Mitts, Charles – Technology and Engineering Teacher, 2013
The kite design activity described in this article is "hands-on" and provides students the opportunity to learn and apply STEM concepts in the process of building and flying a traditional diamond-shaped bowed kite from scratch. Important components of the activity are that students read and follow instructions and lessons about the…

Royce, Christine Anne – Science and Children, 2013
In a remarkably brief period of time, humans have developed technology that allows space travel to become a reality. Rockets have been built, energy systems designed, and planetary forces understood. In the activities described in this article, students investigate space travel by designing their own rockets and manipulating variables to determine…

Bowling, Bethany; Zimmer, Erin; Pyatt, Robert E. – American Biology Teacher, 2014
Although the development of next-generation (NextGen) sequencing technologies has revolutionized genomic research and medicine, the incorporation of these topics into the classroom is challenging, given an implied high degree of technical complexity. We developed an easy-to-implement, interactive classroom activity investigating the similarities…

Janssens, Peter; Waldhuber, Megan – Bioscene: Journal of College Biology Teaching, 2012
This laboratory exercise investigates the phenomenon of cytoplasmic streaming in the fresh water alga "Nitella". Students use the fungal toxin cytochalasin D, an inhibitor of actin polymerization, to investigate the mechanism of streaming. Students use simple statistical methods to analyze their data. Typical student data are provided. (Contains 3…

Davidhazy, Andrew – Tech Directions, 2012
Sir Isaac Newton determined that the acceleration constant for gravity was 32 ft./per/sec/sec. This is a fact that most students become familiar with over time and through various means. This article describes how this can be demonstrated in a technology classroom using simple photographic equipment. (Contains 5 figures.)

Priest, Marie A.; Padgett, Lea W.; Padgett, Clifford W. – Journal of Chemical Education, 2011
A method for the construction of a Galilean thermometer out of common chemistry glassware is described. Students in a first-semester physical chemistry (thermodynamics) class can construct the Galilean thermometer as an investigation of the thermal expansivity of liquids and the temperature dependence of density. This is an excellent first…

Xu, Lihua; Clarke, David – Research in Science Education, 2012
This paper reports multi-layered analyses of student learning in a science classroom using the theoretical lens of Distributed Cognition (Hollan et al. 1999; Hutchins 1995). Building on the insights generated from previous research employing Distributed Cognition, the particular focus of this study has been placed on the "public space of…

Gillman, Joan – Science and Children, 2013
To capture students' excitement and engage their interest in rocketships and visiting planets in the solar system, the author designed lessons that give students the opportunity to experience the joys and challenges of developing straw rockets, and then observing which design can travel the longest distance. The lessons are appropriate for…

Bianco, Andrew S. – Technology and Engineering Teacher, 2014
All technology educators have favorite lessons and projects that they most desire to teach. Many teachers might ask why teach robotics when there are many other concepts to cover with the students? The answer to this question is to engage students in science, technology, engineering, and math (commonly referred to as STEM) concepts. In order for…

Zhu, Lixin – Bioscene: Journal of College Biology Teaching, 2011
For the purpose of teaching collegians the fundamentals of biological research, literature explaining the discovery of the gastric proton pump was presented in a 50-min lecture. The presentation included detailed information pertaining to the discovery process. This study was chosen because it demonstrates the importance of having a broad range of…

Bennett, Jonathan; Mauney, Alex – Physics Teacher, 2011
The problem of a ladder leaning against a wall in static equilibrium is a classic example encountered in introductory mechanics texts. Most discussions of this problem assume that the static frictional force between the ladder and wall can be ignored. A few authors consider the case where the static friction coefficients between ladder/wall…

Rosado, Dale A., Jr.; Masterson, Tina S.; Masterson, Douglas S. – Journal of Chemical Education, 2011
Mass spectrometry (MS) has been gaining in popularity in recent years owing in large part to the development of soft-ionization techniques such as matrix-assisted laser desorption ionization (MALDI) and electrospray ionization (ESI). These soft-ionization techniques have opened up the field of MS analysis to biomolecules, polymers, and other high…

Wajrak, Magdalena – School Science Review, 2011
Natural arsenic salts are present in all waters, with natural concentrations of less than 10 parts per billion (ppb). Unfortunately, there is an increasing number of countries where toxic arsenic compounds in groundwater, which is used for drinking and irrigation, have been detected at concentrations above the World Health Organization's…
