This study explored the psychosocial determinants of consumption of soda and other taxed sugar-sweetened beverages (SSBs) in Mexican construction workers (CWs) and whether consumption changed as a result of the 2014 SSB tax. We conducted a qualitative case study involving in-depth interviews and focus groups (FGs) with 30 Mexican CWs; supplemented…

Background: Among adolescents, physical inactivity and unhealthy dietary habits are associated with being obese. We know little about how those are associated with trying to lose weight. Methods: We analyzed the 2013 Centers for Disease Control and Prevention (CDC) Youth Risk Behavior Surveillance data (N = 13,583) to examine how obesity and…

Purpose: Individuals experiencing extended homelessness face multifaceted risks related to health, substance use, and continuing unemployment and may benefit from learning a problem-solving and decision-making method to assist them in dealing with everyday situations. Methods: This study used a multiple-baseline design to teach three men with…

This article reports on a new device, called a geyser guide, that allows for quantitative measurements of both bubble sizes and kinetics of foam production in the so-called Diet Coke and Mentos experiment. The device is easily constructed, is made using readily available materials, and allows the experiment to be carried out indoors with no mess.…

Objective: To determine differences in glucose control and cardiovascular disease risk factors following three weeks of added soda, 100% fruit juice, or water in apparently healthy, college-aged adults. Participants: Thirty-six adults (18 males; 18 females) between the ages of 18 and 30 years of age. Methods: A 3-arm randomized controlled…

Background: "Choose Health: Food, Fun, and Fitness" (CHFFF) is aimed at 3rd to 6th graders, and uses experiential learning, food preparation, active games, goal setting, and a family newsletter to target behaviors shown to decrease childhood obesity and chronic disease risk. This study aimed to evaluate CHFFF as intended in low-income…

A problem-solving experiment is a learning activity that uses experimental design to solve an authentic problem. It combines two evidence-based teaching strategies: problem-based learning and inquiry-based learning. The use of problem-based learning and scientific inquiry as an effective pedagogical tool in the science classroom has been well…

Background: Sleep deprivation adversely impacts cognitive performance. A nutritious diet is one strategy that can prevent sleep deprivation and its adverse effects. However, few data exist regarding the influence of diet on sleep duration among adolescents. Hence, it is important to assess whether dietary habits are linked to adequate sleep among…

Fostering metacognition can be challenging within large enrollment settings, particularly within STEM fields concentrating on problem-solving skills and their underlying theories. Herein, the research problem of realizing more frequent, insightful, and explicitly-rewarded metacognition activities at significant scale is investigated via a strategy…

Most children, when presented with the option between two drink items, will choose the one with "more." But what exactly do children consider when they recognize one object as having more than another? Is it the perceived surface area or volume of an object? Depending on children's cognitive development, the aspect of measurement on…

In a dramatic physics demonstration, a professional flutist produces four resonances with a 12 ounce Boylan soda bottle solely through her breath control. The 22cm bottle acts like a Helmholtz resonator for the lowest pitch. The three higher pitches fall near the 3rd, 5th, and 7th harmonics for a 22cm closed pipe. A video of this remarkable feat…

Background: There is little research on how affective reactions (e.g., stress) to "perceptions" of nutritious food accessibility contribute to dietary behaviors. Aims: This study explores whether stress associated with limited access to nutritious foods--termed "nutrition resource stress" (NRS)--contributes to diet outcomes,…

High-performance liquid chromatography is one of the primary techniques covered in the undergraduate analytical chemistry curriculum. This technology report describes the use of a portable capillary-scale instrument that can provide similar performance to a benchtop instrument but generates less solvent waste and enables operation in nonlaboratory…

The authors teach in a large, urban school district in the Midwest and typically a few students have parents who work in the sciences. One year, the authors were fortunate to have the child of the owner and head brewer of a local microbrewery. That coincidence set the stage for a major collaboration to bring the real world of chemistry and biology…

For many reasons, physiological aspects of anatomy and physiology laboratories are often presented as simulations. While simulations effectively convey concepts, hands-on activities promote more active student engagement. Recycled soda bottles, supplemented with other inexpensive readily available supplies, can be used to create working models…
