Boys, Alexander J.; Walsh, Mark C. – Journal of Chemical Education, 2019
Elementary and middle school science curricula typically focus on generating an interest in science and engineering through the use of hands-on activities that demonstrate specific concepts. Laboratory activities designed in this manner often circumvent some of the main challenges that engineers and scientists face, namely balancing advantages and…

Pino, Hernan; Pastor, Vanesa; Grimalt-Álvaro, Carme; López, Víctor – Journal of Chemical Education, 2019
In this article, a low-cost and pocket-sized setup for measuring CO[subscript 2] is presented. This setup is based on Arduinos, making it economic and open to modifications or improvements that satisfy other needs. It is composed of an Arduino board, a CO[subscript 2] sensor, an SD-card module, and a control panel. The device has been tested in…

Dean, Natalie L.; Ewan, Corrina; Braden, Douglas; McIndoe, J. Scott – Journal of Chemical Education, 2019
Comprehension of the 3D structure of objects usually represented in 2D is a critical part of understanding molecular geometries. The frequency with which students actually get hands-on with 3D molecular structures is often limited to a singular laboratory session. We sought to develop a set of molecular shapes that were inexpensive enough not only…

Kizilaslan, Aydin; Sozbilir, Mustafa; Zorluoglu, Seraceddin Levent – Journal of Chemical Education, 2019
Science education could be made more accessible to students with visual impairments through collaboration and specific adaptation in both the science classrooms and laboratories. For example, by providing simple adaptations or doing some essential modifications, students can gain experience with measuring, balancing, and weighing a variety of…

Dyer, Robert M. B.; Venton, B. Jill; Maeng, Jennifer L. – Journal of Chemical Education, 2018
University of Virginia, like many other universities, has developed a chemistry outreach program (called Chemistry Learning through Experimentation, Awareness, and Demonstration; i.e., Chemistry LEAD) that visits K-5 schools and teaches inquiry-based chemistry lessons in order to engage local students with science. Chemistry LEAD is graduate…

Sereda, Grigoriy; Hawkins, Benjamin – Journal of Chemical Education, 2018
We report a series of three experiments that introduce students at different stages of their academic preparation to the medical applications of hydrogels for controlled drug delivery and wound healing. The laboratory activity bridges the fundamental concepts of chemistry (acids and bases, equilibria, solvation, and reversible esterification) with…

Kuntzleman, Thomas S.; Davenport, Laura S.; Cothran, Victoria I.; Kuntzleman, Jacob T.; Campbell, Dean J. – Journal of Chemical Education, 2017
When carbonated beverages (which are supersaturated solutions of aqueous carbon dioxide) are confined within a narrow-necked container, events which rapidly release the gas from solution produce a fountain out of the beverage. One well-known variant of this experiment is the addition of Mentos candies to a bottle of Diet Coke. Previous reports…

DeKorver, Brittland K.; Choi, Mark; Towns, Marcy – Journal of Chemical Education, 2017
Chemical demonstration shows are a popular form of informal science education (ISE), employed by schools, museums, and other institutions in order to improve the public's understanding of science. Just as teachers employ formative and summative assessments in the science classroom to evaluate the impacts of their efforts, it is important to assess…

Ngai, Courtney; Sevian, Hannah – Journal of Chemical Education, 2017
Chemical identity, the idea that every substance has at least one property that makes it unique and able to be differentiated from other substances, is core to the practice of chemistry. Such practice requires using properties to classify as well as to differentiate. Learning which substance properties are productive in chemical identity thinking…

Boyle, Timothy J.; Sears, Jeremiah M.; Hernandez-Sanchez, Bernadette A.; Casillas, Maddison R.; Nguyen, Thao H. – Journal of Chemical Education, 2017
The Chemistry Science Investigation: Dognapping Workshop was designed to (i) target and inspire fourth grade students to view themselves as "Junior Scientists" before their career decisions are solidified; (ii) enable hands-on experience in fundamental scientific concepts; (iii) increase public interaction with science, technology,…

Cersonsky, Rose K.; Foster, Leanna L.; Ahn, Taeyong; Hall, Ryan J.; van der Laan, Harry L.; Scott, Timothy F. – Journal of Chemical Education, 2017
Despite the prevalence of polymers in modern everyday life, there is little introduction to the topic in science education throughout primary or secondary schooling in the United States. Of the few states that do include polymer education, this is only found at the high school level, primarily in biology or chemistry. Over the past year, we have…

Cipolla, Laura; Ferrari, Lia A. – Journal of Chemical Education, 2016
A hands-on approach to introduce the chemical elements and the atomic structure to elementary/middle school students is described. The proposed classroom activity presents Bohr models of atoms using common and inexpensive materials, such as nested plastic balls, colored modeling clay, and small-sized pasta (or small plastic beads).

The rise in carbon dioxide (CO[subscript 2]) concentration in the Earth's atmosphere, and the associated strengthening of the greenhouse effect, requires the development of low carbon technologies. New carbon capture processes are being developed to remove CO[subscript 2] that would otherwise be emitted from industrial processes and fossil fuel…

Woelk, Klaus – Journal of Chemical Education, 2015
In a classroom or take-home activity, students are challenged to write their name as a combination of chemical-element symbols and calculate "their" molar mass. Age-appropriate versions ranging from middle school to entry-level college classes are discussed. Acceptable molar-mass suggestions may be used in a competition for the heaviest…

Hudson, Reuben; Glaisher, Samuel; Bishop, Alexandra; Katz, Jeffrey L. – Journal of Chemical Education, 2015
A multiple day activity for students to create large-scale plastic objects from the biopolymer chitin (major component of lobster, crab, and shrimp shells) is described. The plastic objects created are durable and made from benign materials, making them suitable for students to take home to play with. Since the student-created plastic objects are…
