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…

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…

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).

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…

Kuntzleman, Thomas S.; Ford, Nathan; No, Jin-Hwan; Ott, Mark E. – Journal of Chemical Education, 2015
Everyone enjoys seeing the cloudy white fog generated when solid carbon dioxide (dry ice) is placed in water. Have you ever wondered what physical and chemical processes occur to produce this fog? When asked this question, many chemical educators suggest that the fog is produced when atmospheric water vapor condenses on cold carbon dioxide gas…

Stuckey, Marc; Eilks, Ingo – Journal of Chemical Education, 2015
This paper discusses a set of easy, hands-on experiments that inquire into and differentiate among tattoo inks of varying quality. A classroom scenario is described for integrating these experiments into secondary school chemistry classes. Initial experiences from the classroom are also presented.

Levine, Mindy; Serio, Nicole; Radaram, Bhasker; Chaudhuri, Sauradip; Talbert, William – Journal of Chemical Education, 2015
There continues to be a persistent, widespread gender gap in multiple STEM disciplines at all educational and professional levels: from the self-reported interest of preschool aged students in scientific exploration to the percentages of tenured faculty in these disciplines, more men than women express an interest in science, a confidence in their…

Franco-Mariscal, Antonio Joaquín – Journal of Chemical Education, 2015
This paper presents a project about the chemical elements made by 15-year-old Spanish high school students of Chemistry. It focuses on context-based teaching combined with the advantages of creating a large mural which subsequently is exposed in the school. The project consisted of researching the chemical elements in the different materials that…

Cady, Susan G. – Journal of Chemical Education, 2014
The circuit board found in a commercial musical greeting card is used to supply music for electrochemical cell demonstrations. Similar to a voltmeter, the "modified" musical device is connected to a chemical reaction that produces electricity. The commercial 1 V battery inside the greeting card circuit board can be replaced with an…

Marle, Peter D.; Decker, Lisa; Taylor, Victoria; Fitzpatrick, Kathleen; Khaliqi, David; Owens, Janel E.; Henry, Renee M. – Journal of Chemical Education, 2014
This paper discusses a K-12/university collaboration in which students participated in a four-day scenario-based summer STEM (science, technology, engineering, and mathematics) camp aimed at making difficult scientific concepts salient. This scenario, Jumpstart STEM-CSI: Chocolate Science Investigation (JSCSI), used open- and guided-inquiry…

Sewry, Joyce D.; Glover, Sarah R.; Harrison, Timothy G.; Shallcross, Dudley E.; Ngcoza, Kenneth M. – Journal of Chemical Education, 2014
Given the emphasis on community engagement in higher education, academic departments need to become more involved in the community. This paper discusses a number of outreach activities undertaken by the chemistry department at Rhodes University, South Africa. The activities range from service learning to community engagement with teachers and…

Moore, Emily B.; Chamberlain, Julia M.; Parson, Robert; Perkins, Katherine K. – Journal of Chemical Education, 2014
Developing fluency across symbolic-, macroscopic-, and particulate-level representations is central to learning chemistry. Within the chemistry education community, animations and simulations that support multi-representational fluency are considered critical. With advances in the accessibility and sophistication of technology,…

Pluth, Michael D.; Boettcher, Shannon W.; Nazin, George V.; Greenaway, Ann L.; Hartle, Matthew D. – Journal of Chemical Education, 2015
Decreased funding for middle and high school education has resulted in reduced classroom time, which, when coupled with an increased focus on standardized testing, has decreased the exposure of many middle school students to hands-on science education. To help address these challenges, we developed an integrated outreach program, spanning grades…

Nagel, Megan L. – Journal of Chemical Education, 2013
A trip to the mall is used as a classroom demonstration to illustrate the fundamentals of separations without the need for chemicals or any chemistry background. Student volunteers are the "mixture", and depending on the shopping list they have been given, they spend varying amounts of time in the "stores" versus moving through…
