Schoeddert, Alex; Babooram, Keshwaree; Pelletier, Sarah – Journal of Chemical Education, 2019
A low-cost and easy-to-use water recirculation system for a condenser apparatus was designed and installed in an organic chemistry teaching laboratory. Relying on gravity and a small pump for water circulation, it supplies four stations simultaneously. The water recirculation system works very well with condensers used for distillation and reflux…

Problems associated with the environment loom large over the future well-being of young generations. A previous issue of PISA in Focus (PISA in Focus 87) shows that in 2015 many 15-year-old students believed that the future -- their future -- was going to be worse, environmentally, than the present. In particular, only a minority of students…

Geng, Jianming; Chen, Kaiyuan; Wang, Nengxin; Ling, Sihan; Guo, Muqi; Huang, Zuyi – Chemical Engineering Education, 2019
US high school (HS) students are lagging behind their foreign peers in math performance. It is thus necessary to design teaching modules that motivate US HS students to learn more math and to improve their math skills. Our study set out to test two different software programs designed for the development of such skills. MATLAB Simulink provides a…

Divya, Damodaran; Raj, Kovummal Govind – Journal of Chemical Education, 2019
A practical approach for synthesizing functional material from waste material is described. The work was carried out by chemistry undergraduate students as a group project. The concepts used mainly in inorganic quantitative approaches were applied to transform an iron-containing material to magnetic iron oxide nanoparticles. The magnetic…

Tietz, Paul I. – Natural Sciences Education, 2019
Hydraulic fracturing is a major process for oil and natural gas production in the United States, and sand mines in Western Wisconsin provide highly desirable sand for the fracturing industry. After being mined, sand is wet-sieved to isolate economical-size fractions. Polyacrylamide is used as a flocculant to settle out the fine particles,…
