Crowe, Charles D.; Hendrickson-Stives, Albanie K.; Kuhn, Stephanie L.; Jackson, Jennifer B.; Keating, Christine D. – Journal of Chemical Education, 2021
The interaction between water and surfaces is observed in our daily lives and is used in laboratories to study materials properties, such as interfacial tension. Making the connection between fundamental scientific phenomena and everyday observations is a powerful method of highlighting the importance and relevance of science to the K-12…

Schmidt, Benjamin; King, David; Kariuki, James – Journal of Chemical Education, 2018
A reference electrode is an essential component of all three-electrode electrochemical measurements. Common commercial reference electrodes, including the saturated calomel electrode and Ag/AgCl reference electrode, are expensive with the former containing toxic mercury. Cheaper alternatives have been proposed including Ag/AgCl references made…

Wright, Lael; Shaw, Daniel; Gaidds, Kimberly; Lyman, Gregory; Sorey, Timothy – Science and Children, 2018
Although solving an engineering design project problem with limited resources or structural capabilities of materials can be part of the challenge, students making their own parts can support creativity. The authors of this article found an exciting solution: 3D printers are not only one of several tools for making but also facilitate a creative…

Chien, Yu-Hung – EURASIA Journal of Mathematics, Science & Technology Education, 2017
This study developed an integrated-STEM CO[subscript 2] dragster design course using 3D printing technology. After developing a pre-engineering curriculum, we conducted a teaching experiment to assess students' differences in creativity, race forecast accuracy, and learning performance. We compared student performance in both 3D printing and…
