The charge memo provided a very open-ended design task (this is the second design course; the first is a much more traditional chemical engineering process design experience). b. Each team needed to work on a tight schedule to produce recommendations for the "client". While chemical engineering issues were the primary focus of the team's work, the context of the design challenge required understanding of multidisciplinary issues

Finally, some demonstrations required pumps or other forms of moreexpensive/complicated lab equipment (for example, [9] - [11]), which would not be ideal for asimple demonstration during a lecture course.For this project, a fixed-bed adsorption demonstration was developed that is not only relativelylarge in size, is also very cheap, safe, and colorful. Furthermore, the demonstration could beeasily expanded to be a short lab activity that could be completed by student teams to examinethe effects of several key variables, such as bed height, contaminant concentration, etc.Construction details for the demonstration are provided in Appendix B.

Blockade of the K+ flux allows fewer K+ ions to flow through themembrane than Na+ ions, i.e., only those carried by the low K+ selective NaX will cross on theNaX side. Hence, the voltage will change and move towards the Na+ equilibrium

This software, OSBLE (Online Studio-Based Learning Environment), provides anonline environment designed to facilitate peer review of students’ code solutions.14 OSBLEsupports three user interfaces: (a) student; (b) instructor; and (c) code moderator. Studentssubmit code solutions to be reviewed through the system. Once they have done so, their solutionsbecome "locked": they may no longer modify them, but they now have access to the codesolutions of their peers. Thus, a period of on-line code review can begin. Students areencouraged to view the solutions of the members of their review team, to identify issues withthose solutions, and to log those
