using hot blocks of metal as an energy source. One option is to use one metal block at a temperature of 200 C and a second option is to use two metal blocks each at a temperature of 100 C. All the metal blocks are made from the same material and have the same weight and surface area. Which option will melt more ice? a. the 100 C blocks b. the 200 C block c. either option will melt the same amount of ice d. can’t tell from the information given because: e. 2 blocks have twice as much surface area as 1 block so the energy transfer rate will be higher when more blocks are used f. energy transferred is proportional to the mass of blocks used and the change in block temperature

Appendix B gives a simple description ofbackground concepts involved in the lesson, which is intended for instructors unfamiliar with theapplications.Connections to Chemical EngineeringThe authors are chemical engineering faculty and interdisciplinary students in the research labsof those faculty. While the activities for the BME major at Grandparent University are themedaround two major organs in the human body, the authors designed the activities to emphasizeseparation process principles and transport phenomena—two key areas of the chemicalengineering curriculum. The kidney activities focus on filtration involving both adsorption tosurfaces and pore and particle size-based

two-phase flow pipe assembly was shown. Ademonstration running a two-phase flow of water and air was conducted, including discussion ofthe utility of computer interfaces and control valves. Students liked the demonstrations andasked a number of questions regarding the computer interface.6. Oral presentations After a lunch break, during which experiments continued, the students returned toconclude their experiments. Each group was asked to present the experimental observations/outcomes as a team. They were provided 10 minutes of preparation time. During this recess,they were also told that a) the presentation should be a group effort, b) all members should berespectful to other group members, and c) the audience should ask questions
experimentation.The specific procedure for this activity utilizes about 75% (by weight) excess methanol, but thisis not disclosed to the students. Instead, students are asked to use Equation 1 and the physicalproperties of the reactants and products (as given in Table 1) to determine the theoretical amountof methanol that reacts with 1 L of oil. They are then asked to compare this value to the actualamount of methanol used and re-write the equation to include the excess methanol. Each of thespecific tasks assigned as part of this activity are described below.Task #1: Re-write the stoichiometric chemical reaction for biodiesel production in terms of a.)moles of products and reactants, and b.) volume of products and reactants.Task #2: Record or calculate the

A suitable problem for the DST is defined as an authentic, real-world design problem that has yet to be solved, and that would require significant effort, time,and expertise to solve; the purpose of the DST is not to assess ability to solve a design problem,but rather to measure how students get started framing a design problem.We located two appropriate problems for the DST, both from an email requesting ideas forsolving technological problems, issued by Deutscher Technologiedienst GmbH (used withpermission, and with minor adaptations for our purposes, see Appendix B & C).The DST was given during class time in the first week of class. Students were given 15 minutesto

Page 23.1061.3Course structure & Role of concept development projectsIt is widely touted that the use of research ideas can create excitement for learning in theclassroom8-12. The primary course goals were to a) enhance student familiar with small-scaletechnology with a focus on biomedical diagnostic applications, and b) to develop basicinformation synthesis skills essential for research within a single semester. The course coveredboth
innovations are beyond the scope of thiswork, but a significant literature can be found (e.g., [8, 9]).Textbook reading rates for this course have been discussed previously [10-12]. Specifically, highreading rates – median reading rates greater than 90% - have been observed [11], while limiteddata over recent decades show significantly less reading for traditional textbooks [10, 12, 13].While reading rates were reproducibly high for two previous cohorts, several other findings arealso of note. While interactive textbook reading is an effort-based activity and grade, statisticallysignificantly higher reader rates were observed for students earning A and B grades in the coursecompared to C, D, and F cohort [10].

4) and any recommendations and action items that require attention from the safety perspective.Initial feedback was varied, with some students performing a very thorough review, othersproviding very little information. Process and instrumentation diagrams were included inseparate sections of the student reports. Appendices A and B include two of the best reportsprovided by the students. Not all students followed the tabulated formats to collect theinformation. In some cases this led to lack of clarity; in others, the chosen format was clear andconcise, nonetheless. We expect greater consistency in the PHA responses in the fall 2013course, and will evaluate and compare results as the first full cycle comes to a close.Concluding
