concerning innovative material and advances inmaterial science. During one month the student’s topic was biomaterials. The portfoliosincluded six articles of the individual students choosing, an executive summary and a brief classsharing reflection of the most interesting article. Anecdotal feedback from the students was quiteexciting. As another exercise in the course a biomedical device manufacturers was contactedand a supply of their newly developed Bone cement was donated to the class. This materialoffered another opportunity to study the function, shape and material of human bone and testhow this material forms a suitable substitute. Plans for the current semester include a bonetesting lab. Portions of the exercise are shown below. The

useexperimental data to validate or rejecttheir hypotheses. In the assignment as Figure 1: Raw (R) and hardboiled (B) eggs after 24well, higher-level questions that hours of incubation in water (1), syrup (2) and energyelevate the critical thinking skills of drink (3).the students were given. For example,students were asked to explain why boiled and raw eggs behaved differently in transportingsolutions (Figure 1)? Answers should have reflected on the concepts of permeability and proteindenaturation at elevated temperatures. In their assignment too, students were asked to quantifythe diffusion across the cellular membrane as well as the ionic strength concentration of the innerenvironment of the egg using Fick’s law. Based on their
