A MEMBRANE.

- Abstract
The article presents information on a membrane engineering related activity which integrates technology (biomedical, tissue, and mechanical engineering) and science, for students in Grades K to 12. In the simplest of terms, membrane can be defined as a barrier between two environments. Household items such as towels, napkins, sponges, and paper are good examples of membranes. This activity encourages critical-thinking skills and creativity by asking students to create and design an abstract scientific concept. The focus is on the student's ability to visualize the concept and then design, construct, and test their creation. The goal here is twofold: (1) students understand the concept of membranes, and (2) students understand the fundamental concepts in engineering design. The challenge here is for students to create a strong membrane. Properties such as membrane strength and its pore size will be tested. The students will design, construct and test their membranes. Teachers should guide students with questions about the data they collected. Teachers play a very important role throughout this activity. They should talk with students as they design and construct their membranes. Students should be encouraged to discuss ideas with other students as well as teachers.
