This is a lesson plan on surface engineering, developed to help teachers integrate engineering practices in the secondary classroom. Students learn about nanotechnology and its application in developing hydrophobic surfaces. (Hydrophobicity is a physical property, and is defined as the tendency of a molecule to repel water.) Students work in teams to to design a roof from simple materials that will keep the contents of a box dry during a water test. The driving question of the lesson: How do civil engineers apply principles of nanotechnology to develop waterproof roofs?
This resource includes objectives and learner outcomes, problem sets, student guides, recommended reading, illustrated procedures, worksheets, and background information. Hydrophobic molecules tend to be non-polar, whereas H2O is a polar molecule. Examples of hydophobic molecules include oils and fats. But as the size of objects is reduced to the nanoscale, the effects of surface properties become even more pronounced. To extend this lesson, See Related Materials for an article by the Nanoterra Group that provides information on newer applications of nanotechnology in surface design. This collection is part of TryEngineering.org, a website maintained by the Institute of Electrical and Electronics Engineers (IEEE).
