Coffee Break with Nanoscience: Film Formation and "Coffee Rings" (Middle/High School curriculum lesson)

Linked product

This lab will explore the phenomena involved in making thin film coatings. Students will explore the problems that crop up in real- life coating applications, and see how to avoid coffee rings and reduce cracking during the drop-casting deposition of a thin film.


Nano Content Map: 
  • Nanometer-sized things are very small, and often behave differently than larger things do.
  • Scientists and engineers have formed the interdisciplinary field of nanotechnology by investigating properties and manipulating matter at the nanoscale.
