Abstract

This paper shows methodologies and results of a laboratory course in the frame of the POC program addressed to scientific high school students. The main objective of the activity was the use of contact angle measurements in a simple and easy to handle mode to explore surface properties of liquids and solids and search correlations with intermolecular forces. As a final task students have fabricated a superhydrophobic wood surface and have been guided in the interpretation of this extreme interface behavior.
