Nano Waterproofing

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics. Learners explore the hydrophobic effect and how similar properties can be introduced by reengineering products at the nano level. Learners work in teams to develop a waterproof material and compare their results with nano waterproof materials developed recently by engineers and scientists.
