Lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items, from paint to fabrics. Students learn about the hydrophobic effect and how similar properties can be introduced by reengineering products at the nano level. Students work in teams to develop a waterproof material and compare their results with nano waterproof materials developed recently by engineers and scientists.
8 – 18
- Learn about nanotechnology.
- Learn about the hydrophobic effect.
- Learn about surface area.
- Learn about teamwork and working in groups.
Anticipated Learner Outcomes
As a result of this activity, students should develop an understanding of:
- surface area
- problem solving
Students learn about how nanotechnology has impacted manufacture and use of fabrics. Students then work in a team to develop a waterproofing plan for a piece of cotton fabric, they execute their plan, test the fabric, and examine samples of fabrics that have had their surface altered through nanotechnology.
