Zoom into a Lotus Leaf video

NISE Network product
Description: 

In this film "Zoom into a Lotus Leaf," see an up close look at the tiny nanostructures that give the leaf its unique behavior. The Lotus Leaf is a symbol of purity because it appears to be perpetually clean. We now know that its self-cleaning properties are due to its ability to repel water very effectively; it's superhydrophobic. It gets its superhydrophobicity from tiny nanostructures. We start with a normal digital camera and zoom in using increasingly powerful microscopes as we explore this phenomena.

Objectives

Big Idea: 
Nature, the master of nanotechnology, has created nanostructures that can repel water. Scientists can use this knowledge to understand how water interacts with nanometer sized objects. This knowledge can and has sparked new innovations in technology and material science.
Learning Goals: 
  • As a result of viewing this video, viewers will appreciate that nanotechnology can be found in living things like the Lotus Leaf.
NISE Net 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.
  • Nanoscience, nanotechnology, and nanoengineering lead to new knowledge and innovations that weren't possible before.
