1. Key Questions
What is the difference between nanoscience and nanotechnology? How long have humans been using nanoparticles?

2. Activity 1: Relative Sizes of Objects
Go to L1.2 Activity 1 on Google Drive and find the sheet with your name.
Use the website to find the size of the objects and complete the worksheet.

3. Nanoscience vs Nanotechnology
What’s the difference?

4. Nanoscience or Nanotechnology. What do you think?

5. Activity 2: Brainstorm
What comes to mind when you hear the word “science” and the word “technology”?
Add your ideas to the Google Doc (L1.2 Activity 2 on Google Drive).
It is okay for an idea to appear in both columns.

6. Nanoscience
The study of structures and unique properties of matter at the nanoscale
An interdisciplinary field of science combining physics, materials science, chemistry, and related disciplines.
First example of a liquid crystal
Studied in 1888
Unusual properties (two melting points)
Unusual interaction with light
No interest at the time

7. Nanotechnology
The design, characterization, production, and application of structures, devices, and systems by controlled manipulation of size and shape at the nanometer scale
Further research into liquid crystals led to molecules being fine tuned to give properties suitable for the production of LCD screens.

8. Is doesn’t need to be either/or…
NANOSCIENCE NANOTECHNOLOGY
Identification of physical and chemical properties
Design
Application
Learning how to control and mass produce the material.
Nanosilver studied with a scanning tunneling microscope
Antibactierial properties of nanosilver are used in a number of products.

9. How long have we been using nanoscience?
History of Nano
How long have we been using nanoscience?

10. Activity 3: The History of Nano
Who and what have made major contributions to the progress of nanoscience and nanotechnology?
