What is the difference between nanoscience and nanotechnology?

How long have humans been using nanoparticles?

Key Questions

Activity 1: Relative Sizes of Objects

1. Go to L1.2 Activity 1 on Google Drive and find the sheet with your name.

2. Use the website http://htwins.net/scale2/ to find the size of the objects and complete the worksheet.

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.

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

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.

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.

Activity 3: The History of Nano

Scientist/Technology Year Summary

Who and what have made major contributions to the progress of nanoscience and nanotechnology?

• Find your table in the Google Presentation (L1.2 Activity 3 on Google Drive)

• Use the website http://www.discovernano.northwestern.edu/whatis/History/

• Prepare a summary of 5 scientists and 3 technologies that have prompted advances in the fields of nanoscience/nanotechnology

Home Learning

• Select one scientist and one technology from your list to study in more detail.

• Prepare six PowerPoint slides that meet the following criteria.– Slide 1: Title slide– Slides 2 and 3: Chosen Scientist (combined max. 80 words)– Slides 4 and 5: Chosen Technology (combined max. 80 words)– Slide 6: References

• You may use pictures/diagrams to enhance your presentation.

• Upload your presentation to the RAFL (Realsmart).
