I hope you’ve enjoyed the tours of nanoworld and microworld. In case you’d like a short list of things to remember, here are some suggestions.
In the microworld:
- 900 um – fly’s eye
- 100 um – paper
- 7 um – red blood cell (on the small side for a plant/animal cell)
- 1-10 um – bacteria, mitochondria, and chloroplasts
And in the nanoworld:
- 100 nm – viruses
- 10 nm – cell membrane
- 2 nm – DNA double helix
- 1 nm – glucose molecule
After completing this module you should be able to:
- Use appropriate units of length for different measurement contexts (milli-, micro- and nano- worlds)
- Convert units of length
If you want a printer-friendly version of this module, you can find it here in a PDF document. This printer-friendly version should be used only to review, as it does not contain any of the interactive material, and only a skeletal version of problems solved in the module.
