One of the main challenges in biotech is that we are often
working with things that are too small for our eyes to see. This
activity will help students put into perspective the relative sizes
between all the major microscopic structures inherent in
biotechnology.

For example, we can easily understand the difference in height
between a 25-story building and an 11-inch piece of paper, but did
you know this is the same relative size difference between a skin
cell and an influenza virus? Your student's probably don't!
