Science Buddies: "Ask an Expert"

I am doing a science project using Fermi Estimates. I want to know how long it would take a molecule of air to be breathed by everyone on earth. There is no hypothesis, just mathematics. What is a science fair board layout I can use?

jensen1,

Using this page as a reference:

http://en.wikipedia.org/wiki/Fermi_problem

I would suggest a layout that has your question as the board title and shows your breakdown of the estimate starting on the left and right sides (these would be the numbered entries on the wikipedia page), with arrows pointing to the center panel where you tie everything up into your final estimate (these would be the actual calculations on the wikipedia page culminating in the result). This would lead the viewer's eye between the parts on the periphery and the conclusion in the center. Most likely, their gaze will go back and forth seeing how the parts flow into the final conclusion. The equations may be below the final result, so that the result would be visible from farther away. People would see the question and the answer from far away, and approach to see how you got it. There might be a brief and concise explanation of Fermi estimates on the upper part of one of the side panels (or somewhere easily visible) so they can understand your approach.

Good luck!
