Logarithms are very handy when dealing with numbers at lots of different scales (see related PUMAS example: Just What is a Logarithm, Anyway?). But they also have another useful feature: they help us average measurements of physical phenomena that have nonlinear behavior. A common example in my field of study relates cloud “albedo” to cloud optical depth (Fig. 1); but similar examples may be found when examining many natural phenomena.

"Enjoyed the activity, BUT it is currently shown in the K-2 section of Puma. Definitely should be in High School section."
