Logarithmic Lions

Lions: 1,2,...many, logarithmic thinking.

This lesson was designed after a national geographic article I read some years back, and I wish I had a copy or knew the name of the article.

Here's the lesson:



Show this flip (its in Smart Notebook, sorry ActiveInspire).  Each student has to write down the number of predators they see, but I only show the slide for a fraction of a second.





Which leads to the idea that the human brain was wired to think logrithmically.  Evolution favored those who could discern the difference between 1 lion, 2 lions and 3 lions, but no favor is granted to those who can tell the difference between 9 and 11, as they are dead meat anyways.

This intro is a fun activity and is a non-threatening way to show semi-log scales.
