Intro to Exponential Functions

So we started our Exponential and Logarithmic Functions unit in Pre-Cal today.  I started by showing this bit from Mythbusters:

There's a nice little bit about exponential growth in the video, and they even make comments like "the size of the paper got really small really quickly", which segues nicely into this activity that I found on the PBS website (see pages 9-10 for student handouts):

Exponential Growth Activity

Here's another video that's good too.  You can use instead of (or in addition to) the Mythbusters video.

Tomorrow we'll start solving exponential equations.  I'll be using Kate Nowak's Add 'Em Up Activity.  Cant' wait!
