Surface Area to Volume Ratio

This simple activity conveys one of most profound aspects of nanoscience – that for a given volume of material the total surface area increases non-linearly as the volume is divided into smaller and smaller pieces.  This concept is being applied to creating better batteries and catalytic converters.  Students will measure the time it takes tablets broken into different numbers of pieces to dissolve.  Calculations of surface area and volume can also be performed.
