Introducing the Normal Distribution using Hand-span (2.04e, 2.04f, 2.04g)
This applet can be used to help introduce to the normal distribution by looking at hand span in the context of key board sizes.
It can then be used to explain transforming to a standardized distribution and as a basis to examine assumptions for modeling using a normal distribution.
A full explanation is given of how this applet can be used here;

The second applet provides some actual data from a class I used this with which may be useful.
