Did you look at the turtle module included in the standard
distribution?  It's very simple, made for beginners, and fast enough
for simple plots (just turn off the tracer).  If you intend to
introduce the class to GUI's at some point I believe turtle is built on
the Tkinter canvas widget, which may be suitable as well.

However, if you're teaching scientific programming to more technically
advanced users you might be better off using matplotlib/ipython.  That
will get you a matlab-like enviroment with many advanced capabilities.
