This is a class research project that results in an excellent classroom poster. I use it in conjunction with the unit on the Industrial Revolution. But if your school is named "St. Patrick's" you may want to do it some time in March.
The Irish were recruited to work on the Eire Canal, but did they stay in the neighborhood? Research the churches named for the patron saint of Ireland that were built near the canal.
This has always been a very high interest assignment.
