We are starting to look at the Titanic "by the numbers". After reading background information about the crew, students made graphs all of the different jobs the crew held. I had no idea when I made the assignment that there would be hundreds of different job descriptions. We used a Web 1.0 application Create a Graph (been around forever, but recently updated) to create our graphs.
The sixth graders then took a look at the passengers and charted their nationalities. The charts made it clear that most of the first class passengers were from America and most of the third class passesngers were not! You can see all our charts and graphs here.
Here is another site, CIESE, that has outstanding activities using "real" data.
