Engaging with Google docs/spreadsheets

I could have students enter their height and arm span into a survey. I could then use the spreadsheet to pass out to groups to graph the results. This could be used in a unit involving scatter plots to talk about positive and negative correlation. You could also use it for line of best fit. I use to have to get the measurements one day, take it home and create a spreadsheet, and then continue the lesson the next day. For some strange reason, students love to see their data on a printed paper.
