Leslie just happened to finish her graph first. I let her decide which cities to put on the graph. She tried to chose one city from every ten degrees. We wish we had more data from the Southern Hemisphere to 'round out' the data. (g) Leslie followed the patttern of a graph that Leisa posted earlier from her meteorologist friend, Ken, in Florida. The kids gathered the data from our Math Penpal messages. We could spend ages locating each city. Before I gave them the chart that Leisa sent I made them calculate the hours of daylight by subtracting sunrise time from sunset time. That in itself was a lesson.
