Photoperiod is the amount of time of daylight on a given day. Look up the sunrise and sunset times for today. Click the green flag. Answer when asked. I wonder how the photoperiod where you live compares with...? Why is it different in different locations?
I have been fascinated with changes in the photoperiod for a long time. It is interesting to notice variations at different latitudes. This project could be used by young children as part of a daily routine (calendar, weather, etc.). For older students: When students work with elapsed time math calculations, I find that it is hard for them to remember about regrouping an hour to 60 minutes before subtracting minutes. This could be used to check their work. As I coded the math, my hand calculations and the generated solution did not match. I took the code apart and checked it line by line. Oops! I incorrectly selected from the drop down menu for one of my variables. All's well that ends well! I know this is not glitzy. My thought is that the amount of glitz depends upon how the project will be used. For the two utilitarian applications mentioned above, I think that basic is best. However, for other applications, a remix with an entertainment component would be nice. For example, a sunrise and sunset in the background. Perhaps I would add music such as "Sunrise, Sunset" from Fiddler on the Roof.
