In the Windows Around the World program, we are using web cameras to collect visual images that are used as data. These images are stored in a database and can be used to see changes in day length through out the year in various places around the world. In the attached handout, I have created a matching excercise that lets students see the changes in Arctic day light and to practice using pie graphs. This worksheet is designed primarily for 4th-6th grades but it could be modified for older and younger students. If you wish to see other filmstrips, you can view them by going to the "Weather Archive" section of the site, located under the "Teachers' Resouces".

In a daily filmstrip, there are 24 blocks, with each block representing one hour. The black boxes represent darkness and the light boxes represent day light. If you submit a pie graph showing the daylight in your town and want it to be displayed on the Windows Around the World website, please e-mail it to This e-mail address is being protected from spambots.
