Kudos for for the educational marketing campaign by Evolution Window Films of Welland, Canada.  The owner installed window film for free for a class of Grade 3 students at a local elementary school.  In one stroke, he is protecting kids from heat and UV coming in from western-facing windows.

The education for the kids doesn’t stop here!  Evolution Films supplied students with thermometers prior to installation to measure temperatures on surfaces in the room.  Now the students can compare the difference in temperature prior to and after installation of window film.
