Using the digital camera to see remote lights is always a terrific way to introduce or at least discuss what we mean by "observe". You can even set the digital camera up so that you can casually glance at it, give a student a remote and ask your class to try to tell when the remote is "on". After a moment of confusion you announce (by glancing at the digital camera) that you can see when a student has turned on a remote, telling them only that you can see in the infrared, let them try to figure out how you are doing it. Students need to know how science gains useful information "seeing" outside of the range that humans can use their own senses. It opens up the idea of "observing" and shows how other organisms "see" things perhaps a little different from us. Lots of good questions here.
 
This may explain the difference between the "red" states and the "blue" states in the last election, but I'm not sure how. Dunno.
 
With firm handshake,
