A "simple" way to demonstrate Infra red ( near visible infra red....NOTdeep infra red (thermal)) - is with any standard web camera or even digital camera with a display screen.
 
the imaging chips in these ( and standard video tape based cameras) are sensitive to infra red ( and UV).. the manufactures put a filter over the detectors to reduce the sensitivity to these wavelengths, but the cameras will still detect and display infra red.
 
setup the camera and point an infra red remote control at the camera, you'll see the infra red diode come on..and flash...if you wire up an infra red diode you can create an infra red torch....
 
hope that helps..

I have used ultraviolet sensitive beads with kids to demonstrate that the
sun gives off more than just visible light.  While indoors, we string them
up on a lanyard or on a pipe cleaner (for a bracelet).  Then we take them
outside and watch them change from clear to their various colors.  I call
them sunburn detectors.  The kids love them!

Does anyone have a suggestion for a simple, inexpensive way to
demonstrate, or better yet, let kids experiment with, the idea that
light consists of wavelengths beyond visible light, i.e. infrared?
