To celebrate the International Year of Light why not make a craft that lights up. You could pair these up with a discussion of LED bulbs and how much more power efficant they are then incandescent or even fluorescent bulbs.
Instructables can be a great source for craft ideas with a twist. Here are 4 LED crafts from that site.
LED Pipe Cleaner Bracelet are easy enough that even a Spark could make them.
LED Critters are only a little more difficult then the braclets and are easy to deactivate for storage.
Glowing Critters – these do require the use of a glue gun to ensure the craft supplies all stick to the plastic egg, but I love that every girls critter would look completely different.
These LED Buildings are made using copper tape to build a circuit.
