Question:
How does electricity work? All the books I found in the library are for bigger kids.


Replies:
Graham,

I cannot explain electricity completely without getting like the books for bigger kids. However, I can explain a simple circuit. It is not all of electricity, but it is a place to start.

Consider a battery connected with wires to a light bulb. The battery has chemicals inside that push electrons through the wires and bulb. The wires that connect the battery to the bulb are wide enough to let the electrons flow with no problem. The wire inside the bulb (the "filament") is very skinny. Many of the electrons crash into filament molecules very hard. This makes the filament hot. When something gets very hot, it glows. This is how a battery uses electricity to make a bulb glow.

A good question deserves a good answer (or at least a good try for an answer). I did a web search on the term: < electricity grade K-5 > on www.google.com and found the following "hits". The quality of the "hits" varies, and some are more aimed at a teacher, rather than a student. However, with the help of your teacher this should give you a start. Some "hits" also have other "links" which I did not track down.
