Glad to hear so many people are clear on the behavior of electrons.

Two atoms are walking down the street and bump into each other.

"Are you OK?" asked one.

"I think I lost an electron."

"Are you sure?"

"I'm positive."

Are you teaching systems*, or are you teaching facts about electricity when a comprehension of electron behavior is, for the most part, above the level of 4th graders? It's true, kids at this age love building circuits, seeing the bulb turn on, etc.. It's a fine line between learning the names and parts of things, and walking away with misconceptions about what is really happening.

* How all the inter-related parts of a circuit are necessary in order for the whole thing to work, etc.

I think the unit (and electricity is a unit of study in many science curriculu, certainly it is in MD and VA, both in 3rd or 4th grade I believe) is intended to be an introduction to the concept of electricity, not aiming for total comprehension as an adult or high school student would understand the concepts. For that reason, the students would be expected to revisit the unit at a much deeper level both in middle school science, and high school physics.

Same as US History is taught in elementary school, in an age appropriate way, but is taught again in high school. (And college for that matter!)
