Cute vid. Are kids still being taught that electrons move around the nucleus, or has secondary science moved onto the quantum understanding of electrons? That's probably a bit difficult to represent with dogs though.Have you ever used Prof Poliakoff's vids or some of the others from Periodic Videos? They've got some good explanations and explosions.
Yup kids are still being taught that electrons move around the nucleus in different levels or shells.. I haven't heard of this persons' vids but I will check them out :)
