The book sounds like an excellent idea. Besides catching figures and
elementary-level text on each page, may I suggest also "sidebars" or boxes
for the benefit of teachers and parents, to help generate inter-generational
discussion, that could be a bit more technical, and perhaps include
references to (somewhat) more advanced material. You may also wish to
intersperse questions (with answers at the back) that needn't repeat what is
otherwise presented, but lead the curious mind further.
