Re: We are scientists, not "boffins"
I think you are 100% wrong.
Kids like 'boffins' and 'propeller heads'. They want to be them.
They the like the pics of the older Einstein with the wild hair, and the white - coated lunatic professor who blows himself up for the Nth time, shrugs, and just says 'Oh well, back to the drawing board'.
If all science had to offer was stern admonitions from the likes of you to act grown up, they'd never go in for it.
They're not grown up, they're kids. The very first thing it must do is appeal to their sense of fun.
Actually, that should apply to all who do science, child or adult.
