I am a member of the Institute of Electrical and Electronics Engineers (IEEE). They’ve just come out with a brochure designed to inform 11-13 year olds about engineering careers. I think it’s notable because it’s so simple, yet gets the message across. There’s a short news item about the brochure on the IEEE website. You can also download a PDF version the brochure. They do list amateur radio clubs as resources to help kids find out if they might like engineering.
Overall, I think this is a good example of how to design something that would appeal to kids.
