I'm a middle class white male, so idk much about these things. But my first idea was to put phrases like, "Did you know the first computer programmer was a woman? Ada Lovelace" and other surprising, encouraging facts about women, minorities, and inclusivity in STEM on posters, flyers, or whatever.<p>I think one of the keys to getting anyone (child, high schooler, adult, etc) interested in something is to make it cool. Making something cool requires a different approach for different groups. Adults might think it's cool to make a lot of money, but kids often don't care about that. But if you know anything about your child's generation and what her age groups thinks is cool, try to find facts that highlight how "cool" STEM is in their context.<p>Please don't interpret my use of "surprising" to be condescending, I mean that I think most high schoolers will find these things surprising.
