Your story is sadly something I have seen a lot in my daughter's eight years. I also have some horror stories of ex-in-laws in Texas and their pageant mommery (ugh, shivers).
I need to get back to blogging in general as I think there are plenty of anecdotes worth sharing of science & tech parenting and startup life.
Sounds like you're on the right track already.
The main thing is to answer questions honestly - even early. Don't feel you have to coddle or dumb them down too much. When I explain things I use scientifically accurate (though obviously simpler wordage) explanations. I talk to her about the wonder of science and its explanatory power. They're way more sophisticated in their thought processes very young than popular culture would have you believe and they're eager to learn.
I got the telescope while she was young and she marveled at the details on the moon (craters, rough edges), and how many more stars you could see. The microscope didn't capture her attention (not yet anyway) so I don't push it.
The solar eclipse was a great excuse to break out pinhole camera-ing and there's a great photo of her holding a piece of paper with the light disc of the sun on it with a big dark chunk bitten out of it by the moon. Took her to NASA for the transit of Venus so she got to see it through high powered cameras of enthusiasts.
Then mostly just followed her interests.
She had a couple of ideas for "Dad wouldn't it be good if..." websites/services. So I've promised her next hackathon that comes up she can come, and Daddy will build the product but she has to be the PM and tell me what goes where and how it works, and we'll practice her presentation in advance and she can be on stage to do the pitch (and if she backs out and gets anxious she doesn't have to, that's okay, because it's not about forcing her to do something if she doesn't want to).
Realized this is becoming a very long answer, but that's basically how I am dealing with it.
