Looking for Tips on how to introduce the tech/computer world to kids

Hey everybody,

I'm in college and I have a younger sister who's 10. She doesn't have a phone yet (our parents are kinda strict) but keeps asking me to teach her about the Internet/tech stuff. She's pretty young though and there are obviously lots of parts of the Internet where kids aren't safe, plus some tech stuff (especially coding) is too hard for kids. Basically, I'm wondering if any of you have experience with introducing kids to that world, and if you have some tips for me.

Appreciate it,
