Things to do in LA?

This is my first, I’ve been here once for a funeral, time in LA and I have some things to do. I want to go to the Peterson museum, go to the Chevy Chase skatepark, and go to the LA zoo. I’ll have about a week by myself to do these activities. Anything else I should hit? I’ve seen a ton of people go to the Griffith Observatory (I think that’s what it’s called lol) and I’ll probably do that for pictures. But anything else I should see. Also good food recommendations would be nice! TIA!

Edit: I'll be staying in La Puente and I'll have my own car so driving isn't an issue. I enjoy skateboarding and photography. I don't really want to see touristy things, even though Griffith Observatroy is touristy, and I'll eat anything. Just looking to kill time the week before my family comes in.
