Geeky(or knowledgable)parents - what off curriculum learning have you done with dc?

[StumblingOffTheRocks]

We’ve done some astronomy stuff. Looked at stars and constellation and found out about star link satellites.
Gone through some coding projects and did some science experiments involving bubbles and learnt some stuff about plants guided by a Crest project.

Are there any resources you can recommend?
Ideally, I’m looking mostly for things the dc can just get on with by themselves though I don’t mind spending some time.

I've been putting on some of these sign language videos if that counts?

Fab idea to learn sign language. Thanks.

Ive come across a book and a course that teachers children to be financially smart that is actually really good. My dd has been lapping up it up which I never thought would happen. Quite cool really

You could try TinkerCAD for 3d design. My DS really likes it and he's geeky. (Don't know much about it personally, though.)

we did a day on the fibonacci sequence which included maths, art and biology. dc loved it. but we are mostly sticking to the school set work.

Cambridge Uni Astronomy have an amazing set of lectures on YouTube that my kids adore so far, really mind blowing stuff. I ought to leave them to it and get on but actually it is fascinating and I end up on the sofa too..
