Reading stories to children for example. If the story is interesting, the child will want to know how the story goes on. As soon as they can read, they will be tempted to grab that book and find out.
I'll elaborate this evening, but as a lower poster said, it is all rolling dice and everyone is certainly their own beast in their own cage. I will gladly share how it seemingly transpired (and I feel, more important, the reasoning behind focusing on such things).
In very short, I'm a huge believer that we seriously underestimate what small children are capable of understanding at you get ages, and have always felt that exposure to 'all the things' helps provide needed prospective about all that is available in life.
They have both absorbed enough surface level interest and actual information that when watching a video about a semi related subject, they find themselves referencing OTHER information they learned from another video/source and click the pieces together like Lego -- you can see their eyes light up when this connection is made in their head, and I feel it starts really showing that information across the board is solely a piece to a way way bigger puzzle, and that although learning about seemingly disconnected things in a jumble can often find itself existing the jumble and finding its place in APPLICATION in life somewhere.
This seems to really nail home the point that anything, really, may be worth learning because no doubt a real world use case may arise sometime in the future.
Again, I can write more when time allows, but that's the reasoning behind it all. We also do a ton of projects where we can actually, partially at least, use a lot of the things learned from videos and transcribe them from thoughts alone into tangible end results - beyond important for everyone of every age, IMO
