We've had a series of relatively clear evenings lately, so I have been getting out regularly to watch the disk grow and the crescent shrink as Venus passes between us and the sun. I think I first did that nearly 50 years ago, and haven't had (or taken) the opportunity to watch it in quite a while. A couple neighborhood kids stopped by when I was out last evening, and I had a hard time convincing them that what they saw in the telescope was really not the Moon. I think that by the time they left, they understood why the Moon and Venus both have a crescent phase (one of them finally said, "Oh! Because it's night there."), and had a better grip on the layout of the solar system and how we understand that. They had learned about it in school, but this was a case where they could actually SEE it, and that makes it a lot more REAL.
