I’ve been thinking about how to teach the size and proportions of the solar system to my kids, I’ve bought a couple of packs of blank RFID cards on which I intend to paint the planets over a starred background. And then walk with my kids the meters necessary to cover the distances before displaying them. What I don’t know is if there is a clever way to use the RFID tech, this website kinda offers an idea.
