Josh Faber, an astrophysics postdoc at Urbana-Champaign, is looking for ideas. He is working with the Orpheum Children’s Science Museum on projects for an upcoming Einstein day to be held in the fall. They are looking for ideas for hands-on demonstrations that would help teach young kids about various ideas from Einstein’s work (relativity, photoelectric effect, whatever). The idea, as I understand it, is that they are really looking for demonstrations, not just some paragraphs of text. I think that being metaphorical is okay (such as the old chestnut of a curved rubber sheet to represent curved spacetime), but the underlying scientific concepts should be correct.
Leave suggestions in the comments. Let’s see if anyone can come up with anything that makes it into the museum.
