Added big-list tag, seems appropriate as there are over a dozen answers.

| Nov 3, 2020 at 10:04 | comment | added | mlk | With regards to the Gauss-Bonnet theorem, there is a beautiful proof for the special case of triangles of a sphere, which I think is indeed suitable for all ages and likely what your predecessor did. You just extend all three sides into half circles, each in the same direction, e.g. clockwise. You then get two copies of the triangle and three "fat orange slices", whose opening angles are complementary to those of the triangle and whose area is proportional to those angles. Knowing the area of the sphere then gives you the theorem. | |

| Nov 2, 2020 at 17:03 | comment | added | JP McCarthy | I am surprised nobody has mentioned the Hilbert Hotel. Another talk maybe the chaotic nature of the logistic map or maybe even explain how we cannot predict weather beyond a few days... another talk would be interactive with möbious strips and such. | |

| Nov 2, 2020 at 9:09 | comment | added | Pietro Majer | In 15 minutes I would reduce the introduction to a couple of sentences ("you can already do your mathematical explorations because you do not need pre-requisites from other sciences, and you do not need a laboratory"). And I would focus on one topic, for instance n-dimensional geometry may draw young and old students | |
| Nov 2, 2020 at 8:28 | comment | added | Martin Sleziak | This reminded me of this older question: “Mathematics talk” for five year olds. The topic is different from this question - but since it has many answers, maybe in some of them could serve as an inspiration for something which could be adapted for your needs. | |
| Nov 2, 2020 at 8:07 | comment | added | Solveit | Ah I see that you are actually a professor of economics that... writes papers on algebraic K-theory?? Well, that's definitely not a career I knew could exist, and the adult me would now also like to hear this hypothetical talk. | |
| Nov 2, 2020 at 8:02 | comment | added | Solveit | Perhaps tell them that studying mathematics can be a career and talk about what it's like. When I was nine, I certainly didn't know that 'mathematician' was a job that you could get. I knew that mathematicians existed, of course. But somehow I didn't manage to make the connection until I was already in high school. | |

| Nov 2, 2020 at 7:06 | comment | added | KConrad | If you want to do the 2nd item in your list, start by asking what the students like about math and then share what you like about it. That would be more interactive than a straight lecture. An alternative is to show them math has unsolved problems (e.g., $3x+1$), which younger students may not realize, or give examples of mathematical patters that can go on for a while before they stop working (old MO questions are on this, though you'd have to pick examples carefully) in order to illustrate the difference between what makes results accepted in other experimental sciences compared to math. | |
| Nov 2, 2020 at 5:47 | comment | added | Steven Landsburg | @AlexandreEremenko: I actually have at least a partial vision of how to do this in a way that's honest and comprehensible (but of course omits details). What I'm unsure of is whether I want to pursue this vision. | |
