They are learning about Jupiter in the Princess’s class. Observations from the floor as reported by Herself:
Girl from the seat behind her: Oooh Jupiter, you think you’re fancy with your 63 moons.
Teacher: Jupiter is 1,300 times the volume of earth. If you put Jupiter in an enormous bath it would displace 1,300 times the amount of water that the Earth would.
Smart (yet annoying) child: Actually that’s not true as a lot of Jupiter’s volume is made up of gas.
Incidentally, though reported to me in English I assume that this is all done as Gaeilge (at least the teacher’s interventions).
Who would be a teacher?
