A note came home today with my daughter's half-term homework assignment. I was pleased to note that it was about science, but less happy that it did not appear to have been thought out properly. The task was to make a 3D model of the solar system - fair enough - but the teacher took the trouble to include a chart listing the relative sizes and distances of all the planets (including Pluto, but I won't quibble about that). She also suggested using cocktail sticks to show the planets orbiting an orange Sun (literally an orange), and constrained the maximum size of the model to 60cm across.
I had to point out that if the Sun was represented by an orange of, say, 7cm in diameter, then Pluto would need to be a mere 0.1mm across, and fastened to the orange by a cocktail stick of length 297.37 metres. I don't believe this is what was envisaged.
