This week we pick an activity from a vast website, with material in all sorts of subject, and not only in math and science.

This activity introduces young children to the concept of configuration spaces and to the subtleties of concepts which we sometimes take for granted, such as “dimensionality”, as soon as we are adventurous and play with spaces beyond our familiar and tame differentiable manifolds, with local affine space structure that glues nicely.
