Beyond the Human Eye: xylem. These (above) are cross sections of stems of two sycamore Acer pseudoplatanus seedlings, just a couple of weeks after germinating from a seed in spring, and already they have begun to produce woody thickening in some of their cells, visible here as the bright yellow fluorescent staining inside the stem (on the periphery of the large pith cells in its core).

Alternative abstract interpretation of still life - get students to draw cross sections of a cabbage/lettuce/orange or some other dynamic fruit or veg using watercolour pencils on watercolour paper - then reinterpret by printing the object on a geli plate in acrylic
