\label{fig:ice}  Example student work from the ``Understanding and Reducing CCD Images'' lab, in which students illustrate different phenomena in CCD images using ice-cube trays and confetti. Here, a student illustrates and describes a saturated  CCD image of asaturated  star. The ``imperfection'' at right was added by the student to illustrate that the background is not uniform and needs to be flat-field corrected.
