\label{fig:ice}  Example student work from the ``Understanding and Reducing CCD Images'' Lab, where lab, in which  students illustrate different phenomena in CCD images using ice-cube trays and confetti. Here, a student illustrates and describes a CCD Image image  of a  saturated 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.
