This innovative website explores the 21-day lifecycle of an
embryonic chick. The tutorial provides a glimpse into the day-to-day changes a chick undergoes from conception to hatching. For each day, site visitors are given a collection of great images and diagrams to examine; a list of major developments; and a wealth of information to consider. The Chickscope website also offers instructions for building an incubator and a downloadable EggMath section
