Created as part of Chickscope--a collaborative project between researchers and educators at the University of Illinois and Central Illinois school teachers--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, a downloadable EggMath section (reported on in the NSDL Scout Report for Math, Engineering, and Technology, August 29, 2003), and an MRI Database with over 2000 magnetic resonance images.
