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.

Who knew that a virtual journey through the human digestive system could be so fun and informative? This educational website created by Teach Nutrition--a group of Ontario-based dietitians--features two great, interactive games. The first game, Digest Quest, was designed for fifth-graders and takes students on a journey from the mouth to the large intestine via the esophagus, stomach, liver, pancreas, and small intestine. In this video-game-style tutorial, travelers brave the dangers of the digestive system while answering questions, and learning about the functions and structure of the digestive organs. The second game, Stretch Your Noodle, was designed for seventh- and eighth-graders and treats students to a dynamic, nutrition-focused quiz show. Both games come with teacher information and resource sections, and Stretch Your Noodle is available in both French and English versions. [NL]
