Abstract	We describe a technique for removing and growing chick embryos in culture that utilizes relatively inexpensive materials and requires little space. It can be readily performed in class by university, high school, or junior high students, and teachers of any grade level should be able to set it up for their students. Students will be able to directly observe the chick's development from 3 days post-fertilization to the point at which it would normally hatch. Observing embryonic development first hand, including the chick embryos' natural movements, gives students a full appreciation for the complexity and wonder of development. Students can make detailed observations and drawings, and gain understanding of important principles in developmental biology. Finally, we suggest various ways in which this project can be adapted to allow students in advanced classes to design and implement their own projects for investigating teratogenic effects on development using the ex ovo model of chick development.
