Incubating and hatching chicken eggs in the classroom is a hands-on learning experience you can use with students from kindergarten to 12th grade. Classroom experiments with chicken embryos can help you teach complex systems such as nutrition and the circulatory system, or more basic skills such as data measurement, collection, and analysis. These projects help students learn biological concepts and develop a deeper understanding of the life sciences. Examining embryos at different stages of growth, and observing a beating heart are just two of the projects you can use. The guide includes test questions and key.
