This 49-page 4-H guide to embryology provides background information and experiential life science activities for use in the elementary classroom. Students learn the parts of an egg, classification of chickens by breed, how to use an incubator, candle an egg, build a brooder, and more. Each activity is correlated to national science standards and follows the five steps in the experiential learning model: experience, share, process, generalize, and apply.
