This is Nebraska Extension in Lancaster County’s initial presentation given in local classrooms as a part of the 4-H Embryology school enrichment program. The presenter explains what Embryology is (i.e. the “study of” + “embryos), what fertilized eggs need to properly incubate (i.e. heat, humidity and turned three times a day), as well as the parts of an egg. After answering students' questions, the presenter normally places a dozen fertilized eggs in the classroom incubator!
You may watch eggs hatch on 4-H EGG Cam at lancaster.unl.edu/eggcam!
Locally, the 4-H youth development program is a partnership between Nebraska Extension and Lancaster County government. Learn more about the Lancaster County 4-H program at lancaster.unl.edu/4h.
