Lesson 1: Eggsploring the Egg
These materials are designed to enhance Lesson 1: Exploring the Egg. Youth will explore the idea of life cycles as they learn about different parts of an egg.
- What are the parts of an egg?
- Learning to Learn
Eggsploring Anatomy of an Egg
Download this activity to identify the anatomy of an egg.
After Dinner Science: The Squishy Egg (Activity)
Learn about the chemistry behind eggshells with this hands-on experiment.
After Dinner Science: The Squishy Egg (Recording Sheet)
Use this PDF to help youth organize their ideas and their work with the Squishy Egg activity.
Observe how to set up and complete the Squishy Egg activity.
Lesson 2: Pick-a-Chick
These materials are designed to enhance Lesson 2: Pick a Chick. Youth will explore ideas of heredity as they compare and contrast different poultry breeds.
- How do chicks in the same brood resemble their parents or each other? How are they different from their parents or from other chicks in the same brood?
Find your Flock
Explore genetics and inheritance in this game that asks youth to match baby chicks with their parents.

Lesson 3: Warming Up with Eggs
These materials are designed to enhance Lesson 3: Warming Up with Eggs. Youth will learn the fundamentals of incubation, including the importance of heat, humidity, and turning for the developing chicks.
- How can we provide ideal conditions for our chicks to grow?
- Planning and Organizing
Incubation Tracking Sheet
Egg Tracking Sheet (hatch rates)
Learn how to properly mark and place the eggs into the incubator. Record hatchability rates.
Help youth acquire the technical vocabulary needed to accurately discuss the science of embryology.
Lesson 4: Building an Eggs-Ray Viewer
These materials are designed to enhance Lesson 4: Building an Eggs-Ray Viewer. Youth will build and use a simple candler from everyday items.
- How do farmers make sure that their chicks are developing correctly?
- Relating to Others
After Dinner Science: Poultry Vision
Youth can build a working candler from everyday household items that they can use to observe how the embryo is developing inside the egg.
All about Candling Video
Learn about the history of candlers, their usage in agriculture, and how they work. The video includes a demonstration of building a homemade candler.
Lesson 5: Playing Peek-a-Boo with Embryos
These materials are designed to enhance Lesson 5: Playing Peek-a-boo with Embryos. Youth will deepen their understanding of life cycles by comparing chicken embryos at different stages of development.
- How does a chick grow?
From Embryo to Chick Video
Youth can join 4-H Agent Victoria Brewer in Chatham County, NC and the Livestock Conservancy to compare the parts of a fertilized and unfertilized egg. The video reviews the parts of an egg, shows how vinegar affects eggshells, and compares the internal structures in two different eggs. The end shows an embryo moving inside of a candled egg.
Candling Recording Sheet
This PDF can help youth record changes to the embryos in specific eggs over the course of incubation.
Youth can watch how an embryo grows from days 2 – 17 using this video of candled eggs.
Youth can watch eggs hatching after 21 days in the incubator.
If you use FlipGrid with your youth, you can ask them “What happens inside of an egg each day?” Assign youth to specific incubation days. You can decide whether to pick milestone days or to cover all 21 days of incubation. Have youth respond to the prompt as if they are the embryo. Responses should include a description of how the embryo is changing and what they expect to happen next. Youth can be creative and include the embryo’s perception of the world outside the shell.
