Egg-citing Eggs!!

by Mrs. O'Rourke's Class

Excellent Eggs!

by Olivia, Audrey and Cameron

On April 18th we got eggs! We got 7 chick eggs and 3 duck eggs. Mrs. O’Rourke wrote numbers and letters on the eggs. Mrs. O’Rourke wrote with a pencil because if she wrote in pen the ink would go inside the eggs. The duck eggs were light green and the chick eggs were different shades of brown. All the eggs have a number and a letter.

FUN FACT:

Roosters, Hens, and Chicks!

by Shoshana, David and Monty

These are some fun facts about chickens. Chickens are birds. Roosters are males, hens are females, and the chicks are babies. A rooster says cock-a-doodle-doo! A hen makes the cluck sound! A chick says cheep! Chickens live together in small groups called flocks.

Incredible Incubator

by Jessica, Karina and Mark

Do you know how the incubator works? This is what happens in the incubator. The incubator keeps the eggs warm. We put water in the incubator because the air needs to be moist. The incubator turns the eggs because they have to be kept warm on all sides. The incubator takes the place of the hen and helps the eggs to hatch. We are happy that they are hatching.

  

All About Temperature

by Alessia, Patrick and Antonio

The temperature of the incubator is very important. The temperature of the chick incubator is 99.6°F and the temperature of the duck incubator is 37°C. We used a thermometer to tell the air temperature. If the temperature is not right, then the embryo will not develop.

Candling For The First Time!

by Campbell and Peter

 

HOW TO:

Find Out How to Candle

by Liam, Sebastian and Ama

Do you know how to candle? We’ll tell you how. You need a film projector or a very bright light to see if the embryo is developing. You need a dark room and you have to hold the egg to a light and look for shadows.

We are going to talk about when Mrs. O’Rourke’s First Grade class candled the eggs for the first time. When we candled the eggs we saw blood vessels, the shadow of the embryo, and the air bubble. We used a film projector to candle the eggs. We candled in the closet because it was dark.

Candling The Second Time

by William, Aidan and Michael

We candled the eggs a second time. The blood vessels got thicker, the embryos got bigger, and the air bubbles stayed the same. Six chick embryos and two duck embryos were developing. One chick egg and one duck egg did not develop. We are excited that the chicks are hatching.

Eggs Are Not Just Food

by Tommy, Joe and Austin

We noticed eight parts inside the egg. The parts of the egg are the yolk, air bubble, shell, membrane, bigger membrane, chalaza, albumen, and egg cell. The inner membrane helps keep the yolk from leaking. If the chalaza is split, the yolk will float. Sometimes the egg stops developing because the inside of the egg doesn’t work. The closest membrane to the shell helps keep everything inside. The yolk is food for the embryo. The albumen is a cushion for the embryo. The shell protects the embryo. The egg cell is where the chick starts to grow. The air bubble has air to the pipping chick.
