Eggs, Eggs and more Eggs!

May 02, 2017

     This year's embryology lesson has started!  On April 12th Mrs. Deb Kraenow from the University of Nebraska Extension Office came to Hemingford third grade to begin their lesson on embryology.  The students learned the parts of the egg and their purpose, then the students were able to crack eggs and inspect the different parts. 

     The following week on April 19th Mrs. Kraenow returned with freshly laid eggs.  The students were able to candle the eggs. (Candling is a method used in embryology to study the growth and development of an embryo inside an egg.The method uses a bright light source behind the egg to show details through the shell.)  Finally after candling, the students numbered each egg and set the eggs in the incubators.  As the students work through each process they are able to record information they are discovering.

     On April 26th Mrs. Kraenow returned and the students candled the eggs a second time. They were looking for yolkers, winners, and quitters.  Be sure to ask your student the definition of these words!  The students will candle again on May 3rd and will then remove any eggs they decide are quitters or yolkers.  By the third candling the students should be able to see some growth of the embryo.

    The students will be watching closely as our hatch date nears. May 10th is the day!
