In an opportunity provided through Cornell Cooperative Extension, fifth grade students at Warren Street recently participated in a hands-on chick embryology science project with Mrs. Ferrari and Ms. Morreale. Students were able to document the process of how a chicken develops in an egg, from start to finish.
Over 21 days, students tended to 18 different colored eggs, making sure they were rotated and consistently kept at the correct temperature to mimic the incubation process.
Students documented the various stages of chick development and growth by using a bright light to show details through the shell — a process that is called “candling.” Using the candling process, students could observe blood vessels, the formation of organs, wings, a beak, legs, bones, feathers, and eventually the egg tooth which helps the chick emerge from the egg. Data was recorded daily, including the student’s observations and measurements, and the weight of each egg.
The students extended their knowledge and understanding of the project by engaging in egg experiments. They also displayed and shared all of their findings and data on colorful bulletin boards through charts, graphs and drawings, and created a special video diary.
