A sure sign of spring is hatching out chicks. Mrs. Klingman’s students are learning about life cycles through a hands-on project and physically watching the transformation of an embryo to a chick. The students have been able to explore and learn all about the life cycle, a vital curriculum in this grade level, through the world of feathers.
We started our study of a chicken's life cycle on April 12. It takes 21 days for a chick to develop and hatch. When we first put the eggs into the incubator, students made a scientific hypothesis: how many eggs will hatch and how many will stop developing? Students have been waiting patiently and observing the eggs daily.
In addition to learning about the growth and development of the chicks, students were able to apply their skills in measurement and recording data. We have had to monitor the incubator to make sure the temperature stays at 99.5 degrees Fahrenheit. Also, we needed to check that the humidity was stable at 45-50 percent for days 1-17.
The incubator was a self-turning one, and on day 18 we stopped turning eggs to prepare for hatching. At Days 7 and 14 we candled the eggs to see if they were viable.
On Day 20 the eggs started to hatch! We hatched three that afternoon and then on Day
21 we hatched 11. When we came in on Day 22, there were two more chicks. We are patiently awaiting the hatching of a couple more chicks.
Throughout the 21-day hatching project, students also cultivated a deeper and more personally meaningful connection to what they have learned about life cycles. Bringing this experience into our classroom has truly brought our third graders’ learning to life!
