"I didn't know eggs could be this interesting."
Peep! Peep! Peep! We have chicks! It’s been very exciting to watch the chick peck a small hole in the egg and work and work and work to get out of the shell! We have seven chicks thriving in the “Chick Condo” we’ve set up in our room We all enjoyed watching the chicks explore on carpet as we sat in a circle around them. We'll all get a chance to hold next week when they are little less fragile.
We continued our egg challenge on Monday by performing some egg-citing eggsperiments. We began with dissecting an egg. We described and wrote about how an egg feels and looks. We used magnifying glasses to help us explore the outside of an egg. We cracked eggs open and we found the following parts: yolk, white, white spot, shell, shell membrane, air sac, and chalaza (white ropy part). We learned about the purpose of the different parts and drew our observations. We have been learning about how a chick develops in twenty one days. We read Egg to Chick, Bird Beaks, and Eggs and Baby Birds to name a few. We labeled the parts of a developing chick.
Our next eggsperiments dealt with the strength of the egg. We predicted what we thought would happen if we squeezed an egg as hard as we could. Most of us thought that the egg would either crack or break. Much to our surprise– we could not break the egg by squeezing it. (If you try this at home, take off your rings. Be careful to wrap your hand around the egg, as if you were trying to enclose the entire egg in your hand. It’s easy to poke your fingers into the shell, but difficult to crush by squeezing.) We decided that this surprising strength would help keep the growing chick safe while its parent sat on it.
Finally, we took four eggs and set them up in modeling clay so they would stand up. We predicted how many books we thought the four eggs would support before crushing. Most of us had predictions under 10. Again to our surprise, we were able to stack 33 books on the eggs for a total of 53 1/2 pounds before the eggs broke!! It occurred to us, many first graders weigh about 54 pounds and we did try to repeat our experiment by placing one book on the four eggs and then placing a first grader on the book. Not quite as successful, the eggs held for a brief second before splatting…such is the nature of science!
Thanks to all who came and help chaperon our field trip to the Jordan Greenhouse. It was a lovely day for a walk. We saw all kinds of interesting plants! Some of our favorites included the sensitive plant, banana, pineapple, Venus flytrap, cacti and monkey dinner bell tree.
All student library books are due back before May 1th. Please help your student round up any books they may have to return to our library.
Have a great weekend!
Where were you last night? We took a very long and interesting walk.
