What's Inside an Egg?
4/20/2018
Our Egg unit has begun! We started off our unit with the investigation "what is an egg?" And we had lots of questions about what was in an egg. Together we did a class dissection of eggs. Ms. Bookman helped us through our dissection and we learned that there were more parts to an egg than we thought! By the end of the activity our explores were able to identify the shell, the shell membrane, the albumen (egg white), the yolk, the protein chords (which hold the yolk in place), and the small white dot that is where an embryo would grow. I was so impressed with how the explorers investigated and asked questions. Eggs are a wonderful topic to study. But they can also be tricky in that eggs are fragile and therefore hard for preschoolers to explore on their own. Doing an egg dissection lets students explore and learn and wonder and answer their own questions in a integrative way, being both student-led and teacher guided. After watching Ms. Bookman and myself model egg dissection and show all the parts, each student got a chance to crack their own egg. Some students carefully inspected each part with a single finger, others attempted to pull apart and separate all the egg parts, and others dived in with two hands wondering about the textures and what happens when it is all mixed together. Also, most exciting this week, we started incubating chicken eggs! We began egg journals and a countdown chart. We are all super excited to see and hold the baby chicks when they hatch. In our excitement, the explorers have been playing lots of egg and hatching games. Next week we will learn which animals lay eggs. A Volcanic Eruption The exciting end to our recycling study!
