In a continuation of the Life Cycles lessons in Science, Year 5 were finding out about the life cycles of birds today. They each had to examine a chicken egg. What was the purpose of each part and what was it called? Next, we broke the egg and looked at the inside and tried to identify the other parts: albumen, yolk, embryo, shell membrane, germinal disc and even the chalaza. Many children were astonished to see the inside of an egg and enjoyed seeing how complex a simple egg could be and there were many different theories that needed to be discussed and debated . Next week, they will conclude their learning as they describe how the knowledge of an egg features in the actual life cycle of egg-laying creatures.
