A curious thought and one which we all enjoyed mulling over during the week. Dinosaur eggs, ostrich eggs, chicken's eggs and a small nest. Those items joined our circle this week.
Our parents are simply wonderful! In a timely manner one lovely mum brought in a bird's nest and we all got so much out of having it here. The children all concluded the nest would have been built by a small bird for a small bird and small chicks as it was so small! And as further proof they spotted a 'teeny weeny dip' in it which would have fitted an egg.
We compared the size of eggs; we used an appropriately sized pom-pom to represent the egg that would have fitted in our nest. We then placed that next to the chicken's egg, and then the ostrich egg, and finally compared the size of our cut-out template of a dinosaur egg. This made us think about the thickness of the egg shell, and how it was related to the size of the bird / dinosaur in the egg. One girl postulated that if a tiny bird had the egg shell of an ostrich, it would have ended up living in the ostrich egg all their life as the shell was too thick to break through.
The dinosaur egg was 30cm tall and, my resident dinosaur expert, said it must have been from the Argentinosaurus or the Gigantosaurus. I suggested that in actual fact it is was the size of egg from a Titanosaurus and he corrected me, saying the name was simply 'Titanosaur'!
We learned how they laid several eggs at a time and one of the boys said 'I think they laid hundreds!' Which in their life-span and was spot on!
When I asked the question why so many eggs were laid at once and, how come not every egg hatched, one girl was quick to suggest that the eggs were eaten by other dinosaurs.
There ensued conversations of how do we like to eat our eggs...
' I like it fried so it is really crispy.'
'I like scrambled eggs.'
'I like the yolk being hard.'
'I like egg mayo.'
'I like eggs made from chocolate.' No disagreement there! She won that debate!
