This session generated a lot of talk and interest because it's pretty practical. You will need hen's eggs (one between two children), bowls to crack the eggs into, and forks to burst the yolks, as well as a Secrets of the Egg sheet for every student. I treated my group to some quail's eggs too because they're so pretty - I boiled them first to make them more robust, but the shells are still fragile so they need to be handled carefully.
The warm-up exercise was supposed to be five lists - twenty seconds each to see how many items they could write down under a heading, and then a quick sharing of ideas. However, I only did four lists in the end because I decided there was no need to do the one about hidden things.
After that I simply followed the lesson plan above. I didn't let the children share their ideas for each line until the whole poem was finished, but you could if you preferred. I was very pleased with the results which can be seen here. The children range from Y3 to Y6.
