We all know eggs are very fragile, right? Today we did an experiment to see just how easily they break. First we emptied the egg and cleaned out the shell. We drew a line aroung the egg and then broke the shell off down to the line. We had to be extremely careful because the shell was very easy to break. Once we had four eggshells ready we placed them on the tray and started loading books on top of them! We were pretty sure they would break but we had THIRTEEN books stacked on top of the eggshells before the first one cracked. Eggshells were much stronger than we realised so the wee chicks inside are kept safe. We also found some building structures that use domes and arches to give them strength.
