Egg-citing Eggs-periments

To kick start our Science term Mr Anderson had us all in fits of laughter and on the edge of our seats at Monday meet up as he got us using our science skills to establish that eggs are pretty fragile and breakable. He demonstrated this by dropping eggs on the stage and sure enough they broke very easily.

Then Dustyn and a few other helpers were invited up on stage to try and break an egg by squeezing it as hard as they could in their hands. But this time none of the eggs broke. The children hypothesised that maybe the eggs were fake but Mr Anderson then broke more eggs by dropping them on the stage again. Hmmm why didn't they break?

Then we predicted whether the eggs in the trays on the table would break if someone walked on them. Everyone thought they would. So Mr Anderson got a small new entrant to walk across the eggs. Guess what? They didn't break! We reasoned that maybe it was because he didn't weigh much so we tried the experiment again with a bigger child but they still didn't break!

Then we thought that surely an adult would break them if they tried to walk on the eggs. So up came Kiri from Kahukura and she walked across the eggs - and still none broke! Hmmmm why didn't they break?

Declan and Tom from Kohara tried the experiment at home. They also managed to walk across the eggs without breaking them!

Why do you think the eggs didn't break?
Can you make a hypothesis (theory or guess) about what happened?
