An experiment with an egg

We did an experiment with an egg.  Miss Morgan forgot to go to the shops to buy an egg.  Oh no!  What were we going to do?  We decided that we could get some eggs from our school chickens.  What a clever idea!!
First we had to pick some silverbeet from the school garden that we could feed the chickens while we went into their chicken house to get some eggs.

 

Once we had collected our eggs we put our egg in a glass of vinegar.  Can you guess what happened?  When we checked our egg the next day we found that the shell had dissolved and the egg was all soft and squishy.  It felt very funny!
