Mass /weight

In class we have been learning to compare the mass of 2 objects.

Blake made 2 balls of play dough  that weighed the same. He changed the shape of the balls and the play dough still weighed the same.

Milan also had 2 balls of play dough that weighed the same.She then made one ball fat and the other ball thin. When she weighed them again they still weighed the same.

       The children had to predict the mass of these 2 balls. 

Everyone said the big blue sponge ball would be heavier than the small green play dough ball............ BUT

                                 They both weighed the same!
