Comparing Weight and Capacity

In maths this week, we are exploring the capacity of different containers and the weight of different objects. We are finding the heavier and lighter of two objects by using balance scales and feeling the objects in our hands.We are exploring how objects small in size can be heavy and how some larger objects can be lighter than a smaller object. We are making our own predictions first and having lots of discussions. 
We are also comparing and ordering different containers according to their capacity.
