How to Calculate and Measure Mass and weight

Different objects have different capacity. Capacity is the quantity of liquid a container can hold. You can compare the capacity of one container to another.

Below, this tub has the capacity of 5 bucketsful. This implies that the capacity of a bucket is less than the capacity of a tub.

So a container can be half, twice or many times the capacity of another container.

Activity 1: Find 5 different containers and compare the capacity of each.

Measures of mass:

1 kg = 1000 g
