The presenter defines mass as the amount of matter contained in a particular object. He further explains the machines used while measuring mass and the different units used such as grams (g), kilograms (kg) among others.
By the end of the clip, a pupil should have learnt converting from one measure of mass to another such as kilograms to grams and vise-versa. Also, a pupil should be able to add and subtract mass given in different measure units.
