## Mass

Year 2 have been learning about mass. Mass is a measure of how much matter is in an object – how heavy something is. The more mass something has, the heavier it is.

Year 2 have been finding the mass of different objects by hefting and using balance scales.

Hefting is when you hold objects to estimate or test the weight of objects.

Take a look at the photos below.

What have you enjoyed while learning about mass?

Can you use ‘heavier than’ or ‘lighter than’ in a sentence in a comment below?

My name is Ashley Azzopardi and I teach a Year 2 class in Sydney, Australia.

Dear Year Two,

I would like to share with you that I liked using the balance scales to weigh objects, like the smart board pen and a candle. I also liked estimating how lighter or heavier an object is compared to another object through hefting.

Kind Regards,
DI

Mass tells us the weight of something. The bowling ball has more mass than the little toy. 2 things the same size can be different in mass, like a melon and a balloon. I also liked hefting using balance scales!😀

I like that you were hefting at home! Great work.
