We can use balance scales to weigh objects.

Which is heavier –the cookie or the

The envelope is lighter because the envelope’s

side of the scale is up.

the balloon is bigger than the tennis ball, it is lighter than the tennis ball. We

know this because the balloon’s side of the scale is up.

turnip?

The carrot is the lightest. We know this because the

crisps?

The crisps are the lightest. We know this because the

crisps’ side of the scale is up.

Which is the heaviest – the carrot or the

banana?

They are both the same weight. We know this because

It tells us that the object being weighed which is up is lighter than the object which

is down.

heavier

If the balance scale is up, what

does that tell us?

It tells us that the object being weighed which is up is lighter than the object which

is down.

If the balance is level, what does

that tell us?

It tells us that both objects

weigh the same and are of equal

weight.

equalequal

For example, this cookie weighs the same as 5 cubes.

We can use other objects to

describe and compare the

weight of objects.

How many cubes does this

strawberry weigh?

The strawberry weighs the same

as 3 cubes?

How many cubes does the cupcake

weigh?

The cupcake weighs the same

as 6 cubes.

We can use other objects as units of measurement such as pencils.

The cupcake weighs the same

as 4 pencils.

We could use rubbers as units of measurement.

The cupcake has the same mass as

6 rubbers.

What would happen if we took one cube away?

The chocolate bar would go down and the cubes would

go up.

The chocolate bar is now heavier

than the cubes.

What would happen if a cube

was added?

The chocolate bar would go up and the cubes would

go down.

The cubes are now heavier than the chocolate bar.

Do we need to have more or less cubes to make the

scales balance?

We needed to have less cubes to get the scales to

balance.

Do we need to have more or less cubes to make the

scales balance?

We need to add more cubes to

make the scales to balance.

The mass of the torch is greater

than (>) the mass of the battery.

Which is heavier –the battery or the

torch?

The torch is heavier. It weighs

5 cubes. The battery is = to 3

cubes.

Which is lighter –the egg or the

toast?

The mass of the toast is less than (<) the mass of

the egg.

The toast is lighter. It weighs 2 cubes. The egg weighs 3 cubes.
