Comparing Mass

These images are not shown to the same scale. An elephant is much bigger and heavier than a cat or a car. Can you arrange these things in order from lightest to heaviest? Can you estimate the mass of each of these things?

How many oranges do you think you would need to balance an elephant in the scales?

Now try matching the list of objects below to their masses.
