Here are two marbles, one made of glass (red) and
one made of steel (gray). The marbles are the same
size, but the steel marble is heavier.
The steel marble is heavier than the glass marble, but both marbles
will sink if placed in one of the cylinders. We are going to put
one of the marbles into a cylinder:
With the glass marble inside of it, the water level
in cylinder 1 has risen to 7. If we now put the steel marble
into cyliner 2, to what level will the water rise in cylinder 2?
less than glass: less than 7
same as glass: 7
more than glass: more than 7
Explain why you predicted the result above:
