We received these
from Christian and Kodai from the Munich
International School, though I don't think the graphs should have
ever become horizontal.
It is also worth noting that the graphs didn't always take
into account the varying widths of some of the containers - e.g.
when the water reaches the narrow top of the volumetric flask, how
will the height of the water level be affected by an increase
in the volume of water?
We also received good sketches from Priya, Stephanie and
Aishwarya, also from the Munich International School.
