Each issue of CIRCA comes with a FREE 4-page booklet of Teacher's Notes.
These show the content, levels, answers and, where appropriate, additional
information on a topic with suggestions for further work. There is also a reproducible
worksheet which is often a starting point for a wider investigation.

20 000 leagues under
the sea
In the book 20 000
Leagues Under the Sea
by Jules Verne, as well
as a giant squid and the
eccentric Captain Nemo,
we meet nautical
measures (shown
below). Pupils can work
out metric equivalents.
What other books and
stories provide different
measures?
League: a measurement
of travelling distance of
about 3 miles (no official
metric equivalent). The
kidnapped Professor
Aronnax travelled 20000
leagues under the sea
in Nemo’s submarine
Nautilus. How far did he
travel in kilometres? The
submarine did an
average of 30 knots,
how long did it take?
Fathom: 6 ft (the span of
a sailor with arms
outstretched) used for
measuring depth of
water.
Cable: 600 ft (100
fathoms) used for
measuring a ship’s ropes.
Nautical mile: 6080 feet
(1.852 km) is 1/21600
of a great circle (Earth’s
exact shape causes
variations) which is
1 minute of latitude.
Knot: speed of boat or
aircraft as nautical miles
travelled per hour.
(Originally a knotted
rope, called the log-line,
was let over the side of
a ship and timed with an
hour-glass.)
