The Mars
Colony lesson challenges the common student idea
that science knowledge is an unfolding catalogue
of correct answers. Students are asked to look at
a broad question “What is it like on Mars?” and
to answer that question using information available
to a previous generation of scientists. They should
discover that the “wrong” answer of 100 years ago
was sensible and reasonable at the time. Scientists
make the most of the information they have.
The possibility exists of linking this lesson to
the creative writing of some of the greatest science
fiction authors of the past 2 centuries, since HG
Wells, CS Lewis and Jules Verne all wrote wonderful
books on this very topic. |

Observable
from earth by just looking up!
Mars is a planet, not a star. It moves across the
star patterns. Mars is a reddish colour.
Does not need an instrument but needs
much more study and thought
Mars travels around the sun in a circular orbit.
Needs a telescope to see
Mars has two tiny moons. Mars has a day that is
a similar length to Earth’s. Mars has “ice-caps”.
Needs a great telescope or a space probe
Mars has a thin atmosphere. Mars has a huge volcano
on it. The “ice cap” on Mars is made of Carbon dioxide.
Mars has an average temperature similar to a freezer!
Needs a robot lander
Mars has a sandy surface. Soil samples have not
shown any signs of life. |
The
exact order isn’t important…simply the idea that
knowledge is developing over time. |
