20. THE TIME CAPSULE
In Primary school we
built a “time capsule”;
a box where children
put some agents by
which global warming
is caused
After that the box is
deposited in a secret place
in the school to be opened
in the future.

Every pupil is given a
planet and they have to
do “planetwork”
cleaning, recycling… in
order to their planet
become bigger
Help us to understand
