Take the children on a guided
fantasy to the year 2050 (an example of such an activity is given in the handbook
in the section on Visioning.)
When they "return",
ask them to talk about what they have seen in pairs.
Working in small groups, draw
a mental map (this might be in the form of a chart, diagram or picture) of
what they have seen.
In the same groups, work together
to compose a letter from the future (2050) to themselves in the present, telling
them exactly what they should or should not do now to affect the world that
is in the future.
