Compare the longest travel
made by today's pupils with those of their parents and grandparents,
when they were at the same age.
1. Ask the pupils to gather
information about the longest journey (from - too) and the means of
transportation in the three generations. Put up three maps in the classroom
where all students draw the longest journey of their own, their parents
and grandparents.
2. It is possible
to follow up the visual impressions by calculating the changes in
energy consumption
and Carbon Dioxide (CO2) emissions over generations,
for each family or class average (a typical family) by using the following
key-figures:
Energy
consumption and CO2 emission from transport
