Neighborhood children plot the movement of the earth around
the
sun, and the changing seasons.
Plot the earth as it moves
around the sun in 365 days, plus one-fourth day, to complete a calendar year
(and a leap year every four years); divide it into four phases or seasons:
spring, summer, autumn and winter in this order. And while
the order is fixed, the occurrence of the seasons in the
Northern Hemisphere is exactly the opposite in the Southern
Hemisphere.
Plot the earth as it moves around the sun and mark the longest day (June
21), longest night (Dec 21), and call them Summer Solstice and Winter
Solstice, respectively - that is, if you live somewhere in the Northern
Hemisphere. In the Southern Hemisphere it is winter when it is summer in the
north, summer when winter, and Spring and Autumn are interchanged.
Plot the earth as it moves around the sun and mark two dates when day
is equal to night: Spring Equinox (March 21) and Autumnal Equinox (Sept 21) -
whether you live in the Northern or Southern Hemisphere. These dates are
significant to some leaders: "Beware at the ides of March." (Warning before the
assassination of Julius Caesar), and the Declaration of Martial
Law in the Philippines by President Ferdinand Marcos.
Plot the earth as it moves around the sun and know when the rains start and
ends (habagat), when the rice fields are about to be harvested and when
the cold Siberian winds blow in (amihan). And in
between, a brief hot and dry summer that allows the land to rest (fallow), and
children to take a vacation from school.
Plot the earth as it moves around the sun, and study the relationship of our
planet with other planets, the nature of its orbit - apogee and perigee - as
these affect our climate and the living things on earth. In fact,
the realignment of the planets is full of speculations and prophesies
regarding the end of the world.
Plot the earth as it moves around the sun and imagine how the sun's energy is
harnessed by plants by means of photosynthesis,
how differential heating causes
wind, storm, and severe winter, the movement of air and ocean
currents that redistribute heat and cold. Or simply to witness the
passing of night to day at different proportions and schedules.
Plot the earth as it moves around the sun and know it by heart as the calendar
of school and office, of work and play, of planting and harvesting, of
various human activities and festivities, it is the calendar measured in
seconds, minutes, hours, days, lifetime, generation, epoch. It is the reminder
that "we pass this way but once." And therefore, the greatest
gift of our existence. ~
