"Powers" of the Equinox?
a Scientific Investigation
the equinoxes (approx. March 20 and September 22) the amount of day
and night are of equal length--approximately 12 hours each. There's
a "balance" of light and dark at almost all locations on earth.
some people believe that there is another kind of "balance"
on the equinoxes, a special kind of force that will make a raw
egg balance on its own end!
you think this is true? Is there some sort of cosmic "balance"
that makes eggs stand on their own on the equinoxes, but not
on other days? Is there a scientific way for you to test this?
This! Eggquinox on the Equinox?
When to Try This Experiment:
Scientific proof lies in repeated testing, to see if the results are
repeated or different with each test. It is important that you perform
this testing many times too, before, on, and after the equinox,
on the following schedule:
per week for the two weeks before the equinox;
once per week for the two weeks after the equinox.
(raw, in the shell)
smooth flat surface (and a steady hand)
your students will not break the eggs
beginning the experiment, have students record their initial hypothesis
in their journal. (Is there some special force that exists on
the equinox that allows eggs to balance on end?)
enough eggs so that there is one egg per student or group.
each egg, so each group uses the same egg in all tests.
a flat surface, have the students or groups try to balance their
egg on end. Students should record their results. This experiment
should be performed once a week for two weeks before the equinox,
then on the equinox, and then for two weeks after the equinox.
Be sure to refrigerate the eggs between experiments!
should record their findings in their journals after each experiment.
this experiment before, during and after the equinox. Then see what
the Scientist thinks.
eggs balance on the equinox?
about on other testing days?
your test results. Does there appear to be something different occurring
on the equinox?
do you interpret the data you have gathered?
variables can you think of which might impact whether an egg can
balance on its own?
