Abstract
Enchanting is the sight of the Milky Way on a
moonless night. Mesmerising are the photographs
of the distant universe, brought home to us via
the Internet by powerful telescopes like Hubble,
Spitzer and Chandra. The sky is accessible to
everyone and is a ‘universal laboratory’. However,
school hours are nearly always during day-time.
Combine this reality with the scourge of light
pollution, and practical star gazing within regular
school curricula is virtually ruled out - with one
exception. Our nearest star, the Sun, can play
‘laboratory’ during school hours! Thus, learning
science by doing and discovering can indeed
happen with day-time astronomy experiments. The Sun should not be stared at directly - it could
harm our eyes. The projection of the Sun’s image
described in the activities below is one of the safe
methods of viewing the Sun.
