Introduction:
| About 20% of the earth dry
land is permanently covered by snow. In the winter about 40% of the northern
hemisphere lands are covered by snow. That is why thousands of
scientists and engineers around the world research different aspects
of snow. Some focus on snow control on roads, snow engineering and
avalanches. Some others research materials and equipment that
facilitates our lives on snow. Meteorologists work on characterization
and climate aspects of snow while geologists are more interested on glacial
and their effects on the earth surface.

The four projects listed above are not the
only projects that students can do related to snow. Everything from
chemical properties, physical properties, shapes of snow flakes, causes
and the effects of snow can be subjects of different science projects.
