Students and families, I hope that each and every one of you has a happy holiday! We will continue our learning after the winter break. Also, congratulations on being done Mater and Chemical Change (at least until the Provincial Achievement Test in Spring)!
Sincerely,
Mr. Mang

For your interest, the day I'm posting this message is the shortest day of the year (December 21st) a day called the winter solstice. What does this mean scientifically? It means because of the earths tilt (23.5) degrees and where the earth is in its orbit around the sun, the suns' rays actually hit earth most directly at 23.5 degrees South Latitude on this day; that is why we have summer in the Southern Hemisphere right now and winter in the Northern Hemisphere. As the winter progresses, the day will actually lengthen (in terms of hours of light vs hours of dark) and the suns rays will gradually hit the norther hemisphere more directly. On March 21, the suns rays will hit the equator most directly and humans will experience 12 hours of light and 12 hours of darkness in almost every habitable place on our planet; that is why we call this day the equinox (more specifically the vernal equinox). The day keeps getting longer until the first official day of summer (June 21) when the suns rays hit 23.5 degrees North latitude most directly (the tropic of Cancer). If you read this paragraph and understood it... well done!
