A Fond Farewell From And To Mrs. Berger's Class Thank you Mrs. Berger's 5th Grade Class at East Hills School in NY! "As the sun slowly sinks into the west, Mrs. Berger's class bids a fond adieu. Our large graph of the photoperiods for these sites came out stupendously. Learning how to subtract time measures was a challenge, what with borrowing 60 minutes from the hours column, but we did it! And what a charge to see all the lines meet at the equinox. Good luck to all of you on guessing where every site is!" Hurray--three cheers to Mrs. Berger and her students for the terrific job of gathering the sunrise/sunset times each week! This is very hard work, and they did a great job all season long. We really appreciate all of your hard work and assistance. Thanks again! If you'd like to drop a note of thanks to Mrs. Berger's class, you can reach them at: K12robzj@hofstra.edu or jberger@dorsai.org Special Thanks And Black Holes We'd also like to thank one of the "behind the scenes" contributors, Rod Nerdahl, Program Coordinator at the Minneapolis Planetarium. Rod helped keep our weekly sunrise and sunset listings "on time" by researching and providing standard sunrise/sunset and latitude/longitude data. Many thanks, Rod! Check out the Planetarium's website below which is full of "Black Holes and Dinosaurs In The Dark Of Night"!

Mystery Class #: # 1 In 1978 our city hosted several matches (i.e. kick-off and final) of our favorite sport's world championships. # 2 It's a town near the river "Danube". # 3 Our town was founded in 1902 by an English sea captain, Sir Robert Falcon Scott. # 4 Our city has the largest population in the province, but is not the capital city. # 5 Although the mountains in our country's interior get winter snow, our weather is overall very mild. This is due to the huge oceans surrounding us that take "all summer to heat up, & all winter to cool down ". Hence summer daytime temps. peak at about 30C ( 90F), with winters about 10C(50F). Almost no homes have a furnace or air conditioner ... they're not needed. However wood fireplaces are common. It can get windy here however, but overall we get LOTS of sun ( even in winter) to compensate... 1997 saw 2000 hours of bright sun in our nearby city, with some regions getting 2500 hours. # 6 Our school is on an American Air Force Base. # 7 We live in a city that has the longest bridge in Asia and the longest escalator in the world. # 8 Our capital starts with an "H" # 9 Our country was founded by Sir Stamford Raffles in 1819. # 10 A Game and Fisheries Research Institute is situated in our village. They are engaged in research work and do among other things some electric fishing here. The Next Mystery Class Update Will be Posted: May 1, 1998 Copyright 1998 Journey North. All Rights Reserved.
