Oh, my, my. It’s December, which means it’s holiday season already. I can tell because the Surfnetkids Christmas games are making it onto our Daily Top Ten list.
Here’s a list of all our winter holiday games (including Hanukkah, Christmas and Kwanzaa.)
See ya on the Net,

#2. An Easy Way to Use the Internet in the Classroom
If you know the right sites, the Internet can be a powerful
blessing that sparks a passion for self-directed learning.
But which sites do you recommend? How do you find them?
Let me help you.

Buoyancy Printable (** for premium members only)
Buoyancy is the upward force that keeps things afloat. When placed in water, an object will float if its buoyancy is greater than its weight. And it will sink if its weight is greater than its buoyancy. Learn more about the physics of buoyancy and density at the following sites.
Archimedes of Syracuse: The Father of Buoyancy
“People have been aware of objects floating on water (or sinking) since before recorded history. But it was not until Archimedes of Syracuse came along, that the theory of flotation and the buoyancy principle were defined.” Archimedes was a mathematician born in 287 BCE, in the city of Syracuse on the island of Sicily According to this University of Utah site, Archimedes is best remembered for a discovery involving the crown of King Hiero II. Learn why Archimedes shouted “Eureka!” and how he proved that the king’s crown maker had defrauded him.
For high-school and college physics students, HyperPhysics is an illustrated, hyperlinked, mind map of hundreds of physics topics. The material can be scrolled through from top to bottom or you can jump around, following the links in each short article. Topics related to buoyancy include density, mass, weight, fluid pressure, submerged volume, buoyant force, Archimedes Principle, and Pascal’s Principle.
NASA: Buoyancy: Archimedes Principle
Helicopters and airplanes depend on thrust and forward speed to fly. Hot air balloons and dirigibles rely on buoyancy (or differences in air density) for lift. This NASA page for high school students is part of a larger site on aeronautics. It offers a short article on buoyancy, and concludes with five exercises to test your understanding of the Archimedes Principle. At the bottom of the page you’ll find links to more aeronautics topics.
#4. Note from a Subscriber
Thanks for the ‘Cold War’ topic this week, it couldn’t be more timely as my year 7 son has to complete a biography on JFK, and has chosen the Cuban missile crisis as his speech topic. For an Australian, this means quite a search and you’ve helped narrow it down greatly. Love the weekly newsletter, and the fact I can talk to you way over there from way over here.
Thanks for the note and story. Every week I get email from readers about how my choice of topic was uncanny and timely. Except last week, when several readers noted that my Thanksgiving topic was sent AFTER school was already out for the long holiday weekend. Sorry about that! I must confess that Thanksgiving snuck up on me this year, so my holiday column was a teeny bit later than it should have been.
