Learn how to play chess in just 3 easy steps:
For ages 4 and up. 2 players minimum and maximum.


1.First of all I am going to tell you wich piece can go how many steps and
how they move. The ponds could move 1 step forward each turn but on
the first turn of each of the ponds can move 2 steps but ONLY if you want. The castles can move horizontaly or verticaly 8The horses could move like a letter "L" and the letter L c> steps maximum.
direction you want,but the L has to be 3 steps in the direction you want
and then go 1 step left or right . The bishops could go diagonaly and
8 steps maximum.The queen can move in any direction and how many
steps you want it to go. The king could move 1 step in any direction
2.Step two. Now I am going to tell you how the chess pieces can attack.
The ponds can attack diagonaly 1 step butcan not attack backwards. The
castles can attack vert. or hor..Its the same thing with the horses,bishops,
queen and king except in different ways.
3.This is the last step and now I am going to tell you how to place the chess pieces. you don't have to skip a space to place your chess pieces. You just
need two lines to place both player's chess pieces. In front you will have
all your ponds fit in the front row. Then you put your castles on the two
corners of the back row. Then you put your two horses beside (left for
right side and right for left side)your two castles then you put your two
bishops beside your two horses and finally your queen and king on any
side you want beside your two bishops.
Your goal is to kill your opponents' king before he kills yours.If you or your opponent
kills the king but that player still has other chess pieces remaining ,the other player still
wins.Whoever kills a players' king, wins.
This is a good strategie for chess :
1.You could put all your ponds in a zig zag so if your opponent's chess piece
kills one of your ponds you could kill him back.

Flagship Teams
The Kanata Soccer Club has recently approved the establishment and support of representative Flagship teams. This year both the representative Ladies and Men's sides of the club will focus on fielding such a team. These teams will be comprised of a select group of players having the talent, desire and potential to play at the premier levels in the OCSL.
The overall objectives of this undertaking are to provide a vehicle where the club can showcase the skills and performance of our developing players and ensure that Kanata will always be strongly and proudly represented at the premier levels of the game in the Ottawa / Carleton area. With this in mind the club is encouraging all Kanata resident players to seriously consider the Flagship teams in their future playing decisions and to take advantage of the special opportunities that this program will offer as it develops
apart: Circuit BoardThe following two photos show how the plastic bar applies power to the toaster. In the first photo, the plastic bar is being simulated by a pencil, and you can see how it pushes the contacts

In this particular toaster, here is how the whole mechanism works:
When you push down on the handle, the plastic bar presses against the contacts and applies power to the circuit board. 120-volt power runs directly through the contacts to the nichrome wires to start toasting the bread. A simple circuit made up of transistors, resistors and capacitors turns on and supplies power to the electromagnet. The electromagnet attracts the piece of metal on the handle, holding the bread in the toaster. The simple circuit acts as a timer. A capacitor charges through a resistor, and when it reaches a certain voltage it cuts off the power to the electromagnet. The spring immediately pulls the two slices of bread up. In the process, the plastic bar rises and cuts off power to the toaster. In this toaster, the darkness control is simply a variable resistor. Changing the resistance changes the rate at which the capacitor charges, and this controls how long the timer waits before releasing the electromagnet. Less sophisticated toasters use a bi-metallic strip (see How Thermometers Work for details on bi-metallic strips) to turn off the electromagnet. As the strip heats up (due to rising temperatures inside the toaster), the strip bends and eventually trips a switch that kills the power to the electromagnet. The bi-metallic strip approach has two problems:
If the kitchen is cold, the first piece of toast will be darker than usual. If you try to make a second batch of toast, it will be too light because the toaster is already hot. The electronic circuit in this toaster provides much more consistent toast!
If you actually need to get somewhere, a hot air balloon is a fairly impractical vehicle.You can't really steer it, and it only travels as fast as the wind blows. But if you simply want to enjoy the experience of flying, there's nothing quite like it. Many people describe flying in a hot air balloon as one of the most serene, enjoyable activities they've ever experienced.
Hot air balloons are also an ingenious application of basic scientific principles. In this article, we'll see what makes these balloons rise up in the air, and we'll also find out how the balloon's design lets the pilot control altitude and vertical speed. You'll be amazed by the beautiful simplicity of these early flying machines!
Hot air balloons are based on a very basic scientific principle: warmer air rises in cooler air. Essentially, hot air is lighter than cool air, because it has less mass per unit of volume. A cubic foot of air weighs roughly 28 grams (about an ounce). If you heat that air by 100 degrees F, it weighs about 7 grams less. Therefore, each cubic foot of air contained in a hot air balloon can lift about 7 grams. That's not much, and this is why hot air balloons are so huge -- to lift 1,000 pounds, you need about 65,000 cubic feet of hot air! To find out exactly how this works, skip to Air Pressure + Gravity = Buoyancy.
To keep the balloon rising, you need a way to reheat the air. Hot air balloons do this with a burner positioned under an open balloon envelope. As the air in the balloon cools, the pilot can reheat it by firing the burner.
Modern hot air balloons heat the air by burning propane, the same substance commonly used in outdoor cooking grills. The propane is stored in compressed liquid form, in lightweight cylinders positioned in the balloon basket. The intake hose runs down to the bottom of the cylinder, so it can draw the liquid out.
The burner flame heats the air in the balloon envelope.
Because the propane is highly compressed in the cylinders, it flows quickly through the hoses to the heating coil. The heating coil is simply a length of steel tubing arranged in a coil around the burner. When the balloonist starts up the burner, the propane flows out in liquid form and is ignited by a pilot light. As the flame burns, it heats up the metal in the surrounding tubing. When the tubing becomes hot, it heats the propane flowing through it. This changes the propane from a liquid to a gas, before it is ignited. This gas makes for a more powerful flame and more efficient fuel consumption.
In most modern hot air balloons, the envelope is constructed from long nylon gores, reinforced with sewn-in webbing. The gores, which extend from the base of the envelope to the crown, are made up of a number of smaller panels. Nylon works very well in balloons because it is lightweight, but it is also fairly sturdy and has a high melting temperature. The skirt, the nylon at the base of the envelope, is coated with special fire-resistant material, to keep the flame from igniting the balloon.
The hot air won't escape from the hole at the bottom of the envelope because buoyancy keeps it moving up. If the pilot continually fires the fuel jets, the balloon will continue to rise. There is an upper altitude limit, however, since eventually the air becomes so thin that the buoyant force is too weak to lift the balloon. The buoyant force is equal to the weight of air displaced by the balloon, so a larger balloon envelope will generally have a higher upper altitude limit than a smaller balloon
