While cleaning house today Cozette decided she wanted to see what would happen if she mixed up some water with some vegetable oil. She mixed it in some cold water and even after shaking it up all the oil pretty much went to the top.
Then she decided she wanted to see what would happen if she mixed some oil in with warm water; a lot of the oil mixed in.
Finally she got an clear plastic water bottle, filled it two thirds full with HOT water and added the oil. She shook it up just as the others. This time the oil mixed in with the water, turning it a yuck yellow.
She concluded that hot water and oil mix together pretty well, but not cold water.

Today we created a 30 page "homework" book for Cozette and the webkinz filled with Math problems, from simple addition to multiplications.
Cozette wanted to know why Ft. Lauderdale FL was so named:

SO... In Conclusion: 287 metres per second is about 642.000716 miles per hour
Cozette wanted to know why Ft. Lauderdale FL was so named:
Fort Lauderdale is a city (incorporated place) located in Broward County, FL on the east coast of Florida. The City got it's name from Major William Lauderdale who built the first fort at the rivers mouth in 1838 during the Seminole Indian wars. Fort Lauderdale was incorporated in 1911 with only 175 residents.
Population: 152,397 (US Census 2000).

Cozette Asked: "How Fast does sound travel":
To break the sound barrier you have to travel than the speed of sound.
The speed of sound in air actually varies with temperature. When representing air as an ideal gas the speed of sound can be represented as
c = square root(γRT)
where
γ = specific heat ratio = 1.4
R = specific gas constant = 287
T = Temperature in Kelvin.
Using this equation the speed of sound in dry air at:
-100 degrees Celsius is 264 metres per second
0 degrees Celsius is 343 metres per second
100 degrees Celsius is 287 metres per second.

Introduction
We are the "Elinas" This Blog is for Elina Cozette and Elina Rebecca to Journal the things we study and teach in "Webkinz School".
"Webkinz School" is where we teach our little furry friends about the world around them. Our class sizes vary, and traditionally "Miss Bird" (Rebecca's Bluefadoodle) is the "Teacher". But occasionally we have a substitute teacher. "Stripes" the Tiger is a fairly regular sub in our class room, but others may be noted from time to time.
Although Rebecca (aka. Momma) generally plays the roll of "Teacher" Cozette often takes her turn in this capacity as well.
Hope you all enjoy following us in "Webkinz School"!!!
