Properties of Water
What are some characteristics that make you different
from everybody else? Maybe you can play basketball
really well, or have a freckle on the tip of your elbow, or
maybe you can draw better than anybody else you know.
It may seem strange, but each substance in the world has
special characteristics that make it different from every
other substance. Just like you, they have characteristics,
or properties, that make them unique. Believe it or not,
water has some of the most unique properties of all!
