What Makes Water Freeze?
There are different states of matter.
A glass of water sitting on the table, the water is in liquid state. If you put the glass in the freezer what will happen? The water
in the glass will freeze. It will become a solid. It will change into one giant ice cube! If you take the glass out of the freezer
what happens? It will melt. If you leave it out for a long time, It will disappear. It doesn't really disappear. It changes from a
liquid to a gas. This is called evaporation.
Water and Weather!
The temperature outside affects the weather. If it is cold enough, it will snow. Snow is a solid. If it is warm enough then it will
rain. Rain is a liquid.
After it rains, the ground is wet. It won't stay wet forever. After the rain stops the water begins to evaporate. The water changes
from liquid to a gas. The gas drifts away in the air.
Why is there so much ice in Antarctica?
Why is there so much ice in Antarctica? Why doesn't it snow near the equator? Why don't penguins live in Florida? It all comes down
to the temperature! If the temperature stays below 32 degrees for a long time there will plenty of ice and snow to keep the polar
bears and penguins happy!
