You can go skating on ice, and that can be fun.
![Page 3: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/3.jpg)

But what is ice? Ice is very, very cold water!
![Page 5: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/5.jpg)
Water is made up of tiny, tiny, tiny little water molecules. Water molecules are called H20, which looks like this.
![Page 7: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/7.jpg)
Water can be liquid—we call this liquid water.
![Page 8: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/8.jpg)
![Page 9: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/9.jpg)
If water gets very hot, like when somebody puts a pot of water on the stove, it boils,
![Page 10: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/10.jpg)
![Page 11: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/11.jpg)
and if it gets even hotter than that, it makes steam.
![Page 12: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/12.jpg)
![Page 13: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/13.jpg)
But what happens when water gets cold? Water freezes
solid, like a rock—which we call ice, or water ice.
![Page 14: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/14.jpg)
![Page 15: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/15.jpg)
Water turns to steam when it is 212 degrees—that is hot!
![Page 16: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/16.jpg)
![Page 17: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/17.jpg)
But water freezes, and turns to ice at 32 degrees—that’s
cold enough for hat and mittens.
![Page 18: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/18.jpg)
![Page 19: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/19.jpg)
Take some water,
![Page 20: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/20.jpg)
![Page 21: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/21.jpg)
put it into an ice cube tray,
![Page 22: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/22.jpg)
![Page 23: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/23.jpg)
wait for the water to freeze, and out come ice cubes!
![Page 24: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/24.jpg)
![Page 25: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/25.jpg)
We use ice cubes to keep a drink cold.
![Page 26: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/26.jpg)
![Page 27: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/27.jpg)
If the air is warm, like it is in the house, an ice cube will melt. That means the ice
turns back into water!
![Page 28: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/28.jpg)
![Page 29: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/29.jpg)
If you put many ice cubes in warm air, they will melt, and
become liquid again.
![Page 30: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/30.jpg)
![Page 31: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/31.jpg)
Other things can melt, and become liquid; butter can
melt.
![Page 32: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/32.jpg)
![Page 33: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/33.jpg)
When the weather gets warm, snow and ice melts. First, it
becomes slush,
![Page 34: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/34.jpg)
![Page 35: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/35.jpg)
and then it becomes water.
![Page 36: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/36.jpg)
![Page 37: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/37.jpg)
Ice can be very pretty, like when icicles hang from a
house,
![Page 38: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/38.jpg)
![Page 39: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/39.jpg)
![Page 40: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/40.jpg)
or when ice covers tree branches.
![Page 41: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/41.jpg)
![Page 42: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/42.jpg)
Sometimes, rain freezes when it is falling. This is called
freezing rain.
![Page 43: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/43.jpg)

This coats everything with ice, which can be pretty,
![Page 45: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/45.jpg)
![Page 46: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/46.jpg)
![Page 47: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/47.jpg)
but it can also cover power lines.
![Page 48: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/48.jpg)

and that can make the power go out!
![Page 50: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/50.jpg)

In the winter, when it gets very cold,
![Page 52: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/52.jpg)

creeks can freeze over,
![Page 54: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/54.jpg)

and rivers can freeze over,
![Page 56: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/56.jpg)

and lakes can freeze over—so people can even drive on
them, sometimes!
![Page 58: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/58.jpg)

Roads can get icy in winter,
![Page 60: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/60.jpg)

and that can cause accidents!
![Page 62: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/62.jpg)

You can slip and fall when you walk on ice!
![Page 64: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/64.jpg)

So be careful!
![Page 66: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/66.jpg)

Glaciers are made of ice.
![Page 68: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/68.jpg)

Glaciers flow down valleys like rivers of ice.
![Page 70: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/70.jpg)

There is ice at the North Pole, filling up the Arctic Ocean,
![Page 72: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/72.jpg)

and ice covers Antarctica and Greenland, too.
![Page 74: Ice. You can go skating on ice, and that can be fun](https://reader036.vdocument.in/reader036/viewer/2022062806/56649f1e5503460f94c368e7/html5/thumbnails/74.jpg)

The End
