Ice is what happens to water when it is so cold that it freezes. You can see ice as snow in winter. Snow is just tiny bits of ice. In summer, people make their drinks cooler by putting ice in them.
Icebergs are huge chunks of ice that break off from the ice collected around land, or from glaciers that reach the sea. They float, but most of them is underwater and you can't see it, which has coined the phrase "tip of the iceberg" meaning that you can only see a small part of something and the problem is actually a lot bigger than it seems.
Ice cream is a dessert made from frozen milk or cream. Icecream is usually flavoured with sugar, vanilla, fruit or chocolate. Icecream is made by freezing the milk or cream slowly and stirring it frequently so it stays smooth. If you don't stir it, it will be full of crunchy ice crystals and will not be as nice. Icecream is sometimes served in a cone.
An idea is something you think of inside your head. Often, an idea is something new that you haven't thought of before, and when an idea comes on suddenly it can solve a problem you have been thinking about.
Identification, or ID, is something you use to prove to other people that you are who you say you are. Most identification has a photograph of you on it. People generally carry some form of identification in their wallet.
An igloo is a house made from blocks of snow. They are made by people who live in very cold areas, such as Inuit Eskimos and the people in Canada's north and Greenland.
