Have you ever rubbed your hands together when they get cold? Why do we do that? We do that for friction. Friction happens when two things that aren’t very smooth rub together to make heat energy. The faster you rub two things together, the more friction ( and heat) you can make. Let’s discover friction!
WHAT YOU’LL NEED:·Soap ·Water· Your hands!
WHAT TO DO:
1. Make sure your hands are dirty.
2. Rub your hands together until you feel the heat of your hands.
3. Now, use soap and water to get your hands very slippery(滑的).
4. Try to make friction happen while your hands are slippery.
5. Please write down what has happened.
LET’S TALK!
Friction is an energy that happens when two things rub together. When friction happens, it makes heat! When your hands are slippery, they won’t make very much friction and your hands won’t get so hot.

(2)Ancient people made fires by rubbing two pieces of wood together. Friction happened though they didn’t know it.
________?_________

American and British people both speak English of course. But sometimes it does not seem like the same language. In fact, there are some important differences between British English and American English.
1.Often, Americans don’t say each word separately. They say several words together. Americans may say “I dunno” instead of “I don’t know”. Or they may say “Whaddya say?” instead of “What did you say?” However, the British are more careful in their speech. They usually say all the words and keep them separate.
Sound is not only the difference between British English and American English. Words sometimes have different meanings too.2.Americans drive trucks, but in England people drive lorries.
3.In England, if you are going to telephone your friends, you “phone them up”. In America, you “give them a call”.
There are also some differences in grammar. For example, Americans usually use the helping verb “do” when they ask a question. They say “Do you have a storybook?” But the British often leave out the helping verb.4.
Most languages are like this. Languages change over time. When people live in separate places, the languages change in different ways. This is what has happened to English. It can also happen to other languages, such as French. Many people in Canada speak French but their French is very different from the French of France.

B.It can also happen to other languages, such as French.
C.For example, the vocabulary for cars and driving is very different.
