Keesh lived at the North Pole a long time ago. He was a bright thirteen-year-old boy with a strong, healthy body. His father was a brave man who had died during a food shortage. His father tried to save the lives of his people by fighting a giant polar bear. The meat from the bear kept the people from hunger.

Keesh was his only son, and he lived alone with his mother. But people soon forgot how Keesh¡¯s father had saved their lives. They were forced to live in the poorest house in the village.

One night there was a meeting in the chief¡¯s large house. At that meeting, Keesh showed how much courage he had. He rose to his feet and went on steadily, ¡°Because my father, Bok, brought home more meat than any other hunter, everyone received a fair share, but now my mother and I were given meat filled with bones.¡± The hunters were shocked to hear a child speak to them that way.

Keesh waited calmly until the shouting died down. ¡°My mother has no one except me, and therefore I must speak. My father put his life in danger and died, to offer food to this village. It is only right that I, his son and his wife should have enough good meat as long as there is plenty of good meat in this village. I, Keesh, the son of Bok, have spoken.¡± He sat down. They threatened to punish him by not giving him any food at all. Keesh¡¯s eyes flashed(ÉÁ˸) and the blood pounded(³å»÷) under his skin, he jumped to his feet.

¡°Listen to me, you men!¡± he shouted. ¡°I shall never speak in this meeting again¡ªnot until you come to invite me to speak. My father was a great hunter, and so will I be.¡±

They laughed and shouted at Keesh. But Keesh said nothing more. He walked away with his head raised, looking neither to the left nor the right¡­¡­

Where does your food come from? How is it made? These days, many people worry about food safety. But food safety is not a new worry. In 1906, Upton Sinclair wrote the Jungle. The book is the story of a poor family in Chicago. It is also about the dangerous ways that food was prepared. People were so worried that the U£®S. started testing food.

These days, most food in the world is safe. Laws control where food comes from. They also control how food is managed and prepared. Laws are important. But__it's__more__important__to__make__sure__the__rules__are__followed. A good food safety system (ϵͳ) keeps people safe. It also helps them eat healthy food. Labels (±êÇ©) on food give people important information. Then they can make good choices about their food.

Although food safety systems usually work, there can be problems. Sometimes mistakes are made. For example, a truck might carry eggs and then ice cream. The ice cream could make people sick when the truck isn't cleaned before carrying it. Other problems are not mistakes. Sometimes companies break rules to make more money. When this happens, people don't know if their food is safe.

As we all know, food is closely related to our daily life. We should take action to make food safer!

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£º

¡ñA piece of soap ¡ñWater ¡ñYour hands

WHAT TO DO£º

1.Make sure your hands are dry.

2.Rub your hands together until you feel the heat of your hands.

3.Now£¬use a piece of soap and water to get your hands very slippery (»¬µÄ)£®

4.Try to make friction happen while your hands are slippery.

5.Please write down what has happened.

LET'S TALK!

Friction is a kind of energy that happens when two things rub together. When friction happens, it makes heat! When your hands are slippery, they won't make much friction and your hands won't get so hot.

DID YOU KNOW?

1.Friction happens when you stop your fast running bike.

2.Ancient people made fires by rubbing two pieces of wood together. Friction happened though they didn't know it.

__________

Friction is everywhere. Have you ever noticed situations where friction is happening? If not, ask your parents to take you out in a car. If it is not too hot, touch the tires (ÂÖÌ¥) of the car before and after a short drive to see how much warmer they get from friction.
