Science experiments are a fun way for kids to learn all about science.I will introduce a few great experiments and teach your child all about the wonders of inertia(惯性).
Coin Shoot
You'll need some coins, at least eleven, and a smooth table.Stack(堆叠) all but one of the coins on the smooth table, making sure that the “high rise” is straight. Coins with wide edges make this experiment easy to do. Flick ( 弹 ) the extra coin quickly towards the bottom of the stack so that it hits the bottom coin.The bottom coin from the stack should shoot out from under the other coins without changing the rest of the stack. With good aim and quick flicks of your finger, you should be able to shoot all of the coins out of the stack one by one. Because the inertia of the stack of coins is so great, the force from the flicked coin is not enough to make the entire stack move or fall down.
The Pencil Standing
Place a narrow piece of paper on a smooth table. Hold the paper so that most of it hangs off the table.Place a pencil on the paper so that it is standing straight.Now,slowly try to pull the paper out from under the pencil.What happens? Set up the paper and pencil again, and give the paper a fast pull. What happens to the pencil this time?
Since the still pencil wants to stay at rest, it will be against the fast movement of the paper.This means that when the paper is moved quickly out from under the pencil, the pencil remains standing straight. If the paper is moved slowly, the movement has a chance to influence the pencil, and it will fall down.
1.Which of the following is used in both of the two experiments?
A.A narrow piece of paper. B.A number of coins.
C.A smooth table. D.A new pencil.
2.What result can we get if we do the first experiment well?
A.The stack of coins fall down on the table.
B.The bottom coin is flicked out of the stack.
C.All of the coins are taken away from the table.
D.All of the coins are shot out of the stack one by one.
3.Most of the paper hangs off the table so that .
A.we can pull it quickly B.we can take hold of it
C.it can influence the pencil D.the pencil can stand straight
4.If we pull the paper slowly out from under the pencil, the pencil will .
A.move slowly with the paper B.stand straight on the table
C.be shot out from the table D.fall down on the table

Pete Sparks was a sensitive (敏感的) boy. So sensitive that even his hair was ticklish (怕痒的). You only had to touch his hair a little bit and he would start laughing. When this ticklish laughter started, no one could make him stop.
Pete tried everything to control his ticklishness, but nothing worked. So he began to feel sad for being different.
One day in the street, he met a special clown. The clown was very old and could hardly walk, but when he saw Pete in tears, he went to cheer him up. It didn’t take long to make Pete laugh. Later Pete told him about his ticklish problem, and he asked the clown how such an old man could carry on being a clown.
“I have no one to take my place,” said the clown. “I have a very serious job to do.” Pete looked at him, surprised. “Come, I’ll show you,” said the clown. So the clown took Pete to many hospitals full of children who were sick. As soon as they saw the clown, their faces changed completely and lit up with a smile. Their short while spent with the clown changed everything for them. That day was even more special, because in every show Pete’s laughter would end up with the kids lying on the floor, dying with laughter. When the visit came to an end, the old clown said to Pete, “Now do you see why I can’t retire (退休), even at my age?”
That was how Pete became a clown, and took the special old man’s place. From that day on, the fact that Pete was different actually made him happy, thanks to his special gift (天赋).

In the last week, terrible floods have hit Prague, the beautiful old capital city of the Czech Republic. These are the worst floods for over 100 years, leaving thousands of people without homes.
The floods rushed into Prague zoo as well, and hundreds of zoo animals had to swim for their lives. One of the monkeys drowned in two minutes, because the place where he lived was covered by water.
An elephant, called Kadir, also drowned, but his death helped to save other animals. Kadir was famous because he had appeared on TV. When they heard the news of his death, hundreds of people phoned the zoo offering help.
After the sad news of the elephant’s death, many volunteers came to the zoo to help the animals. This was not easy. They had to use the huge machines to lift things onto ships. Without these, it would have been impossible to lift the very large animals like elephants.
Other animals swam out and were found in the rivers. One of the seals, Gaston, swam to Germany, 120 kilometers away. In the end, four hundred animals were salvaged.
