Two versions of Town Mouse/Country Mouse

Today you will read two stories: “The Town Mouse and the Country Mouse” by Aesop and an abridged version of “The Tale of Johnny Town-Mouse” by Beatrix Potter. You will then answer several questions based on the texts. Read each passage and questions. Then follow the directions to answer each question.

“The Town Mouse and the Country Mouse” by Aesop

Now you must know that a Town Mouse once upon a time went on a visit to his cousin in the country. He was rough and ready, this cousin, but he loved his town friend and made him heartily welcome. Beans and bacon, cheese and bread, were all he had to offer, but he offered them freely. The Town Mouse rather turned up his long nose at this country fare, and said: “I cannot understand, Cousin, how you can put up with such poor food as this, but of course you cannot expect anything better in the country. Come home with me and I’ll show you how to live. When you have been in town a week you will wonder how you could ever have stood a country life.” No sooner said than done: the two mice setoff for the town and arrived at the Town Mouse’s residence late at night. “You will want some refreshment after our long journey,” said the polite Town Mouse, and took his friend into the grand dining room. There they found the remains of a fine feast, and soon the two mice were eating up jellies and cakes and all that was nice. Suddenly they heard growling and barking. “What is that?” asked the Country Mouse. “It is only the dogs of the house,” answered the other. “Only!” said the Country Mouse. “I do not like that music at my dinner.” Just at that moment the door flew open, and in came two huge dogs, and the two mice had to scamper down and run off. “Good-bye, Cousin,” said the Country Mouse. “What! Going so soon?” asked the other. “Yes,” he replied. “Better beans and bacon in peace than cakes and ale in fear.”

“The Tale of Johnny Town-Mouse” by Beatrix Potter

1 Johnny Town-mouse was born in a cupboard. Timmy Willie was born in a garden. Timmy Willie was a little country mouse who went to town by mistake, in a hamper. The gardener sent vegetables to town once a week by carrier; he packed them in a big hamper.

2 The gardener left the hamper by the garden gate, so that the carrier could pick it up when he passed. Timmy Willie crept in through a hole in the wicker-work, and after eating some peas-- Timmy Willie fell fast asleep.

3 He awoke in a fright, while the hamper was being lifted into the carrier's cart. Then there was a jolting, and a clattering of horse's feet; other packages were thrown in; for miles and miles--jolt- -jolt--jolt! and Timmy Willie trembled amongst the jumbled up vegetables. At last the cart stopped at a house, where the hamper was taken out, carried in, and set down.

4 Timmy Willie, who had lived all his life in a garden, was almost frightened to death. Presently the cook opened the hamper and began to unpack the vegetables. Out sprang the terrified Timmy Willie.

5 Up jumped the cook on a chair, exclaiming "A mouse! A mouse! Call the cat! Fetch me the poker, Sarah!" Timmy Willie did not wait for Sarah with the poker; he rushed along the skirting board till he came to a little hole, and in he popped.

6 He dropped half a foot, and crashed into the middle of a mouse dinner party, breaking three glasses. "Who in the world is this?" inquired Johnny Town-mouse. But after the first exclamation of surprise he instantly recovered his manners.

7 With the utmost politeness he introduced Timmy Willie to nine other mice, all with long tails and white neckties. Timmy Willie's own tail was insignificant. Johnny Town-mouse and his friends noticed it; but they were too well bred to make personal remarks; only one of them asked Timmy Willie if he had ever been in a trap?

8 The dinner was eight courses; not much of anything, but truly elegant. All the dishes were unknown to Timmy Willie, who would have been a little afraid of tasting them; only he was very hungry, and very anxious to behave with company manners.

9 "Why don't those youngsters come back with the dessert?" It should be explained that two young mice, who were waiting on the others, went skirmishing upstairs to the kitchen between courses. Several times they had come tumbling in, squeaking and laughing; Timmy Willie learned with horror that they were being chased by the cat. His appetite failed, he felt faint.

10 "Try some jelly?" said Johnny Town-mouse. "No? Would you rather go to bed? I will show you a most comfortable sofa pillow."

11 The sofa pillow had a hole in it. Johnny Town-mouse quite honestly recommended it as the best bed, kept exclusively for visitors. But the sofa smelt of cat. Timmy Willie preferred to spend a miserable night under the fender.

12 It was just the same the next day. Timmy Willie longed to be at home in his peaceful nest in a sunny bank. The food disagreed with him, and the noise prevented him from sleeping. In a few days he grew so thin that Johnny Town-mouse noticed it and questioned him. He listened to Timmy Willie's story and inquired about the garden. "It sounds rather a dull place. What do you do when it rains?"

13 "When it rains, I sit in my little sandy burrow and shell corn and seeds from my autumn store. And when the sun comes out again, you should see my garden and the flowers--roses and pinks and pansies--no noise except the birds and bees and the lambs in the meadows."

14 "There goes that cat again!" exclaimed Johnny Town-mouse. When they had taken refuge in the coal-cellar he resumed the conversation. "I confess I am a little disappointed; we have endeavored to entertain you, Timothy William."

15 "Oh yes, yes, you have been most kind; but I do feel so ill," said Timmy Willie.

16 "It may be that your teeth and digestion are unaccustomed to our food; perhaps it might be wiser for you to return in the hamper."

17 "Oh? Oh!" cried Timmy Willie.

18 "Why of course! We could have sent you back last week," said Johnny rather huffily. "Did you not know that the hamper goes back empty on Saturdays?"

19 So Timmy Willie said good-bye to his new friends and hid in the hamper with a crumb of cake and a withered cabbage leaf; and after much jolting, he was set down safely in his own garden.

20 Sometimes on Saturdays he went to look at the hamper lying by the gate, but he knew better than to get in again. And nobody got out, though Johnny Town-mouse had half promised a visit.

21 The winter passed; the sun came out again; Timmy Willie sat by his burrow warming his little fur coat and sniffing the smell of violets and spring grass. He had nearly forgotten his visit to town. When up the sandy path all spick and span with a brown leather bag came Johnny Town-mouse!

22 Timmy Willie received him with open arms. "You have come at the best of all the year. We will have herb pudding and sit in the sun."

23 "H'm'm! It is a little damp," said Johnny Town-mouse, who was carrying his tail under his arm, out of the mud. "What is that fearful noise?" he started violently.

24 "That?" said Timmy Willie, "that is only a cow; they are quite harmless, unless they happen to lie down upon you. How are all our friends?"

25 Johnny explained why he was paying his visit so early in the season; the family had gone to the sea-side for Easter. The cook was doing spring cleaning, with particular instructions to clear out the mice. There were four kittens, and the cat had killed the canary.

26 "They say we did it; but I know better," said Johnny Town-mouse. "Whatever is that fearful racket?"

27 "That is only the lawn-mower; I will fetch some of the grass clippings presently to make your bed. I am sure you will never want to live in town again," said Timmy Willie.

28 But he did. He went back in the very next hamper of vegetables; he said it was too quiet!

2)The Australian ecosystem has open spaces with hills covered with plants, such as

grass and trees. One animal in this ecosystem is the kangaroo, which is a herbivore. Kangaroos are large marsupials found only in Australia.

British settlers began colonizing Australia in the late 1700s. In 1859, 24 European rabbits were brought to Australia to make new British settlers feel more at home. The feral, or wild rabbits which grew strong and reproduced rapidly, competed with the kangaroos for food and damaged the ecosystem.

In 1950, with approximately 600 million rabbits in Australia, scientists decided to try to lower the number of rabbits by releasing a disease into their environment. The disease killed many of the rabbits, but the dead rabbits created additional problems for the environment. Although there were manydead rabbits, eventually decomposers cleaned them up.

3) During the summer, Karen and her parents went diamond mining at Crater of

Diamonds State Park in Arkansas. While mining, Karen noticed that her father was placing multiple dark rocks into his pail to carry back to the processing pavilion. She noticed that as he picked up each of the darker colored rocks, they left traces of black dust on his hands. Her father scraped the edges of the dark rock with a pocket knife very gently. Karen asked her father about this observation, and he reminded her that diamonds are just pressurized coal. Karen remembered that coal was made from carbon.

Later, Karen and her parents sifted their collection in hopes of finding a diamond. Although her main goal was to find a diamond, Karen wondered how many different substances were actually in her pan. As Karen finished sifting her pan and looked at the pile of materials she had collected from her mining, she was disappointed to find that there were no diamonds. However, she did find some rusted iron screws.

4) Sheba’s Cooler Company is known for developing coolers, insulated containers

that are designed to keep food and drinks cool. Sheba and her engineers design a new cooler because several of their old coolers do not maintain an internal temperature of 40º Fahrenheit when it’s hot outside. Their design challenge is to develop a cooler that is the same size and mass and will not exceed an internal temperature of 40º Fahrenheit for at least ten hours a day when outside temperatures are 85º degrees Fahrenheit.

The engineers design a cooler that has a tight seal and thick insulation. Next, they develop an experiment to test their new design. The engineers fill an old and new cooler with 5 kilograms of ice, place the coolers in a room that is 85º Fahrenheit, and measure the internal temperature every two hours. Each ice filled cooler has a mass of 15 kilograms.

At the conclusion of the experiment the engineers measured the mass of each cooler and made a chart of their observations.

a)

Part ABased on the data, which two observations are true?

The internal temperatures of both coolers increased over the 10 hour period. The amount of liquid water increased, which caused the cooler to increase in mass.

The internal temperatures of both coolers did not change over the 10 hour period. The ice chemically reacted with the liquid water, which caused the cooler to increase in mass.

The internal temperature of the newly designed cooler did not exceed an internal temperature of 40º Fahrenheit over ten hours while the old design did. The mass of both of the coolers remained the same.

The internal temperature of the newly designed cooler increased over the 10 hour period. The water inside both of the coolers changed forms.

The temperature of the new design maintained an internal temperature of 40º Fahrenheit over ten hours while the old design did not. The ice melted faster in the new cooler.

Part BWhich evidence best supports the claim that matter was conserved in this

investigation?

a. The matter in the cooler changed over time and the total mass of the substances were the same.

b. The matter in the cooler changed over time and the matter was transported into and out of the system.

c. The temperature in the cooler changed over time and the total mass of the substances were not the same.

d. The temperature remained the same over time and the total mass of the substance were the same.
