Make a Water Filter from a Bottle
How do towns clean the water that comes out of a faucet? One important step is filtering, which means passing water through layers that trap dirt. You can build a simple model of a water filter and watch muddy water come out much clearer.
Materials
an empty, clean plastic bottle (a large one works best)
scissors, used by an adult
a coffee filter or a few cotton balls
activated charcoal, sold for aquarium filters
clean sand
small gravel or pebbles
a cup of muddy water
a clear glass or jarSteps
1. Have an adult cut the bottle in half. Keep the top half to use as a funnel.
2. Rinse the charcoal, sand, and gravel in a strainer until the water runs clear, so their dust does not cloud your results.
3. Push the coffee filter or cotton balls into the neck of the bottle. Turn the top half upside down and set it in the glass or jar.
4. Add the layers in this order: about an inch of charcoal first, then about two inches of sand, then about two inches of gravel on top.
5. Slowly pour the muddy water over the gravel. Watch it trickle through the layers and drip into the glass.
6. Compare the filtered water with the muddy water you started with.
How It Works
Each layer traps something different. The gravel catches large bits, such as leaves and twigs. The sand catches smaller grains of dirt. The charcoal is full of tiny holes that hold on to some of the chemicals that give water a bad color or smell.Safety Note
Your filtered water may look clean, but it is not safe to drink. Germs and some chemicals are far too small for sand and charcoal to catch, and real water treatment plants use other steps to kill germs. Pour your filtered water on a plant instead.1.What should you do right before you pour the muddy water?
- AHave an adult cut the bottle in half.
- BPour the filtered water on a plant.
- CCompare the filtered water with the muddy water.
- DAdd the charcoal, sand, and gravel in layers.
- 2.
Where should a reader look to find out what the sand in the filter catches?
- AThe first paragraph
- BHow It Works
- CThe Safety Note
- DThe Materials list
The Radiator in 4B
Every winter morning, before the sun, the radiator under our window clears its iron throat. It knocks once, twice, three times, like an old man rapping his cane on the floor to tell the whole building he is awake. Then it hisses, long and low, grumbling about the cold the way Grandpa grumbles about the weather report, complaining and complaining but never once leaving its post. All day it works without a word of thanks. It dries the mittens we drape across its ribs. It lets the cat sleep along its warm shoulders. It wrestles the drafts that sneak under the door and pins them to the floor. Outside, the wind shakes the fire escape, and snow buries the parked cars to their mirrors. Inside, the radiator stands its ground. At night, when the building goes quiet, I hear it ticking as it cools, muttering to itself in the dark like someone humming a song whose words they have forgotten. Mom says it was already here before she was born, that it knocked and hissed and kept her warm while she did homework at this same table. People who visit call it noisy. I call it loyal. Not everything that grumbles is unkind. Some things complain all winter long and keep you warm anyway.
3.How does the speaker's view of the radiator differ from the view of visitors?
- AVisitors find it loyal, but the speaker finds it annoying.
- BVisitors enjoy hearing it at night, but the speaker cannot sleep.
- CVisitors think it makes the room too hot, but the speaker thinks it is too cold.
- DVisitors notice only its noise, but the speaker values how dependable it is.
- 4.
In the poem, what does the word "post" mean in "never once leaving its post"?
- Aa message shared online
- Ba seat beside a window
- Ca wooden pole set deep in the ground
- Dthe place where someone is on duty
Why Your Ears Pop
You are on a plane as it begins to descend for landing, or in a car winding up a mountain road, when suddenly your ears feel stuffed with cotton. Sounds go muffled. Then you swallow, and with a small pop, everything becomes clear again. What just happened inside your head?
The answer has to do with air pressure, because the air around us is constantly pressing on everything it touches, including your body. At sea level, that pressure is fairly high, because a tall column of air is pressing down from above. At higher elevations, there is less air above you, so the pressure decreases.
Inside each ear, just behind the eardrum, is a small, air-filled space called the middle ear. The eardrum is a thin sheet of skin stretched like the top of a drum. Normally, the air pressure in the middle ear matches the pressure outside, so the eardrum sits flat and vibrates freely when sound waves strike it.
When the outside pressure changes quickly, however, the pressure in the middle ear cannot keep up. On the way up a mountain, the outside pressure drops, and the air trapped in your middle ear pushes the eardrum outward. On the way down, the outside pressure rises and pushes the eardrum inward. Either way, a stretched eardrum can't vibrate well, so sounds seem dull, and your ears may even hurt.
The fix is a narrow passage called the Eustachian tube, which connects the middle ear to the back of the throat. It usually stays closed, but swallowing, yawning or chewing opens it briefly. Air rushes in or out until the pressure on both sides of the eardrum is equal again, and the eardrum snaps back into place. That snap is the pop you hear. It also explains why flying with a cold can be so uncomfortable: a cold can swell the Eustachian tubes shut, trapping the pressure inside.
5.According to the passage, what causes the pop a person hears?
- AThe Eustachian tube breaks open at high altitude.
- BThe eardrum snaps back into place once the pressure on both sides is equal.
- CSound waves strike the eardrum harder at sea level.
- DAir bursts out of the ear canal whenever a person yawns.
- 6.
In the passage, what does "muffled" mean in "Sounds go muffled"?
- Asofter and less clear
- Bfaster than usual
- Chigher in pitch
- Dlouder and much sharper
- 7.
Which sentence best states the main idea of the passage?
- APeople should never fly on an airplane when they have a cold.
- BThe eardrum is a thin sheet of skin stretched like the top of a drum.
- CEars pop when swallowing or yawning lets air even out the pressure on both sides of the eardrum.
- DAir pressure is higher at sea level than at the top of a mountain.
The Monkey and the Crocodile
A fable from the Panchatantra, a collection of animal stories from ancient India
A rose-apple tree grew on the bank of a wide river. Its fruit was the sweetest for miles, and in its branches lived a monkey.
One hot afternoon, a crocodile hauled himself out of the water to rest in the tree's shade. The monkey, who enjoyed company, tossed down a handful of fruit and called, "Try these, friend." The crocodile did, and he returned the next day, and the day after that. Soon the two were true friends, talking for hours while the river slid past. Each evening, the crocodile carried some of the fruit home to his wife.
His wife, however, had been thinking. "If the fruit is so sweet," she said, "imagine how sweet the heart of a monkey who eats it every day must be. Bring me his heart, or don't come home at all."
The crocodile was miserable, but he could not bring himself to refuse her. The next morning he said to the monkey, "My wife wants to thank you for all the fruit. Come to dinner. Climb on my back, and I'll carry you across."
The monkey had always wanted to see the far bank, so he jumped onto the crocodile's back, and they set off together. In the middle of the river, where the water was deepest, the crocodile's guilt got the better of him. "Forgive me," he blurted. "My wife wants to eat your heart."
The monkey's blood ran cold, but his voice stayed light. "Why didn't you tell me before we left? Monkeys never carry their hearts around with them; we keep them hanging safely in the treetops, and mine is back in the rose-apple tree. Take me there, and I'll fetch it."
The crocodile turned around at once, and the moment they reached the bank, the monkey sprang into the highest branches.
"Go home, my friend," he called down. "No creature keeps its heart in a tree, and no true friend carries another into deep water to betray him."
