The Night Before Regionals
CHARACTERS: JADA and MATEO, seventh graders and co-captains of the Westfield Middle School robotics team
(The robotics lab, late afternoon, the day before the regional competition. A robot sits on the workbench, its lifting arm hanging loose. MATEO is alone. He spots a cracked plastic gear on the floor, picks it up, studies it, and slides it into his pocket just as JADA rushes in with a sketchbook.)
JADA: I was up half the night drawing, and I've figured it out. We rebuild the whole arm, longer this time, so it can reach the top shelf and score double.
MATEO: Jada, the competition is tomorrow morning, and we've never once tested a longer arm.
JADA: Then we test it tonight. Every other team will play it safe, which is exactly why we shouldn't.
MATEO: Or we fix the arm we have, since it worked perfectly all season. Something small probably just slipped.
JADA: "Probably." (She flips the sketchbook open to a drawing.) It fell apart in the middle of your practice run, Mateo, in front of the whole team, so that's not small. Judges remember teams that take risks.
MATEO: Judges remember robots that move. If a new arm jams on the field, we score zero.
JADA: You always say that. You said it about the new wheels in October, and the wheels turned out to be the best thing we built all year.
MATEO: (His hand goes to his pocket and stays there.) This is different.
JADA: How?
(A long pause. MATEO looks at the robot, then at the floor.)
MATEO: It just is.
JADA: (closing the sketchbook) That's not a reason. Give me a real one in the next ten minutes, or I start taking the old arm apart.
(She crosses to the workbench and begins loosening bolts. MATEO pulls the gear out of his pocket, turns it over in his fingers, and opens his mouth to speak. Then he closes it and puts the gear away. The lights fade.)
1.How do Jada's and Mateo's points of view about the broken arm differ?
- ABoth want a longer arm, but they disagree about when to build it.
- BJada sees a chance to take a bold risk, while Mateo wants to repair the design they trust.
- CJada wants to drop out of the competition, while Mateo wants to enter it.
- DJada wants to keep the old arm, while Mateo has drawn a new design.
- 2.
Why does Mateo most likely refuse to explain why "This is different"?
- AShowing the gear might mean admitting the arm broke during his own run.
- BHe has not looked at the robot since practice.
- CHe has forgotten why the arm stopped working.
- DHe thinks the judges are listening at the door.
Make a Red Cabbage Color Indicator
Is lemon juice an acid or a base? What about baking soda? Chemists answer questions like these using the pH scale, which runs from 0 to 14: a substance with a pH below 7 is acidic, a substance with a pH above 7 is basic, and pure water, at 7, is neutral. A red cabbage indicator lets you test kitchen liquids yourself.
Materials
half a head of red cabbage
a knife and a cutting board
a pot, a strainer, and a large bowl
4 cups of water
4 clear plastic cups and a sheet of white paper
white vinegar, lemon juice, and baking soda
safety gogglesSteps
1. With an adult's help, chop the cabbage into small pieces and place them in the pot with the water.
2. Have an adult boil the water, then simmer it for about ten minutes, until it turns deep purple.
3. After the liquid has cooled completely, pour it through the strainer into the bowl and discard the cooked cabbage.
4. Pour about half an inch of the purple liquid into each cup, and set the cups on the white paper.
5. Leave the first cup as it is. Add a spoonful of vinegar to the second cup, a spoonful of lemon juice to the third, and a spoonful of baking soda dissolved in a little water to the fourth.
6. Stir each cup, and record the color you observe.
What Happened? Red cabbage contains natural pigments called anthocyanins, whose molecules change shape slightly depending on how acidic or basic their surroundings are. Because each shape absorbs light differently, each one displays a different color. In acids such as vinegar and lemon juice, the indicator turns pink or red, while in a base such as baking soda solution, it turns blue or green. The untouched purple cup shows the color of a nearly neutral liquid.
Safety Note: Wear goggles, and never taste or drink your samples. Never test bleach, drain cleaner, or other strong cleaners.
3.What should you do right before you pour the purple liquid into the clear cups?
- AStir each cup and record the color that you observe.
- BSet the four cups on the sheet of white paper.
- CAdd a spoonful of white vinegar to the second cup.
- DStrain out the cabbage once the liquid has cooled.
- 4.
Why does the procedure have you leave the first cup as it is?
- ATo show what happens when cabbage juice is heated
- BTo save extra indicator for a second test later
- CTo keep the experiment safe for younger children
- DTo give a color to compare the other cups against
- 5.
How does the section titled "What Happened?" help the reader?
- AIt explains the science behind the color changes.
- BIt gives the exact pH number of every liquid tested.
- CIt lists what to gather before starting.
- DIt warns which chemicals are unsafe to test.
Sunday Night, Monday Morning
Each Sunday night I call across the sea to where my grandmother's new day has begun. She asks the things she always asks of me: Am I eating? Am I warm? Is school still fun? I answer fast, one eye upon my screen, and half-hear stories I have heard before: the mango tree, the hen, the old machine that stitched her first school dress beside the door. Last week she asked me twice if I'd been fed, then laughed and blamed the hour and the line; and in that pause I heard what she had said beneath the words each Sunday, every time. So now I set my screen aside to tell her what I ate, then ask, "And are you well?"
6.Which statement best expresses the theme of the sonnet?
- AYoung people today care more about screens than about family.
- BLong-distance phone calls are a poor way for families to stay close.
- CSimple, repeated questions can carry a love that is easy to overlook.
- DGrandparents should try not to repeat the same old stories.
- 7.
How do the last two lines relate to the rest of the sonnet?
- AThey describe the speaker's hurry, which continues to the end of the poem.
- BThey introduce a new person who joins the phone call.
- CThey show how the speaker acts after the realization in the third stanza.
- DThey explain why the phone line was poor that week.
- 8.
How does the speaker's view of the grandmother's questions change during the poem?
- AThey seem like a chore at first, but later they sound like love.
- BThey seem like a pleasure at first, but later they grow tiresome.
- CThey seem confusing at first, but later they start to sound funny.
- DThey seem rude at first, but later the speaker asks her to stop.
Two Accounts of the Great Chicago Fire
Text 1: The Cow That Burned Chicago
On the night of October 8, 1871, Catherine O'Leary went out to the barn behind her small house on DeKoven Street to milk her cow. She set a kerosene lantern down in the straw. The cow, restless at the late hour, kicked over the lantern, and the dry straw burst into flames. Within minutes the barn was burning, and a strong wind carried sparks to the sheds and houses nearby, nearly all of them built of wood. For more than a day, the fire raced across Chicago. When it was finally over, about 300 people were dead and about 100,000 had lost their homes. All of it began with one cow and one careless kick.
Text 2: What Really Started the Fire?
Historians agree that the Great Chicago Fire began on the evening of October 8, 1871, in or near the barn behind the O'Leary home. What they cannot agree on is the cause, because no one has ever proved the story about the cow.
Weeks after the fire, city officials held an inquiry and questioned dozens of witnesses. Catherine O'Leary told them she had been in bed when the fire started. In the end, the officials could not say how it began.
The cow story first spread through the newspapers. In 1893, a reporter named Michael Ahern admitted that he and other reporters had made it up because it made a lively story. By then, many people had already blamed Mrs. O'Leary for the disaster, partly because she was a poor Irish immigrant, and the story followed her for the rest of her life.
In 1997, the Chicago City Council passed a resolution officially clearing Mrs. O'Leary and her cow.
9.How does Text 2 make Text 1 less reliable?
- AIt shows that the fire started in a different city.
- BIt reveals that a reporter admitted making up the cow story.
- CIt gives a much lower count of the people who died.
- DIt explains that the barn was built of brick.
- 10.
According to Text 2, what did Catherine O'Leary tell the officials who looked into the fire?
- AShe had been in bed when it started.
- BShe had watched it start from her window.
- CShe had left a lantern in the barn.
- DHer cow had kicked over a lantern.

Members of the school board, our district should install solar panels on the roofs of its schools. According to the US Department of Energy, the cost of installing solar panels has fallen sharply since 2010. Electricity from the sun would lower the district's energy bills and free up money for teachers, books, and equipment. Some board members argue that the panels would cost too much to install in the first place. However, the savings on monthly electric bills would gradually pay back the cost of the panels. Solar panels would be a smart, money-saving investment for our district, and I urge the board to approve them.
Who is the writer most likely writing this paragraph for?
- Athe members of the school board
- Bthe crew of a fishing boat
- Ca class of first graders
