A student is checking a partner’s writing for vague language. Which part of this sentence is the most vague and should be revised?
"During the experiment, we changed the stuff in the cup and it made the reaction happen faster."
"happen faster"
"During the experiment"
"the stuff in the cup"
"changed"
Explanation
When checking for vague language, we need to identify which phrase lacks precision and clarity. "The stuff in the cup" (Option C) is the most vague part because "stuff" doesn't tell us what substance or material was actually in the cup - it could be a liquid, solid, chemical solution, or anything else. The other parts of the sentence are relatively clear: "During the experiment" (A) sets the time, "changed" (B) indicates an action was taken, and "happen faster" (D) describes the effect on reaction rate. To improve this sentence, the student should replace "stuff" with the specific name of the substance, such as "the sodium bicarbonate solution" or whatever material was actually used.
Topic: writing about weather (Earth science). A student wrote, “It got really bad, so school closed.” What makes this sentence vague and less informative?
It uses unclear words like “really bad” and does not name the weather event (for example, blizzard, tornado warning, or flooding).
It uses the correct domain vocabulary, but it is too long.
It includes too many specific numbers and dates.
It uses a technical term that is too advanced for 7th grade.
Explanation
The sentence 'It got really bad, so school closed' lacks precision in multiple ways. Choice C correctly identifies the main problem: the phrase 'really bad' is unclear and the sentence doesn't name the specific weather event. Without knowing whether it was a blizzard, tornado warning, or flooding, readers can't understand what actually happened or why school needed to close. The word 'it' is also vague - readers must guess what 'it' refers to. Choice A incorrectly suggests technical terms are the issue, Choice B wrongly focuses on numbers and dates, and Choice D mistakenly claims the problem is length. Precise writing requires naming specific weather events and avoiding vague descriptors like 'really bad' so readers can clearly understand the situation.
Topic: linear expressions (math). A student wrote, “The number in front of $x$ matters.” Which domain-specific term precisely names “the number in front of $x$” in an expression like $7x + 3$?
Integer
Equation
Variable
Coefficient
Explanation
In the expression 7x + 3, the student refers to 'the number in front of x' which needs a precise mathematical term. Choice A, 'Coefficient,' is the correct domain-specific term for the numerical factor that multiplies a variable. In this case, 7 is the coefficient of x. Choice B (Integer) just means a whole number, Choice C (Equation) refers to a mathematical statement with an equals sign, and Choice D (Variable) would refer to the x itself, not the number in front of it. Using 'coefficient' instead of 'the number in front of x' gives students the proper mathematical vocabulary they need to discuss algebraic expressions accurately and efficiently in their mathematical communication.
A student wrote this sentence about the water cycle: “Water goes up, makes clouds, and comes down.” Which revision is the most precise for a 7th-grade science explanation?
Water evaporates into water vapor, condenses into clouds, and precipitates as rain or snow.
Water goes up somehow, turns into cloud stuff, and drops back down.
Water travels around in the sky and then falls.
Water moves a lot, so the weather changes.
Explanation
Scientific explanations require precise vocabulary that accurately describes natural processes. The original sentence uses informal language like 'goes up' and 'comes down' without naming the specific processes. Option A still uses vague language with 'travels around.' Option C includes 'somehow' and 'cloud stuff,' showing uncertainty and imprecision. Option D is too general with 'moves a lot.' Option B is the best revision because it uses the correct scientific terms: 'evaporates' (for water becoming vapor), 'condenses' (for vapor becoming liquid droplets in clouds), and 'precipitates' (for water falling from clouds). These domain-specific terms precisely name each stage of the water cycle, making the explanation clear and scientifically accurate.
Topic: photosynthesis (life science). In a lab report, a student wrote, “Plants make food using light.” Which revision is most precise and uses correct scientific vocabulary?
Plants make their meals when light hits them.
Plants create energy by being in the sun a lot.
Plants do a process that turns sunlight into food stuff.
Plants synthesize glucose through photosynthesis, converting light energy into chemical energy stored in sugar molecules.
Explanation
The student's original sentence 'Plants make food using light' is too simple and doesn't explain the scientific process. Choice C provides the most precise revision by using the correct scientific terms: 'synthesize glucose,' 'photosynthesis,' and 'converting light energy into chemical energy.' These domain-specific words accurately describe what happens - plants don't just 'make food,' they create glucose molecules through a specific process. The revision also explains that energy changes form, from light to chemical energy stored in sugar. While choices A, B, and D try to explain the concept, they use informal language like 'meals,' 'food stuff,' or 'being in the sun' that doesn't convey the scientific precision needed for a lab report. Scientific vocabulary helps readers understand exactly what process is occurring.
Topic: U.S. government (social studies). A student wrote, “A law changed voting.” Which revision is most precise and helps readers understand exactly what happened?
A big rule made voting fairer for people.
A new law made it so people could vote more easily.
The government did something that helped voting.
The Voting Rights Act of 1965 prohibited racial discrimination in voting practices, expanding access to suffrage.
Explanation
The original sentence 'A law changed voting' is extremely vague - it doesn't tell us which law, when it happened, or how voting changed. Choice B is the best revision because it provides specific information: the exact name of the law (Voting Rights Act), the year (1965), and what it did (prohibited racial discrimination in voting practices). The phrase 'expanding access to suffrage' uses the precise term 'suffrage' (the right to vote) to explain the law's impact. Choices A, C, and D remain too general with phrases like 'big rule,' 'something that helped,' or 'new law' that don't give readers the specific historical information they need. In social studies writing, naming specific laws, dates, and using terms like 'suffrage' helps readers understand exactly what historical event is being discussed.
A student wrote this about the water cycle: "Water goes up and comes down." Which revision is the most precise and uses correct science vocabulary?
Water rises, cools, and then comes down as water.
Water goes into the sky, makes clouds, and then falls.
Water travels up because of heat and returns when it gets heavy.
Water evaporates from lakes and oceans, condenses into clouds, and later precipitates as rain or snow.
Explanation
The original sentence "Water goes up and comes down" is extremely vague and doesn't explain the water cycle properly. Option C is the best revision because it uses precise scientific vocabulary: "evaporates" (instead of "goes up"), "condenses" (explaining cloud formation), and "precipitates" (instead of "comes down"). These domain-specific terms accurately describe each stage of the water cycle. Options A, B, and D still use imprecise language like "goes into the sky," "rises," or "travels up," which don't scientifically explain the process. Using proper scientific vocabulary helps readers understand exactly what happens during each phase of the water cycle.
In a social studies paragraph, a student wrote: "A law changed things for voting." Which sentence is the most precise revision?
An important law changed voting and improved equality for everyone.
The Voting Rights Act of 1965 prohibited racial discrimination in voting, protecting access to the ballot for many citizens.
A law was passed a long time ago that made voting more fair.
The government made rules that helped people vote.
Explanation
The vague sentence "A law changed things for voting" needs specific details and proper social studies vocabulary. Option C provides the most precise revision by naming the specific law ("The Voting Rights Act of 1965"), using the legal term "prohibited," and clearly stating what it did ("racial discrimination in voting"). This revision also uses "protecting access to the ballot," which is more precise than general phrases about fairness or helping people. Options A, B, and D remain vague with phrases like "a long time ago," "made rules," or "changed voting." In social studies writing, naming specific laws, dates, and using proper legal terminology creates clear, accurate explanations.
In a social studies paragraph, a student wrote: “A law changed voting.” Which revision is most precise and uses appropriate domain-specific vocabulary?
Some leaders changed the voting system a long time ago.
A law stopped unfair things and helped lots of voters.
The Voting Rights Act of 1965 prohibited racial discrimination in voting, expanding suffrage for many citizens.
A government rule made voting more fair for people.
Explanation
The original sentence "A law changed voting" lacks specificity and doesn't tell readers which law or how voting changed. Option B provides the most precise revision by naming the specific law ("The Voting Rights Act of 1965"), using the domain-specific term "suffrage" (the right to vote), and explaining what the law did ("prohibited racial discrimination"). This precision helps readers understand exactly what historical event is being discussed and its significance. Options A, C, and D remain vague with phrases like "a government rule," "unfair things," or "some leaders," which don't provide the specific information needed in social studies writing. Using precise names and terms helps students write clear, informative paragraphs about history.
A student wrote this in a history summary: "People were treated unfairly, so the government did something." Which revision is most precise and uses appropriate social studies vocabulary?
People had problems, so leaders helped them.
Some people were sad, so the government fixed it.
Because of discrimination, the federal government passed legislation to protect civil rights and reduce unequal treatment under the law.
The government made changes because things were not equal.
Explanation
The vague sentence "People were treated unfairly, so the government did something" needs specific historical vocabulary and details. Option D provides the most precise revision using proper social studies terms: "discrimination" (instead of "treated unfairly"), "federal government" (specifying which level), "passed legislation" (instead of "did something"), and "civil rights." It also explains the purpose clearly with "protect civil rights and reduce unequal treatment under the law." Options A, B, and C remain vague with phrases like "had problems," "were sad," or just "made changes." Historical writing requires specific vocabulary that accurately describes governmental actions and social issues.
