Question 1
To avoid plagiarism in a biography report, which student sentence correctly uses paraphrasing with a citation?
Research question: What was one major achievement of Jane Goodall?
Source (PRINT): "Jane Goodall." Britannica School, 2021, pp. 2-3. Type: encyclopedia database printout. Excerpt: "Goodall's careful observations showed that chimpanzees make and use tools, which changed how scientists understood them." Credibility notes: edited database; date listed.
Choose the best student sentence.
- Goodall's careful observations showed that chimpanzees make and use tools, which changed how scientists understood them.
- Goodall proved chimps use tools and it changed science (Britannica School, 2021). (correct answer)
- Goodall's careful observations showed that chimpanzees create and use tools, which changed how scientists understood them.
- Chimpanzees make and use tools, and scientists changed their understanding because of Goodall.
Explanation: This question tests CCSS.W.6.8 (gathering relevant information from multiple print and digital sources, assessing source credibility, quoting or paraphrasing properly while avoiding plagiarism, and providing basic bibliographic information). When researching, students must use sources properly: PARAPHRASING = restating in own words with different structure AND citation. The source states "Goodall's careful observations showed that chimpanzees make and use tools, which changed how scientists understood them." Option B correctly paraphrases: "Goodall proved chimps use tools and it changed science" - significantly reworded and condensed while maintaining meaning, plus proper citation (Britannica School, 2021). The correct answer demonstrates proper paraphrasing with all required elements: different words ("proved" for "observations showed," "chimps" for "chimpanzees"), condensed structure, accurate meaning preserved, and includes citation showing the source of the information. Why distractor fails: Options A and C have no citations, making them plagiarism even if reworded - Option C is especially problematic as it only changes "make" to "create" while keeping everything else nearly identical. Option D lacks citation and merely rearranges the sentence structure without truly paraphrasing. Teaching strategy: Show paraphrasing checklist - Original: "Goodall's careful observations showed that chimpanzees make and use tools, which changed how scientists understood them." Student version B: "Goodall proved chimps use tools and it changed science (Britannica School, 2021)." Check: Different words? Yes (proved/showed, chimps/chimpanzees). Different structure? Yes (condensed to simpler form). Same meaning? Yes. Citation? Yes. Compare with failures: A and C look reworded but NO CITATION = plagiarism. C barely changes words (create/make) = too close. D rearranges without citation = still plagiarism. Practice showing students that paraphrasing requires BOTH significant rewording AND citation - missing either element is plagiarism. Have students paraphrase the same sentence multiple ways, always including citation.
Question 2
For the research project on Jane Goodall's work, which student note is plagiarism from Source A's excerpt?
- Goodall watched chimpanzees for many years and recorded their behaviors in the wild (Goodall Institute, 2022).
- Jane Goodall was born in England and later became a scientist who studied animals.
- Goodall "observed chimpanzees in the wild for decades" (The Jane Goodall Institute, 2022).
- Goodall observed chimpanzees in the wild for decades. (correct answer)
Explanation: This question tests CCSS.W.6.8 (gathering relevant information from multiple print and digital sources, assessing source credibility, quoting or paraphrasing properly while avoiding plagiarism, and providing basic bibliographic information). When researching, students must use sources properly: QUOTING = exact words in quotation marks with citation; PARAPHRASING = restating in own words with different structure AND citation; PLAGIARISM = copying without quotes/citation, paraphrasing too closely (word-swapping), or using ideas without credit; Basic CITATION includes author, title, source/publication, date. Source A states "Goodall observed chimpanzees in the wild for decades" and option D copies these exact words without quotation marks or citation, which is direct plagiarism. The correct answer D identifies plagiarism because it uses the source's exact words ("observed chimpanzees in the wild for decades") without quotation marks or any citation, demonstrating the most common form of plagiarism - copying text verbatim without giving credit. The other options avoid plagiarism: A properly paraphrases with different words ("watched" for "observed," "many years" for "decades," "recorded their behaviors") plus citation, B adds new information not from the source, and C properly quotes with quotation marks and citation - showing the three ways to use sources correctly. Teaching strategy: Create a plagiarism detection exercise where students identify copied phrases by comparing student notes to source texts, looking for exact word matches without quotes/citations. Practice the three acceptable options: (1) quote with "marks" and citation, (2) paraphrase in completely different words with citation, or (3) use only your own ideas/knowledge - emphasize there's no fourth option of using source words without credit.
Question 3
The student wants to use an exact sentence from a book about the human body. What should the student do to quote it properly?
Research question: What is the main job of the respiratory system?
Source (PRINT): Morris, Dr. Alan. The Human Body Systems. Greenleaf Press, 2022, p. 56. Type: expert book. Excerpt: "The respiratory system brings oxygen into the body and removes carbon dioxide." Credibility notes: doctor author; reputable publisher.
Student wants to copy that sentence into the report.
- Copy the sentence exactly, but do not cite it because it is a common fact.
- Put quotation marks around the sentence and add a citation with author and page number. (correct answer)
- Change two words and leave out the author's name so it becomes the student's writing.
- Use quotation marks but do not name the source in the report or bibliography.
Explanation: This question tests CCSS.W.6.8 (gathering relevant information from multiple print and digital sources, assessing source credibility, quoting or paraphrasing properly while avoiding plagiarism, and providing basic bibliographic information). When researching, students must use sources properly: QUOTING = exact words in quotation marks with citation. The student wants to use the exact sentence "The respiratory system brings oxygen into the body and removes carbon dioxide" from Dr. Morris's book. The correct answer shows proper quoting: put quotation marks around the sentence and add a citation with author and page number - this gives full credit to the original author while allowing use of their exact words. Why distractor fails: Option A copies exactly without citation, which is plagiarism regardless of whether information seems like common fact. Option C suggests changing two words to claim ownership, which is still plagiarism (word-swapping doesn't make it your writing). Option D uses quotation marks but omits source information, making it impossible for readers to verify or find the original. Teaching strategy: Demonstrate proper quoting step-by-step - (1) Copy exact words: The respiratory system brings oxygen into the body and removes carbon dioxide. (2) Add quotation marks: "The respiratory system brings oxygen into the body and removes carbon dioxide." (3) Add citation: "The respiratory system brings oxygen into the body and removes carbon dioxide" (Morris 56). Show complete sentence in report: According to Dr. Morris, "The respiratory system brings oxygen into the body and removes carbon dioxide" (56). Practice with different quote integration methods: Dr. Morris explains that "[quote]" (56). "[Quote]," states Dr. Morris (56). As noted in the textbook, "[quote]" (Morris 56). Emphasize that quotation marks AND citation are both required - marks show exact words, citation shows whose words. Create exercises where students identify missing elements in improper quotes and fix them.
Question 4
The student wrote, "Volcanoes form when magma rises through cracks in Earth's crust," after reading Smith's 2021 science book, but gave no credit. Did the student plagiarize?
- No, because facts about how nature works belong to everyone, so a source is not needed here.
- No, because the student learned the idea and then wrote it in a fresh sentence of their own.
- Yes, because the student used the author's idea without naming the source they read. (correct answer)
- Yes, because using a source at all always requires a direct quote wrapped in quotation marks.
Explanation: The student learned how volcanoes form from Smith's 2021 book, then wrote about it without giving Smith credit. That is plagiarism, because you must credit an idea you got from a source even if you put it in your own words. So the best answer is that the student used the author's idea without naming the source.
The choice saying nature facts belong to everyone is wrong: in research writing, if you learned an idea from a source, you cite it, even a science fact. The choice saying a fresh sentence makes it your own is wrong: changing the wording does not change whose idea it is, so it still needs a citation. The choice saying you always need a direct quote is wrong: you can paraphrase an idea, but you must still name the source; quotation marks are only for exact words. Each of these misses the key rule—credit the source whenever the idea came from it.
Question 5
For the research project, did the student plagiarize by copying this source without quotation marks or citation? Source: "Owls hunt mostly at night using quiet flight." Student: Owls hunt mostly at night using quiet flight.
- No, because the sentence is short and states a fact that most people already know.
- No, because the student used correct grammar and clear punctuation throughout.
- Yes, because the student used exact words without quotation marks or a citation. (correct answer)
- Yes, because the student changed the fact slightly but forgot to name the original source.
Explanation: The student wrote the source's sentence word-for-word, but added no quotation marks and named no source. That is plagiarism: whenever you use an author's exact words, you must both put them in quotation marks AND cite where they came from. The choice saying the student used exact words without quotation marks or a citation is correct because it names exactly what is missing. The choice about the sentence being short and well-known is wrong—"quiet flight" is the author's specific wording, not common knowledge everyone already shares. The choice about correct grammar and punctuation is wrong because neat writing has nothing to do with giving credit; you can copy perfectly and still plagiarize. The choice claiming the student changed the fact slightly is wrong because the student didn't change anything—the sentences match exactly, so this misreads the scenario. Remember: to use a source honestly, either quote it with marks and a citation, or reword it fully in your own way and still cite it.
Question 6
When evaluating sources about hurricanes and weather, which source is most appropriate and credible for current information?
- "Hurricane Tracker Live!" www.stormbuzz.com, written by "WeatherDude99," no credentials, lots of pop-up ads.
- A 2001 textbook chapter with no updates and no website link for new data.
- "Hurricanes." National Oceanic and Atmospheric Administration (NOAA.gov), updated August 2024, includes data and definitions. (correct answer)
- A short anonymous comment under a video saying hurricanes are "getting smaller every year."
Explanation: This question tests CCSS.W.6.8 (gathering relevant information from multiple print and digital sources, assessing source credibility, quoting or paraphrasing properly while avoiding plagiarism, and providing basic bibliographic information). When researching, students must ASSESS CREDIBILITY by evaluating author credentials (education, position, expertise), publication date (recent for current topics), publisher/website reputation (.edu/.gov more credible than random .com, established publishers/organizations), editorial oversight (peer-reviewed, fact-checked), sources cited by author, and objective vs biased tone. The sources include: (A) commercial site by "WeatherDude99" with ads, (B) 2001 textbook with no updates, (C) NOAA.gov updated August 2024 with data, and (D) anonymous video comment. The correct answer C identifies NOAA.gov as most credible based on government domain (.gov), recent update (August 2024 crucial for weather data), official weather agency expertise (National Oceanic and Atmospheric Administration), and inclusion of data/definitions - showing understanding that current weather information requires official, recently updated sources. The distractors fail because: A has no real credentials (username only) and commercial bias (pop-up ads), B is severely outdated (2001) for current weather patterns, and D is anonymous opinion without data - students must recognize that weather/climate information changes and requires current, official sources. Teaching strategy: Emphasize date importance for science topics - compare 2001 hurricane data with 2024 data to show how patterns change; teach recognition of official weather sources (NOAA, National Weather Service, NASA) versus informal sites. Create a checklist specifically for science sources: recent date (within 2-3 years for current events), official organization (.gov or established institution), actual data not just opinions, and author expertise in the specific science field.
Question 7
When evaluating sources about the American Revolution, which source is most credible?
- Lopez, Dr. Maria. "Taxes and Tension in the Colonies." Smithsonian Magazine (online), 2022, fact-checked article by a history writer. (correct answer)
- Brooks, Jordan. "The Revolution Was Totally Avoidable!" HistoryHotTakes.com, 2023, personal blog post sharing one fan's strong opinions.
- Reed, Sam. "Cool Revolution Facts." StudentProjectWiki.net, 2024, editable page anyone can change with no expert review.
- Carter, Alex. "Colonial Life Explained." PatriotDressUp.com, 2024, short history paragraph on a costume store's sales page.
Explanation: The best source is the Smithsonian Magazine article written by Dr. Maria Lopez. It has a named expert author, comes from a respected museum publisher, and was fact-checked before publishing, so you can trust its accuracy. Check the other options against those same tests. The HistoryHotTakes post is a personal blog sharing one person's opinion, with no editorial review or evidence backing up its bold claim—opinions alone are not reliable for research. The StudentProjectWiki page is editable by anyone at any time, and no expert checks the facts, so a mistake could sit there uncorrected. The PatriotDressUp paragraph appears on a store page whose real goal is selling costumes, not carefully teaching history, so it may be simplified or slanted to attract customers. Even when a source looks tidy, ask who wrote it, who publishes it, and whether it was reviewed. Only the Smithsonian article passes all three checks, making it the most credible choice.
Question 8
When evaluating sources about how vaccines protect against disease, which source has the strongest credibility indicators?
Research question: How do vaccines help the immune system prevent illness?
Source 1 (DIGITAL): "How Vaccines Work." Centers for Disease Control and Prevention, https://www.cdc.gov/vaccines, updated 2025, accessed May 2026. Type: .gov webpage. Excerpt: "Vaccines train the immune system to recognize and fight germs."
Source 2 (DIGITAL): "Vaccines Are a Trick!" www.healthfreedom-now.com, author 'TruthMom,' posted 2019, accessed May 2026. Type: opinion blog. Excerpt: "Doctors don't want you to know this."
Source 3 (PRINT): "Vaccines (1998)." Old health encyclopedia, 1998 ed., pp. 90-94. Type: reference book. Excerpt: "Some vaccine schedules differ from today."
Source 4 (DIGITAL): "Top 5 Vaccine Memes." Social media post, March 2026. Type: social media. Excerpt: "Share if you agree!"
- Source 2, because it is a recent digital source written by an author who feels strongly about the topic and warns readers about what others hide.
- Source 3, because it is a published reference book, and printed encyclopedias give more reliable medical facts than websites and blogs do.
- Source 4, because it is the most recent digital source, and a post that many people choose to share must contain information others have checked.
- Source 1, because it is a recent .gov source from a health agency with research-based information about the immune system. (correct answer)
Explanation: The best answer is the CDC page. A .gov site from a government health agency is reviewed by medical experts, it was updated in 2025, and it explains the science in an objective, research-based way—exactly what a current medical topic needs.
The opinion blog looks recent, but the author has no medical credentials, uses an emotional 'doctors are hiding this' tone, and lists no sources, so strong feelings are not the same as credibility. The printed encyclopedia is a real reference book, but its 1998 information is too old for medicine, which changes as research advances—being in print does not make it current or reliable. The meme post is recent and popular, but likes and shares are not fact-checking; popularity does not verify accuracy. Only the CDC source meets the true credibility tests of expert authorship, current date, and research support.
Question 9
The student found this source text: "Wolves help ecosystems by controlling deer numbers." Which student sentence is the best paraphrase with a citation?
- Wolves help ecosystems by controlling the deer numbers in an area (National Park Service, 2023).
- Wolves assist ecosystems because they keep deer populations from growing too large (National Park Service, 2023). (correct answer)
- Wolves benefit ecosystems by managing how many deer live in a region and helping other species survive.
- Wolves control deer numbers, and that clearly makes wolves the smartest animals (National Park Service, 2023).
Explanation: A good paraphrase does two things: it restates the source in your own words and structure, AND it gives credit with a citation. The best answer replaces "help" with "assist" and rewrites "controlling deer numbers" as "keep deer populations from growing too large," then adds a proper citation with source and year. That is a real restatement, not just copying. The choice that says wolves "control the deer numbers in an area" only shuffles a few words and keeps almost the exact original wording, so it is too close to be a true paraphrase even though it adds a citation. The choice about wolves managing deer and "helping other species survive" is worded well, but it drops the citation completely, so it fails to give the source credit—and it also adds an idea the source never states. The choice calling wolves "the smartest animals" sneaks in an opinion that is not in the source at all, so it is not an accurate paraphrase no matter how it is cited. Only one option truly rewords the idea AND cites it correctly, which is why it is the best answer.
Question 10
The student wrote: "The Great Wall is over 13,000 miles long" (World History for Kids). What is missing to make the citation complete?
- The author of the material and the publication date or year of the source. (correct answer)
- The page number where the fact appears and the total length of the book.
- The website address and the date the student first read the source.
- The library where the source was found and the reason it was chosen.
Explanation: A complete citation needs the basic pieces that let a reader find and check the source: the author, the title, the source or publisher, and the date it was published. This student only gave the source name, so the missing pieces are the author (write "No author" if none is named) and the publication date or year. The other choices name details that are not required parts of a citation. A page number can help for a direct quote, but the book's total length is never part of a citation. A website address may be included for a digital source, but the date you personally read it is not the publication date a citation calls for. The library building where you found the source and your personal reason for choosing it belong in notes or a report, not in the source citation itself. Only one choice names the two standard elements this citation is actually missing.
Question 11
For the research project on how vaccines protect against disease, which source is most credible to use and cite?
- "Vaccines Explained," by Dr. Lena Patel (immunology professor), on the U.S. Centers for Disease Control and Prevention site (CDC.gov), updated 2024; includes references and a fact-checked tone. (correct answer)
- "Understanding Immunity," by Jordan Miles (wellness writer), on the Daily Health News site (dailyhealthnews.com), updated 2023; includes a few links and an opinion-based tone.
- "How Vaccines Work," by the Riverbend Middle School Science Club, on their class blog (riverbendscienceclub.org), posted 2019; includes some notes and a friendly student tone.
- "The Science of Shots," by Alex Reed (medical products marketer), on the ImmunityPlus store site (immunityplus.com), updated 2024; includes product info and a persuasive sales tone.
Explanation: The best source to cite is the article by an immunology professor on the CDC.gov site. Its author has real expertise in the subject, the government health domain is trustworthy, it was updated recently, and it lists references and reads as fact-checked rather than personal or persuasive. The article by a wellness writer on a news site looks fairly solid, but the author has no medical expertise and the tone is opinion-based, so it is less reliable for scientific facts. The class-blog article is written by students, not experts, and it is several years old, so it may be outdated and lacks authority on medical science. The store-site article is recent and organized, but the author is a marketer trying to sell products, so the persuasive, sales-driven purpose makes it biased and untrustworthy for research. To choose well, weigh author expertise, the trustworthiness of the site, how current the information is, whether references are given, and whether the tone is neutral instead of persuasive or personal. Only the CDC source meets all of these credibility standards, which is why it is the strongest one to use and cite.
Question 12
When evaluating sources about vaccines, which detail best shows commercial bias that lowers credibility?
- The site was updated in 2023 and repeatedly urges readers to "Sign up now for our paid membership plan!"
- The site has many ads and links repeatedly urging readers to "Buy our immune booster to replace shots!" (correct answer)
- The author, who holds a medical degree, includes a discount code for the wellness products she personally sells online.
- The site lists its sources at the bottom and links only to studies funded by a government health agency.
Explanation: Commercial bias means a source's main purpose is selling something, so it may hide or twist information to boost sales. The best answer describes a page full of ads that repeatedly pushes readers to "Buy our immune booster to replace shots!"—it is directly selling a product as a substitute for vaccines, which badly undermines its credibility on this topic. The choice about urging readers to sign up for a paid membership does show a sales motive, but that fee is for site access, not for a product replacing vaccines, so it is a weaker sign of bias about the vaccine claims themselves. The author with a medical degree adds a discount code for products she sells, which is a sales pitch, but her real credentials still lend some trustworthy expertise, so this detail is not the clearest example of pure commercial bias. Listing sources and linking to government-funded studies is actually a sign of transparency and credibility, not bias, even though those studies received funding. Look for the detail whose whole purpose is selling a product that competes with the medical treatment being discussed—that is the strongest evidence of credibility-lowering commercial bias.
Question 13
To avoid plagiarism, which student sentence correctly quotes this source and cites it? Source: Beavers build dams to slow water and create deep pools (Nguyen, 2023).
- Beavers build dams to slow water and create deep pools. (Nguyen, 2023)
- "Beavers build dams to slow water and create deep pools" (Nguyen, 2023). (correct answer)
- "Beavers build dams to slow water and create deep pools" to make ponds.
- Beavers build dams that slow water and create deep pools (Nguyen, 2023).
Explanation: When you use a source's exact words, you need two things: quotation marks around those exact words AND the author and year in parentheses. The correct sentence does both — the exact words sit inside quotation marks and (Nguyen, 2023) follows right after, so credit is given and there is no plagiarism.
The sentence that copies the exact words but leaves off quotation marks looks like a quote because of the citation, but without quotation marks it reads as if those words are the student's own — that is plagiarism.
The sentence with quotation marks around the exact words but ending in "to make ponds" adds a citation-free personal comment and never names the source, so the reader can't tell where the borrowed words came from.
The last sentence changes "to" into "that" and adds a citation, but it still uses the source's exact wording without quotation marks. Because the words are basically copied, dropping the quotation marks makes it plagiarism, and it isn't a true paraphrase either since the words weren't put into new language.
Remember: exact words from a source always need both "quotation marks" and (Author, Year).
Question 14
The student found two digital sources about recycling. Which one is more credible to cite for facts, and why?
- A city government page (cityname.gov), updated 2023, with author contact information and data tables about local recycling. (correct answer)
- A news-style blog (recyclingnews.com), updated 2024, with a bold headline but no author name and no data behind its claims.
- An environmental group's page (savetheearth.org), updated 2019, with a mission statement urging readers to reduce plastic use.
- A store's tips page (greenbuys.com), updated 2024, with recycling advice placed right beside ads selling new plastic products.
Explanation: The city government page is the strongest choice for facts. It comes from an official source that actually runs the local recycling program, it is current (2023), it lists contact information so someone is accountable, and it backs its claims with data tables you can check. The news-style blog looks current and confident, but it hides its author and gives no data or sources, so you cannot verify anything it claims. The environmental group's page is from a real organization, but it is out of date (2019) and mainly promotes a cause instead of reporting checkable facts, so it may be biased. The store's tips page is recent, yet placing recycling advice next to ads for new plastic products shows a commercial motive that could shape the information. When you gather facts, favor a source that is official, current, accountable, and supported by data over ones that hide their author, push a message, or want to sell you something.
Question 15
The student copied this sentence from a website without quotes or a citation: "Owls can rotate their heads up to 270 degrees." Which statement best describes the problem?
- It is not plagiarism because the student changed the topic sentence and put the fact into a report in his own paragraph.
- It is plagiarism because the student used exact words without quotation marks or a citation naming the source. (correct answer)
- It is acceptable because the fact is true and can be checked, so the student does not need to name where it came from.
- It is fine because the information is common knowledge that anyone could find easily on many different websites.
Explanation: The student copied the sentence word for word from a website but added no quotation marks and no citation. Whenever you use someone else's exact words, you must show they are borrowed by putting quotation marks around them and naming the source. That is exactly why the choice pointing to missing quotation marks and a citation is correct.
The idea that it is okay because the student put the fact in his own paragraph is wrong—surrounding your own writing does not change the fact that the sentence itself is copied word for word. The claim that a true, checkable fact needs no source is also wrong; even accurate facts must be credited when you use the author's exact wording. Finally, calling it common knowledge does not help: this specific sentence, copied exactly, still needs quotation marks and a citation even if the information appears on many sites. Remember: exact words always need quotes plus a source.
Question 16
The student wrote a report about animal behavior. Which option shows the best paraphrase that avoids plagiarism and cites the source?
Research question: How do wolves communicate in a pack?
Source (DIGITAL): "Wolf Communication." Smithsonian's National Zoo, https://nationalzoo.si.edu/animals/wolf, updated 2024, accessed May 2026. Type: museum .org webpage. Excerpt: "Wolves communicate using body posture, facial expressions, scent marking, and a variety of vocalizations, including howls." Credibility notes: museum organization; updated; objective tone.
Student needs one sentence for the report.
- Wolves communicate using body posture, facial expressions, scent marking, and vocalizations, including howls.
- Wolves talk by posture, faces, scent marking, and many sounds like howls (Smithsonian's National Zoo, 2024).
- According to Smithsonian's National Zoo, "Wolves communicate using body posture, facial expressions, scent marking, and a variety of vocalizations, including howls" (2024).
- Wolves share messages in several ways, such as signals with their bodies, smells, and sounds (Smithsonian's National Zoo, 2024). (correct answer)
Explanation: This question tests CCSS.W.6.8 (gathering relevant information from multiple print and digital sources, assessing source credibility, quoting or paraphrasing properly while avoiding plagiarism, and providing basic bibliographic information). When researching, students must use sources properly: PARAPHRASING = restating in own words with different structure AND citation. The source states "Wolves communicate using body posture, facial expressions, scent marking, and a variety of vocalizations, including howls." Option D shows proper paraphrasing: "Wolves share messages in several ways, such as signals with their bodies, smells, and sounds" - completely reworded with different structure while maintaining meaning, plus citation (Smithsonian's National Zoo, 2024). The correct answer demonstrates all elements of proper paraphrasing: original wording ("share messages" instead of "communicate," "signals with their bodies" instead of "body posture"), different structure (grouped differently), maintains accurate meaning, and includes proper citation. Why distractor fails: Option A has no citation, making it plagiarism even though reworded. Option B barely changes words ("talk" for "communicate," "faces" for "facial expressions") - too close to original. Option C uses quotation marks making it a quote, not a paraphrase. Teaching strategy: Show paraphrasing process - Read original: "Wolves communicate using body posture, facial expressions, scent marking, and a variety of vocalizations, including howls." Put source away. Think: What's the main idea? (wolves have multiple ways to communicate). Write in own words: "Wolves share messages in several ways, such as signals with their bodies, smells, and sounds." Add citation: (Smithsonian's National Zoo, 2024). Check: Different words? Yes. Different structure? Yes. Same meaning? Yes. Citation included? Yes. Practice with students identifying why each option works or fails. Emphasize that paraphrasing requires BOTH restating in truly different words AND citing the source - missing either element is plagiarism.
Question 17
To avoid plagiarism in a report about ecosystems, did the student plagiarize the source text below?
Research question: How do decomposers help an ecosystem?
Source (PRINT): Kline, Deborah. "Decomposers." Science News for Students, Sept. 2023, pp. 18-19. Type: magazine article. Excerpt: "Decomposers break down dead plants and animals into simpler materials. These materials return to the soil and can be used again by producers." Credibility notes: fact-checked; author named; recent date.
Student sentence: Decomposers break down dead plants and animals into simpler materials that return to the soil and can be used again by producers.
- No, because the writer used the source only for a school report, so citing a magazine article is not required.
- Yes, because the writer used the source's exact words without quotation marks or a citation. (correct answer)
- No, because the writer combined two sentences into one, so it counts as paraphrasing the article.
- Yes, because the writer used a fact from a magazine, and facts must always be quoted directly.
Explanation: The student sentence matches the source almost word for word, joining the two original sentences with the word "that." Because those are the article's exact words, they need quotation marks AND a citation naming Kline. The student included neither, so this is plagiarism—that is the best answer.
The choice saying no citation is needed for a school report is wrong: academic honesty applies to all schoolwork, so a magazine source must still be credited. The choice calling this paraphrasing is wrong: simply combining two sentences and dropping a period is not restating the idea in your own words and structure—it is still copying. The choice claiming facts must always be quoted directly is wrong: once you cite a source, you may either quote it or paraphrase it in your own words; facts are not automatically off-limits.
To fix the sentence, the writer could quote it: "Decomposers break down dead plants and animals into simpler materials" (Kline 18). Or paraphrase it: Decomposers help ecosystems by turning dead matter into simple nutrients that plants can reuse (Kline 18). Either way, a citation is required.
Question 18
The student found this sentence: "Coral reefs support many fish by providing food and shelter." Which choice is the best paraphrase with a citation?
- Coral reefs support many fish by providing food and shelter. (ReefLife.org)
- Coral reefs help many fish survive because reefs offer places to hide and find meals (ReefLife.org). (correct answer)
- Coral reefs help fish by giving them food and shelter.
- Coral reefs provide food and shelter, so they support lots of fish (ReefLife.org), (ReefLife.org).
Explanation: This question tests CCSS.W.6.8 (gathering relevant information from multiple print and digital sources, assessing source credibility, quoting or paraphrasing properly while avoiding plagiarism, and providing basic bibliographic information). Students must use sources properly: QUOTING = exact words in quotation marks with citation; PARAPHRASING = restating in own words with different structure AND citation. The original sentence states "Coral reefs support many fish by providing food and shelter." The correct answer B successfully paraphrases by changing "support" to "help survive," restructuring to "because reefs offer," and replacing "providing food and shelter" with "places to hide and find meals" - all while maintaining the meaning AND including the required citation (ReefLife.org). Why distractors fail: Choice A merely swaps a few words ("support" to "help") but keeps the same structure, making it too close to the original; Choice C restates the idea but completely omits the citation, which is plagiarism even when paraphrasing; Choice D unnecessarily doubles the citation and awkwardly rearranges words without truly rephrasing the concept. Teaching strategy: Teach the read-cover-write method for paraphrasing: read the source, cover it up, write the idea in completely different words, then check accuracy and add citation. Show students that paraphrasing means explaining the same idea as if telling a friend, not just swapping synonyms. Practice with common mistakes: word-swapping isn't enough, citation is always required even for paraphrases, and the new version should sound natural. Create before/after examples showing original sentences transformed into proper paraphrases with different sentence structures.
Question 19
To cite a book correctly in a sixth-grade bibliography, what basic information should the student include for this source?
- The author's name, the title, and a short summary of the reader's opinion about the book.
- The author's name, the title, the publisher, and the year the book was published. (correct answer)
- The author's name, the title, the total number of chapters, and the price on the cover.
- The author's first name only, the title, and the page numbers the reader looked at.
Explanation: A correct book citation gives readers enough information to find and check the exact source. That means you need the author's name, the title, the publisher, and the year it was published. Together these four facts point to one specific book, so this is the right answer.
The choice that adds a reader's opinion is wrong because a citation lists facts about the source, not what someone thought of it, and it leaves out the publisher and year. The choice with the number of chapters and the cover price includes details that don't help anyone locate or verify the book, so those facts don't belong in a citation. The choice giving only the author's first name and the page numbers is incomplete: without the last name, publisher, and year, a reader can't tell which book you mean or find it in a library. Only the option with author, title, publisher, and year gives every fact needed to identify the source correctly.
Question 20
When evaluating sources about hurricanes, what credibility concern is strongest for a webpage with no author and no date on weatherfactsnow.com?
- It uses short paragraphs, so it must be written for kids and is therefore credible.
- It has no author or date, so the information cannot be checked for expertise or recency. (correct answer)
- It is a .com site, so it is always unreliable no matter what it says.
- It mentions hurricanes, so it is automatically relevant and does not need credibility checks.
Explanation: This question tests CCSS.W.6.8 (gathering relevant information from multiple print and digital sources, assessing source credibility, quoting or paraphrasing properly while avoiding plagiarism, and providing basic bibliographic information). When researching, students must ASSESS CREDIBILITY by evaluating author credentials (education, position, expertise), publication date (recent for current topics), publisher/website reputation (.edu/.gov more credible than random .com, established publishers/organizations), editorial oversight (peer-reviewed, fact-checked), sources cited by author, and objective vs biased tone. The webpage about hurricanes has no author and no date on weatherfactsnow.com - missing two critical credibility indicators that prevent verification of expertise and currency of information. The correct answer recognizes that without author or date, the information cannot be checked for expertise (is the author a meteorologist?) or recency (is this current hurricane data or outdated?), making it unreliable for research. The distractors show misunderstandings: thinking short paragraphs indicate credibility (A) confuses readability with reliability; believing all .com sites are unreliable (C) oversimplifies - some .com sites from established organizations can be credible; assuming topic relevance eliminates need for credibility checks (D) ignores that even relevant information must come from reliable sources. Teaching strategy: Use the credibility checklist systematically - start with Author (name? credentials?) and Date (when published? current for topic?), then check Publisher/Domain, Sources cited, and Tone. Show examples where missing author/date makes source unusable regardless of other factors. Practice with weather sources comparing National Weather Service (author credentials, current date) versus anonymous weather blogs (no author, no date). Emphasize that BOTH author AND date are essential - without them, students cannot verify if information comes from an expert or if it's current enough to be accurate.
