7th Grade Writing › Develop Topic With Relevant Information
A student is explaining how photosynthesis works but has only written: "Plants make food." What type of information would best develop the topic next?
A list of the student’s favorite fruits and vegetables.
A description of how to paint a landscape with trees.
A personal story about a time the student watered a plant.
A definition of photosynthesis plus key facts about inputs and outputs (for example, plants use carbon dioxide and water with sunlight to produce glucose and oxygen).
Explanation
This question tests developing informational/explanatory topics with relevant facts (specific data, verified statements), definitions (precise explanations of terms/concepts), concrete details (specific descriptive information), quotations (expert statements, source material), and examples (specific instances illustrating general principles)—information types that build reader understanding. The draft "Plants make food" is overly simplified and needs scientific explanation to develop the topic of photosynthesis effectively. Option A correctly suggests adding a definition of photosynthesis plus key facts about inputs (carbon dioxide, water, sunlight) and outputs (glucose, oxygen), which would transform the vague statement into a clear scientific explanation. Option B offers an irrelevant personal anecdote, Option C lists food preferences unrelated to the process, and Option D discusses painting rather than plant biology. Strong informational writing about scientific processes requires precise definitions, identification of key components, and explanation of how inputs transform into outputs, helping readers understand complex biological processes through specific, accurate information rather than oversimplified statements.
A student is writing about earthquakes and includes these details: (1) "Earthquakes happen when stress builds up along faults." (2) "Seismic waves carry energy through the Earth." (3) "My cousin felt scared during an earthquake last year." (4) "Scientists measure earthquake size using magnitude." Which choice best identifies the weakness in how the topic is developed?
The paragraph is inaccurate because faults are only found in the ocean.
The paragraph includes an irrelevant personal anecdote that doesn’t explain how earthquakes work.
The paragraph has no facts at all about earthquakes.
The paragraph uses too many statistics and should remove all scientific terms.
Explanation
This question tests developing informational/explanatory topics with relevant facts (specific data, verified statements), definitions (precise explanations of terms/concepts), concrete details (specific descriptive information), quotations (expert statements, source material), and examples (specific instances illustrating general principles)—information types that build reader understanding. The paragraph contains three relevant scientific facts about earthquakes (stress along faults, seismic waves, magnitude measurement) but includes one piece of information that doesn't develop the topic of how earthquakes work—a personal anecdote about the cousin's fear. Option A correctly identifies this weakness: while the emotional experience is real, it doesn't explain earthquake mechanics or provide factual information about the phenomenon itself. The correct answer recognizes that personal anecdotes, while potentially engaging, don't develop informational topics unless they illustrate a factual point about the subject. Options B and C mischaracterize the paragraph (it does include facts and scientific terms appropriately), while option D makes a false claim about fault locations. When developing informational topics, students should distinguish between relevant facts that explain the topic and personal stories that, while interesting, don't contribute to reader understanding of the subject matter.
A student is writing about daily life for medieval peasants. Which set of concrete details would be most effective for developing the topic?
Peasants usually woke before dawn to feed animals, carried water in buckets, and worked fields from sunrise to sunset during planting and harvest. Many families lived in one-room homes with thatched roofs, cooked over a hearth, and slept on straw-filled bedding.
Medieval life was different from today, and people had a lot to do.
Many peasants lived in small villages and often worked outside.
Most peasants owned large castles and spent afternoons studying at universities.
Explanation
This question tests developing informational/explanatory topics with relevant facts (specific data, verified statements), definitions (precise explanations of terms/concepts), concrete details (specific descriptive information), quotations (expert statements, source material), and examples (specific instances illustrating general principles)—information types that build reader understanding. Concrete details bring historical topics to life by providing specific, sensory information that helps readers visualize and understand daily experiences. Option C excels by including multiple specific details: wake times (before dawn), daily tasks (feeding animals, carrying water in buckets), work schedules (sunrise to sunset), living conditions (one-room homes, thatched roofs), and domestic life (cooking over hearth, straw bedding)—all accurate historical details about peasant life. The correct answer develops the topic through vivid, specific details that create a complete picture of daily routines and living conditions. Options A and B are too vague and general, while option D contains historical inaccuracies (peasants didn't own castles or attend universities). To develop topics effectively with concrete details, students should include specific actions, objects, times, and sensory information that help readers understand exactly what life was like, rather than making broad generalizations.
A student is writing an informational paragraph about the water cycle. Which option provides the most relevant and specific facts to help develop the topic for 7th graders?
Most of Earth is covered by water, and many tourists enjoy visiting beaches in summer.
Water evaporates only when it reaches $0^\circ$C, and condensation happens when air gets warmer.
Water is important for life, and people should try not to waste it at home.
The water cycle includes evaporation (liquid water turning into water vapor), condensation (water vapor cooling into tiny droplets that form clouds), and precipitation (water falling as rain, snow, sleet, or hail). The Sun provides energy for evaporation, and gravity pulls precipitation back to Earth, where water collects in rivers, lakes, oceans, and groundwater.
Explanation
This question tests developing informational/explanatory topics with relevant facts (specific data, verified statements), definitions (precise explanations of terms/concepts), concrete details (specific descriptive information), quotations (expert statements, source material), and examples (specific instances illustrating general principles)—information types that build reader understanding. When writing about the water cycle, students need specific scientific facts that explain how the process works, not general statements about water or incorrect information. Option B provides comprehensive facts about all three stages of the water cycle (evaporation, condensation, precipitation), explains the role of the Sun and gravity, and describes where water collects—all relevant details that help readers understand this natural process. The correct answer effectively develops the topic by including specific terminology, explaining each stage clearly, and showing how the parts connect as a system. Option A is too general and doesn't explain the cycle itself, while option D contains factual errors (water evaporates at various temperatures, not just 0°C). To develop informational topics effectively, students should include specific facts and processes that directly explain their subject, avoiding both overly general statements and inaccurate information.
A student is writing an informational paragraph about earthquakes. The paragraph includes these sentences: (1) "Earthquakes happen when stress builds up along faults in Earth's crust." (2) "They can cause shaking that damages buildings." (3) "Earth is the third planet from the Sun." Which choice best identifies the weakness in how the topic is developed?
The paragraph should remove sentence (1) because it is too specific to be useful.
Sentence (3) is true but irrelevant; it does not help explain earthquakes or their causes and effects.
The paragraph uses too many technical terms and needs more opinions.
The paragraph is weak because it includes a cause and an effect instead of only one type of information.
Explanation
This question tests developing informational/explanatory topics with relevant facts (specific data, verified statements), definitions (precise explanations of terms/concepts), concrete details (specific descriptive information), quotations (expert statements, source material), and examples (specific instances illustrating general principles)—information types that build reader understanding. Effective topic development requires that all information directly relates to the main topic; irrelevant facts, even if true, weaken the explanation by distracting from the central focus. The paragraph appropriately includes information about earthquake causes (stress along faults) and effects (building damage), but sentence 3 about Earth being the third planet has no connection to earthquakes. Option B correctly identifies that sentence 3 is irrelevant because Earth's position in the solar system doesn't help explain earthquakes, their causes, or their effects. Option A incorrectly criticizes technical terms (which are appropriate for scientific topics), while option D wrongly suggests including both causes and effects is problematic. When developing informational topics, ensure every sentence contributes to explaining your specific subject; remove any information that, while factually correct, doesn't advance reader understanding of the topic at hand.
A student is developing an informational article about renewable energy. Which set of examples best supports the topic by showing clear, specific instances of renewable energy sources?
Solar panels on rooftops, wind turbines in open plains, and hydroelectric dams generating electricity from moving river water.
Coal power plants and gasoline engines because they are used in many places.
Energy is important, and people should try to use less of it.
Cars, phones, and video games that use electricity.
Explanation
This question tests developing informational/explanatory topics with relevant facts (specific data, verified statements), definitions (precise explanations of terms/concepts), concrete details (specific descriptive information), quotations (expert statements, source material), and examples (specific instances illustrating general principles)—information types that build reader understanding. Effective examples in informational writing must directly illustrate the concept being explained and show clear instances of the topic. Option A provides three distinct examples of renewable energy sources—solar panels (sun energy), wind turbines (wind energy), and hydroelectric dams (water energy)—each example specifically demonstrates a different type of renewable energy. The correct answer uses relevant examples that develop the topic by showing concrete instances of renewable energy sources in action. Option B lists energy users rather than sources, Option C incorrectly identifies non-renewable sources, and Option D offers general statements without examples. When developing topics with examples, choose specific instances that clearly demonstrate the concept, show variety within the category, and help readers recognize similar instances in their own experience.
A student includes the following sentence in an informational paragraph about photosynthesis: “Plants eat sunlight to make food, and the process happens mostly at night.” Which weakness in topic development does this sentence show?
It is relevant but needs more opinions to be convincing.
It is an expert quotation, so it does not belong in informational writing.
It is too specific and includes unnecessary numbers and measurements.
It is inaccurate, which can confuse readers about how photosynthesis works.
Explanation
This question tests developing informational/explanatory topics with relevant facts (specific data, verified statements), definitions (precise explanations of terms/concepts), concrete details (specific descriptive information), quotations (expert statements, source material), and examples (specific instances illustrating general principles)—information types that build reader understanding. Accuracy is essential when developing informational topics because incorrect information confuses readers and undermines the text's credibility. The sentence contains two major errors: plants don't "eat" sunlight (they use it for chemical reactions), and photosynthesis happens during daylight, not at night—these inaccuracies would mislead readers about this fundamental biological process. The correct answer identifies that inaccurate information weakens topic development by confusing readers about how photosynthesis actually works. Option A incorrectly suggests specific details are problematic, Option C misunderstands the role of expert information, and Option D confuses informational writing with persuasive writing. When developing scientific topics, verify all facts for accuracy, use precise scientific language, and ensure information aligns with established scientific understanding to maintain credibility and reader trust.
A student is writing an informational paragraph about recycling and includes these points: (1) “Recycling turns used materials into new products.” (2) “Many communities collect paper, plastic, glass, and metal in bins.” (3) “Recycling can reduce landfill waste.” Is the topic developed sufficiently for a short 7th-grade paragraph?
Yes, because it includes a joke, which makes any topic fully developed.
No, because it should only include one sentence to avoid giving too much information.
Yes, because the paragraph includes a clear definition and several relevant details about how recycling works and why it matters.
No, because it does not include a personal opinion about whether recycling is fun.
Explanation
This question tests developing informational/explanatory topics with relevant facts (specific data, verified statements), definitions (precise explanations of terms/concepts), concrete details (specific descriptive information), quotations (expert statements, source material), and examples (specific instances illustrating general principles)—information types that build reader understanding. A well-developed informational paragraph includes a clear definition, specific examples, and explanation of significance—all present in this student's work. The paragraph provides a definition of recycling, concrete examples of recyclable materials, and explains an environmental benefit, creating a complete informational unit appropriate for 7th grade. The correct answer recognizes that the paragraph uses relevant definition and details that develop the topic sufficiently for a short informational piece. Option B incorrectly requires personal opinion in informational writing, Option C wrongly limits paragraph length, and Option D confuses entertainment with development. For 7th-grade informational writing, a paragraph is sufficiently developed when it includes a clear definition or explanation, specific supporting details or examples, and connection to broader significance or impact.
A student is developing a paragraph about the causes of the American Dust Bowl. Which fact is most relevant for developing this specific topic?
The United States has 50 states, and many people live in cities along the coasts.
Many farmers felt sad when they had to move away, and it was a hard time emotionally.
During the 1930s, severe drought combined with poor farming practices (like deep plowing that removed native grasses) left topsoil loose and easy for winds to blow away.
Corn and wheat are popular foods that can be cooked in many different ways.
Explanation
This question tests developing informational/explanatory topics with relevant facts (specific data, verified statements), definitions (precise explanations of terms/concepts), concrete details (specific descriptive information), quotations (expert statements, source material), and examples (specific instances illustrating general principles)—information types that build reader understanding. When explaining the causes of the Dust Bowl, students need facts that directly address what created this environmental disaster. Choice A provides specific, relevant causes: severe drought combined with poor farming practices (deep plowing that removed native grasses), explaining how these factors made topsoil vulnerable to wind erosion—directly addressing the topic of causation. The correct answer develops the topic by providing specific historical and environmental factors that caused the Dust Bowl. Choice B offers general U.S. geography facts (unrelated to Dust Bowl causes), Choice C discusses food preparation (irrelevant), and Choice D focuses on emotional impact rather than causes. Effective topic development requires selecting information that directly addresses the specific aspect being explained—in this case, causes rather than effects or unrelated information.
A student is developing an informational report about renewable energy sources. Which choice provides the best examples that clearly illustrate the topic?
Examples of renewable energy include solar panels that turn sunlight into electricity, wind turbines that generate power from moving air, and hydroelectric dams that use flowing water to spin turbines.
Oil and gasoline are popular fuels used for transportation.
Energy comes from many places, including batteries and outlets.
Renewable energy is important, and people should use it more.
Explanation
This question tests developing informational/explanatory topics with relevant facts (specific data, verified statements), definitions (precise explanations of terms/concepts), concrete details (specific descriptive information), quotations (expert statements, source material), and examples (specific instances illustrating general principles)—information types that build reader understanding. When explaining renewable energy sources, writers need specific examples that clearly illustrate what these sources are and how they work. Option C provides three concrete examples with explanations: solar panels converting sunlight to electricity, wind turbines generating power from moving air, and hydroelectric dams using flowing water to spin turbines—each example shows both the source and the conversion process. Option A offers only a general opinion, Option B mentions non-renewable sources (batteries, outlets), and Option D incorrectly discusses fossil fuels rather than renewable sources. Strong informational writing uses multiple specific examples to help readers understand abstract concepts, with each example clearly connected to the main topic and explained in enough detail to build understanding.
