Research different aspects of a topic, record observations and write an informative report

Learning goal: This lesson teaches Ohio's 2026 standards W.5.2 and W.5.7, first implemented in 2027-28. You will engage in an independent research project that investigates different aspects of a topic by using multiple sources on a topic, recording observations and composing a short report using grade-level vocabulary and sentence variety. Your report is an informative/explanatory piece that includes an introduction with a clear topic and focus; facts, definitions, concrete details, quotations and examples to develop the topic; a concluding statement; an organizational structure to support the writer's purpose; linking words, phrases and clauses; precise language and domain-specific vocabulary; sentence variety; and grade-level spelling.

Topic, aspects and focus. A topic is broad: earthworms. An aspect is one part of the topic you can investigate: what earthworms eat, how their tunnels change soil, what conditions they need. The focus is the main point your report makes about the topic: Common garden earthworms can improve garden soil in ways gardeners can see. Dividing a topic into aspects gives your research a plan and your report its organizational structure: one section per aspect.

Multiple sources. An independent research project uses more than one source because each source gives only part of the picture and because checking one source against another catches mistakes. Useful sources for a fifth grader include a library book, a website approved by your teacher (for example, one from a university, a museum or a government science agency), an interview with someone who knows the subject, and your own observations. Record each source as you use it: title, author or organization, and for websites the address and date you visited.

Recording observations. An observation is what you notice with your senses, recorded right away, with the date. It is different from an interpretation. "Day 3: two new tunnels along the glass, one reaching the middle sand layer" is an observation. "The worms are happy" is an interpretation that the observation does not show. Observations become concrete details in your report.

Developing the topic. An informative report uses five kinds of support. Facts are statements that can be checked. Definitions explain terms a reader may not know. Concrete details are specific, often from observation. Quotations are exact words from a source, in quotation marks, with the speaker or source named. Examples show a general point in a specific case.

Grade-level spelling in a report. A report repeats its topic words, so spell them correctly the first time. Copy domain-specific words exactly from your source or its glossary (castings, burrows, nutrients). Spell longer words by their parts: earth + worm = earthworm; decay + -ing = decaying, keeping the y because a vowel comes before it; moist + -ure = moisture. Check any word you are unsure of in a print or digital dictionary before you publish.

Complete original model — Underground Farmers: How Earthworms Can Improve Garden Soil

The sources named in this model are invented for the lesson so that no quotation is falsely attributed. Your report must use real sources.

Introduction. Most people see earthworms only after a rainstorm, stranded on a sidewalk. Underground, however, earthworms do important work. In a garden, common earthworms can improve soil by eating dead plant material, digging tunnels and mixing soil layers, and they can do this only when conditions are right.

What earthworms eat. Earthworms feed on decaying plant material, such as fallen leaves, along with the soil around it. After food passes through a worm's body, the worm leaves behind castings, which are worm waste. Castings are rich in nutrients, the substances plants need to grow. As a result, a garden with many worms has soil that is being fed from below. According to Ms. Patel, a gardener at our community garden, "When I find lots of worms, I know that bed will grow good tomatoes."

How tunnels change soil. As earthworms move, they dig tunnels called burrows. These burrows let air and rainwater move down into the soil, where plant roots can reach them. For example, in our class worm jar, the worms tunneled through all three layers within a week. On Day 1, the layers of dark soil, light sand and dark soil were separate. By Day 7, sand streaked down into the bottom soil layer along four tunnels we could see through the glass.

What earthworms need. Earthworms need moist soil because they breathe through their skin, which must stay damp. They avoid light and heat. The book Life Underground explains that a worm "dries out quickly if it stays on a hot surface," which is one reason worms stranded on a sidewalk after rain are in danger. We kept our jar covered with dark paper and misted the soil every other day.

Conclusion. Earthworms rarely get credit, but by recycling leaves, opening tunnels and mixing soil, they act like underground farmers. Gardeners who keep soil moist and covered with leaves are helping the helpers that help their plants. Not every earthworm helps everywhere, though: in some northern forests, earthworms that arrived from other places eat the leaf layer that native plants need, and a kind called the jumping worm can damage garden soil. This report is about common earthworms in a garden.

How the model meets the standard. The introduction states the topic (earthworms) and focus (in a garden they can improve soil). The structure uses one section per aspect, with headings, which supports the purpose of explaining. It includes facts (worms breathe through their skin), definitions (castings, burrows, nutrients), concrete details from observation (four tunnels by Day 7), a quotation from an interview and a quotation from a book, and examples (the worm jar). Linking words and phrases (however, as a result, for example, because, which is one reason) connect ideas. Domain-specific vocabulary (castings, burrows, nutrients, decaying) is precise. Sentences vary in length and structure. The conclusion returns to the focus in its first sentence, which gathers the three aspects (recycling leaves, opening tunnels, mixing soil), and then states a limit of the report. Topic words such as castings and burrows are spelled the same way every time.

A safe investigation you can do. Materials: a large clear plastic jar, moist garden soil, sand, a few dead leaves, dark paper, a spray bottle, and three to five earthworms gathered from a garden with an adult. Steps: layer soil, sand and soil; add the worms and leaves on top; wrap the jar in dark paper; keep it cool and mist the soil every other day. Record: each day, remove the paper briefly, observe, sketch the tunnels and count visible tunnels. What supports the claim: sand mixing into soil along tunnels shows the worms mixed layers. After one to two weeks, return the worms to the place you found them. Wash your hands after handling soil and worms. The jar is a model: it shows mixing and tunneling, but it cannot show how many worms live in a real field or how fast a whole garden changes.

A misconception to avoid. A report is not a pile of facts copied in order from one book. It is your explanation, organized by your aspects, using several sources, in your own words except where you quote.

Worked example 1 — From notes to a paragraph. Notes: (book) "worms breathe through skin, need moisture"; (observation, Day 4) "top soil dry, worms deeper"; (interview) "Water before you dig; worms come up." Paragraph: "Earthworms need moist soil because they breathe through their skin. On Day 4, when the top of our jar had dried out, we saw that the worms had moved deeper, where the soil was still damp." The fact comes from one source and the concrete detail from another; the linking word because and the clause when the top of our jar had dried out connect them.

Worked example 2 — Quoting correctly. Weak: Worms dry out quickly on hot surfaces (with no source and presented as if the words were the writer's own). Strong: The book Life Underground explains that a worm "dries out quickly if it stays on a hot surface." The exact words are in quotation marks, the source is named, and the book title is in italics.

Worked example 3 — Sentence variety in a report. Draft: "Worms eat leaves. Worms leave castings. Castings have nutrients. Plants need nutrients." Revised: "Worms eat decaying leaves and leave behind castings. Because castings are rich in nutrients, plants growing nearby are fed from below." The revision uses a compound predicate and a complex sentence, keeps the domain-specific words and shows the cause-and-effect relationship.

Representation task — research organizer. Make a four-part organizer: (1) topic, focus and three aspects written as questions; (2) a source list with at least three sources of at least two different kinds (book, approved website, interview, observation); (3) a dated observation log with at least five entries; (4) a note chart with one column per aspect, each note labeled with its source.

Independent performance. Choose a topic from science or social studies that you can observe in some way (plants on a windowsill, birds at a feeder, traffic at a crosswalk counted with an adult). Investigate three aspects and write a short report of four to six paragraphs with headings.

Success criteria: Your introduction states the topic and a clear focus. You use at least three sources of at least two kinds, listed at the end, and at least one set of dated observations. Each section develops one aspect with facts, at least one definition, concrete details from your observations, at least one quotation with its source named, and an example. You use domain-specific words correctly and linking words, phrases and clauses between ideas. Your sentences vary in length and structure. Your conclusion returns to the focus. Grade-level words are spelled correctly, and your notes show which source each fact came from.
