Conduct a short research project with credible sources, honest citation and writing over long and short time frames

Learning goal: Conduct a short research project to answer a question, including a self-generated question, drawing on several sources and generating additional related, focused questions that allow multiple avenues of exploration; gather relevant information from multiple print and digital sources using search terms effectively; assess the credibility and accuracy of each source; quote or paraphrase the data and conclusions of others while avoiding plagiarism and following a standard citation format; draw evidence from informational texts to support analysis, reflection and research; and write routinely over extended and shorter time frames for a range of discipline-specific tasks, purposes and audiences.

A short research project in a history, science or technical class is a bounded inquiry: one question, several sources, a week or two, a written answer. It is not a report that copies an encyclopedia entry under a new title. The difference lies in the question, which must be one the writer chose and cannot answer without reading, and in the handling of sources, which must be honest about where every fact and every phrase came from.

Generate a question, then generate more. A self-generated research question comes from something the writer noticed and could not explain. In the pendulum unit, a student who saw that length changed the period might ask: How did clockmakers use pendulums to keep time before electricity? That question is focused enough to answer and open enough to need several sources. As the reading begins, it should produce related, focused questions that open multiple avenues: How long is the pendulum in a clock that ticks once per second? What happens to a pendulum clock when the temperature changes and the rod expands? Why do ships' clocks not use pendulums? Each of these can be pursued separately, and the writer chooses the avenues the time allows. A project that ends with one answered question and two well-formed unanswered ones has done its job.

Gather from multiple print and digital sources with effective search terms. Distinctive keywords and specific phrases usually give tighter results than a loose sentence: "how did old clocks work" returns everything; "pendulum clock escapement history" returns sources about the mechanism. A natural-language question can work too, especially on engines built to read one, so the rule is not a ban on sentences but a habit: start with the most specific terms you have, look at what comes back, and refine. Add a place or a period to narrow: "pendulum clock 1600s". Put an exact phrase in quotation marks to require it. Many search engines let the writer exclude a word with a minus sign or restrict results to one site or domain; check the help page of the engine you use, because the syntax differs. Print sources still matter: a library's physics reference or a museum catalog often gives exact figures a web page copied without saying so. Aim for at least three sources of different kinds: for instance, a reference article, a museum or university page, and a book chapter.

Assess credibility and accuracy. Credibility is a judgment about the source; accuracy is a judgment about a particular claim in it. For credibility, ask: who wrote this, and what qualifies them? Who published it, and what is the publisher's purpose (to inform, to sell, to persuade)? When was it written or updated? Does it cite its own sources? For accuracy, check a specific claim against a second, independent source; if two sources give different numbers, note both and say which you trust and why. A page that names no author, gives no date and cites nothing may still be right, but the writer cannot show that it is, so its claims need a second source or they are left out.

Quote or paraphrase without plagiarism, and cite in a standard format. A quotation copies the source's exact words inside quotation marks with a citation. A paraphrase restates the source's information in the writer's own words and sentence structure, still with a citation, because the information belongs to the source even when the words do not. Plagiarism is presenting someone else's words, data or conclusions as your own, and it includes the disguised paraphrase that changes a few words but keeps the source's sentences. The test is simple: cover the source, write the idea from memory in your own way, then check the facts against the source. A standard citation format lists the same elements in the same order with the same punctuation every time, so a reader can find the source. This lesson teaches one such format, MLA, as used for a works-cited list and for in-text citations; your class may assign another, such as APA or Chicago, and the same elements will then appear in a different order with different punctuation. Follow the assigned format's punctuation exactly rather than inventing your own, and cite every source you drew evidence from, whether you quoted it or paraphrased it.

A works-cited entry in MLA form. The elements come in this order: the author (last name, first name) followed by a period; the title followed by a period; then the publication details, separated by commas and ending with a period. The title of a whole book is in italics. A page or article inside a larger work has its own title in quotation marks, followed by the larger work's title in italics. For a web page the date is written day, abbreviated month, year (May, June and July are not abbreviated), and the address comes last. The four entries below are models; the first three describe an invented book, museum and site, so that no reader mistakes them for real sources, and the fourth is this lesson's own article, which has no named author.

The list is headed Works Cited and is in alphabetical order by the first word of each entry, ignoring A, An and The; an entry with no author is alphabetized by its title.

An in-text citation in MLA form points from a sentence to one entry in the list. It sits in parentheses before the sentence's final period and holds the least that identifies the entry: the author's last name and the page number for a print source (Okafor 42); the author's last name alone for a source with no page numbers, such as this model web page (Lindqvist); when an online source does number its pages or paragraphs, use the locator it supplies if the assigned format calls for one; a shortened title in quotation marks when there is no author ("Seconds Pendulum"; "How a Pendulum"). If the sentence already names the author, the parentheses hold only the page number, or nothing for an unpaginated source. Every in-text citation must match the first word of an entry in the list, and every entry must be cited at least once.

Draw evidence from informational texts. Research writing supports its analysis with evidence from the texts read: a figure, a quoted sentence, a paraphrased conclusion. Each piece of evidence is followed by the writer's analysis, which says what it shows about the question, and the project ends with reflection, which says what the writer now understands, what surprised them and what remains open. Evidence without analysis is a list; analysis without evidence is an opinion.

Original informational article — How a Pendulum Keeps Time (written for this lesson as a practice source; treat it as a source to quote and paraphrase, not as a reference to cite elsewhere).

A pendulum keeps time because the period of its swing depends almost entirely on its length. For small swings, a pendulum about 99 centimeters long completes one swing, out and back, in very nearly two seconds, so each half-swing takes one second. A clock built around such a pendulum ticks once per second, which is why the "seconds pendulum" became a standard for clockmakers.

Left to itself, a pendulum swings a little less each time and eventually stops, because friction at its support and air resistance drain its energy. A clock therefore includes an escapement, a toothed wheel and a rocking piece that, once each swing, lets the wheel advance one tooth and gives the pendulum a small push. The push replaces the lost energy, and the escaping tooth moves the hands. The weight or spring that drives the wheel supplies the energy; the pendulum only regulates how fast it is released.

Because the period depends on length, anything that changes the rod's length changes the clock's rate. A metal rod expands slightly when warmed, so a pendulum clock tends to run slow in warm weather and fast in cold. Clockmakers answered this with rods made from materials that expand very little, or with compensating designs that use two metals so that one expansion cancels another.

A pendulum also needs a steady support. On a rolling ship, the swing is disturbed by the ship's own motion, so pendulum clocks kept poor time at sea; ships came to rely on spring-driven timekeepers regulated by a balance wheel instead. On land, in a case fixed to a wall, the pendulum's steadiness made pendulum clocks the standard for accurate timekeeping from the first one, built in 1656, until quartz clocks, developed from the 1920s onward, surpassed them.

Using the article honestly. A quotation: The article states that in a pendulum clock "the pendulum only regulates how fast it is released" ("How a Pendulum"). A paraphrase: According to the article, the driving weight supplies the clock's energy, while the pendulum controls the rate at which the escapement lets that energy out ("How a Pendulum"). Both citations point to the works-cited entry above, by its shortened title because it has no author. A disguised paraphrase that would count as plagiarism: The weight or spring that runs the wheel gives the energy; the pendulum just regulates how quickly it is let out. That version keeps the source's sentence and swaps a few words. It has two honest repairs: restore the source's exact words inside quotation marks and cite them, or rewrite both the wording and the sentence structure and cite the paraphrase. Putting quotation marks around the altered version would be a second error, because it would present words the source never used as the source's own.

Writing routinely over extended and shorter time frames. Research writing is not one long sitting. Over an extended time frame of one to two weeks, the project moves through a question, a source log, notes, a draft, a conference, revision and a final version, with time for reflection between stages. Within that frame, shorter pieces are written in a single sitting: a source evaluation in ten minutes, a paragraph of analysis on one piece of evidence, a two-sentence reflection at the end of a session, a summary of a reading for the next day. Each short piece has its own discipline-specific task, purpose and audience: a source log is for the writer, a summary may be for a partner, the final answer is for the teacher or the class. Writing often, in both frames, is what makes the long piece possible.

Worked question refinement: A student's first question is "Tell me about clocks." It is a topic, not a question, and it has no end. Refined: "How did pendulum clocks keep accurate time before electricity?" Now it can be answered. Reading the model article produces related, focused questions: "How long is a seconds pendulum?" (answerable with one figure), "How did clockmakers handle temperature?" (answerable with a paragraph), "Why not at sea?" (answerable with a comparison to balance wheels). The student chooses two avenues for a one-week project and lists the third as a question for later.

Worked search-term sequence: Search 1: "how do old clocks work" gives general pages and products. Search 2: "pendulum clock escapement" narrows to the mechanism. Search 3: "pendulum clock temperature compensation" targets the second avenue. Search 4 adds a period, "pendulum clock 1600s", to find historical sources. Each search records the terms used and the two best results in the source log, so the project can be retraced and so the writer notices when three pages all copy the same paragraph from one another.

Worked credibility comparison: Source 1 is a museum's page on its clock collection, with a named curator, a date and references. Source 2 is an anonymous page with no date that sells reproduction clocks. Source 3 is a physics textbook chapter. Source 1 and Source 3 are credible for different things: the museum for the history of particular clocks, the textbook for the physics of the period. Source 2 might be accurate, but nothing on it lets the writer show that, so any figure taken from it must be confirmed by Source 1 or 3, or dropped. When Source 2 gives a seconds-pendulum length of "one meter" and the textbook gives about 99 cm, the writer uses the textbook figure and notes that the round number is an approximation.

Worked evidence-and-analysis paragraph: Evidence: The model article states that a metal rod "expands slightly when warmed, so a pendulum clock tends to run slow in warm weather" ("How a Pendulum"). Analysis: This connects the pendulum unit's finding, that a longer pendulum has a longer period, to a real problem: a warmer rod is a longer rod, so each swing takes slightly longer and the clock falls behind. Reflection: Before the reading, the writer had assumed a clock's accuracy depended on how well it was built, not on the weather; the evidence shows that accuracy depended on physics the builder had to design around. The paragraph draws evidence from the text, analyzes it and reflects, in that order, and the in-text citation ("How a Pendulum") points to the works-cited entry for the article.

Source log task: Choose a self-generated question from your current science or history unit and approve it with your teacher. Over three sessions, keep a source log with columns for search terms used, source found (author, title, publisher or site, date, address), credibility notes (author, purpose, date, citations) and one fact recorded either as an exact quotation marked Q or as your own paraphrase marked P, with its source. Gather at least three sources of at least two kinds (print and digital). Write two related, focused questions that the reading raised and note which one you will pursue and which you will leave for later.

Citation task: Using the MLA form taught in this lesson, write a works-cited entry for each source in your log and one sentence that quotes or paraphrases each, with its in-text citation. Exchange with a partner who checks three things against the models: the order of the elements, the punctuation, and that every in-text citation matches the first word of an entry.

Independent performance: Over an extended time frame of two weeks, complete a short research project of 500 to 700 words answering your question. Success criteria: (1) a stated question and at least two related, focused questions generated during the reading; (2) evidence drawn from at least three informational texts, each credibility-assessed in a sentence, with one accuracy check where two sources were compared; (3) at least one quotation and at least two paraphrases, each with an in-text citation in MLA form or the class's assigned format, and no passage that fails the cover-and-rewrite test; (4) analysis following each piece of evidence and a closing reflection on what changed in your understanding; (5) a works-cited list in the assigned format. Alongside the long piece, complete four shorter time-frame pieces in single sittings: a ten-minute source evaluation, a one-paragraph summary of one reading for a partner, a paragraph of analysis on one piece of evidence, and a two-sentence end-of-session reflection. Submit the source log, the short pieces and the final project together; a partner checks one paraphrase against its source.
