The Immortal Life of Henrietta Lacks is unusually well suited to teaching research skills because it sits at the intersection of multiple well documented public records: court cases, scientific publications about HeLa cells, journalistic coverage, and Skloot's own extensively cited endnotes, which give students a genuine trail of primary and secondary sources to follow beyond the book itself. A research paper assignment built around this book can teach students to move from a secondary synthesis, the book, back to the primary sources it draws on, which is a genuinely valuable research skill that many student papers never actually practice. Grading this kind of assignment well requires evaluating the research process itself, not just the final written product.

A strong version of this assignment requires students to trace at least one specific claim from the book back to its original source, using Skloot's own endnotes as a starting point, and then evaluate whether the book accurately represents what that original source actually says. This exercise teaches students that even well researched nonfiction involves interpretive choices, and it builds a healthy skepticism toward secondary sources that will serve students well in any future research they conduct. Grading should check whether students actually located and read the primary source, rather than simply asserting that the book's representation is accurate or inaccurate without doing the verification work the assignment requires.

Beyond this verification exercise, a fuller research paper can ask students to go further than the book, researching a specific dimension of the HeLa cell story that Skloot mentions briefly but does not fully explore, such as the specific scientific applications HeLa cells enabled or the legal precedents set by cases involving tissue ownership since the book's publication. This extension pushes students to treat the book as a starting point rather than an endpoint, which is the research posture the assignment is ultimately trying to build. A rubric should reward genuine extension beyond the book's content over papers that simply restate what Skloot already documented in more of the student's own words.

Teaching Source Evaluation as a Distinct Skill

Because this research inevitably surfaces sources of varying quality, from peer reviewed scientific papers to popular journalism to advocacy organization websites, the assignment offers a natural opportunity to teach explicit source evaluation criteria: authorship, publication venue, currency, and potential bias. A short source evaluation worksheet, required alongside the final paper, where students briefly justify why each source they used is credible for the specific claim it supports, makes this evaluative thinking visible and gradeable rather than assuming students did this work invisibly before writing. Papers that cite a source without any apparent awareness of its limitations or potential bias should lose credit on this dimension even if the paper's overall argument is otherwise reasonably strong.

• Require students to trace at least one specific claim back to its original primary source
• Ask for a brief source evaluation justification alongside the final paper's bibliography
• Reward genuine extension beyond the book's content over restatement of existing material
• Score citation accuracy and formatting as a distinct, smaller component of the total grade
• Flag any source used without apparent awareness of its limitations or potential bias

Building a Grading Timeline Around Research Checkpoints

Because this assignment involves a real research process rather than analysis of a single text, grading benefits from checkpoints spread across the assignment timeline rather than a single evaluation at the end, which catches research problems, like an unreliable source or a claim that cannot actually be verified, while there is still time for students to fix them. A source list checkpoint, submitted and briefly reviewed roughly a week before the paper is due, lets a teacher flag any concerning sources early rather than discovering them only after the full paper has already been written around a shaky foundation. This checkpoint does not need heavy grading weight, but it needs enough teacher attention to catch genuine problems before they compound into a weaker final paper.

A second checkpoint, a brief outline or thesis statement submitted after the source list but before full drafting begins, catches structural or argumentative problems early as well, and it gives the teacher a chance to redirect a student whose research has led them toward a claim the available sources cannot actually support. Teachers who build in these two checkpoints report that final papers require noticeably less substantive revision feedback, since the major structural and evidentiary problems have already been caught and addressed earlier in the process, which makes the final grading pass faster and more focused on refinement rather than fundamental rework.

Evaluating the Final Paper Holistically

With checkpoints already handling much of the research process evaluation, the final paper grading can focus more specifically on argument quality, writing clarity, and how well the student integrated their research into a coherent narrative rather than a disconnected list of facts pulled from various sources. A rubric weighted toward synthesis, meaning how smoothly the student weaves together material from the book, primary sources, and their own analysis, rewards papers that read as unified arguments over papers that read as a sequence of separately researched paragraphs stitched together without much connective reasoning between them. This synthesis criterion is often what most clearly separates a strong research paper from a merely competent one at this level.

Because the research process has already been checked at earlier stages, teachers grading the final paper can move somewhat more quickly than they would for a paper where research quality is being evaluated for the first time only at the end, which helps offset the additional time investment the checkpoint system requires earlier in the unit. Overall, this checkpoint based approach tends to produce both stronger final papers and a more sustainable grading workload across the full arc of a multi-week research assignment, even though it requires more total touchpoints with each student's work than a single end-of-unit submission would.
