Lessons in Chemistry Study Guide

Higher Level Comparative · 2027 & 2028 Leaving Cert

Lessons in Chemistry follows a woman the 1960s scientific establishment refuses to take seriously, and traces what she does with that refusal. For a comparative essay it is a strong source of points on institutional prejudice, an unconventional family, and grief that does not stop a life from continuing.

Bonnie Garmus published Lessons in Chemistry in 2022. It became an international bestseller and was later adapted for television. On the Leaving Cert it is studied as a comparative text, meaning you are not writing a single-text essay about it alone, you are pairing it with one or two other texts on your course under a set mode: Theme or Issue, General Vision and Viewpoint, Literary Genre, or Cultural Context. That changes how you should read it. You are not just following Elizabeth Zott’s story, you are collecting comparison points as you go.

The Story

Elizabeth Zott is a chemist working at a research institute in 1950s and early 1960s California, in a field that treats a serious female scientist as a contradiction in terms. Her intelligence and her precision are constantly underestimated or stolen by male colleagues, and the institute never gives her the standing her work deserves.

Her one real intellectual partnership is with Calvin Evans, a brilliant, socially awkward chemist at the same institute. Their relationship grows out of mutual respect rather than convention, and the novel treats their unmarried domestic life together, and the dog they share, Six-Thirty, as its own kind of family long before the surrounding society would recognise it as one.

Calvin is a competitive rower as well as a scientist, and the discipline of rowing, precise, repetitive, dependent on trusting people around you, recurs through the novel as a way of describing how he and later Elizabeth approach difficulty. His death, in a sudden accident, ends the partnership abruptly and without warning, which is part of the point: the novel refuses to give Elizabeth’s grief a tidy shape or a decent interval before life demands she keep functioning.

Pregnant and unmarried, Elizabeth is dismissed by the institute rather than supported by it. She raises her daughter, Madeline, alone, and out of financial necessity takes a job she never sought: hosting an afternoon television cooking programme. Instead of performing the light, deferential persona the format expects, she teaches cooking as applied chemistry, addressing her audience of housewives as capable adults, and the show becomes an unlikely, subversive success. Through her own daughter’s precocious intelligence and the loyalty of people who see her clearly, principally her neighbour Harriet Sloane, Elizabeth builds a version of a family and a career on her own terms. Even a former colleague at the institute, Miss Frask, who initially seems part of the machinery working against Elizabeth, turns out to have her own history of being failed by the same institutions, and becomes an ally rather than an obstacle as the novel goes on.

An Institution That Will Not Look at Her Properly

The comparative point that travels furthest from this text is institutional: a workplace that has already decided what a woman is capable of before she opens her mouth. Elizabeth’s competence is never in question inside the novel. What is in question, over and over, is whether the men around her will admit it. That gap between demonstrated ability and denied recognition is a strong Theme or Issue point, and it pairs naturally with any text where a woman’s intelligence or authority is discounted by the people meant to be judging her fairly.

A Family Built Outside the Rules

Elizabeth and Calvin’s household, and later Elizabeth and Madeline’s, never looks like the era’s approved version of a family, and the novel is not embarrassed about that. An unmarried working couple, then a single mother earning her own living and raising a startlingly self-possessed daughter, both quietly argue that a family is defined by loyalty and care rather than by a marriage certificate. This is a useful General Vision and Viewpoint point: the novel’s outlook is essentially hopeful about the ability of people to build something workable and good outside institutions that have failed them.

Chemistry as a Way of Seeing

One structural choice worth naming in a Literary Genre answer is how thoroughly the novel filters its world through Elizabeth’s scientific mind. She explains cooking in precise chemical terms on live television, refusing to soften her language for an audience assumed to want less. The device does double work: it characterises Elizabeth as someone who will not perform stupidity to make others comfortable, and it turns an ordinary domestic task, cooking dinner, into something rigorous and worth respecting, which is exactly the argument the novel is making about the women watching her. It is also a useful point of contrast if your comparative pairing includes a text told in a more conventional, linear voice: Garmus keeps returning to Elizabeth’s scientific register even in scenes of grief or humiliation, so the narrative’s tone rarely softens to match the sentiment of the moment.

Who’s Who

Elizabeth Zott is a chemist whose exacting mind and refusal to perform likeability the way her era expects make her both isolated and, eventually, influential on her own terms.

Calvin Evans is Elizabeth’s partner, a gifted and somewhat solitary chemist at the same institute, whose death partway through the novel changes its direction.

Madeline “Mad” Zott is Elizabeth and Calvin’s daughter, unusually perceptive for her age and closely attached to her mother’s way of thinking.

Harriet Sloane is Elizabeth’s neighbour and closest ally, whose friendship supports Elizabeth through single motherhood and career upheaval.

Six-Thirty is the family dog, given an unusually large presence in the narrative as an observer of the household.

Lessons in Chemistry Study Guide: Using This in the Exam

How to use it: Comparative answers reward a small number of well-developed points used consistently across both or all three texts, not a full retelling of each plot. Decide early which mode you are answering (Theme or Issue, GVV, Literary Genre or Cultural Context) and select two or three moments from Elizabeth’s story, the firing, the television show, the household with Harriet and Madeline, that speak directly to it. Name your comparison text explicitly in every paragraph rather than treating the texts separately.
