Why Do So Many Teens Hate Chemistry? What I Learned When My Kid Said It’s The Worst Subject Ever
The backpack hit the kitchen counter hard enough to slosh coffee over the edge of my mug last Tuesday. Lila, my 10th grader, dropped into the chair across from me, kicked the table leg, and said, “Chemistry is the worst subject to ever exist. Am I seriously the only person who hates this garbage?” A crumpled lab report peeked out of her neon binder, her after-school apple sat unpeeled on the counter, and I could see her eyes were shiny from holding back frustration in the hallway.
I’d heard her complain about tests and busywork before, but this was different. She’d liked biology last year—she’d even stayed up late three nights in a row making a diorama of cell division, for crying out loud—so this level of vitriol caught me off guard. I asked her what was wrong, and she spent 15 minutes ranting about moles that aren’t animals, Lewis structures that look like random dots, and rules that change depending on what type of reaction you’re looking at. “It’s just a bunch of random stuff someone made up that I’m supposed to memorize for no reason,” she said. “None of it connects to anything I actually care about.”
I was a part-time ed tech at the local elementary school, so I know a little about learning blocks, but I’d never seen one this sharp for a single subject. That night, I posted in our parent Facebook group just asking if anyone else’s kid said the same thing. Within an hour, I had 27 comments. Half of them were from parents saying their teen called chemistry the exact same thing. One even said her straight-A kid refused to take AP chem after honors, just because they hated it so much. So no, Lila isn’t the only one. That was the first thing I learned.
I emailed her chemistry teacher to set up a quick chat after school, to see what was going on. Mrs. Henderson, her teacher, didn’t brush it off as teen angst. She said this is the most common complaint she gets, and it’s almost never because kids are dumb or don’t try. It’s because chemistry is the first science most kids take that’s entirely abstract. Think about it: biology is about living things, you can see cells under a microscope, you know what a heart does. Physics is about stuff moving, you can throw a ball and feel gravity. But chemistry? You’re talking about things too small to see, and you’re using symbols, formulas, and math all to describe something you can’t even point to. Most kids don’t make that shift from concrete to abstract thinking automatically. She said half the kids she teaches hit this exact wall in the first semester. That was the second big insight.
I decided to sit with Lila for homework one night to see it for myself. I’d taken chem in high school, I remembered hating it too, but I’d forgotten what it felt like to be new to it. She pulled up a practice problem: “How many moles of carbon are in 2.5 moles of CO2?” She stared at it for two minutes, then said, “I don’t even remember what a mole is, really. They just say it’s a unit, but what does that even mean?” I remembered what Mrs. Henderson said about making abstract ideas concrete, so we grabbed the open bag of M&Ms on the counter. I said, “A dozen is 12 of anything, right? A dozen M&Ms, a dozen cookies. A mole is just a dozen, but for super tiny things like atoms. Because atoms are so small, you need a huge number of them to make enough to weigh or use. So a mole is 6.02 times 10 to the 23rd atoms, same as a dozen is 12.” She stared at me, then at the M&Ms, and laughed. “Why didn’t they just say that in the first place?” That’s when I realized how much of the frustration is just bad translation, not bad learning.
Mrs. Henderson gave us a few tiny, low-effort changes that made a huge difference, none of which required a tutor or extra hours of homework. First, Lila starts every chem homework session with two minutes of “translating”: every symbol or term she’s working with that day, she says out loud what it actually is, not just the textbook definition. If it’s a covalent bond, she says “that’s when two atoms share an electron, like two kids sharing a cookie” instead of just memorizing the formal phrase. Second, instead of making a huge study guide with 50 rules before every test, she writes one new rule on a 3×5 card every night, in her own words. She keeps the stack in her backpack, and flips through it for five minutes every morning on the bus. No cramming 20 rules the night before a test, which was just overwhelming her. Third, she stays after class for five minutes once a week, just to ask the one thing that confused her that week. Before, she’d just let the confusion sit, and every new concept built on the confused old one, so it just got worse and worse. Now she clears up one small mess every week instead of a huge mess before the test.
It’s not like Lila suddenly loves chemistry. She still complains about it when she pulls out her binder every night. Last week she said it’s “still the worst subject ever invented, except maybe whatever macroeconomics is, which I don’t even take yet.” Her grade went from a D+ in the first quarter to a B- this quarter, and she doesn’t cry in the car before tests anymore. She’s still not sure if she’ll take AP chem junior year, and that’s okay. She wants to study wildlife conservation, which needs a couple of science credits, but she can take environmental science instead, which she’s already said sounds way more interesting.
I used to think if my kid hated a subject this much, it meant they weren’t trying hard enough, or they weren’t cut out for science. Now I know it’s usually just that the subject is structured differently than what they’re used to, and no one took two minutes to translate the weird jargon into something that makes sense. Small, consistent tweaks do more than big pep talks or extra study sessions. Lila still thinks chemistry is the worst. Turns out, she’s got a lot of company.
