Why Do Kids Hate Chemistry? What I Learned When My Teen Said It’s The Worst Subject Ever
Last Tuesday, I was folding clean soccer uniforms at the kitchen table while my 10th grader Lila did homework, half a bag of cheddar Goldfish spilled next to her textbook and a sticky apple juice ring ringed my coffee mug. She slammed her chemistry book shut so hard the salt shaker jumped, and said, “I swear I’m the only one who thinks chemistry is the worst subject to ever exist.”
I looked up to see her notebook page crisscrossed with crossed-out mole calculations, a big angry X scribbled over the periodic table taped to the front cover. I bit back the automatic parent line I almost said—“It’s not that bad”—because I remembered exactly how I felt sitting in her seat 20 years ago. I also barely scraped by, counted down the days until I could drop it for something easier, and still can’t tell you what a mole is off the top of my head if you ask me unexpectedly. So instead I said, “Talk me through what’s making you want to throw that book in the trash.”
She unloaded: it’s not just that it’s hard, it’s that nothing makes consistent sense. Biology is about bodies and plants, stuff you can actually see or cut open in lab. Algebra builds on what you learned the year before, step by step, so if you get last week’s lesson you can usually figure out this week’s. Chemistry is just a bunch of tiny stuff no one has ever seen, with rules that change every single week. Last month she learned all atoms want eight valence electrons, this week half the periodic table doesn’t follow that rule. Why do some compounds end with -ate and some -ite? Who even made that up? And to make it worse, she needs chemistry to get into nursing school, so she can’t just drop it like I did. She studied three hours for her last test and got a C-, and now she’s starting to think she’s just bad at science, that maybe nursing isn’t even for her.
I asked her to show me the problem she was stuck on right then. It was balancing chemical equations, and every time she adjusted a coefficient on one side, she lost track of how many atoms were on the other. She was counting in her head and scribbling rough notes in the margin, so everything turned into a mess before she even got close to an answer. I remembered the little trick her chemistry teacher mentioned at back-to-school night, that most kids skip because it feels like extra work: draw a quick three-column table, one for element, one for reactants, one for products, and write the count down every time you change a number. We tried it on her first problem, and two minutes later she had it right. She stared at the page for a second and said, “Why didn’t the teacher just tell us to do that?” Well, she did, but it gets lost in the 10 pages of lecture notes kids copy down between passing notes and checking the clock.
That small win got me thinking. Over the last month of helping Lila with chemistry homework, I’ve talked to four other parents at car pickup who say their kid says the exact same thing: chemistry is the worst subject to ever exist. It’s not that these kids are bad at science. Most of them got A’s and B’s in biology the year before. The difference is, chemistry is the first time most teens have to learn a whole new way of thinking that they’ve never had to practice before. Everything before high school chemistry is concrete. Chemistry is all abstract, full of exceptions that don’t fit the first simple rules you learn, and it feels random if no one helps you organize that information.
Over the last few weeks, we’ve tried a few small, low-effort changes that have made a big difference. First, we spend 10 minutes every Sunday making a one-page cheat sheet for the week’s lessons. We just write down the 5 main rules, and write every exception right next to the rule in red pen. No fancy outlining or extra studying, just 10 minutes of organizing what she already learned, so she doesn’t have to flip through 20 pages of messy notes when she’s stuck on homework. Second, instead of insisting she only use the textbook or her class notes if she’s confused, I let her look up 5-minute explanations from chemistry creators on YouTube or TikTok. One of her favorites uses pizza to explain moles, which is silly, but it stuck with her way better than the textbook paragraph. Third, we add one short line to the top of that weekly cheat sheet that connects the week’s work to her goal of being a nurse. Last month it was “this helps me understand how IV fluids balance in the body.” This month it’s “chemistry explains how different antibiotics interact with cells.” It’s a tiny reminder that takes 10 seconds to write, but it cuts through that constant “why do I even need this” frustration.
It’s not like Lila loves chemistry now. Last night she complained for 20 minutes about her lab report, and she still says it’s the worst part of her school week. I still think chemistry is overcomplicated for most kids, honestly. But she got a B+ on her last test, and she didn’t cry after homework this week. She stopped saying she’s bad at science, and started saying chemistry is just annoying. That’s enough for right now. I don’t think every kid has to love every subject they take. Most of the time, when your kid says a subject is the worst ever, they’re not just being dramatic. They’re stuck on something small that no one has pointed out to them yet. It doesn’t take a fancy tutor or hours of extra study to fix it, most of the time. Just a small trick, a different explanation, and a minute to listen to why it’s frustrating. That’s all we’ve done, and it’s working, as far as it needs to. We still have half a semester left, so we’ll see how it goes.
