AI Grammar Checker for Science Writing
Priya is writing a chemistry lab report and her teacher has told her to use passive voice in the methods section but her grammar checker keeps marking it as an error. She has also been told not to use prove or confirm in her results, but her grammar checker does not distinguish between informal language and scientifically inaccurate language. With Science as the subject, the AI Grammar Checker can follow scientific writing conventions: passive voice in methods is correct, not an error; hedging language in results is required, not a weakness; and technical precision matters more than stylistic variation.

How science teachers use it
Grammar feedback calibrated to the conventions that matter for this audience.
Passive voice in science: when it is required, not just acceptable
The methods section of a science lab report or research paper conventionally uses passive voice: the samples were heated rather than we heated the samples. The passive is required because methods should describe a procedure that anyone could replicate. A general grammar checker that flags all passive voice as an error is wrong for science writing. With Improve with AI on, name the section with your text, and an AI can check passive voice in a methods section with that in mind.
Hedging language: suggests, indicates, may, not proves
Science writing requires language that accurately represents the certainty of claims. The data proves that is almost never correct, science rarely proves with certainty, it accumulates evidence that supports or contradicts hypotheses. Correct hedging vocabulary: the results suggest, the data indicate, this finding is consistent with, the evidence supports the hypothesis that. The AI flags both under-hedging (overclaiming certainty) and over-hedging (excessive qualification).
IMRaD tense conventions: past tense for methods and results, present for discussion
Science writing uses tense strategically: past tense for describing what was done (Methods) and what was found (Results), because these refer to specific past actions and observations. Present tense in the Discussion section, because the discussion makes general claims that are still true. With Improve with AI on, an AI can point out tense errors relative to the IMRaD section you name with the text.

Questions teachers ask
Why is passive voice appropriate in science writing?
Passive voice is appropriate in science writing (specifically in methods sections) because it focuses attention on the procedure rather than the researcher who performed it. Science is meant to be replicable: the procedure does not depend on who performed it. This is why science teachers and journal editors require passive voice in methods, it is a disciplinary convention, not a stylistic preference.
What words should science students avoid in results sections?
Words to avoid in science results sections: proves (science does not prove (it produces evidence), confirms (use is consistent with or supports), shows that (use indicates or suggests), clearly demonstrates (certainty overstatement) use strongly indicates). Words to use: suggests, indicates, is consistent with, supports the hypothesis that, may indicate.
How does it handle technical vocabulary in science writing?
Technical vocabulary in science writing is not flagged as an error, it is expected and necessary. The AI Grammar Checker does not substitute technical terms with plain language. However, it does flag inconsistent use of technical terms (switching between concentration and amount to refer to the same measurement) and everyday words used where the technical term is required.
Does it check the conclusion section of a lab report?
Yes. The conclusion section of a lab report should: restate the hypothesis, summarize whether the evidence supports or contradicts it, explain the main evidence, acknowledge sources of error, and suggest directions for further research. The grammar checker checks tense and hedging language; check the completeness of the conclusion yourself.
Can it help with AP Science free-response essay grammar?
Yes. AP Science free-response questions require students to explain scientific concepts in precise scientific language. Common grammar errors in AP Science responses: failing to define technical terms before using them, using everyday language where scientific terminology is expected, overconfident claims without hedges, and passive voice in explanations where active voice would be clearer.
