Graider for science is the AI red pen for high school teachers who still collect paper from biology, chemistry, physics, and earth science. Graider science grading starts with the test or lab sheet you already wrote and the answer key or rubric you already use.
You upload that test and your answer key or rubric. You photograph the student papers. Marks land against your own key. You review the stack, toggle the feedback students will see, and keep the pen. Then you hand the work back as a PDF or an email.

Your key. Their lab pages. You review every mark. You keep the pen.
High school science teachers grade on paper. Biology teachers mark a cell quiz and a short lab. Chemistry teachers mark stoichiometry beside a written explanation. Physics teachers mark a problem that shows the formula, the substitution, and the unit. Earth science teachers mark a rock quiz and a brief write-up from a lab station.
Students write the pages, and you collect them. The answer key and the rubric already live in your folder. Graider science grading applies those documents to the photographs: the vocabulary you accept, the points for each written answer, and what a conclusion must include.
Upload the test and your answer key or rubric. Photograph the student papers. Get marks against your own rubric. Then review, toggle feedback, and hand the set back as a PDF or an email.
The points and the marking notes you wrote are the source of truth. Photograph every page, with even light and the full sheet in the frame, including the back and any extra sheet. Graider matches pages to students on your roster, and you confirm that match before a student sees a score.
A selected answer wants the choice you accept. A lab section wants the criteria you wrote. Answer key grading vs rubric is the short guide for which document should drive each mark.
Many science tests open with selected response: the organelle, the bond type, the formula, the layer of the atmosphere. Your key lists the accepted choice and the points. When you accept more than one option, or a written word in place of a letter, write both and the points each one earns.
Short answers sit on the same page: a definition, the independent variable, a law in one sentence. Put the full-credit response, the equivalents you count, and the partial-credit versions on the key. A response that matches a line you wrote earns those points. A response with no matching line is one you read when you review.
Chemistry and physics papers ask students to show the work: a stoichiometry item, a speed calculation, a half-life problem. You already know which lines earn points: the setup, the substitution, the numeric result, the unit, and significant figures when you score them.
Write those rows on the answer key. A correct method with an arithmetic slip can keep the method marks and lose the accuracy mark, when that is your rule. A missing unit can cost the final point. State how many significant figures you expect, and what a final number with no working earns.
AI math grading walks through partial credit and working shown on paper. On a science test, those rows still come from your key. Open hard-to-read work at review, and change the score when you disagree with the first pass.
Science papers ask students to draw and label: a cell, a circuit, a rock cycle, a force diagram. Your key or rubric says which labels are required, what each label is worth, and whether the drawing earns points separate from the words.
Open every diagram at review and set that score yourself. Diagrams, graphs, and drawings are yours to judge. You keep the pen on that call.
A lab write-up asks for the sections you assigned: a hypothesis, a method, and a conclusion, sometimes with a purpose or a short list of materials. Graider marks that write-up against the rubric criteria you upload, including the points and what a response has to include to earn them.
For the hypothesis, say whether students must name the variables and state a predicted direction. For the method, say how much detail you require. For the conclusion, say what counts as an answer to the lab question. Put partial credit on that same rubric.
You still read the write-ups you want to stand behind. Toggle a comment on when it should travel with the paper, and leave it off when the class will talk through that criterion together.
Keeping the pen means students receive feedback you released. Open pages that are hard to read, scores between two point values, and any paper you want to see yourself. Override a mark when your judgment disagrees.
Turn a comment on when it should go home with the paper. Leave it off when the class will correct that item together. Edit a note so it sounds like the margin comment you would have written. The score a student sees is the one you kept.
After you review, hand each paper back as a PDF or an email. One PDF per student holds the pages they wrote, the score you kept, and the comments you turned on. Email that file, or return it through the path your school already uses. You choose when the set goes out.
The marks come from your key and from the review you just finished. You keep the pen.

Yes. Put the points for the setup, the numeric result, the unit, and the significant figures on your answer key, including the partial credit you already give. Graider marks the photographed papers against that key. You can change any score before a paper goes home.
Write the labels you require and the points for each one on your key or rubric. Open every diagram at review, set the score yourself, and keep the mark you would explain.
Upload the rubric criteria you already use for the hypothesis, the method, and the conclusion, with the points for each. Graider marks the write-up against those criteria. You review and toggle feedback before students see it.
