Write a prompt that gets a group chat message under 60 words, plain text, explaining how the demo showed the three rock types, using only the lab's crayon steps, and ending with one question for the group. Use the corrected step from the TA, and skip the textbook's extra rock names.","materialLabel":"Your lab notes (attached to your prompt automatically)","material":"GEOL 1010 - Lab 4 - Crayon rock cycle (TA: Marcus)\n\nSTEPS WE DID:\n1. Shaved crayons into small bits = sediment.\n2. Pressed the shavings together in foil with our hands = sedimentary rock (layers you can see).\n3. Put the foil packet in warm water and pressed with a book = metamorphic rock (heat + pressure, bits squished together but NOT melted).\n4. Melted crayons completely in a cup over hot water, then let them cool = igneous rock.\n\nMy note: I wrote that step 3 was \"melting.\"\n  ** Marcus (TA): \"No! Metamorphic = heat and pressure WITHOUT melting. If it melts, it's igneous. That's the whole point of step 3 vs step 4.\" **\n\nLab question to answer in the report: \"Explain how the crayon demo models the three rock types.\"\n\nTextbook ch. 5 lists examples like granite, basalt, shale, marble, quartzite. (Marcus: \"Don't need specific rock names for this lab.\")\n\nGroup chat (Priya): \"wait so is metamorphic just melted rock?? i'm confused\"\nLab report due Friday.","rules":[{"type":"maxWords","max":60},{"type":"plainText"}],"mistakes":[{"title":"Asking the general question","why":"The AI explains the rock cycle from a textbook, with rock names and diagrams, not the lab demo.","fix":"Say: \"Use only our crayon demo steps.\"","checks":["r0"]},{"title":"Missing the TA's point","why":"Your notes include your old mistake that step 3 was melting.","fix":"Add: \"Make clear metamorphic is heat and pressure without melting.\"","checks":["r1"]},{"title":"Not saying where it's posted","why":"The AI writes a formal explanation with headings, which reads oddly in a group chat.","fix":"Add: \"A casual group chat message, ending with a question for the group.\"","checks":["r2"]},{"title":"Trusting the AI to count words","why":"AI is bad at counting.
