Get moon phases explained with the lamp-and-ball demo

Practice: Saying who it's for. About 5 minutes.

About this exercise

In your intro Astronomy lab, you still think moon phases come from Earth's shadow. Get exactly 3 numbered sentences using only the lamp-and-ball demo (what's always lit, why we see different amounts, what a new moon is), then one line starting 'Check:' with a question to test yourself, under 80 words, plain text. Correct the shadow idea without using the words 'eclipse' or 'umbra'.

Common mistakes when you ask AI for this

Asking the general question. The AI gives a textbook diagram explanation, not the demo you did. Try: Say: "Use only the lamp-and-ball demo from my lab."
Not saying how many sentences. The AI picks its own number, and it usually picks more sentences than you need. Try: Be exact: "Exactly 3 numbered sentences."
Not addressing the misconception. The AI may explain phases but never say the shadow idea is wrong, or bring up eclipses. Try: Add: "Say it's not Earth's shadow, without using eclipse or umbra."
No way to test yourself. The AI explains and stops, so you never check whether it stuck. Try: Add: "End with one line starting 'Check:' with a question, no answer."
Trusting the AI to count words. AI is bad at counting. Ask for a total and it often lands 20% over. Try: Cap each sentence: "each under 18 words."
Forgetting where it will be read. AI formats for a screen, with bold and headings that show up as stray symbols in your lab report. Try: Say: "Plain text, no bold, no headings."
