Explaining a common student misconception and how to correct it

The prompt
Students consistently show this misconception when learning topic: misconception_description
Help me understand and address it properly.
1. Explain WHY this misconception is so common, what's the intuitive but incorrect mental model students are bringing, and why does it feel right to them even though it's wrong (misconceptions are rarely random, they usually come from an overgeneralization of something true in a different context).
2. Identify the specific moment in typical instruction where this misconception either gets planted or fails to get corrected (sometimes it's actually reinforced accidentally by an oversimplified early explanation).
3. Design a specific demonstration, question, or example that would create productive cognitive conflict, something that makes the misconception visibly fail in a way the student can observe themselves, rather than just being told they're wrong.
4. Give me the precise correct mental model to replace it with, stated simply enough to actually stick, not just technically accurate but unmemorable.
5. Suggest one diagnostic question I could ask early in a unit to check whether a student already holds this misconception, before it causes downstream errors.

Example output
Misconception addressed: students believe heavier objects fall faster than lighter ones. Why it's intuitive: it's an overgeneralization from real experience with air resistance (a feather does fall slower than a rock, in air), students correctly observe this but incorrectly attribute it to mass rather than air resistance, since the two are confounded in ordinary experience. Where it gets planted: often unintentionally reinforced when early instruction uses a feather-vs-rock example without immediately naming air resistance as the actual variable. Productive conflict demonstration: drop two objects of very different mass but similar shape/surface area (e.g. two same-sized balls of different density) side by side, students observe they land simultaneously, directly contradicting the mass-based prediction while controlling for the air-resistance confound. Correct mental model to install: 'gravity accelerates everything the same, air resistance is what usually gets in the way and that's about shape, not weight.' Diagnostic question suggested: 'if you dropped a bowling ball and a golf ball from the same height in a vacuum, which lands first?' reveals the misconception cleanly before air resistance can confound the answer.
