In short: This page contains 28 copy-paste ready prompts, organized into 5 categories with a description and pro tip for each. The first 5 prompts are free instantly, no signup needed. Hand-curated and tested by the AI Academy team.
Fun & Low-Stakes (Great Icebreakers)
6 promptsCereal Is Soup
1/28✨ What it does
This prompt opens a debate on whether cereal is a type of soup. Pick the side you actually believe, then argue it, or ask the chat to switch so you can practice both.
Resolved: Cereal is a type of soup.
Pro tip: Use this as a first-day icebreaker to teach definition battles — whoever controls the definition of "soup" wins, which is the core skill of real debate in miniature.
Summer Beats Winter
2/28✨ What it does
This prompt starts a debate on whether summer is a better season than winter. Bring your own lived evidence, then push back on the weakest claim.
Resolved: Summer is a better season than winter.
Pro tip: Force speakers to use one piece of evidence that is NOT from their own life — it pushes them from preference toward argument.
The Five-Second Rule
3/28✨ What it does
This prompt debates whether the five-second rule for dropped food is legitimate. Defend the kitchen habit or the microbiology, then decide if you would still eat the snack.
Resolved: The five-second rule for dropped food is legitimate.
Pro tip: Assign the negative to your science-inclined students and watch the affirmative learn that "everyone does it" is not a warrant.
Superpower Draft: Flight vs Invisibility
4/28✨ What it does
This prompt debates whether flight is a better superpower than invisibility. Describe what you would actually do with each power, then keep the one you would choose.
Resolved: Flight is a better superpower than invisibility.
Pro tip: Push speakers past the first thirty seconds of obvious points — the round is won on second-order uses (commuting, rescue, privacy, crime) that the other side hasn't mapped.
Hot Dogs Are Sandwiches
5/28✨ What it does
This prompt debates whether a hot dog is a sandwich. Stand on the structural case or the cultural one, then try the argument on someone at the table.
Resolved: A hot dog is a sandwich.
Pro tip: Run this back-to-back with the cereal-soup motion and have students name the shared pattern — both rounds turn entirely on who sets the definition.
Homework for Teachers
6/28✨ What it does
This prompt debates whether teachers should do the homework they assign every night before assigning it. Note the one argument that would change a school policy, then reuse it in class.
Resolved: Teachers should have to do the homework they assign, every night, before assigning it.
Pro tip: A great icebreaker before a serious homework debate — students rehearse workload arguments in a frame that feels like a joke but builds real material.

School & Education
6 promptsReplace Homework with Projects
7/28✨ What it does
This prompt debates whether homework should be replaced by project-based assessment. Weigh the homework research against short practice, then name one change for a single class.
Resolved: Homework should be replaced by project-based assessment.
Pro tip: Make both sides define what counts as "homework" in their first speech — most rounds are lost because a team attacks worksheets while defending reading, or vice versa.
Ban Phones for the Whole School Day
8/28✨ What it does
This prompt debates whether schools should ban smartphones for the entire school day, including lunch and breaks. Write the phone rule you would actually vote for, then test it against a parent's reachability worry.
Resolved: Schools should ban smartphones for the entire school day, including lunch and breaks.
Pro tip: The whole round hinges on "including lunch and breaks" — coach students to fight on that ground instead of re-running the classroom-distraction debate everyone already agrees on.
Grades Before Ninth Grade
9/28✨ What it does
This prompt debates whether letter grades should be abolished before ninth grade. Say what feedback you would keep for younger kids, then try that rule on one assignment.
Resolved: Letter grades should be abolished before ninth grade.
Pro tip: Require the affirmative to name their replacement system in the first speech — abolition cases collapse under "compared to what?" if they wait until rebuttal to answer it.
Mandatory Class Participation Grades
10/28✨ What it does
This prompt debates whether class participation should not be graded. Choose the grading rule you would live with, then apply it to a quiet student you know.
Resolved: Class participation should not be graded.
Pro tip: Have students argue the side that matches the opposite of their own personality — the quiet student defending participation grades produces the most surprising speeches.
Start School at 10 AM
11/28✨ What it does
This prompt debates whether the secondary school day should start no earlier than 10 AM. Name the start time you would actually schedule, then check it against sports and parent work.
Resolved: The secondary school day should start no earlier than 10 AM.
Pro tip: Coach the negative away from denying the sleep research (a losing fight) and toward implementation costs — conceding the science while winning on feasibility is a sophisticated move worth teaching.
Pay Students for Good Grades
12/28✨ What it does
This prompt debates whether schools should pay students cash for academic achievement. Ask yourself if you would take the cash as a student, then follow what happens when the money stops.
Resolved: Schools should pay students cash for academic achievement.
Pro tip: Point both teams at the motivation research — there are real studies on both sides, so this is a strong round for teaching evidence quality over evidence quantity.
Technology & AI
6 promptsAI in Student Writing
13/28✨ What it does
This prompt debates whether students should be allowed to use AI tools on take-home writing assignments, with disclosure. Write the disclosure rule you would enforce, then try it on one take-home essay.
Resolved: Students should be allowed to use AI tools on take-home writing assignments, with disclosure.
Pro tip: Keep the round on "with disclosure" — the affirmative should defend the policy's actual mechanism, and the negative should attack whether disclosure is enforceable, not whether AI exists.
Algorithmic Feeds for Minors
14/28✨ What it does
This prompt debates whether social media platforms should be required to offer minors a chronological, non-algorithmic feed by default. Set the default you would want for a teen, then compare it to a chronological feed.
Resolved: Social media platforms should be required to offer minors a chronological, non-algorithmic feed by default.
Pro tip: Teach the difference between banning and defaulting here — the motion is deliberately moderate, and teams that debate it as a ban argue past each other.
Self-Driving Cars and the Human Driver
15/28✨ What it does
This prompt debates whether human driving should be restricted on public roads once autonomous vehicles are statistically safer. Name the driving rule you would accept, then ask who pays when the machine is at fault.
Resolved: Once autonomous vehicles are statistically safer than human drivers, human driving should be restricted on public roads.
Pro tip: Grant the affirmative its premise (the motion already stipulates "statistically safer") and coach the negative to fight on values and transition costs instead of disputing the hypothetical.
The Right to Disconnect
16/28✨ What it does
This prompt debates whether employees should have a legal right to ignore work messages outside working hours. Say whether you would ignore tonight's work messages, then try that boundary once.
Resolved: Employees should have a legal right to ignore work messages outside working hours.
Pro tip: Have students research France's actual right-to-disconnect law — real-world implementation detail elevates this from opinion swap to policy debate.
Facial Recognition in Schools
17/28✨ What it does
This prompt debates whether schools should not use facial recognition technology on their campuses. Write the campus camera rule you would want, then check it against a real safety case.
Resolved: Schools should not use facial recognition technology on their campuses.
Pro tip: Push both sides to specify use cases — attendance, building access, threat detection — because the motion is winnable or losable depending on which application the room ends up picturing.
Video Games Are a Sport
18/28✨ What it does
This prompt debates whether esports should count as a school sport with equal funding and varsity status. Say how you would split the sports budget, then defend that split to a coach.
Resolved: Esports should count as a school sport with equal funding and varsity status.
Pro tip: A high-energy motion for gamer-heavy classes — assign the negative to the gamers and the affirmative to the athletes for the best rounds.

Society & Ethics
5 promptsWhite Lies
19/28✨ What it does
This prompt debates whether it is sometimes morally right to lie. Draw your own line on lying, then test it on a surprise party and a serious harm.
Resolved: It is sometimes morally right to lie.
Pro tip: Introduce Kant's murderer-at-the-door case and let students fight it out — it's the classic stress test and gives the round philosophical spine without needing prior reading.
Zoos in 2026
20/28✨ What it does
This prompt debates whether zoos do more good than harm. Say whether you would still buy a zoo ticket, then defend that choice out loud to someone who disagrees.
Resolved: Zoos do more good than harm.
Pro tip: Coach teams to weigh, not list — the round is won by the side that explains why its kind of good (species survival vs individual animal welfare) should count for more.
Billionaire Philanthropy
21/28✨ What it does
This prompt debates whether society benefits when billionaires fund public goods through private philanthropy. Pick the funding model you would defend, then name who should choose which problems matter.
Resolved: Society benefits when billionaires fund public goods through private philanthropy.
Pro tip: Steer students toward "compared to what?" — the affirmative's strongest ground is that the realistic alternative is not better taxation but nothing, and the negative must contest exactly that.
Voting at Sixteen
22/28✨ What it does
This prompt debates whether the voting age should be lowered to sixteen. Draw the voting-age line you would keep, then test it against work, taxes, and brain science.
Resolved: The voting age should be lowered to sixteen.
Pro tip: This is the rare political motion that splits on age rather than party — ideal for classrooms because students argue genuinely held positions without partisan landmines.
The Ethics of Buying Cheap
23/28✨ What it does
This prompt debates whether consumers are morally responsible for the labor conditions behind the products they buy. Change one purchase on your next shop, or argue why the company still owns the blame.
Resolved: Consumers are morally responsible for the labor conditions behind the products they buy.
Pro tip: Ban the word "should" from the first minute of each speech — it forces students to establish what moral responsibility even means before claiming who carries it.
Quickfire One-Minute Debates
5 promptsBooks vs Movies
24/28✨ What it does
This prompt debates whether the book is always better than the movie. Name one adaptation that beats the book, or hold the always and watch it break.
Resolved: The book is always better than the movie.
Pro tip: Run it in sixty seconds per side precisely because of the word "always" — quick rounds teach students to spot and exploit absolute language instantly.
Breakfast Supremacy
25/28✨ What it does
This prompt debates whether breakfast is the most important meal of the day. Choose whether breakfast still earns a plate tomorrow, then ask where the most-important claim came from.
Resolved: Breakfast is the most important meal of the day.
Pro tip: Use this to teach "challenge the premise" — the strongest negative move is asking what "important" even measures, modeling how to fight a motion's frame rather than its content.
Pineapple on Pizza
26/28✨ What it does
This prompt debates whether pineapple belongs on pizza. Map the taste disagreement instead of winning it, then order the pizza you actually want.
Resolved: Pineapple belongs on pizza.
Pro tip: After the round, ask the class what evidence could even settle it — the debrief teaches the difference between matters of fact and matters of taste better than any lecture.
Calling vs Texting
27/28✨ What it does
This prompt debates whether a phone call is better than a text. Choose how you will reach them today, then notice whose time that choice seizes.
Resolved: A phone call is better than a text.
Pro tip: Perfect for generational framing — have students predict their grandparents' position, then defend the opposite of their own habit.
Erase the Bad Memories
28/28✨ What it does
This prompt debates whether you should delete your most painful memory if you could. Sit with the answer you would actually pick, then ask what else would vanish with the pain.
Resolved: If you could delete your most painful memory, you should.
Pro tip: Save this for the end of a quickfire session — it starts silly-sounding and lands deep, which shows students the format can hold weight.
