Banning junk food in schools: a discussion lesson your Korean middle schoolers already have opinions about

This one lands because your students buy the stuff between classes. Seoul announced stricter cafeteria nutrition rules in late 2023, and several districts are piloting vending machine bans. The kids notice. Some bring candy from home now. Others say the school lunches got worse.

Run this with middle schoolers at high-beginner to low-intermediate. They have the vocabulary for "healthy", "expensive", "fair", and "freedom." You are teaching them to build an argument in three sentences instead of one, and to answer the other side instead of ignoring it.

What you need

Print the handout or write the central question large on the board: Should schools be allowed to ban junk food? You need two corners of the room marked YES and NO, and about ten minutes of setup before the argument starts.

The warm-up (10 minutes)

Put students in pairs. Give them two minutes to list five foods they can buy at school right now — in or near the building. Then two minutes to mark each one "healthy" or "junk." They will disagree on some. Let them.

Pull the whole class back. Ask three pairs to share one item from their list and say why they marked it that way. You will hear "ramen is junk but I eat it every day" and "chocolate milk has calcium so it's healthy." Write the contentious ones on the board. Do not correct them yet.

Now introduce the question. Tell them they are going to argue whether schools should be allowed to ban junk food completely — no sales, no vending machines, and in some versions, no bringing it from home.

The argument sorting (15 minutes)

Divide the class in half. One side prepares the YES case, the other prepares NO. It does not matter what they personally believe.

Give each side this structure to fill in, written on the board:

Each group has seven minutes to agree on their two reasons and write them as complete sentences. Walk between groups. Push them to be specific. "It's unhealthy" is not a reason; "students who eat too much sugar can't focus in fifth period" is.

After seven minutes, each side sends one speaker to the front. YES speaks first, 90 seconds. NO replies, 90 seconds. If your class can handle it, allow one rebuttal from each side (30 seconds). Time them visibly.

The flip (10 minutes)

Here is the part that makes it work: students now switch sides and argue the opposite position. The YES group becomes NO. You are teaching them that a good argument requires understanding the other side, and that being able to argue both means you actually thought instead of just picking a team.

Give them five minutes to prepare their new case. They often do it faster the second time because they have heard the opposing reasons and can counter them directly.

Run the debate again with different speakers if you have time, or as a written exit task: "Write three sentences explaining the opposite of what you just argued."

The actual law

Tell them briefly what is happening in Seoul and other districts. Schools can restrict what is sold on campus, and some have removed vending machines entirely. Students cannot be stopped from bringing food from home, but teachers can enforce no-eating-in-class rules that amount to the same thing. The debate is real, which is why they have opinions already.

Why this works now

Korean parents are arguing about this in school forums and the kids are hearing it at home. Childhood obesity rates are up, the government is pushing nutrition policy, and the schools are caught between parent complaints and public health directives. A discussion question that connects to something changing this year will always run better than one pulled from a textbook written in 2015.

Your students will argue. Let them. The point of the lesson is not to agree, it is to dispute something in English for ten minutes without falling back into Korean.
