If things go wrong
• If students say they do not know where raw meat goes in a refrigerator, the passage and the question text
explain the rule: foods that must be cooked go lowest.

• If a student says their family does one of the mistakes, say that is a good reason to learn the fix. Do not
argue; just move on.
• If the room gets loud, return to silent work for five minutes.
• If a student mentions feeling sick from food or something else that worries you, follow your school’s reporting
procedure and tell the office right away.
Early finishers
• Draw a refrigerator with four shelves and label what goes on each, using only words.
• Write a short rule list titled “Four habits that stop germs from spreading.”
Support and challenge
• Support: Do questions 1–3 as a group, then let students finish alone.
• Challenge: Write a new cross-contamination scenario and the fix, then trade with a neighbor.
