• Index cards or half-sheets of paper
• Timer/stopwatch visible to students
• Writing prompt displayed on board/screen
• Collection box or designated area for papers
• Clipboard for teacher notes during review

Create 1-2 focused prompts that target the main learning objective of your lesson on properties of matter. Prepare a simple rubric or sorting method to quickly assess responses after class.

1. Five minutes before the end of your lesson on physical properties of matter, introduce the One-Minute Paper activity.
2. Explain that students will write continuously for exactly one minute in response to a specific question.
3. Display the prompt: 'What is the difference between physical and chemical properties of matter? Give one example of each.'
4. Distribute index cards and set expectations:
5. Write your name on the back of the card
6. Write continuously for the full minute
7. Focus on communicating your understanding, not on perfect grammar
8. If you get stuck, write 'I'm thinking' until your next idea comes
5. Set the timer for exactly one minute, visible to all students. Say 'Begin' clearly.
6. During the minute, circulate and observe but don't interrupt student thinking.
7. When time is up, say 'Pencils down' and collect the papers.
8. Optional extension: If time allows, select 2-3 strong examples to share anonymously with the class.
9. After class: Review the papers, sorting into categories based on understanding. Identify concepts that need reteaching or reinforcement in the next lesson.

For younger students or those with writing difficulties, allow drawing with labels instead of full sentences. For English learners, provide sentence frames. For advanced students, use a more complex prompt that requires synthesis of multiple concepts.

Quickly evaluate responses for basic understanding of the difference between physical and chemical properties. Note patterns in student responses to guide next steps in instruction. Follow up with individual students who show significant misconceptions.
