This is an engaging, problem-based inquiry activity that will get your students thinking deeply about chemical and physical changes. Designed for science students in the middle grades, this lesson uses something most people like - popcorn - to help distinguish between chemical and physical properties and changes.
The question of whether popping popcorn is a physical change or a chemical change is a tough one. Students will explore this question in this lesson by:
- observing popcorn pop in slow motion
- examining kernels and popped pieces of popcorn
- participating in active formative assessments
- discussing and debating
- recording information
