How the activity runs
The learning connection
The acid-base reaction (baking soda + vinegar) is familiar, but explaining WHY it produces CO₂ requires chemical knowledge. The dramatic visual outcome (the 'eruption') creates a memorable event that motivates students to seek the chemical explanation — reversing the typical learn-then-demonstrate sequence.
Try it with your learner
1. Build clay volcano. 2. Add baking soda inside. 3. Add red vinegar. 4. Observe eruption.
