A story to share together
Get comfortable. Make a guess together. See where the story takes you.
Everyone gets a guess. You don’t need to know the answer before you begin.
After the story: things to talk about
- Before you drop the tablets in, guess: which glass — cold or warm — will finish fizzing first? Then time them.
- The warm one finished sooner. Did it really make more bubbles, or just let them out faster?
- Now crush one tablet to powder and drop it in cold water. Why does it erupt so fast without any heat?
