Show of hands — before you project anything
Predict first: same tablet, two glasses, only the water temperature is different. Which finishes first, and why do you think so?
- A Way more than you'd guess
- B About what you'd guess
- C Way less than you'd guess

Discussion prompts
- Predict first: same tablet, two glasses, only the water temperature is different. Which finishes first, and why do you think so?
- Predict first: you crush a tablet to powder before dropping it. What about the tablet has changed that could speed up the fizz?
- Heat and crushing both speed the fizz. What do they have in common — what single thing are both of them increasing?
Where it shows up in real life
- An antacid tablet racing to dissolve in a warm glass of water versus a cold one
- An effervescent vitamin-C tablet erupting faster when you snap it in half first
- Cold soda holding its fizz longer than warm soda once the bottle is open
