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
- Use one measuring spoon to compare equal volumes. Why would whole-bottle weight be an unfair test?
- Pour the liquids slowly in another order. Which bands appear for a while, and which boundary starts to blur?
- Place a new object's density between two liquids before predicting its trip while the bands remain separate.
