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
- Predict first: if you rinse a greasy plate with plain water, where does the grease go?
- Each soap molecule has a tail that loves grease and a head that loves water. Why would needing both ends make it such a good cleaner?
- We washed grease off with soap. What is a mess that plain water can wash away all by itself?
