What’s the Problem?: Pepper Water

Posted on

Act 1: Observations and Hook

Water, pepper, dish soap.

Act 2: Questions, Possibilities, Resources

  • What happened?
  • How does the pepper behave differently at the start, at the end?
  • Why does it swirl around?
  • Where does pepper come from?
  • Does it work with something other than pepper? other than water? other than dish soap?
  • What is soap? What is it designed to do?
  • What does “clean” mean?

Act 3: Resolution and Continuation

  • Here‘s a pretty good explanation of how it works.
  • Would it work again/faster/better if soap was added a second time?
  • What if soap was added in two places at the same time?
  • How’s the pepper/water experiment similar to this? Are they related?
