Discussion questions

Discussion

  1. Why is brainstorming multiple solutions better than jumping straight to one answer?
  2. What does asking 'what if…?' help an engineer think about?
  3. Can a 'bad' idea during brainstorming ever lead to a great solution? How?
  4. What are some ways to judge which brainstormed idea is worth trying first?

Quick work-a-long

Vocabulary: brainstorm, what-if, solution, idea, generate, compare, evaluate.

Try it: Give students a challenge (e.g., 'keep an ice cube from melting for 10 minutes'). Set a timer for two minutes and generate as many what-if solutions as possible without judging any. Then vote on the top two to test.
