What to do

  1. Understand. Read the challenge. Circle the important need, rule, or safety limit.
  2. Plan. Use the thinking spaces below before you begin making.

  4. Check. Use evidence—not guesses—to decide what worked.
  5. Improve or explain. Make one useful change or share your strongest conclusion.
