1. ASK
What is the problem?
What are some possible solutions?
What have others done?
2. IMAGINE
What are the possibilities?
What else can be done?
What is the best solution?
3. PLAN
Is the plan possible?
Where should you start?
What materials are needed?
4. CREATE
Can a model (prototype) be made?
Have you followed the plan?
Does it meet the goal (criteria)?
5. IMPROVE
Does the prototype work?
What will make it better?
What can be done differently?
6. COMMUNICATE
Are changes needed?
What do others think?
Did you solve the problem?
