Stating "I need a way to retrieve my phone" completed which step of the process?

• defining the problem
• developing a solution
• doing research
• evaluating the solution

Which idea was chosen as the best possible solution to the problem?

During the testing stage, the small experiments are known as _____

• trials
• prototypes
• strengths
• failure points

For the trials to be really useful, what must be done with the variables?

• insulate them
• sever them
• isolate them
• detach them

Conditions that remain constant throughout the experiment are called _____
