Changing the pendulum design after the first trial was an example of _____________ to solve the problem presented by the teacher
Luden [163]

Answer:

Changing the pendulum design after the first trial was an example of <u>evaluating the model</u> to solve the problem presented by the teacher.

Explanation:
