Read Noni's research question about the history of the airplane. What did the Wright brothers use to make their first powered airplane? Noni is trying to make her question more complex. Which is the best revision? What was the Wright brothers' first powered airplane made of? Would the Wright brothers' first powered airplane have been successful if they had chosen other materials? How did the materials the Wright brothers chose contribute to the success of their first powered airplane? What materials did the Wright brothers use to build their first powered airplane?

Would the Wright brothers' first powered airplane have been successful if they had chosen other materials?

Explanation:

Remember, Noni wants a research question that is more complex; meaning one that requires giving careful thought and explanation.

Rather than just asking what the Wright brothers used to make their first plane, asking, Would the Wright brothers' first powered airplane have been successful if they had chosen other materials? provides a measure of complexity since it requires first knowing what they use, before exploring whether they would be successful if they had chosen other materials.
