# Ways of Thinking: Make Connections

Take notes about classmates’ calculations and comparisons of the Strouhal numbers, and other students’ use of the problem-solving process.

As your classmates present, ask questions such as:

- What is the relationship between the variables in the problem? How did you use this relationship to help you write your formula?
- As the wing-flap frequency of a bird increases, what happens to the amplitude? Why?
- Do you think the Strouhal numbers for all birds compare in the same way that the numbers for the hummingbird and the albatross compare? Why or why not?
- Which steps of the problem-solving process were the most helpful when answering the questions?
