Question

Marty is developing a new way to heat an airplane's windshield to prevent it from accumulating ice when in flight. A thin layer of clear, conductive material is injected between two layers of thick windshield plastic. A very small electric current is run through the inner material to keep the plastic layers warm.

Answer 1

The question part that is missing is -

How might using a model help develop the design?

Answer:

The correct answer would be - it could be tested in a lab.

Step-by-step explanation:

A model is a smaller representation or test unit for an idea, or a process that is which is used to test or explain the idea or process that can not be made multiple times on a large scale.

Developing a new method to heat an airplane's windshield to prevent it from ice accumulation when in flight, testing this new idea, is very risky in the actual plane during flight so testing this method in the lab on a model would be helpful.
