A. The bridge must hold ten (10) cars
B. The bridge should be the longest in the class
C. The students only have 10 sheets of paper and 2 feet of tape.
D. The students want their bridge to look cool
C. The students only have 10 sheets of paper and 2 feet of tape.

When developing possible solutions to a problem, engineers need to consider the criteria and constraints of their design solution.
What are criteria and constraints?
Criteria = The requirements that make it a good solution
Constraints = The limitations you are allowed to work with

An engineer is designing a scale model of a car to test its shape and design.
The scale is:
1 inch on the model = 2 feet on the real car
The model car is 7 inches long.
How long is the real car?

Describe the following steps of the Engineering Design Process:
Research
Design
Prototype
Research - gather information to develop ideas
Design - take the ideas from research and make a drawing.
Prototype - take the drawing and make a physical model
