What step of the engineering design process involves gathering information to develop ideas?
Research
What is the difference between criteria and constraints?
Criteria - requirements
Constraints - limitations
An engineer is designing a model bridge. The scale of the model is:
1 inch on the model = 4 feet on the real bridge
The model bridge is 9 inches long.
How long will the real bridge be?
36 feet
What is the Engineering Design Process?
The set of steps engineers follow when creating solutions to solve a problem
Describe what happens during the design step
Taking ideas from research and making a drawing
A group of students is designing a bridge made of only paper and tape. The bridge must hold at least 10 toy cars. What is the constraint of this design?
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.
Lily is designing a miniature garden. She has a garden plan where 1 inch on the plan represents 2 feet in the real garden. If the flower bed on the plan is 3 inches long, how long is the flower bed in the real garden?
6 feet
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
Michael is working on a design for a new apartment building. After making several design drawings and choosing the best design, Michael began making a miniature toy model of the building. What step of the engineering design process is Michael at?
Prototype
Name one criteria of designing a yellow scooter
Must be yellow; Must have two wheels; Must have handlebars; Needs to be safe
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?
14 feet
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
