Pre assessment IED (Design Process, Concept Sketch, Isometric)

What is the first step in the PLTW Engineering Design Process?

• Generate Concepts

• Define the Problem

• Develop a Solution

• Construct and Test Prototype

In which step of the PLTW Engineering Design Process is a prototype created?

• Evaluate Solution

• Generate Concepts

• Construct and Test

• Present Solution

The Engineering Design Process is linear, meaning that each step is only completed once and there is no going back to a previous step.

• True

• False

Which step in the PLTW Engineering Design Process involves reviewing the test results and identifying areas of improvement?

• Present Solution

• Evaluate Solution

• Generate Concepts

• Construct and Test Prototype

You’re working on a popsicle stick bridge and the prototype failed its first test due to weak structural support. Which step should you revisit to improve the design?

• Develop a Solution

• Evaluate Solution

• Generate Concepts

• Define the Problem

What is the main purpose of a concept sketch in the engineering design process?

• To create a final blueprint

• To develop a 3D model

• To communicate initial ideas visually

• To calculate precise measurements

Concept sketches should be made perfect.

• True

• False

Concept sketches can be used to illustrate multiple design ideas for the same problem.

• True

• False

Which of the following best describes how concept sketches help during team collaboration?

• They allow everyone to see the exact measurements and specifications.

• They provide a common visual reference for brainstorming and discussion.

• They eliminate the need for any further drawing or prototyping.

• They only benefit the person who created the sketch.

Concept sketches are only used at the beginning of a project and are never revised.

• True

• False
