After building a paper airplane, you throw it and it immediately crashes. You realize that there is a major flaw in your design. What should be the next step?

• destroy the old airplane and start from scratch

• change the design and test it again

• use a different color paper

What is the purpose of building a prototype?

• to test the product and make sure that it is the best solution to the problem
• to make sure that the product is in compliance with government regulations
• to determine the design constraints for the product

What's a a prototype?

• An improvement of an existing technological product, system, or method of doing something.

• A new product, system, or process that has never existed before, created by study and experimentatio

• A full or small scale working model used to test a design concept by making actual observations and necessary adjustments.

• A tangible artifact produced by means of either human or mechanical work, or by biological or chemical process.

Which step of the design process includes "Brainstorming"?

• Define problem

• Generate concepts

• Build a prototype

When you build your prototype it is really important to do this...

• Rebuild it

• Test it many times

• Present it

When you draw on paper do you start with coloring or sketching it?

• sketching

• coloring

Is this a orthographic or isometric sketch?

• orthographic

• isometric

What type of drawing is the image?

• multiview sketch

• thumbnail sketch

• perspective

• isometric

What is the purpose of sketching?

• It can tell where and how the design will be used.

• Sketching can provide details of an idea and lots of information all at once.

• Sketching is appealing to people.

• Color can be added to a sketch to show texture and appearance.
