Imagine you want to create a kite that is lighter and more aerodynamic and want to use the design process to create your product. What would be the first thing you would do?

Research and explore what other designers have used to create kites in the past and what materials or techniques you might use for your version.

Imagine you are using the design process to create a new kind of kite. You are using the design process and have just finished making a detailed plan for how you are going to make your kite. What should you do next?

Start building! Create a quick version of your idea.

Imagine you are using the design process to design and build a new bike, which next step would you take after you had created a first prototype?

Test out your prototype to see how you might improve it in the next version.

Which of the following statements is TRUE about the design process?

The design process is a cyclical, multistep process.

What is the function of the extruder in a 3D printer?

The extruder is powered by a motor that guides the material out at the correct rate.

Which of the following statements about the extruder in a 3D printer is TRUE?

The extruder is powered by a motor that guides the material out at the correct rate.

In a 3D printer, _____________ is a heated nozzle that melts the material and places it on the correct spot.

The hot end

What is the function of the hot end in a 3D printer?

The hot end melts the material and places it on the correct spot.

Imagine you are designing a new backpack. Which of the following statement(s) about why you might choose different materials for different parts of the design is FALSE?

This is not a good idea, you should always make the design out of only one material.

In a 3D printer,_____________ is powered by a motor that guides the material out at the correct rate.

the extruder

Which of the following steps is NOT part of the Design Process?

None of the above

Imagine you are using the design process to create a new kind of kite. You've researched and explored what other kite designers have done in the past and determined which materials you will use. What should you do next?

Create a detailed plan about how you will create you kite.

Which of the following statements about the hot end in a 3D printer is TRUE?

The hot end melts the material and places it on the correct spot.

Imagine you are designing an object that needs to be very flexible. Which of the following 3D printing materials would be a good choice?

Acrylic

The cyclical, multistep process by which designers and engineers design, build, and test a new product is called:

Design process

Which of the following statements is FALSE about the design process?

Designers and engineers only go through the design process once when designing a product.

When making a new product, why might designers and engineers go through the design process more than once?

Designers and engineers repeat the design process to address different parts of their design, or improve their design further.

Imagine you are designing a new backpack. Which of the following statement(s) about why you might choose different materials for different parts of the design is TRUE?

Different materials are best suited to different tasks and it is important to test materials to know what will work best in the final design

Imagine you are designing a new backpack: why might you choose different materials for different parts of the backpack design?

Different materials are best suited to different tasks.

Imagine you are using the design process to design and build a new bike, which next step would you take after you identified the problem you were trying to solve with your new design?

Explore different materials and approaches you might take to solving the problem.

After identifying a problem you want to solve, what are the additional steps of the Design Process?

Explore, Design, Build, Test, Improve

The process by which engineers and designers quickly make a version of a product to assess a specific design element is called:

Rapid prototyping

What is a rapid prototyping?

Rapid prototyping is the process by which engineers and designers quickly make a version of a product to assess a specific design element.

Which of the following statements about rapid prototyping is TRUE?

Rapid prototyping is the process by which engineers and designers quickly make a version of a product to assess a specific design element.
