Engineering Design Process Cardboard Bike by Izhar Gafni

In this video, we will follow the journey of an engineering, Izhar Gafni, who strives to make a bicycle out of cardboard. What is your prediction?

• It will be a failure, even after multiple attempts

• After multiple attempts, he will make a bicycle out of cardboard, but it will not be an adequate replacement for a traditional bicycle

• After multiple attempts, he will successfully build a carboard bicycle that could serve as an adequate replacement for a traditional bicycle

By deciding to build a bicycle out of cardboard, Izhar was conducting the first step of the engineering design process, which is to...

• build a prototype.

• identify the need or problem.

• consider possible solutions (brainstorm).

• choose the best solution(s).

By conducting small tests with cardboard to learn more about it and its capabilities, Izhar was conducting the second step of the engineering design process, which is to...

• test your prototype.

• build your prototype.

• choose the best solution(s).

• research the need or problem.

Having built, tested, and evaluated early prototypes, Izhar decided to design, build, and test new prototypes that better addressed his need/problem. By doing so, he was utilizing the important final step of the engineering design process, which is to...

• build a prototype.

• consider possible solutions (brainstorm).

• redesign.

• communicate your solution.

To solve a problem or address a need, certain criteria must be met, within certain constraints. According to Izhar, what was the criteria that his bicycle had to meet to be considered a viable solution to his problem/need? Select the best answer

• Made out of cardboard

• It's strong

• It's durable

• It's cheap

• All of the answers
