18. The teacher of an engineering class is having students work on a project in which they build a model bridge using hot glue and craft sticks. The project is being used as an assessment for the objective, 'Given basic materials, students will build a 24-inch model bridge that supports a minimum of 10 pounds.'
Answer: C
Students will design a solution to a real-world problem.
The objective requires students to create a model bridge, which directly aligns with designing a solution to a tangible engineering problem. This hands-on project encourages students to apply engineering principles to address real-world challenges.
A) Use research to investigate possible solutions.
While researching possible solutions is an important step in the engineering design process, the primary focus of this project is to have students engage in the design of a bridge rather than merely investigating options. Research would support the project but does not fulfill the core objective of designing a solution.
B) Use design software to plan real-world solutions.
Using design software can be beneficial for planning, but the emphasis of this project is on the physical construction of a bridge model. The objective specifically states the need for students to build a bridge, which cannot be achieved solely through software planning.
C) Design a solution to a real-world problem.
This option is the most accurate representation of the project’s goal. Students are tasked with creating a model bridge, which is a direct application of design principles to solve a practical engineering problem, thereby fulfilling the assessment's objective.
D) Test and compare designs with different materials.
Testing and comparing designs is an important aspect of engineering, but this option does not reflect the primary objective of designing a bridge. The assessment focuses on the construction and design rather than the comparative testing of different materials, which is a subsequent step in the engineering process.
Conclusion
The correct answer, C, encapsulates the essence of the project by emphasizing the design aspect that students must engage in to build a functional bridge model. Other options, while related to the engineering process, do not directly address the requirement for students to create a solution that meets the specified criteria of the assessment.
