This resource is a part of the SeaPerch build lesson series.
Grade Level: 7th – 12th grade
Length of Lesson: 1-2 periods for modification, 2 periods for business letter
Goals:
After completing the building of a submersible SeaPerch ROV, students will use their experience and ingenuity to create a beneficial modification through the standard design process. The project will culminate in a persuasive business letter that will motivate local merchants, corporations and others to support this design project to its completion as a prototype.
- Brainstorm ideas for various modifications.
- Identify and choose a “dream” modification (modification of choice) with stated objective in mind.
- Design and draw to scale a prototype of SeaPerch plus its modification to present to other students. Classmates will provide feedback to modification plan using a rubric.
- Web search for availability of appropriate parts and equipment needed, including cost.
- Incorporate ideas, design, costs, materials and equipment needed etc. into a formal business letter to look for project funding.
- Begin to think like the various marine engineers and scientists who make their careers through the use of ROVs like the SeaPerch.
National Science Standards:
- ETS1.A: Defining and Delimiting an Engineering Problem
- ETS1.B: Developing Possible Solutions
- ETS1.C: Optimizing the Design Solution
Materials:
- SeaPerch kits (conventional design)
- Lined and graph paper
- Various PVC parts
- Collection of extra materials from the classroom and student contributions
Background:
Imagine the following scenario: A company that constructs ROVs is looking for an underwater vehicle for the next field testing season. The company does not have a very large budget, and cannot afford to build a new ROV for this project. The company needs an engineer to alter the design of their existing SeaPerch ROV so it can be used in the upcoming field season.
