http://www.youtube.com/watch?v=mrDxz2oRCmk How will you design your sea perch so that it is able to
solve these problems? You can use the video clips you just saw to give you some ideas of problems your Perch could be interacting with.
Please work in your SeaPerch group to write an essay on the topic (one per person)
The paper should be a minimum of one page in length. You should spend some time discussing your ideas before you begin
writing.

A Gathering StormWith 1.9 million students entering college after high school graduation, fewer than 300,000 are majoring in STEM fields, and only about 167,000 are expected to be STEM college graduates by 2011.
The U.S. government, in its report “Rising Above the Gathering Storm,” determined that this lack of STEM graduates would have a direct impact on the security and competitiveness of our country.
(Source: NCS Digest of Education Statistics, Science & Engineering Indicators 2008.)
Problem StatementThe Problem of…
• An alarming gap between the increased need for qualified engineers for government-related jobs and the graduation rates for US-born citizens in STEM related degrees to take on those jobs.
Affects…• The competitiveness of the US in a global economy• Our ability to hire and retain qualified personnel
The impact of which is…
• Underperforming on strategic programs critical to our nation’s long term success
• Loss of global competitiveness in key strategic areas• Limits our ability to take on additional research programs• Decreased morale for current workforce
A successful solution will
• Improve both the efficiency and effectiveness of our outreach programs in creating awareness, driving interest and eventual pursuit of STEM careers

What Is SeaPerch?
SeaPerch is an educational toolSeaPerch is fun and hands-onSeaPerch is a curriculumSeaPerch teaches STEMSeaPerch trains teachersSeaPerch can change kids’ mindsSeaPerch can help find the next generation of naval architects, marine, ocean, and naval engineersSeaPerch Focuses on Diversity
What is a Sea Perch?
A Sea Perch is an underwater ROV (Remotely Operated Vehicle)
The Sea Perch gets it’s power from a 12 volt battery
The Sea Perch is usually controlled by 3 motors
The Sea Perch is connected to land through a tether cable
Kit Components PVC Pipe Wire Motors Film canisters Wax Switches Propellers Circuit Board Other items
Similarities between a Sea Perch and an Commercial
R.O.V Tethered Operates on the
surface or submerged to explore underwater objects
Use of thrusters so they can maneuver through the water
Controlled by humans
“Hercules” ROV at the Deepwater Horizon Site
Students learn design and engineering principles by building an underwater ROV (SeaPerch) and participating in a culminating event/Design Competition or Showcase Fun, educational, challenging Varying levels of sophistication allow broad
appeal Integrate engineering & technology into the
classroom Introduce maritime careers into the classroom
SeaPerch Program
Integrate into curriculum based upon learning outcomes
After School Programs Out-of-School (Scouts,
4H, Boys & Girls Clubs) School club (Robotics,
Science) Summer Camps
Delivery Methods
Basic Curriculum Ship and Sub Design Buoyancy Displacement Motor Movement Soldering Vectors Circuits and Switches Ergonomic Design Depth Measurement Biological Sampling Attenuation of Light
Features Hands on learning Existing/enhanced
curriculum Mentors No-Cost Teacher Training Websites Simplified & affordable
design Kit Fulfillment Introduces career
discussions Scalable for various ages
Benefits Fun, educational and
challenging Allows one project to be
used many ways Gives ALL students a
chance Low cost per student Less time for teachers to
develop materials Teachers are trained and
supported Kits and supplies support
Teacher Training key parts of the program
Teachers with no experience can become familiar with ROV and design/engineering principles
Walk out with a working SeaPerch
Teacher Training
Mentoring Engineer/Professional
in the classroom Share career
experiences Assist teacher with
the build Assist students with
troubleshooting Wiring/Soldering
Days Reinforce concepts

Culminating Event Takes what they learn
to the next level Encourages team
spirit Fosters an end-goal Rewards creativity Rewards
sportsmanship, spirit and presentation skills
