http://www.youtube.com/watch?v=sHaHw8J9Ni0 http://www.youtube.com/watch?v=mrDxz2oRCmkHow 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. Slide3
Current Situation

A Gathering Storm
With 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.

Problem Statement
The 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

SeaPerch can change kids’ mindsSeaPerch can help find the next generation of naval architects, marine, ocean, and naval engineersSeaPerch Focuses on DiversitySlide8
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 batteryThe Sea Perch is usually controlled by 3 motorsThe Sea Perch is connected to land through a tether cable Slide9
