Seven youths from Grant and Benton counties will be representing Arkansas at the 2017 National SeaPerch Challenge at Atlanta Friday and Saturday, May 19-20.
At Georgia Institute of Technology, the competition will put the emphasis on engineering as each team puts its remotely operated underwater vehicle through its paces.
The junior team is 4H2O, representing Grant County and coached by Brad McGinley, Grant County extension staff chair for the University of Arkansas System Division of Agriculture. The senior 4-H team is Glitter Girlz Gold from Benton County, coached by Karl and Tamara Kay.
Remotely operated vehicle
Through SeaPerch, an aquatic engineering program, 4-Her’s are able to build an underwater water remotely operated vehicle, or underwater ROV, out of a kit of easily accessible parts. SeaPerch is one of the science, technology, engineering and mathematics initiatives 4-H uses to help build STEM skills among its youth.
“It’s a true kit,” said Rick Fields, extension 4-H science and curriculum coordinator for the U of A Division of Agriculture. “They have to assemble all the parts.”
4-Her’s are given instructions on basic skills they need to build their ROV, like soldering and cutting materials, and then are let loose to begin building. The ROVs are customizable, letting their designer’s creativity flow.
“4-H subscribes to the experiential learning model,” said Fields. “We’ll give them some background information and then they learn by doing.”
By building the ROVs relatively independently, 4-Her’s learn the engineering design model where engineers are presented with a goal, they build something to achieve that goal and then tweak it so it performs at the level it needs to—a process they documented in their engineering journal, said Fields.
The teams will face three contests: the challenge course, the obstacle course and an oral presentation.
In the challenge course, the competitors must get their submersible to retrieve nylon rings and PVC cubes from one platform and deliver and place the rings and cubes on the arms of another platform, all within a specific time period.
For the obstacle course phase, the teams must pilot their submersibles on a roundtrip through a course consisting of five hoops turned at different angles. The competitors won’t know where or how the hoops are positioned until they get to the venue.
The third phase, the oral presentation, is based on the competitors’ engineering notebook. The notebook begins by encouraging youth to solve the problem of how to get involved in SeaPerch; designing a solution to that problem and then doing what it takes to make their submersible the best it can be.
“The notebooks help them approach this as engineers,” Fields said. “They are tasked with documenting all the challenges, obstacles and changes they made to the vehicle.
After the final tweaks were made to ensure that the underwater ROVs are performing at their very best, 14 county 4-H teams made to the trek to the C.A. Vines 4-H Center pool on April 9, competing for a spot at the nationals.
Needed: STEM skills
According to the United States Bureau of Labor Statistics, the STEM fields are the fastest growing occupations in the country. However, student proficiency in these fields in Arkansas is low.
The National Assessment of Educational Progress is the largest uniform, continuing assessment that measures students’ knowledge of different subjects and serves as a yardstick to document student progress overtime. In 2011, 37 percent of Arkansas fourth graders scored proficient in math and 29 percent in science. Those scores drop in middle school, with 29 percent of eighth graders reaching proficient in math and 26 percent in science.
