hold Overall Champion Trophy from National Fluid Power Challenge

Twelve eighth grade students from Mitchell Middle School's Technology Education class, "Gateway to Technology," competed in the National Fluid Power Challenge Championship at Milwaukee School of Engineering (MSOE). They were led by their Technology Education teacher, Keith Kohlmann and school counselor Kate Mascarette.
All Mitchell students in the "Gateway to Technology" classes built fluid power machines as part of "Project Lead the Way," a national standard for Science, Technology, Engineering and Math Education. The program, sponsored by the National Science Foundation, prepares students for engineering careers.
Twelve students were chosen for the three Mitchell teams, each of which comprised two boys and two girls. They had four weeks to develop and build, during class, a working prototype of a four-function, three-axis hydraulic lifting machine. Their machines had to meet some very tight specifications.
A camera crew from Channel 10 has been following their progress for the last month as part of a documentary called, "Innovations in Education." It will be a reality show illustrating the excitement of science and technical education using real students. In November they filmed the Mitchell kids in action at MSOE and again in the classroom last Wednesday.
Each team had to submit a technical report on their machine as part of the overall point total. The 14-page reports were finished at 3:30 on Thursday. On Friday, Dec. 11, the Mitchell teams joined 14 teams from the Milwaukee area at MSOE for the competition. Starbuck Middle School also participated, sending four teams.
All teachers left the room for a tour of the MSOE fluid power engineering labs, and the students were then given three hours to build a second version of their hydraulic lifting machine, using only their tools, a box of materials and the technical report containing the plans they drew. As they worked, judges graded the groups on teamwork, cooperation, technical skills and answers to quiz questions.
The students worked non-stop, measuring, cutting wood, gluing parts and checking their work against their plans. They worked through lunch, with some teams placing the last components and trouble-shooting problems in the final seconds.
The teachers returned to watch the teams operate their machines in the Fluid Power Challenge. Points were scored for each object successfully picked up and moved with fluid power during a two-minute round. There were many tense moments; machines broke down, strategies failed. A month's worth of preparation led up to this final test.
Mitchell Team 3 went first, flaming out when they blew a hydraulic cylinder, scoring zero points.
Mitchell Team 2 scored early by placing a three point cylinder on the delivery shelf, but then lost all their points when they knocked it off trying for a second three-point score.
The teams from Racine Starbuck and Greenfield Bilingual Academy turned up the heat by repeatedly scoring points during their two-minute rounds. They were tied for first place with 8 points each.
use hydraulic actuators to operate their fluid power machine.
Mitchell Team 1 drew the last round. A last-minute change in their communication plan got them off to a shaky start and they barely scratched together three points in the first minute. With time slipping away, they regrouped and scored six more points in less than 20 seconds, putting them in the lead with nine points.
While the students cleaned up, the judges totaled each team's points in the areas of design, structural stability, teamwork, technical knowledge, engineering portfolio and machine performance, deciding the winner in each category, as well as the overall champion.
Mitchell Team 2 (Tom Vertz, Hallie Senzig, Tacoiya Anderson and Josh Ertl) took home the "Best Engineering Portfolio" trophy.
Mitchell Team One (Elizabeth Brau, Holly Munch, Jason Bernhardt and Sam Kohlmann) received the "Overall Champion" First Place award by posting the highest point totals in all areas of the competition.
NFPA participants from Mitchell Middle School and their teachers are invited to attend the premiere of "Innovations in Education" in January at Discovery World in Milwaukee. The video is scheduled for nationwide distribution to educators and classrooms this spring.
The Fluid Power Challenge is a skills competition intended to expose students and teachers to engineering problem-solving using fluid power technology. Students then are encouraged to select high school courses in math, the sciences and technology that will lead to post-secondary studies and, eventually, careers in fluid power.
Industries in the Racine area have had a long history of invention and innovation in the fluid power industry. Local industry sponsors of the National Fluid Power Challenge include: Air-Logic, Bosch Rexroth, and Racine Federated, Inc.
