Cricket Wicket Knockdown—Congratulations to the 2020 Fluor Challenge Drawing Winners and High Scorers!

More than 4,900 students from 8 countries participated in the 2020 Engineering Challenge to create a machine capable of repeatedly launching a ball to knock down a wicket. Over 1750 teams built their machines from simple materials (like cups, craft sticks, rubber bands, tape, and cardboard tube) and then competed to see how many times they could knock down a wicket in a three-minute window. We were impressed by the wide range of creative designs, perseverance, and excellent teamwork we saw from the participants. Figure 1 shows a small sample of the hundreds of fantastic knockdown machines students created. All eligible team entries were placed into random prize drawings based on their geographic location. Congratulations to the ten winning teams listed in Table 1 whose names were drawn from the eligible pools! Each of these teams earned $1,000 USD from Fluor for their school or afterschool program.

Meet the Team of Fluor Engineers who Created the 2019 Fluor Engineering Challenge

Fluor holds a Friendly Competition between its engineers every year. The winning team then gets the honor of devising the company challenge for the next year.

Michael Bower, Tina Tajalli, Mark Thies, and Rafael Villegas, four engineers from Fluor's Southern California USA office, are the inspiration behind the 2019 Fluor Engineering Challenge. When they sat down to design the challenge, Michael, Tina, Mark, and Rafael wanted to pay tribute to the local beach culture. What they developed is an engineering challenge based on beach volleyball. In the challenge, two devices keep a ping pong ball (representing a volleyball) in play, going back and forth over a paper net. The result is a fun and sometimes wacky engineering challenge!

Although they come from different engineering backgrounds and have different jobs, Michael, Tina, Mark, and Rafael (along with many other engineers at Fluor) work together on big projects. It takes the combination of their different skills (along with those of other engineers at Fluor) to design and build complex systems like oil refineries and power plants. The ability to work well as a team helped them come up with the Volleyball Machine Challenge! Students can read more about Michael, Tina, Mark, and Rafael's jobs, hobbies, and what got them interested in engineering and then use this special career worksheet to explore the rich world of engineering.

Meet the Team of Fluor Engineers who Created the 2018 Fluor Engineering Challenge

Fluor holds a Friendly Competition between its engineers every year. The winning team then gets the honor of devising the company challenge for the next year.

Tom Wooley, Linh Nguyen, and Temitope Jabaru, three engineers from Fluor's Houston USA office, are the inspiration behind the 2018 Fluor Engineering Challenge. When they sat down to design the challenge, Tom, Linh, and Temitope wanted to pay tribute to Houston's recent history as the location of the 2017 NFL Super Bowl Championship. What they developed is an engineering challenge based on American football. In the challenge, the ball launcher represents the quarterback (the player that throws the ball), and the ball catcher represents the receiver (the player that catches the ball). The result is a fun engineering challenge!

Do you know what process engineers like Tom, Linh, and Temitope do? According to Linh, process engineers are the "architects" of a refinery or plant. "Process engineers determine the design of the plant by figuring out how the plant needs to work in order to take a starting material and transform it into the desired end product," explains Linh. Linh says that process engineers are responsible for determining what equipment is needed, what 'size' everything needs to be, and how the pieces will all fit together. "The design that process engineers develop forms the 'blueprints' (drawings and specification sheets) of the plant," explains Linh. Using the blueprints they create for a project, process engineers then work with other disciplines (like Mechanical, Piping, Control Systems, Electrical, and Construction) to complete the project. According to Linh, collaborating with other teams is how process engineers "bring their design to life and build a successful plant!"

To become process engineers, Tom, Linh, and Temitope all trained as chemical engineers. Despite having different interests and hobbies, they share a love of math and chemistry that led them to their engineering careers at Fluor. Students can read more about Tom, Linh, and Temitope and then use this special career worksheet to explore the rich world of engineering careers.

Students Embrace the Challenge Students who entered the 2017 Fluor Engineering Challenge learned, firsthand, what it means to be an engineer and to collaborate with others to solve a problem and improve a solution. Here are a few examples of what students told us about their experience doing this year's water flow challenge: "I really liked the planning phase of building. It felt good to design methods of water flowing, to see if it worked, and If it didn't, then we would re-design it, and that was the fun part." "Our favorite part of the Flour Engineering Challenge was constructing our design and testing it to see how well it worked." "Our favorite part of the challenge was going through the engineering process and creating our product. When a problem arose, we would change and think of a way out. Working as a team really helped." "My favorite part of this challenge was actually building the model of the Banaue Rice Terraces and how much fun it was to see the water going down with the beads." "We got to experience the problem solving that engineers do when they work." The top 10 scores for the 2017 Fluor Challenge are shown in Table 2. All scores are validated by Science Buddies staff based on submission photos and the Challenge rules. The theoretical maximum for this challenge, given the limitation of 9 levels, is less than nine thousand points. Regardless of score, all entries that met the geographic requirements were entered in the random drawings.

Meet the Team of Fluor Engineers Who Came Up With the 2017 Fluor Engineering Challenge

It is Fluor's tradition to hold an internal Friendly Competition between its engineers every year. The winning team gets bragging rights, ownership of the official trophy for the year, and the honor of devising the next challenge. When Team Wabu, pictured, from Fluor's Manilla office in the Philippines won, they knew what they wanted to do next:

"The team came up with an idea [to] showcase something related to the abundant Filipino heritage, hence, the Banaue Rice Terraces, a man-made, historical structure that the Philippines is very proud of. With this challenge, the team hopes that it can stir up the minds of fellow engineers to come up with their best designs and at the same time have fun."

– Leann, Benson, and Christopher, members of Team Wabu

With the help of three other colleagues from the Manilla office, the engineers on Team Wabu spent many hours perfecting the challenge details. Team Wabu found that there was one major similarity between their everyday engineering jobs, winning the Friendly Competition, and designing the next one—engineering works best as a team effort! The result of their team effort was a rousing competition between fellow Fluor engineers. Now it is your turn to gather your team, collaborate, and have fun!

How the Annual Fluor Engineering Challenge Started

Fluor engineers design and build some of the world's toughest projects, ranging from Shell's Carbon Capture and Storage (CSS) Quest project to the CALTRANS San Francisco-Oakland Bay Bridge Construction project. For a bit of company fun and friendly competition, Fluor engineers challenge each other every year in a global, company-wide engineering competition. Teams of Fluor engineers have been going head to head in yearly competitions for decades, and each year more than 500 engineers around the world participate in the company challenge.

In 2015 Fluor decided to bring the spirit of their yearly employee competition to students. As part of their celebration of Engineers Week, Fluor launched the first annual student-centered Fluor Engineering Challenge to inspire students K-12 to get hands-on with a fun engineering activity during Engineers Week (February 22-28, 2015). With the help of Science Buddies, Fluor's "Moving on the Moon" internal engineering challenge was transformed into an engaging and student-friendly hands-on engineering project that could be easily introduced in a classroom or afterschool program—or done at home. With cash prizes and bragging rights on the line, more than 350 teams stepped up to the plate from around the world. What came next was amazing to watch: a parade of engineering solutions, innovation, and diverse thinking from students focused on creating their own balloon-powered cars with limited materials. Teachers and students alike wrote in to tell us how much fun they had and how eager they were for more challenges:

Ongoing Vision for the Fluor Engineering Challenge

The annual Fluor Engineering Challenge is designed to help students experience how real-life engineers design solutions and to show students first-hand how fun engineering can be. Every year, in partnership with Science Buddies, Fluor transforms one of its own internal employee engineering challenges into a student-centric challenge. The challenge is launched in time for Engineers Week so that teachers and afterschool organizations can use the challenge with their students. The challenge is open to all students around the globe with prizes awarded in a more limited geography. At the end of the approximately four week challenge window the winners and top-scorers are announced and prizes are distributed. The challenge itself lives on though! Previous challenges can be accessed at any time through the Science Buddies website. Individual students and groups are invited to try the previous challenges any time they want—students can measure how their solution stacks up to others students' by calculating their own score and comparing it to that of teams who competed during the challenge window. We invite everyone to try their hand at these Fluor Engineering Challenges:

• 2018 Fluor Engineering Challenge: Ball Launcher
• 2017 Fluor Engineering Challenge: Follow the Flow
• 2016 Fluor Engineering Challenge: Marble Machine
• 2015 Fluor Engineering Challenge: Balloon-Powered Car
