Tallest Paper Tower—2021 Fluor Engineering Challenge

Congratulations to all 2021 Fluor Challenge Participants!

The 2021 Fluor Challenge was one for the record books! More than 6100 students, the highest number to-date, from 20 countries participated in the 2021 Fluor Engineering Challenge. Students competed to build the tallest possible paper tower that could support a can of food for at least a minute. With the Covid-19 pandemic as the background we were impressed to see how the students embraced the challenge and the circumstances and built an amazing diversity of towers from their homes and socially distanced classrooms. Equipped with just thirty sheets of paper and a roll of tape, kindergarteners through seniors in high school built impressive structures by rolling, folding, taping, and twisting. Ranging from a few centimeters tall to over three meters high it was awesome to see the creativity, perseverance, and problem solving that the students put into their paper towers. Figured 1 shows a small sample of the more than 3500 paper towers built during the competition. Congratulations to all the students who participated; you worked hard and we enjoyed seeing all the towers you engineered!

"I loved that all of my students were interested and engaged in this activity, even those hesitant to participate in STEM. My students typically struggle with independence and thinking for/executing projects themselves. I was so proud of the ideas that they came up with and the effort that each student put in! "

(Teacher, Fairland Program at IU13)

2021 Fluor Challenge Scores by Age

To recognize the hard work students did creating and testing their solutions and to give students a better sense of how their solutions and scores compare to other students of similar age, the tables and graphs below show the top scores and score distribution for submissions from ages up to age 10, 11-14, and 15-18. (Note: The age used for each team is the average age of all members on the team.)

A histogram of scores shows that most elementary school teams scored between 0 and 75 points on the 2021 Fluor Engineering Challenge.

"As a parent, it was wonderful to see my son come up with the idea and put it into motion as well as testing his tower to see what worked and what he needed to fix. He had a great time, dancing, and working on his tower."

"Working as a team and being able to develop our fine motor and communication skills; these skills are extremely important to us as pupils with a Visual Impairment. By completing challenges like this, it gives us time to work on these and have fun with friends at the same time. We problem solve every day of our lives without sight, so tasks like this help us on a daily basis! Thank you."

Students Embrace the Challenge

Students who entered the 2021 Fluor Engineering Challenge had the chance to explore, firsthand, what it means to be an engineer and to work independently or collaboratively with others to construct a stable structure with limited materials. Here are a few examples of what students, teachers, and parents told us about their experience doing this year's Tallest Paper Tower Challenge:

"I loved working hard and engineering this project!"   (The Team, Oregon Episcopal School)
"It was nice to see kids motivated about a project in this tricky hybrid learning year!"   (Teacher, Great Bay E-learning Charter School)
"Oh my goodness—these kids loved this so much! They kept talking about it and trying to find ways to make it even taller. I made them stop when I could not reach the top standing on a desk. Thank you for this great challenge! We loved it!"   (Teacher, West York Area Middle School)
"Seeing my children working together and discussing options for hours in a civil manner was very refreshing!"   (Parent, Homeschool)
"My favorite part of this engineering challenge was working together to make the tallest tower even through the difficult moments."   (Team Avocado, Freeport Middle School)
"As a teacher I loved watching students find success with this project. It brought out students' strengths in design and building. I'm grateful for the lesson plans included with this contest."   (Teacher, Northwood Middle School)
"My first tower was a complete fail! But I kept with it and was so excited I could get something to work! I had so much fun!"   (Team Noah, Palmetto Elementary School)
"Seeing students excited about learning and investigating was heart-warming. To see students running to get into class, staying until after the bell, passionate and engaged about learning again is truly magnificent."   (Teacher, Macon Middle School)

Continue to Challenge Yourself

Even though the 2021 Fluor Engineering Challenge is over, students can still try their hands at the Tallest Paper Tower engineering activity! Simply follow the online instructions to gather materials, design, build, and test your version of the tallest paper tower.

Meet the Team of Fluor Engineers who Created the 2021 Fluor Engineering Challenge

Fluor employees who came up with this year's challenge include engineers (from left to right) Paul Mazur, David Clarke, David Hosking, and Sean Swearns.

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. Paul Mazur, David Clarke, David Hosking, and Sean Swearns, four engineers from Fluor's Greenville, South Carolina office, are the inspiration behind the 2021 Fluor Engineering Challenge. When they sat down to design the challenge, David, Paul, David, and Sean wanted to pay tribute to a tower-shaped baseball monument scheduled to be built in Greenville. What they developed is an engineering challenge based on the best way to construct a tower with limited materials. Science Buddies' staff scientists took this core idea and simplified it for a K-12 audience.

Curious what it is like to be an engineer? Read our interviews with David Clarke, David Hosking, and Sean Swearns.
