Pipeline Challenge
This lesson focuses on how engineers develop pipeline systems to transport oil, water, gas, and other materials over very long distances. Students work in teams to develop a pipeline system to transport both a golf ball and ping pong ball across the classroom terrain.
- Learn how civil engineers approach large scale problem solving.
- Learn how engineering teams address problem solving.
- Learn about teamwork and working in groups.
Age Levels: 8-18
Build Materials (For each team)
Required Materials (Table of Possibilities)
Assuming a 15′ x 15′ room, allow for about 20 feet of piping per team
- Paper towel, wrapping paper and toilet paper rolls (or roll up thin sheets of cardboard) – Tubes must be large enough to accommodate a golf ball and ping pong ball.
- To minimize the issue of balls becoming stuck in the tubes, consider cutting the tubes in half to serve as “open” piping.
- Packing or duct tape for connections
- PVC tubing, if budget allows
Optional Materials
- If giving students an environment challenge. Use items to represent environmentally protected areas (plastic/stuffed animals, construction paper for water, rocks, or other hazards)
Testing Materials
- Golf ball (or similarly sized rubber ball)
- Ping pong ball

Materials
- Golf ball (or similarly sized rubber ball)
- Ping pong ball
Process
Test the pipeline designs by first rolling the golf ball through and then, the ping pong ball until each one stops. Students should measure and document how far each ball rolled until it stopped.
Design Challenge
You are a team of engineers given the challenge of developing a pipeline system to transport a golf ball and a ping pong ball from one side of your classroom to the other. You will need to incorporate four angles into your design, one of which is a right angle (90 degrees). The difference in height from one end of your pipe to the other can be no more than 18 inches. Your teacher may identify environmentally protected areas, water, or other hazards in your classroom that you’ll have to consider in your plan.
Criteria
- Incorporate 4 right angles into design
- One must be a right angle (90 degrees)
- Difference in height from one end to the other can be no more than 18 inches
Constraints
- Use only the materials provided
- Break class into teams of 2-4.
- Hand out the Pipeline Challenge worksheet, as well as some sheets of paper for sketching designs.
- Discuss the topics in the Background Concepts Section.
- Review the Engineering Design Process, Design Challenge, Criteria, Constraints and Materials.
- Instruct students to start brainstorming and sketching their designs. Before they begin, ask them to consider the features of the classroom such as doors, desks, tables, trash cans or other obstacles.
- Provide each team with their materials.
- Explain that students must design and build a pipeline to carry a golf ball and a ping pong ball across your classroom. They should include four angles in their design, one should be a right angle (90 degrees). There should be a height difference of no more than 18 inches from the beginning to the end of the pipeline. If you are including an environmental challenge, be sure to identify the environmentally protected areas in the classroom.
- Announce the amount of time they have to design and build (1 hour recommended).
- Use a timer or an on-line stopwatch (count down feature) to ensure you keep on time. (www.online-stopwatch.com/full-screen-stopwatch). Give students regular “time checks” so they stay on task. If they are struggling, ask questions that will lead them to a solution quicker.
- Students meet and develop a plan for their pipeline. They agree on materials they will need, write/draw their plan, and present their plan to the class.
- Teams build their designs.
- Test the pipeline designs by first rolling the golf ball through and then, the ping pong ball.
- Students should document how far their ball rolled through the pipe before stopping.
- As a class, discuss the student reflection questions.
- For more content on the topic, see the “Digging Deeper” section.
Student Reflection (engineering notebook)
- What challenges did you face in executing your pipeline?
- Did you find you needed to rework your original plan when you began building the real pipeline in the classroom? If so, how did your pipeline change?
- Did you find your pipeline was more effective using the ping pong ball or the golf ball? Why do you think this was true?
- Which pipeline developed by another “engineering” team did you think worked best? Why?
- If your design were scaled up to a real pipeline, do you think you would need pumps to keep the materials flowing through your system? Why or why not? And, if so, how many pumps would you add, and where would you put them?
- Do you think your pipeline design would work if you used it to transport water? Feathers? Butter? Why or why not?
- Did you find that there were many ways to solve this challenge? If so, what does that tell you about the engineering designs of real pipelines?
- Do you think you would have been able to create a successful pipeline as easily if you had not been working in a team? What are the advantages of teamwork vs. working alone?
- How do you think engineers on the Baku-Tbilisi-Ceyhan Pipeline determined that they needed eight pumps to run the length of the project?
- How do you think engineers working on the Alaskan Pipeline attempted to avoid negative environmental impact in Alaska? Did they succeed?
Time Modification
The lesson can be done in as little as 1 class period for older students. However, to help students from feeling rushed and to ensure student success (especially for younger students), split the lesson into two periods giving students more time to brainstorm, test ideas and finalize their design. Conduct the testing and debrief in the next class period.
Pipeline transport is a transportation of goods through a pipe. Most commonly, liquid and gases are sent, but pneumatic tubes that transport solid capsules using compressed air have also been used. As for gases and liquids, any chemically stable substance can be sent through a pipeline. Therefore sewage, slurry, and water pipelines exist; but arguably the most important are those transporting oil and natural gas.
Baku-Tbilisi-Ceyhan Pipeline
The Baku-Tbilisi-Ceyhan pipeline (sometimes abbreviated as BTC pipeline) transports crude petroleum 1,776 km from the Azeri-Chirag-Guneshli oil field in the Caspian Sea to the Mediterranean Sea. The total length of the pipeline in Azerbaijan is 440 km long, in Georgia it is 260 km long and in Turkey is 1076 km long. There are 8 pump stations through the pipeline route. The construction of the BTC pipeline was one of the biggest engineering projects of the last decade. It was constructed from 150,000 individual joints of line pipe, each measuring 12 m (39 ft) in length. It has a projected lifespan of 40 years, and when working at normal capacity, beginning in 2009, will transport 1 million barrels (160 000 m³) of oil per day. It has a capacity of 10 million barrels (1.6 million m³) of oil, which will flow through the pipeline at 2 m (6 ft) per second. The pipeline will supply approximately 1% of global demand.

Trans-Alaska Pipeline System
The Trans-Alaska Pipeline System is a major U.S. oil pipeline connecting oil fields in northern Alaska to a sea port where the oil can be shipped to the Lower 48 states for refining. The main Trans-Alaska Pipeline runs north to south, almost 800 miles (1,300 km), from the Arctic Ocean at Prudhoe Bay, Alaska to the Gulf of Alaska at Valdez, Alaska, passing near several Alaskan towns. Construction of the pipeline presented significant challenges due to the remoteness of the terrain and the harshness of the environment it had to pass through. Between Arctic Alaska and Valdez, there were three mountain ranges, active fault lines, miles of unstable, boggy ground underlain with frost, and migration paths of caribou and moose. Since its completion in 1977, the pipeline has transported over 15 billion barrels (2.4 km3) of oil.
West-East Gas Pipeline Project
The West-East Gas Pipeline is a 4,000-kilometers long pipeline, which runs from Lunnan in Xinjiang to Shanghai. The pipeline passes through 66 counties in the 10 provinces in China. The construction of the West-East Gas Pipeline started in 2002 and it was put into operation on 1 October 2004. The pipeline is owned and operated by the Natural Gas and Pipeline Company, subsidiary of PetroChina. The gas will be used for electricity production in the Yangtze River Delta area.
