Materials
- Students use the container, water and “oil” listed in the required materials section
Process
Using the containers, water, and “oil” – Each team first demonstrates how their system has contained the oil spill. Then, they demonstrate how their system cleans up the oil spill.
Using a scale of 0-4, teams should rate how well each system cleaned up the oil spill. The goal is to rate a “0.”
Water is completely clear of all oil = 0
About a quarter of the oil remains = 1
About half of the oil remains = 2
About three quarters of the oil remains = 3
No change, water is as oily as at the beginning of the challenge = 4Engineering Design Challenge
Design Challenge
You are part of a team of engineers who have been given the challenge of first containing and then cleaning up an oil spill. You will have many materials available to you, but will have to come up with a strategy to remove as much oil as possible.
Criteria
- Contain as much oil as possible
- Clean up as much oil as possible
Constraints
- Use only the materials provided
- Teams may trade unlimited materials
Activity Instructions & Procedures
- Break class into teams of 2-3.
- Hand out the Oil Spill Solutions 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. They will need to outline their containment process and materials, and outline their clean up process and materials.
- Provide each team with their materials.
- Explain that students must develop a system that contains an oil spill and then a system that cleans up the oil spill. The goal is to remove as much oil as possible from the spill.
- 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 containment and clean up systems. They agree on materials they will need, write/draw their plan, and present their plan to the class. Teams may trade unlimited materials with other teams to develop their ideal parts list.
- Teams build their designs.
- Using the containers, water, and “oil” – Each team first demonstrates how their system has contained the oil spill. Then, they demonstrate how their system cleans up the oil spill.
- Using a scale of 0-4, teams should rate how well each system cleaned up the oil spill. The goal is to rate a “0.”
Water is completely clear of all oil = 0
About a quarter of the oil remains = 1
About half of the oil remains = 2
About three quarters of the oil remains = 3
No change, water is as oily as at the beginning of the challenge = 4 - As a class, discuss the student reflection questions.
- For more content on the topic, see the “Digging Deeper” section.
Student Reflection (engineering notebook)
- Did you succeed in removing all the oil from the “oil spill?” What was the score your team achieved?
- If your system failed, what do you think went wrong?
- Describe a system another student team created that you thought worked well. What did you do differently?
- How did your decisions on engineering trade-offs differ from that team? What goals or priorities for your system did you put above others?
- Did you decide to revise your plan while actually doing the containment or clean-up? Why? How?
- Why might a team of environmental engineers change their planned approach to an oil spill clean-up once they arrived on the site? Do you think it is common that professionals change their plans while on the job?
- If you had to do it all over again, how would your team have improved your containment system? Why?
- If you had to do it all over again, how would your team have improved your clean-up system? Why?
- Do you think that experience with prior oil spills would make a team of engineers more able to address the next unexpected one?
- Now that you have learned about the different trade-offs engineers must factor into a product or system, if you were designing a new rail-based oil transportation system, what considerations would you have to balance in your new design (consider costs, environmental issues, public health, speed of transport)?
- What other materials do you think would have helped speed up your containment or clean-up?
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.

Background Concepts

What is an Oil Spill?
An oil spill is an accidental release of liquid petroleum hydrocarbons (usually during transportation of oil) into the environment. Oil spills usually refer to the release of oils into water, but of course an oil spill can take place on land as well. While spills can take place quickly, as when a ship sinks, or a leak occurs in a pipeline, the cleanup can be a long term project.
Impact on the Environment
Birds are one of the creatures impacted by oil spills. Oil can sink into and reduce the functionality of bird feathers. A bird’s feathers provide insulation, so a bird exposed to oil will be exposed to temperatures they are not used to. It also makes it difficult for a bird to float or fly…so the bird will be more vulnerable to animals of prey, or the bird may not be able to move to find food or clean water. Birds try to clean themselves, and if they do they are likely to ingest some of the oil which can cause damage to internal organs. Most birds impacted by an oil spill die unless humans step in and help clean them. Many organizations work to save these animals. Marine mammals such as seals and otters gain insulation benefits from their fur. As oil permeates the fur, they are potentially exposed to temperatures beyond their normal range. It is important to act quickly when a spill occurs to lessen the impact of the spill on the natural environment. Environmental engineers are often called upon to come up with planned solutions in advance of a spill, or to customize systems bases on a specific event.
Engineering Trade-offs
In order to reduce the chances of an oil spill, engineers have developed new ship designs with double — and even triple hulls. The oil is stored in the most interior hull, so that if there was a leak, it would be captured in the next outer hull. Of course, these multiple hulled ships are more expensive to build and operate, so a company will have to weigh the advantages and disadvantages of ship engineering in order to come up with a plan that meets safety requirements, but also does not increase the cost of the shipped product more than the market can bear.
Clean-up Methods
There are many types of cleaning methods used for spills, including:
- Bioremediation: using microorganisms or biological agents to break down or remove oil
- Dredging: some oils are actually denser than water, and would sink. These would require cleaning below the surface of the impacted water.
- Skimming: can be effective areas where the water is calm.
- Dispersion: materials such as some detergents can disperse oil into smaller clusters that may be easier to remove than larger areas. However, the detergents can sink deeper into the water than oil does, so it may cause harm deeper in the water while reducing negative environmental impact on the surface.
- Burning: controlled burning can often eliminate a large proportion of oil in water, but of course requires great care to avoid having the fire spread. The burning oil can also cause air pollution.

Engineer Your Own Oil Spill Solution
You are part of a team of engineers who have been given the challenge of first containing, and then cleaning up an oil spill. You will have many materials available to you, but will have to come up with a strategy to remove as much oil as possible.
Planning Stage
Meet as a team and discuss the problem you need to solve. Then develop and agree on a plan for your containment system. Next develop a plan for cleaning up the oil you have contained. You may have to consider stages or steps you might take and determine which order you will execute different steps. You have been provided with many items you may use for your system. You don’t need to use all the items, and should only use those that you think will work the best. Write a description of your containment and clean-up systems in the boxes below. Draw a sketch of what you plan to do. Be sure to indicate the materials you anticipate using. Present your design to the class. You may choose to revise your teams’ plan after you receive feedback from class.

Preparation Phase
Gather all the materials you plan to use, and consider how you will use them and what steps might need to be taken. You may need to ask for additional materials during this phase as you consider how much oil you have to clean-up!
Testing Phase
Each team will have a chance to test their containment and clean-up systems on a similar “oil spill.” Be sure to watch all the methods and observe the different approaches your classmates have “engineered.” See which procedures worked best — it may be that certain parts of a procedure worked better than others. Each system will be scored on the following scale to determine success.
Water is completely clear of all oil About a quarter of the oil remains About half of the oil remains About three quarters of the oil remains No change, water is as oily as at the beginning of the challenge 0 1 2 3 4 Evaluation Phase
Evaluate your team’s results, complete the evaluation worksheet, and present your findings to the class.
- Did you succeed in removing all the oil from the “oil spill?” What was the score your team achieved?
- If your system failed, what do you think went wrong?
- Describe a system another student team created that you thought worked well. What did you do differently?
- How did your decisions on engineering trade-offs differ from that team? What goals or priorities for your system did you put above others?
- Did you decide to revise your plan while actually doing the containment or clean-up? Why? How?
- Why might a team of environmental engineers change their planned approach to an oil spill clean-up once they arrived on the site? Do you think it is common that professionals change their plans while on the job?
- If you had to do it all over again, how would your team have improved your containment system? Why?
- If you had to do it all over again, how would your team have improved your clean-up system? Why?
- Do you think that experience with prior oil spills would make a team of engineers more able to address the next unexpected one?
- Now that you have learned about the different trade-offs engineers must factor into a product or system, if you were designing a new rail-based oil transportation system, what considerations would you have to balance in your new design (consider costs, environmental issues, public health, speed of transport)?
