This lesson will allow the learners to have a hands-on experience investigating an oil spill. They will develop possible solutions to the problems that an oil spill creates for the environment.
One 45-minute class period
The learner will:
- understand the interdependence of organisms on the Earth.
- conduct an experiment to show the problems resulting from an oil spill.
- understand the affects humans have on the environment.
- develop possible solutions to the problems that oil spills create for the environment.
Used motor oil can be recycled and should not go down the sink drain. You can bring the oil from this lesson to any auto service station for recycling. This website has more information: http://www.recycleoil.org/more.html
Anticipatory Set:
Review the lesson from the previous class. Recall that the oil floated on the water and that the oil adhered to the craft stick or feather. Tell them that they are going to experience first hand how oil affects other objects.
- Arrange the learners into groups of two.
- Distribute materials to each group.
- Distribute Attachment One, Oil + Water = A Mess data sheet. Go over it so that the learners are clear on the instructions.
- Ask the learners to follow the instructions on the Oil +Water = A Mess worksheet to complete the investigation.
- After the experiment, discuss the results with the learners.
- Lead a discussion by asking the following questions: Predict what would happen to the wildlife in the ocean and on the land if oil was spilled into the ocean? (The animals and land will be covered in oil or people that use the oil.) Who should be responsible for cleaning the oil from both the animals and the land? Who should be held responsible for the clean up; the owners of the ships and/ or the people that own the oil? What can be done to prevent oil spills in the future (Develop legislation, fines and regulations for the shippers and users of oil.)
Collect the investigation data sheet after the lab activity. Grade each for completeness.

David WallsFollow the instructions to complete this lab activity.
Step #1- Obtain the materials: glass bowl, plastic spoon, drinking straw, water, oil, cinnamon and five (5)
mini-marshmallows.
Step #2- Pour the water into the bowl and add oil to the water.
Observe the water and the oil. Describe three things that you observed.

Step #4- Drop the mini-marshmallows in the bowl. These marshmallows represent animals in the environment.
Observe what happens. Record what the marshmallows look like.

Steps #5- Using the straw have one member of the group blow gently, then harder on the oil. This represents
wind and waves that push oil in nature. Observe what happens to the marshmallows. Record what you see.

Step #6- Try to skim the oil off the surface of the water with the spoon to remove the cinnamon. Observe what
happens. Record the results.

Is the cinnamon easy or hard to remove? _____________________________________________________
How is this activity similar to what occurs when oil is spilled?
