1 Oil Spill Lesson Lesson Objectives: Content Standard A: Scientific Inquiry Students will design and conduct a scientific investigation Content Standard F: Science in Personal and Social Perspectives Students will understand the risks associated with chemical hazards such as pollutants in water. Time Needed: Day 1: Engage with reading Prince William aloud to students. Day 2: Explore and Explain with reading Oil Spill aloud to students and oil spill cleanup checkpoint lab. Day 3: Elaborate with animal rescue. Day 4: Evaluate with thank a rescuer. Materials Needed: In advance, make black oil by adding 8 teaspoons of powdered black tempera paint in a gallon jug half full of vegetable oil. With the lid tightly in place, share the jug to mix the powder with the vegetable oil. This will make enough for 8 teams. Newspaper Disposable aluminum pie pans (3 per team) Rocks no bigger than a deck of cards (3 per team) Leafy carrot or celery tops or plastic aquarium plants (3 per team) Pipe cleaners Water 3 cups for collecting removed oil for measuring Metric measuring cups Red cup and green cup with openings taped together (1 per team) Zipper baggies filled with supplies (1 per team) *spoon *fork *50 cm. of yarn *10 cm strip of nylon stocking

2 *cotton ball *disposable pipettes *coffee filter *5 cm wide strip of paper towel Engage: Inferring: Have students gather into a circle and read aloud Prince William. *Ask: What do you think this book might be about? *Ask: Who do you think Prince William is? Questioning: Tell the students you will be letting them know what you are wondering while reading the book because good readers ask questions. Stop reading periodically to ask questions you are wondering about: * Ask: What would an oil covered beach look and smell like? *Ask: Why does Denny hear a baby crying on the beach? *Ask: What would it be like to pick up a slippery baby seal? *Ask: Will Prince William survive? Remember : Make sure to read the author s note at the end of the book, which explains that Prince William is based on true events and that schoolchildren really did help with the seal recovery efforts. Text to self: Think Pair Share: *Share a time you have saved an injured animal. Ask students if they have ever helped an animal like Denny helped Prince William. Allow a minute or two for students to share their experiences with a partner. Explore and Explain: Introduce the author and illustrator of Oil Spill. Hav e students write down the methods and materials used by oil spill cleanup crews as you read the book to the class. *Ask: What methods and materials were described in the book?

3 Using booms, skimmers, and pads; setting the oil on fire; spreading chemicals; spraying the shore; adding bacteria; or taking no action. *Ask: Which method do think works the best? Why? *Ask: Are there any disadvantages to any of these methods? Pads are difficult to dispose of; fire sends smoke and gas into the air and leaves ash in the water; chemicals add poison to the water; hot spray pushes water farther into the rocks and sand; and using bacteria requires huge amounts of it. Oil Spill Cleanup Checkpoint Lab: Divide the students into groups of four. Give each member of team a copy of the Oil Spill Cleanup Checkpoint Lab. Explain that they will be following the directions on the sheet. As they are working, they should keep their cups green side up unless they encounter a problem. Each member of the group is responsible for recording data and writing responses. Before you give a team a check mark or stamp to move on, informally evaluate the students by asking probing questions. When all the groups are finished with the lab, discuss the following questions: *Ask: What did you learn about designing an experiment? *Ask: Would you make any changes in your experimental design? *Ask: Can you propose any new methods for cleaning up oil spills? *Ask: What do you think it would be like to clean up a real oil spill like the Exxon Valdez spill we have been reading about? Elaborate: Animal Rescue: It may be necessary to reread pages of Oil Spill. Then ask the following: * Ask: What types of animals were harmed by the oil spill? seabirds such as ducks and geese, fish, shrimp, crabs, sea otters, sea lions, harbor seals, and killer whales *Ask: How do oil spills harm birds?

4 The oil sticks to their feathers so they can t swim or fly *Ask: How do oil spills harm fish, shrimp, and crabs? Oil gets into their bodies and poisons them *Ask: How do oil spills harm sea mammals? They swallow oil and breathe poisonous fumes. The oil also coats their bodies. It may be necessary to reread pages 10 (about the doctor and volunteer), 19 (about the other animals being washed), and 20 (about Denny finding the empty incubator). Then ask: *Ask: Imagine that you are cleaning a real, live animal that has been oiled. What things would you need to consider to keep you and the animal safe? *Ask: What would your day be life if you were an animal rescuer? *Ask: What would you enjoy about being a rescuer? *Ask: What parts of the job would be difficult? Pass out the Animal Rescue sheet. Tell the students to imagine they are animal rescuers. Have them write a descriptive story detailing their rescue experiences. They should draw a picture to illustrate their story. Evaluate: Thank a Rescuer Pass out the Thank a Rescuer sheet. Students will write letters to oil spill animal rescue organizations thanking the oil response team employees and volunteers. Use the rubric below to evaluate the letters. Inquiry Place: Have students brainstorm investigative questions: *Ask: Which brand of detergent is best for cleaning oiled material? *Ask: Which is best for insulating a marine animal: fur, feathers, or blubber? *Ask: Do all types of oil float on water? Of the following types of oil, olive oil, corn oil, and baby oil, which is the most dense? The least dense?

5 Students can select a question to investigate as a class, or have groups of students vote on the question they want to investigate as teams. After they make their predictions, students can design an experiment to test their predictions. Students can present their findings at a poster session. *This lesson was adopted from the Picture Perfect Science Lessons book by Karen Rohrich Ansberry and Emily Morgan. NSTA press.
