PERFORMANCE TASK STUDENT RESPONSE FORM
TASK: S1 - Oil Spill
Grade 8
Student Name: _______________________________________________
School Name: _______________________________________________
School Code: _________
GENERAL INSTRUCTIONS:
Write your name, school name, and school code on the lines above.
Do not open this test until the directions tell you to do so.
The purpose of this task is to clean up an oil spill using the
absorbent products provided. You will have a total of 45 minutes
to complete this task. You may use up to 20 minutes to complete
the group work, found on the first two pages of this form. When
you finish the group activity, someone from your group should tell
the facilitator. Then you may go onto the individual work found
on pages 3 and 4. You may not talk while you are working on those
pages.
Your group should have the following materials:
- Oil/water mixture (240 mL per student) in a pan
- one 250 mL beaker for each student
- absorbent products: feathers, yarn, sponge, styrofoam
- paper towels
- styrofoam cups
- pencils
GROUP ACTIVITY:
- Divide up the task of testing each absorbent product among members
of your group. You must develop a method to separate the oil from
the oil/water mixture with each material. Separate as much oil
from the mixture as you can.
- Pour the remaining mixture into the beaker and estimate how
much oil was separated. Remember that you began with 240 mL in
a ratio of 3:1 water to oil.
- Use the table below to record the results (data and observations)
of your experiments. Share and collect data concerning all the
materials with members of your group. Discuss the effectiveness
of each absorbent material.
Record information from your group's tests in this chart.

When you are finished with the work on this page, one member of
the group should tell the facilitator that your group has finished
its group work. Then go on to the individual activity. Remember
that you must work alone on those pages. You may not discuss the
questions or share information.
INDIVIDUAL ACTIVITY
- As a scientist, which one of the four tested materials would
you rate best for absorbing oil? Why?

- As a citizen/consumer, would you agree or disagree with the
scientist's recommendations about using such a material to clean
up a large-scale oil spill? Why?

- Identify absorbent material(s), both those tested as well as
any others, that may not be appropriate for clean up of a large-scale
oil spill. Explain why the materials are not appropriate.

- Using your knowledge as well as information you have collected
in this task, devise a way to clean up a real large-scale oil
spill. Be certain to include as much detail as possible concerning
materials as well as reasons for choosing the materials you've
chosen. You may use drawings to help describe your method.
