Are
You Into Heavy Metals?
Scenario

|
A recent hurricane caused the flood gates
to be opened on the Conowingo Dam.
This caused extensive flooding in the Aberdeen Proving Ground
which released
heavy metal contaminants into the various water supplies (wells,
bay, ponds etc).
Your job as an EPA chemist is to evaluate the contamination spill
and determine
the long term effects to the environment.
Read about mercury poisoning in the population of
Minimata
Bay, Japan.
OR
Read about the poisioning of Love
Canal, New York.
|
Task and Product
|
Working in small groups, you will research
various heavy metals to complete your
investigation chart. Once the chart has been completed you will
then write a community
reponse plan or create a music video using your findings.

Question

|
Essential Question:
How would
the study of heavy metal contamination help us
plan for future chemical spills?
|
Subsidiary questions:
- How do heavy metals affect various organs
in the body?
- Describe various methods by which heavy metals
can posion the human body.
- What are some of the long term effects in
humans?
- How do communities clean up or contain chemical
spills?
- Describe some methods of treatment for heavy
metal poisoning in humans.
|
Gather and Sort

|
Gather information about heavy metals from a variety
of sources.
Sort your research findings using a graphic
organizer or note cards. Be sure
to avoid plagiarism
and keep track of your resources for a bibliography. |
Organize

|
Analyze
your completed project.
- Have you adequately completed the Investigation
Chart?
- Have you read about previous heavy
metal contaminations?
- Which metals seem to be of most concern
to you?
Synthesize your
findings.
- What new insights have emerged?
- How will you incorporate the most important aspects of your
research
into your plan?
- Complete the Investigation Chart.
Evaluate the effectiveness of your research for the
task.
- Have you gathered sufficient details
about the heavy metals on your
Investigation chart in order to write your plan?
- Is your research reflected in the plan?
|
Conclusion

|
Each group will share the information from their contaminant research to complete the Heavy Metal Chart. Each group
will turn in their completed plan to the teacher in the form
of a Community Action Plan. The teacher may choose to
have students present/share highlights of their community response
plan to the class.
Reflection and/or Extension Activities:
Complete the BCPS Chemistry Lab: Laws of Conservation of Mass.
As a culminating activity each student will prepare a Constructed
Response
answering the essential question:
How would the study of heavy metal contamination
help us plan for future
chemical spills?
Remember to support your responses with the information you have
gained
from your research and that of the other groups.
