KILLING KILLER RAIN
PROJECT
OVERVIEW/SETTING:
Acid Rain and
Environmental Health: Why Study Acid Rain?
I teach the history and current events
of Canada and Latin America to seventh grade students at a private school. To
participate in the My Environment, My
Health, My Choices curriculum development project, I needed a topic related
to at least one of these regions. From a history perspective, acid rain
interested me because it has impacted the last 25 years of Canadian history, it
affects both Canada and the United States (with each country causing problems for
the other), and it is a vital issue to both New York State and its provincial
neighbor, Ontario, Canada. Acid rain is
also a current topic; in the last few years, New York and other states have
taken legal and diplomatic steps to address the issue
This
social studies unit was designed as one part of an interdisciplinary
problem-based environmental health unit for middle school students. But, if teacher expectations for student
performance are raised, the unit could easily be used for high school students. I have used the entire unit in my social
studies class. Because of the unit’s
interdisciplinary approach, portions of this unit could be completed in science
and English classes. For example, the
oral reports and letter writing could be done during English classes. Research on acid rain, perhaps with
supplementary laboratory activities, could be done in science classes.
This
unit explores a complex, current topic that shows the international,
“borderless” nature of certain environmental health issues. It is particularly
suited to a social studies curriculum involving the study of Canada and the
United States. In addition to the basic
science knowledge required to understand acid rain, this unit also requires
students to explore human health and environmental justice issues, and to use
geography, research, writing, and public speaking skills. As an interdisciplinary unit, it also
incorporates English language and science standards.

INTRODUCTION:
This 11- day unit uses
integrated/interdisciplinary problem-based learning to focus on acid rain: its
sources, environmental effects, health effects, economic impact, political
impact, and potential solutions in the United States and Canada. The introductory problem, “Killing Killer
Rain,” asks students to research specific questions about acid rain in order to
make recommendations to government officials about the future of coal-burning
power plants, a major source of the acid rain. Questions raised are:
Students
are challenged to define the problem, to work in teams to research questions
related to the problem, and to present their reports and recommendations to the
class. For this unit, the class is divided into six research groups, each with
students of mixed ability. Each group researches and reports on acid rain from
a different perspective. Each group is assigned
one of these six areas:
1. Sources,
Geography and Geology
2. Potential
Solutions
3. Environmental
Impact
4. Economics
5. Politics
6. Human
Health
Within each group, individual students do research on specific
questions and then report their analysis of the research to others in their
group. The group then uses this
information to make recommendations for problem solutions and presents a report
on their recommendations to the class.
GOALS &
OBJECTIVES:
The goals and
objectives of this curriculum are:
UNIT OVERVIEW:
Day One: Introduction to Environmental Health
Students discuss the definition of
environmental health in small groups.
They brainstorm a list of things they could do to improve the
environment and reduce environmental health risks.
Day Two: Canadian Geography
Using a cooperative classroom activity
and a homework assignment, students establish their current level of knowledge
of Canadian geography and gather new information. A classroom game is used to
enhance knowledge.
Day Three: Exploring the Problem as a Class
The class reads and discusses the Killing Killer Rain scenario.
Day Four: Exploring the Problem in Small Groups
Students are divided into six groups of
three to four students to brainstorm questions about acid rain and
environmental health. They also take a Canada Map Quiz.
Days Five, Six
and Seven: Researching
Solutions to the problem
Students explore the question: How would students advise US and Canadian
officials about future energy policy regarding acid rain? Groups are assigned a topic with related
questions. They develop a research plan.
They work in groups to conduct Internet and library research, or
organize the results of their research, and to develop group reports.
Days Eight,
Nine and Ten: Presenting research
Groups present their findings and
recommendations to the class. After
group reports are presented, discuss what students have learned and how
students can make a difference.
Students are then asked to write a draft letter stating their opinion
regarding whether new coal-burning power plants should be built and whether
anti-pollution requirements for older power plants should be reduced.
Day Eleven: Write a Letter
Teacher returns the draft letters to
students for peer review and revision. Students then write final letter and
mail it to public officials.
UNIT ASSESSMENT:
Students
are graded for this unit based primarily upon the individually written summary
reports contributed to their groups, the group presentations, the letters
written to a public official, and participation in class discussions and group
work.
TEACHER
REFLECTION:
By teaching this Environmental Health
unit, I achieved my primary goals. My students gained an understanding of the
international nature of some environmental issues through their study of acid
rain, they realized the complexity of the issue from the economic, health, and
political perspectives, they noted the different ways Canada and the U.S.
approached the same issues, they sharpened their research and public speaking
skills, they reinforced their U.S.-Canada geographical knowledge, and, perhaps
most importantly, they came to understand the importance of discussing and
taking action on public issues. In fact, as an added bonus, the class received
a congratulation letter from The Adirondack Council in the spring term for
their participation in the process that led to a significant U.S. EPA ruling
that should result in major cuts to emissions that cause acid rain.
The Killing
Killer Rain scenario engaged my students primarily because most of them had
their own stories from the Blackout of 2003 to share. The geography component
establishes, early on in the unit, the shared boundaries and natural features
of Canada and the U.S..
I was pleased with the level of
sophistication many of the students reached in their understanding of the
issues on all sides of the acid rain debate. Some of the reports were quite
comprehensive. Moreover, many of the students used the information they had
discovered quite well (and passionately) in their letters to public officials
regarding energy and environmental policies currently being debated. Many also
heard back from the public officials they wrote, including President Bush,
Senator Charles Schumer, and Representative Louise Slaughter.

Day One: An Introduction to Environmental Health
Description: This class session is intended to
generate student interest and excitement in the Killing Killer Rain
environmental health unit as a unique learning experience.
Objective: Students will
demonstrate comprehension and evaluation skills by defining the term
“environmental health” and reflecting upon its relationship and importance to
our lives.
Time allotted: One class
period.
Materials:
·
Large sheets of paper (one per group)
·
Tape, if paper is not self-adhesive
·
Markers (one per group)
·
List of students assigned to each of the six groups
·
Blackboard, white board, or paper on wall for brainstorming
·
One Homework Canada
Map (Handout #1) per student
Activities:
1.
Model how to develop a working definition with the whole
class by working through an example. A
possible word to use for this exercise is “home economics.” After writing the
term on the board, ask students to define “home” first, and write suggestions
on the board. Do the same for the term “economics.” Ask students to suggest a
definition for the entire term based upon their definitions of each word.
2.
Group students into six teams of students (3-6 per team
depending on class size). Provide each group with a large piece of paper, a
marker, and a place in the room to work. Direct each group to take 10 minutes
to compose its own working definition of “environmental health.”
3.
Call the whole class back to order. Ask for a volunteer from
each group to share its definition of “environmental health”, and write the
definitions on the board. Work with the class again to craft a single working
definition of the term “environmental health.”
4.
As a whole group, take another 10 minutes to brainstorm a
list detailing things that students think might impact our environmental health.
Compile the list on the board.
5.
Using the new list on the board, groups should work together
to make alterations or additions to their original, working definitions of “environmental
health”. Discussion can run until the completion of the allotted time.
Homework for next class: Hand out copies of Handout #1 Homework Canada Map to each student. Explain that their homework
will be to fill in an extensive map of Canada. Students may use any resources
they can find, including textbooks, atlases, wall maps, encyclopedias, and the
Internet. The information from this assignment will be used for a game on Day
Two.
Day
Two: Canada off the Top of Your Head - Geography of Canada Game
Description: This lesson
establishes the geography of Canada as it relates to the United States. It is optional if your students already
comprehend geographical relationships between Canada and the United
States. Using a simple cooperative
classroom activity and their homework assignment, students discover their
current levels of knowledge about the geography of Canada and gather new
information.
Objectives: Students will
use identification and research skills in a collaborative activity to help them
learn anew or reinforce their knowledge of Canada’s geography and introduce
geographical terms they will need to understand and discuss Canada and the
Canada-U.S. acid rain issue.
Time
allotted: One and a half
45-minute sessions or a total of about 60 minutes.
Materials:
·
Wall map of Canada with masking or medical tape covering
names of provinces, territories and their capitals, U.S. states bordering
Canada, and major Canadian water bodies
·
Five copies of Canada
Geo Game (Handout #2), a fill-in-map of Canada showing the boundaries and
locations of provinces, territories, capitals, U.S. states bordering Canada,
and major Canadian water bodies
·
One answer key to Canada
Geo Game (for teacher)
·
Access to wall maps of North America, atlases,
encyclopedias, and the Internet
·
One answer key to Homework
Canada Map (for teacher)
·
One red pen for each student
·
Board and chalk or markers
·
Prizes (for example, a “homework pass” or candy)
Activities
1.
Explain to students that you will not be collecting their
homework until later in the period. Ask them to keep their homework sheets out
of sight until then.
2.
Divide students into mixed groups and allow them to choose
their own group names and secretaries. On the board, make a column for each
group.
3.
Hand out one copy of Canada
Geo Game to each group.
4.
Allow student groups 10 minutes to fill in the blanks on
their maps with the names of as many provinces, their capitals, bordering U.S.
states, and water bodies as the group can generate without looking at their homework or any outside resources,
including books, wall maps, the Internet, etc. Group secretaries write in the
answers.
5.
Call the class to order, allowing students to stay in their
groups. Instruct the group secretaries
to grade their groups’ fill-in maps “on their honor.” Using your Canada Geo Game answer key and a wall
map of Canada with tape over the labels, ask students to help identify each
province, territory, and their capitals, U.S. states bordering Canada, and
important bodies of water in or bordering Canada. After a place is identified
correctly, pull the tape off that label and ask the secretaries whether their
groups identified that place correctly.
For each place identified correctly, the group gets 5 points. Keeping a
running tally of points, continue until all provinces, territories and their
capitals, U.S. bordering states, and important water bodies have been
identified. The secretaries should write in answers that their groups did not
get. Provide answers for those places no groups identify.
6.
Members of the group with the most points receive a prize
(homework pass, candy).
7.
Explain to students that the United States and Canada share
the longest unprotected border in the world. We also share elements of a common
history and culture, as well as climate, natural resources, physical geography,
and environmental problems. Inform students that our environmental health unit
will deal with one of these common issues.
8.
Ask students to take out their Homework Canada Map answer sheets, and make sure each student has a
red pen. Have students mark their homework sheets as you read the answers.
Collect the marked homework sheets. Homework counts for 15% of the students’
grade for this unit. For each correct answer on this homework exercise,
students receive one Homework Point.
The maximum points possible for this exercise: 84.
Homework: Study for Canada Map Quiz to be given on Day Four.
Description: Students are
introduced to the acid rain problem using a problem-based learning scenario Killing Killer Rain. This scenario is a fictional account of a 7th
grade teacher who listens to the stories her students tell about what happened
to them during the “Great Power Blackout” during the summer of 2003. Class discussion raises many questions
about power generation in Canada and the United States. Students read the scenario, discuss the
scenario, and work in groups to generate specific questions about acid
rain.
Objectives: To engage students in active learning and problem solving
through a problem based learning scenario.
Time
allotted: One 45-minute
session
Materials:
·
One copy of Handout #3 Killing
Killer Rain for each student
·
Board and chalk or markers
3. Distribute the Killing the Killer Rain scenario (Handout #3). Inform students that this scenario is based on a real situation. Explain that the situation is one that many of them experienced themselves. Ask students if they remember their own experiences during the power outage that struck the Northeast U.S. in August, 2003.
Homework: Study for Canada Map Quiz (scheduled for next class period)
Day Four: The Situation and the Task
Description: Students are presented with a situation and task that will
direct their research on acid rain.
They brainstorm a list of questions that will help them make informed recommendations
about whether new coal-burning power plants should be built and whether
anti-pollution laws should be relaxed for older power plants.
Objectives: Students will demonstrate their
understanding of Canadian geography through a quiz. Students will brainstorm questions about the scenario, the
situation, and the task.
Materials:
·
One answer key Canada
Map Quiz (for teacher)
·
One copy of Handout # 4 Canada
Map Quiz for each student.
·
One copy of Handout # 5 Killer
Rain Assignment for each student
Activities
1. Students take
a 10-15 minute Canada Map Quiz
(Handout #4) testing their knowledge of Canada’s geography. Collect quiz. The quiz is out of 33 points, and students
receive a percentage grade. Quizzes are 20% of the unit grade.
2. Hand out one
copy of Handout #5 Killer Rain Assignment
to each student. Have one student read
out loud “The Situation” and another read out loud “Your Task” at the bottom of
the handout.
3. Remind
students that they will be working in groups and tell them that they will be
given 5 points toward their daily participation grade for each day they
contribute to their group or class discussions. The participation grade is 15%
of the unit grade. Monitor each group’s
progress.
4. Ask each of
the small groups to use a marker and their large pads of paper to generate a
list of questions, required information, and experts who might help the class
handle the task they have been presented.
Prompt the groups by asking what information they need to know about
coal-burning power plants and acid rain in order to make their recommendation
to the government. Encourage them to address the questions: Who? What? When? Where? How? and Why? The groups should be given about 10
minutes to complete this exercise. Notes to Teacher: This works best if each group identifies one member to take
notes and write down the questions. Inform students that they may choose a
single spokesperson for their groups, or they may divide the report among group
members.
5. Give groups 5
minutes to plan how they will present their questions.
6. Have each
group tape or post its large paper on the board and present its ideas. As they
work, record their questions on another part of the board—these should be
classified under the appropriate headings:
a. Sources,
Geography and Geology
b. Potential
Solutions
c. Environmental
Impact
d. Economics
e. Politics
f.
Health
7. Once all of
the groups have presented, discuss the most popular questions. Be sure to probe
why particular questions are important.
Homework: Students are to use the Internet or magazines
and newspapers at home or in the library to search for a recent news article
dealing with acid rain. They will write a one- to two-paragraph summary of the
article to hand in. “Recent” could be anything from the last two calendar
years. The summary should include the publication name, the title of the
article, the date, and the author. An attached copy of the article is useful,
but not required. A copy of the article
is not a substitute for the one
paragraph summary. This homework
activity is worth 30 homework points for this unit.
Day Five:
Identify the Problem and Begin Research
Description: Students organize their groups to begin researching both the
questions that they generated in the previous class and the questions on their Killer Rain Group Questions sheets. They
are provided with a list of suggested sources and information on the citation
formats that they should use for their research.
Objectives: Raise students’ awareness about
environmental health issues that affect their lives. Encourage and sharpen basic research skills such as locating
sources, taking notes, and citing sources.
Help students analyze information for authenticity and relevancy. Develop skills for collaborative learning,
interpersonal communication, and organization through group work. Teach students how information can be used
to solve a problem. Encourage student
participation in and understanding of current events, public debate, civics,
and advocacy approaches.
Materials:
·
One copy of Handout #6 Killer
Rain Group Questions for each student
·
One copy of Handout #7 Sources
of Information about Acid Rain for each student
·
One copy of Handout #8 Citation
Formats for each student
·
At least 10 note cards for each student (or have students
bring these to class)
·
Access to computer room with printer (and paper) and to the
library
Activities:
1. Students break
into their groups. Remind students that
their ultimate task is to advise U.S. and Canadian officials about whether to
build new coal-burning power plants and whether to ease anti-pollution
requirements for older plants.
2. Direct
students to look at the third paragraph on the Killer Rain Assignment sheet (Handout #5) and follow along as you
read the instructions. Read the rest of the assignment sheet to students and
answer student questions about the assignment.
3. Note to Teacher:
Be particularly clear about three matters:
§
Students in each group are responsible for dividing
responsibilities within the group. That
is, each student within the group should tackle specific questions on the
group’s list. However, group members are free to share sources of information
with other members in order to help the whole group.
§
Each student must hand in a 1-2 page typewritten summary
(report) addressing the questions he or she answered for the group. Although
students would be wise to use these reports to help them prepare for their oral
presentations, they should not read directly from their written reports.
§
Note cards are required to record information; students must
document their sources. (See Handout #5 for proper citation formats.)
4. Hand each
student a copy of Handout # 6 Group
Questions, Handout #7 Sources of Information about Acid Rain, and
Handout #8 Citations Formats.
5. Tell students
that they will have the remainder of Day Five class time and the next two class
periods to work individually and with their groups to research their
topic. They should use the questions
generated in the previous class and the questions on the Group Questions sheets to organize their research.
6. Students
should use Internet sources in the computer lab and print sources in the
library. Be available to assist
students in their searches for information and the writing of their summaries. Be certain to check that students are
preparing note cards using the required citation formats.
Homework: Continue researching and writing note cards with citations.
Day Six: Continue Research
Activities:
Homework: Continue researching, writing note cards, and preparing to
report the results of their research.
Day Seven: Continue Research
and Organize to Prepare for Group Oral Reports
Activities:
Homework: Continue researching and preparing for Killer Rain reports.
Days Eight, Nine and
Ten (depending on
class size): Group Reports
Description: Groups present the results of their research and their
recommendations to their classmates.
Objectives: Raise students’ awareness about environmental health issues
that affect their lives. Encourage
student participation in and understanding of current events, public debate,
civics, and advocacy approaches.
Encourage student participation in and understanding of current events,
public debate, civics, and advocacy approaches. Promote public speaking skills through class presentations on
group findings and recommendations.
Materials:
·
Chalk, blackboard for students to use during their
presentations.
·
One copy of Handout #9 Killer
Rain Summary Report Assessment for each student
·
One copy of Handout #10a or #10b Write a Letter! for each student
Activities:
1. Give all
groups an additional 10 minutes to organize their information in preparation
for their reports to the class. Remind
them that their presentation should include: their findings about acid rain and
their recommendation for whether the U.S. or Canada should build new coal-burning
power plants and/or ease anti-pollution requirements for older plants.
2. Give each group 10 minutes to present its findings about acid rain and its sources to the class. Each group should also recommend whether the U.S. or Canada should build new coal-burning power plants and whether to ease anti-pollution requirements for older plants. Depending on the size of the class, the presentations should take 2-3 class periods.
3. At the end of
each presentation, collect individual student summaries, citations, and note
cards.
Note to teacher:
Use the Handout #9 Killer Rain
Summary Report Assessment to score each student’s individual report as they
present, and then use the same sheet to grade the written part of the project.
It is strongly recommended that you complete the grade sheets for each student
as soon as possible, preferably the day of a student’s presentation. This will
enhance your ability to remember and respond to each student’s presentation; it
will also make your grading management task far easier later.
4. After all
groups have presented their reports, discuss the class’s efforts and what it
discovered about acid rain and its sources. Prompt students with questions such
as:
a. What was the
most interesting information learned from either your research or that of your
classmates?
b. Do you believe
that acid rain is a problem society has to deal with? How many don’t? Why or
why not?
c. Did anything
make you mad about the issue of acid rain? If so, why? Ask at what point during
this project they thought to themselves, “That’s not right” or “That’s
unfair”?)
d. Can average
citizens and middle school students help solve a problem such as this? How?
Note to Teacher: Ideally, for questions “a” through
“c,” students will address acid rain’s effects on human health and the fact
that affected populations usually live far away from the sources of the
problem. Some might be angered by the fact that technological solutions to the
problem are available, yet they are not implemented because of costs. As for
question “d,” some students will offer concrete actions such as ways they
themselves can conserve energy to reduce emissions from coal burning power
plants, automobiles, or other sources.
Others may come up with the idea that we can vote for politicians who
will act on the issue, or that they can write to public officials expressing
their viewpoints. If students do not generate these latter approaches, prompt
them to do so, and discuss the role of elected officials and our
responsibilities as citizens. Emphasize that elected officials want to know
what their constituents think, and that all of our voices count. This will set
the stage for the final assignment of the unit, Write a Letter. Continue to
follow any news related to energy and environmental issues, particularly those
related to coal-burning power plants and acid rain.
5. Distribute the
Handout #10a or #10b Write a Letter!
homework assignment and explain that this will be the final segment of the Killing Killer Rain unit in Social
Studies. It is an opportunity for each student to use his/her knowledge to help
formulate a letter expressing his/her views to a public official about acid
rain and the government’s energy and environmental policies. If time permits, allow students to begin
this assignment during class.
Note to Teacher: There are two versions of the Write a Letter assignment (Handout #10a
and Handout #10b). In the Handout #10b
assignment, students read several articles
that address Clean Air Act, in addition to writing their letters. Version #10b is lengthier but offers more
political context and content.
Homework: Give students
two days to complete a first draft of the Write
a Letter assignment.
Day Eleven: Complete the Write a Letter assignment
Description: Students “peer review” letters written by their classmates. By doing so, they make suggestions for
potential revisions and have an opportunity to read about the acid rain problem
someone else’s perspective.
Objectives: Raise students’ awareness about environmental health issues
that affect their lives. Encourage
student participation in and understanding of current events, public debate,
civics, and advocacy approaches. Teach students how information can be used to
solve a problem. Encourage student
participation in and understanding of current events, public debate, civics,
and advocacy approaches. Promote
writing and public speaking skills through class presentations on group
findings and recommendations.
