Organization and Subject Matter
Overview with
Goals and Objectives
This unit is on the social justice issue of trash in the community. It is designed to be used in a fourth grade class, but could be adapted for use in any upper elementary school grade. There are many reasons why this topic is very important. Worldwide the problem of waste management is “piling up.” The issue of waste management isn’t a new one. Throughout the world’s history, societies have had waste and have had to develop solutions to that problem. At this time the problem of waste management has become astronomical. Not only are cities having difficulty finding sites for landfills, but natural resources are also becoming more limited. It is critical that students learn that many of the thing that they throw away could be reused or recycled. There are other issues that surround waste management. Disease can be spread through waste, and toxic waste is especially hazardous for humans to be around. It's far better to reduce the toxicity and amount of solid waste in the first place than to cope with it after it has been created. For that reason this unit will focus most of its attention on teaching the students strategies to help solve this problem before it becomes too big.
People throughout the world have the right to live in an area that is clean and free of trash and litter. Sites for landfills are becoming increasingly hard to find and communities are reluctant to facilitate one that is nearby where they live. All too often the people who have to live near landfill sites are those who aren’t able to afford to live anywhere else. Is it fair that these people are being forced to live in areas that are potentially hazardous to their health?
As part of this unit, I will educate my students about alternative ways of managing waste, including reducing the amount of trash generated, reusing resources that are still in good shape, and recycling items that can be made into new things. In the national standards for social studies, teachers are encouraged to have their students work towards developing a response to a current local economic issue, such as how to reduce the flow of trash into a rapidly filling landfill (7J). Fourth graders will be able to internalize this information and are at an age where they can develop life skills in relation to waste management that will make a difference not only in their lives, but also in the quality of the earth’s environment.
In this unit, students will be given the knowledge and skills necessary to make a difference in the area of waste management. By educating students about these alternative methods of waste disposal, they will become knowledgeable about their role in improving the environment, and how society can help to alleviate problems that we are currently dealing with today. As students become environmentally responsible citizens, they will work towards finding solutions to problems that are currently being examined.

“Individual
consumers can help alleviate
Durable
goods (tires, appliances, furniture) and nondurable goods (paper, certain
disposable products, clothing) account for several million tons of the solid
waste stream. Container and packaging waste is a significant component of the
nation’s waste stream as well. This material includes glass, aluminum,
plastics, steel and other metals, and paper and paperboard. Yard trimmings such
as grass clippings and tree limbs are also a substantial part of what we throw
away. In addition, many relatively small components of the national solid waste
stream add up to millions of tons. For example, one percent of the nation’s
waste stream can amount to about two million tons of trash each year.
Across the country, many individuals, communities, and businesses have
found creative ways to reduce and better manage their trash through a
coordinated mix of practices that includes source reduction. Simply put, source reduction is waste
prevention. It includes many actions
that reduce the overall amount or toxicity of waste created. Source reduction can conserve resources,
reduce pollution, and help cut waste disposal and handling costs (it avoids the
costs of recycling, composting, landfilling, and combustion).
Source reduction is a basic solution to the garbage glut: less waste
means less of a waste problem. Because
source reduction actually prevents the generation of waste in the first place,
it comes before other management options that deal with trash after it is already
generated. After source reduction,
recycling (and composting) are the preferred waste management options because
they reduce the amount of waste going to landfills and conserve resources.
Integrated waste
management refers to the complementary use of a variety of practices to safely
and effectively handle municipal solid waste. The following is EPA's preferred
hierarchy of approaches.

To best accommodate the learning activities, the classroom should be organized so that each child can easily see the chalkboard because many activities will involve brainstorming as a whole class. Ideally if there were a class meeting area or rug where the children could gather, then many of the activities would more easily be facilitated. There should be room for students to store their posters or advertisements as they work on them. There should be a literacy center where students will have time to access books about waste and recycling.
The following chart is an example of how this unit could be organized for a 4-week period. It lists all of the national and state standards and objectives that are being met through this unit, and it also displays the learning activities that would be completed each week. This unit is designed for use in a classroom where at least 1 ½ hours to 2 hours will be devoted to the content outlined in this chart.

Lesson Plan #1
Title of Lesson: Landfill Construction
Teacher: Rachel Knudsen
Date: Week 1, Day 2
Time Allotted: 2 hours the first day and 15 minutes of observation and journal writing on each of the days following.
Grade Level(s): 4th grade
Number of Learners:
28
Unit Theme: What can we do about trash in our community?
Standards Met: (see below)
Goal: Students will be able to apply knowledge of economic concepts in developing a response to a current local economic issue, such as how to reduce the flow of trash into a rapidly filling landfill (NCSS 7j). Students will be able to consider existing uses and propose and evaluate alternative uses of resources and land in home, school, community, the region, and beyond (NCSS 3k).
Objectives: Students will become aware of the environmental problem of litter. They will understand the significance that there is no “away,” and will become familiar with different methods of disposal. Students will understand the meanings of the terms “organic”, “biodegradable,” “renewable,” and “nonrenewable resource” and why each kind of waste should be handled in a particular way.
Material Needed:
plastic gloves for picking up litter
pictures of landfills
labels
pens and poster board
four large, clear-glass jars
soil
miscellaneous solid waste
crayons
masking tape
Motivation:
1. Collect litter on
the playground and around the school with the students
2. Return to the classroom. Discuss with the students: Where does all this waste go when we put it
in the trashcan? What happens to the
item you threw away? Where is away? What is a landfill? How might the material
that a piece of trash is made of determine how you should dispose of it? Record
the student’s responses on the board.
Procedures:
1. Introduce landfills by showing the students
pictures. Discuss issues revolving around
landfills. (Finding sites for landfills
is becoming increasingly difficult.
Runoff from landfills can pollute surface and ground water. It is expensive).
2. Ask students what they think that they can do
to help solve this problem.
3. Discuss what kinds of waste students generate and discuss ways to reduce each kind.
4.
Have students help list ways you can avoid disposing of some items in a
landfill (such as reducing the amount of waste, reusing items more than once,
and recycling). Write these ideas on a
poster board and display in the classroom throughout the duration of the
unit.
5. Choose one item that was found on the school
grounds. What is the item made of? Into which of the following four categories
of solid waste does the item fit?
a. organic/biodegradable (e.g. potato peels)
b. renewable resource/recyclable (e.g. newspaper)
c. nonrenewable resource/recyclable (e.g. aluminum cans)
d. nonrenewable resource/hard to recycle (e.g. plastic toothpaste tube)
6.
With crayons and masking tape, label each glass jar with one of the four
category headings.
7.
Fill each jar about half full with soil.
8.
Sort each miscellaneous solid waste item into its proper category. Put a small
sample of each into the jar with the corresponding label. Cover with soil.
Leave the lid off and place the jar on a shelf away from people and out of
direct sun.
9.
Predict what you think will happen to the solid waste in each jar. Record your
predictions.
10. Have students observe and chart what happens over three weeks. Discuss observation charts in class and have students reflect in their journals about the following topics:
Accommodations:
Students who have
limitations or who are second language learners could be allowed to make a
picture journal instead of a written journal.
The jars that are used to contain the mini-landfills need to be stored
in locations that are safe and out of reach of the students. Children shouldn’t be allowed to handle the
jars or the contents of the jars without adult supervision.
Closure:
1. After the 2-3 week period is over, discuss
with the students: What happened to the
items made of organic and renewable resources?
What happened to the items made of nonrenewable resources? How did what happened compare with your
predictions? What comparisons can you
make between your mini-landfill and a real landfill?
Assessment/Evaluation:
1. Student’s understanding will be assessed through
their journal entry responses to the assigned topics given in class.
2. The observation tables that the students fill
out will demonstrate their participation in class and will show any
misconceptions that they may have in relation to the landfills so that these
misconceptions can be addressed and corrected.
Extension:
1. Students who
wish to further explore the topic of landfills may do so by creating posters
about littering and recycling. They can
then share their posters with the school by posting them in the lunchroom where
students will have the opportunity to dispose of their waste in a more
earth-friendly way.

Unit Theme: What can we do about trash in our community?
Standard(s) Met: See Below
Goal: Students will be able to apply knowledge of economic concepts in developing a response to a current local economic issue, such as how to reduce the flow of trash into a rapidly filling landfill (NCSS 7j). Students will be able to consider existing uses and propose and evaluate alternative uses of resources and land in home, school, community, the region, and beyond (NCSS 3k).
Objective: Students will participate in
activities that promote good citizenship (Standard 5). Students will demonstrate basic citizenship skills (Standard 5, Objective 1).
Students will identify
ways to meet community needs (Standard 5, Objective 2).
Materials Needed:
14 pieces of lined
paper
14 enveloped
14 stamps
pencils
crayons
chart paper
Dear World—How
Children…
addresses of elected
officials
Motivation:
1. Read the students
a selection from the book Dear World—How Children… and point out the
components of a well-written letter.
Procedures:
1. Talk to students
about ways that they can make a difference in the world. Discuss different ways that they can make changes
in their community, from the time that they are children until they are very
old. Make sure that students understand
that they have a voice that needs to be heard.
2. Talk about making
changes in their community through writing letters. Talk about the importance of being an active
citizen and that this shows good citizenship.
3. Explain to
students that they are going to write letters to an elected official of their
choice to persuade them to encourage recycling in their community.
4. Help students to
brainstorm ideas for their letters and write these ideas on chart paper.
5. Write a basic
outline on the board for the body of the letter.
6. Have the students
work in pairs to write their letters.
7. Have each
partnership switch letters with another partnership so that they can proofread
their letters and offer any suggestions that they can.
8. Have volunteers
share their letters with the class.
Accommodations:
Second-language learners could be paired with stronger English speakers so that they can help write their letters. If it is possible to find a government official who speaks their language, then they could write to them in their first language.
Closure:
1. Put addresses of
elected officials on the overhead and have students copy these addresses onto
envelopes. These are some addresses that the students could write to (federal
government only):
Honorable (name of
representative) President
(name)

senator)
Senate Office
Building
Washington, D.C.
20510
2. Put postage stamps on each envelope and mail
them.
Assessment/Evaluation:
1. While the pairs are working on composing their letters, the teacher will walk around and observe how well they are working together. Some things to look for are:
2. Teachers will look at each letter before the envelope is sealed and sent. Students will be assessed on their ability to write their letters in the format assigned. They should use correct punctuation and be able to formulate their ideas and arguments in a logical and organized way.
Extension:
For an extension students can write follow-up letters to the official that they wrote to before. They could even choose another individual or group to write to.

Teacher: Rachel Knudsen
Date: Week 1, Day 4
Time Allotted:
Grade Level: 4

Standard(s) Met: (See Below)
Goal: Students will be able to apply knowledge of

Materials Needed:
Trash by: Charlotte Wilcox
pictures of litter in public places
board
markers
poster board
Motivation:
1. Read the book Trash to the class.
2. Ask the students: Why do people litter?
Procedures:
1. Have the class brainstorm different reasons why people would litter and write these on the board. Some possible reasons why people might litter are:
• They are on property which doesn’t belong to them (because they feel no sense of responsibility for its upkeep).
• They are on property which is regularly cleaned up (because they know someone will clean up after them)
• They are on property where litter has already accumulated (because they think their little bit of litter won’t make any difference)
• Laziness: when people don’t go the few steps out of their way to use a public rubbish container, or when they don’t take the trouble to clean up a spillage from an overloaded refuse container, or don’t bother to containerize loading and unloading debris as it accumulates.
• Carelessness: when people throw litter at rubbish bins instead of placing it within them or don’t secure lids on refuse containers properly, or only partially cover loads, allowing loose materials to fall off and litter the roads.
• Lack of Awareness: when people thoughtlessly drop litter without really being aware that they are contributing significantly to a pollution problem.
• Compulsion: when people feel they must get rid of wrappers, containers and other items the instant these have served their purpose and, if there are no rubbish bins nearby, will drop these materials on the ground.
• Peer Influence: when people adopt the littering habits of the people they associate with.
• Apathy: when people accept litter as a part of life.
• Lack of Responsibility: when people rationalize that as long as other people are employed to clean up public or other property, there is nothing wrong in littering them.
• Lack of Law Enforcement: when people litter without fear of being caught or rebuked because the litter laws aren’t enforced regularly and people are reluctant to show or mention their disapproval to those they see littering.
• Lack of Education: when people have not been made conscious of the bad effects of litter and how they, as individuals, contribute to aesthetic, social, economic and hygiene problems it causes.
2. Share any ideas from the list that the students failed to mention.
3. Help students to look at the reasons why people litter to see which reasons could be eliminated. For example:
Education: getting the facts about litter across to the people who are littering, showing them that this habit is not socially acceptable.
Equipment: providing the facilities to keep an area clean because people tend to litter less in places which are tidy. Equipment includes bins to contain rubbish and brooms to sweep it up.
Example: applying positive peer pressure, setting a trend not to litter.
Encourage: rewarding people for disposing of their rubbish correctly.
Effective Laws: rules which define what unacceptable behavior is. Penalties for breaking these rules should be clearly set out.
Enforcement: making sure people obey the litter laws by punishing infringements.
4. If the students forgot to mention any of these reasons, then help the class by supplying them.
5. Show the students pictures of communities that have a lot of litter and talk about all of the reasons why littering is so harmful. Some of these reasons are:
• Pollution harms the environment and animals
• Litter is unsightly.
• Litter can pile up until it is a very large problem.
6. Tell students that they can make a difference in the litter problem by not littering and educating their friends and family about litter.
7. Have students help to write a class pledge to not litter anymore.
Accommodations:
A child who is blind and cannot see the pictures could have the pictures described to them in detail by their classmates.
Closure:
1. Have students sign the pledge saying that they aren’t going to litter.
2. Post this pledge in a conspicuous place for the duration of the unit.
Assessment/Evaluation:
1. Did the students contribute to class discussion?
2. Did each student sign the pledge? If not, were they able to provide a logical reason why they were unable to?
Extension:
Students could conduct a survey among their school or home to ask people if they litter. If they do, then they could ask them what their reasons were to see if they are the same as the ones addressed in class.

Materials Needed:
The Throwaway Generation by: Jill C. Wheeler
journals
28 Venn diagram templates
Motivation:
1. Read pages 19-25 from the book The Throwaway Generation to the class. These pages contain stories about 2 families—one from 1890 and one from 1990. It illustrates the differences in their lifestyles.
Procedures:
1. Talk about the book and have the students identify ways that these two times were so different with regards to the types of lives that they lived, the waste that they created, and how they dealt with their waste. How does garbage today differ from garbage of the past?
2. Have each student make a Venn diagram in which they compare and contrast the lifestyles of the 1890s with today.
3. Have students share some of their ideas with the class, and complete a diagram as a class on the chalkboard.
4. Draw a second Venn Diagram on the board. Label one side 2003 and the other side 2103.
5. Ask students to predict what kinds of lifestyles they think that people might have in the future. Ask them to reflect upon ideas such as:
Accommodations:
Students who are second-language learners may complete their Venn diagrams in their native language.
Closure:
1. Have students write a reflection in their journals about how they think the world will look like in 100 years.
2. As part of their reflection, make sure that students reflect upon whether or not they would like to live in the future, and what things they think that they can do today that will help to make the future a better place for coming generations.
Assessment/Evaluation:
1. Students will be assessed through their completion of Venn diagrams. Some things to consider are:
2. Students will also be assessed through their reflective journals. Their journals should contain the following:
Extension:
Students can make a time capsule containing items that they think best represent the type of lives that they have. The capsule would be opened in the year 2103.
Teacher Reflection:
In this unit students will be assessed through a variety of ways. This will help the teacher to evaluate the lessons and to see how they could be changed or adapted to increase student understanding. One of the main ways that students can assess student performance is through their journal entries. This is an excellent way for students to express their understanding and to make personal connections to the information that they are learning.
Another form of assessment used in this unit is through their projects and assignments that they complete. Participation is very important to the functioning of the unit, and so this is looked at as part of their assessment. Overall, students will be assessed upon how well they are learning the content knowledge and making connections to it with their personal life. Although this seems like it would be hard to asses, through journal writing and assignments, the students’ attitudes towards waste in the community will become evident. Here are some examples of modes of assessment used in the lesson plans:
1. Student’s understanding will be assessed
through their journal entry responses to the assigned topics given in
class.
2. The
observation tables that the students fill out will demonstrate their
participation in class and will show any misconceptions that they may have in
relation to the landfills so that these misconceptions can be addressed and
corrected.
3. While the pairs are working on composing their letters, the teacher will walk around and observe how well they are working together. Some things to look for are:
4. Teachers will look at each letter before the envelope is sealed and sent. Students will be assessed on their ability to write their letters in the format assigned. They should use correct punctuation and be able to formulate their ideas and arguments in a logical and organized way.
5. Did the students contribute to class discussion?
6. Did each student sign the pledge? If not, were they able to provide a logical reason why they were unable to?
7. Students will be assessed through their completion of Venn diagrams. Some things to consider are:
