Taking Action to Reduce Trash!
Laura Montague
Project Overview
Too quickly, the trash produced in modern civilization is “out of sight, out of mind”. As
society encourages production and use of the products of today, our trash piles are adding
up and causing issues of global proportion across the world. On average, a typical United
States citizen throws away the equivalent of their body weight in trash each month
(Hoornweg, Bhada-Tata, & Kennedy, 2013). When considering this fact in parallel to the
rise of the global population, it is questionable where exactly all of the trash is going and
how our over-use is manifesting into the environment and global community. Issues such
as the Texas-size patch of plastic in the Pacific and Atlantic Ocean (Lovett, 2010), and
the natural resources burned in the production of our trash, are only a few of the global
issues that surround our trash production and disposal. This four-week project will offer
students experiences to inquire into our production and disposal of trash, as they
collaborate with the global community to enrich their understandings and urgency to
invoke change. Upon conclusion of the project, students will have a variety of enduring
understandings surrounding this topic as well as have participated in the creation of a
Reducing Trash campaign with technology tools.

endangered when discussing animal preservation).
ICT Integration
Being a twenty-first century project, students will utilize technology tools throughout the
project to foster their understanding and sharing of learning. Throughout this projects
students are expected to…
utilize LessonPath.com to access learning resources including articles, videos,
and interactive activities to develop a foundational knowledge of waste
overproduction and disposal.
research data surrounding measurements of waste disposal within the United
States and across the world.
collaborate with students across the globe with epals.com to discuss waste
production and disposal in varying parts of the world.
collaborate with students in a different country to brainstorm solutions to the
waste disposal issue on a local and global level.

Proposed Calendar of Activities and Exchanges.
Week
Phase of Inquiry Cycle
Description of Activities and Exchanges
1
Tuning In
Introduction to the global
issue of waste disposal.
Students will begin estimating and measuring the
trash produced in-class each day. A discussion
surrounding what products contribute to the class’
production of trash the most begin and students
Students will work independently, in pairs, or in
small groups to navigate and negotiate meaning
from a pre-made learning playlist from the
website lessonpaths.com. Here, students gain
access to resources including articles, videos, and
interactive activities to develop a foundational
knowledge of the responsible waste production
and disposal.
Class will create a “Y” chart to determine what
they “think they know” and what they “want to
know”. Here, students determine what they find
interesting about the topic and determine which
direction each student will take to learn more
about this global issue based on their personal
inquiries.
lOMoARcPSD| 40342981
1
Finding Out
Students explore resources
to negotiate meanings
surrounding their personal
inquiries.
Students work independently, in pairs, or in small
groups to determine which resources will help
them learn more about the direction they are
taking with their inquiries. Teacher assists students
in finding and accessing resources to meet their
needs as inquirers.
For example - Students may inquire into how the
United States compares to other countries in the
world in terms of waste production. Other students
may inquire into how citizens of other regions
dispose of their waste. Teachers may prompt
students to post on a blog, epals.com, or
purposefully arrange a pen pal from targeted
regions to discuss waste production and disposal
practices.
2
Sorting Out
Students collaborate among
each other to determine
relevant information from
irrelevant information.
Class convenes to share information students have
gained surrounding their inquiries. Students take
turns to share the questions they are exploring
about the global issue alongside the information
they gained from their research. As students share,
the teacher prompts students to determine which
information is the most relevant to targeted
inquiries of the students. If students are
collaborating with people from other parts of the
globe, it is recommended that this information is
documented on a classroom map to foster
geographical understandings and the determining
of possible relationships between findings. By the
end of the discussion, the class has create a
concise and explicit compilation of information
that pertains directly to student inquiries
established in the “Tuning In” phase.
lOMoARcPSD| 40342981
2
Going Further
Students establish a
platform and information to
be shared with the local
and/or global community.
Students then create their
presentation.
As students begin to explore their possibilities for
sharing their learning with the local and/or global
community, it is recommended that teacher expose
students to exemplars of student-made
presentations with technology tools to better
enable students to decide how they will share their
learning. Possibilities of technology tools for
utilization include Powtoon.com, BitStips.com,
photopeach.com, the Lego Movie Maker app, or
animoto.com.
Once the students decide how they will share their
information, they can work on iPads or in a
computer lab to create their presentation of the
relevant information established in the “Sorting
Out” phase.
3
Making Conclusions
Once students have created
and shared their
presentation made with their
technology tool, they
develop concise conclusions
Students share the presentations they created
using their technology tools with their class or the
global community through a blog or Skype.
Students then reflect on what they have learned
for their project and how it relates to the global
issue of irresponsible waste production and
disposal. Students must establish which audiences
would
about their learning and
how it relates to their world.
benefit from viewing their creation and learning
what they have learned. To do this, students may
choose to discuss with a collaborative group to
determine the best-fit audience and how their
learning relations to their own world and personal
actions.
lOMoARcPSD| 40342981
3
Taking Action
Students put their learning
to work by taking action in
in their own world to
contribute to the need for
responsible waste
production and disposal.
Now that students have determined enduring
understandings surrounding their inquiry project
and the inquiry projects of their classmates,
students take action as they see fit. Actions may
include; choosing to only eat from reusable
containers, kickstarting a school recycling or
composting program, writing letters to
government officials to urge stricter
environmental laws surrounding waste production
and disposal, creating a school garden to offset
carbon emissions from production and to make
use of compost, or participating in a “Zero-Waste
