An Educator's Reference Desk Lesson Plan
Submitted by: Therese Lloyd
School or Affiliation: Holy Rosary School, Idaho Falls, ID
Endorsed by: These lesson plans are the result of the work of the
teachers who have attended the Columbia Education Center's Summer Workshop.
CEC is a consortium of teachers from 14 western states dedicated to improving
the quality of education in the rural, western, United States, and
particularly the quality of math and science Education. CEC uses Big Sky
Telegraph as the hub of their telecommunications network that allows the
participating teachers to stay in contact with their trainers and peers that
they have met at the Workshops.
Date: May 1994
Grade Level(s): 5, 6
Subject(s):
- Interdisciplinary
- Science
- Mathematics
Overview: This lesson is designed to instill curiosity in the field of
solid waste science and to incite a response to improve the environment.
Purpose: The purpose of this lesson is to increase the awareness of the
elementary age student as to the need for solid waste management of the
environment and to give a sense of individual and community responsibility
and control over the world.
Objectives:
- Students will become aware of the types of materials
discarded into the environment.
- Students will identify and classify types of materials.
- Students will learn to predict and evaluate information.
- Students will work cooperatively in groups to process
information.
- Students will make decisions about further actions to be
taken concerning solid waste management in their environment.
Resources/Materials: Science and Children,
October l990, Volume 28, Number 2.
Activities
and Procedures:
- Have samples of the types of materials found in the solid
waste compositions of municipal landfills. Have students classify these
items into the following categories: paper, plastics, metal, glass
rubber/leather, yard waste, textiles, wood, food waste, miscellaneous.
- On l00 separate sheets of paper (used paper, of
course...remember the environment!!), label the categories from #1
above: Paper(34), Plastics(20), Metal(12), Yard Waste (10),
Rubber/Leather (6), Textiles (5), Wood (4), Miscellaneous (4), Food
Waste (3), Glass (2). This needs to be done before class, as the slips
of paper will be passed out to the students.
- Have students predict how many slips of paper will have the
names of each category. Write the predictions down individually and set
aside.
- Pass out the slips of papers to the students until all the
slips have been distributed.
- Write each category on the board. Each student reads a slip
of paper in turn while a class recorder marks the tally on the board.
- After all l00 slips have been recorded, have the students
compare their predictions with the actually tally.
- In small groups, discuss why different predictions worked or
didn't work. (In classes where percentage has been covered in math,
groups should explore the meaning of percentages applied to stacks of
papers of 50, 200, 500 and l000 sheets.)
- Have groups discuss the following questions:
a. Do the landfills in my town fit the national
percentages? What would be a practical way to find out?
b. What would you call a person who studies garbage? If you were
interested in working with the environment, what kind of jobs could you have?
c. What are some practical things you can do and as a class to
help protect your own immediate environment?
- Collect the garbage in your own home for three days. Compare
your percentages to the national numbers.
Tying It All Together: This is the beginning of any study on waste management. My class
analyzes garbage from the students' homes, the school cafeteria, the
neighborhood. We then take on projects to recycle and study the occupations
associated with environmental science.
