ACTIVITY
2 LESSON 1: RENEWABLE OR NONRENEWABLE?
Discussion
1. Hold up the plastic container, aluminum can, steel can,
glass bottle, apple, paper, and leather belt.
2. Put up the “Natural Resources” overhead, and cover up the bot-
tom half (the pictures of the items). Tell the students that all
of these items are made from natural resources and that these
resources are either nonrenewable or renewable. Explain that
nonrenewable resources exist on Earth in limited amounts, e.g.,
fossil fuels (coal, oil, natural gas) and many minerals (e.g.,
iron, gold, and bauxite, the source of aluminum). Fossil fuels
are nonrenewable natural resources because they take millions
of years to form. Most minerals are also nonrenewable
resources. Explain that renewable resources are replaced natu-
rally or through human-assisted actions within a relatively short
amount of time, such as a human lifetime. For example, plants,
such as trees, can be replanted indefinitely.
3. Hold up the items, one at a time, and ask student volunteers
to classify them as made from a nonrenewable or renewable
resource. Uncover the rest of the overhead, and review the
items that were not discussed (i.e., gasoline, bike helmet,
etc.). Briefly explain how natural resources are taken from
the Earth and made into products.
4. Let students know that resources can also be classified
as perpetual resources. These are forms of naturally
recurring energy that are beyond human management,
e.g., sun, wind, falling water, tides. Put up the “Water
Cycle” overhead, and explain how the water cycle is an
example of a perpetual resource.
5. Introduce the concept of conservation. Ask students
whether there are ways that they can use fewer resources.
Share one way that students can conserve natural resources.
For example, by riding a bike to school instead of driving
in a car, students can conserve fuel, which comes from a
nonrenewable resource.
6. Show an overhead of the lesson rubric, and review the
expectations for this lesson.
Procedure
1. Divide the class into pairs. Give each pair of students the
following worksheets: “Everyday Items,” “Renewable
Resources,” “Nonrenewable Resources.” Also give them a
pair of scissors, and glue.
2. Instruct each pair to cut out the items and classify them
by gluing them into one of the two possible categories:
renewable or nonrenewable resources.
3. Review with the whole class which items they classified as
renewable or nonrenewable resources.
Wrap-Up
1. Ask students what they think will happen to
nonrenewable resources if we continue using them.
(They will be depleted.)
2. Ask students whether they think renewable resources are
always available forever. Pass out one sheet of newspaper
to each student, and have them roll it up to represent a
tree. Put all of the “trees” together at the front of the class
to represent a forest. Ask the students what would happen
if they needed to cut down ten trees a year to provide
enough paper for their school but only five trees were
replanted each year (the natural resource will be depleted).
3. Ask the students to turn to a partner to brainstorm
some ways that they can conserve nonrenewable and
renewable resources. (Use less. Use renewable resources
instead, e.g., a paper bag in place of a plastic bag.
Reuse bags and recycle them.)
4. Pass out the “Renewable or Nonrenewable” worksheet,
assign students to name one item from each of the four
categories (fossil fuels, minerals, plants and animals) and
explain how they can conserve the natural resources.
Final Assessment Idea
Have students identify ten items in the classroom, writing
the natural resource used to produce the item and whether
the resource is renewable or nonrenewable.
