real world patterns
 Explore patterns of US disposal and recycling
 Use tables and graphs to organize data
 Identify number patterns


Iceberg Model

leverage points of global issues


Lesson 1

Introductory Activity:
In small groups, answer these
questions about the items on
the next slide:
 Where does it go after it’s used?
 Can it be reused? If so, how?


Lesson 1

In small groups, answer these
questions about the items on
the next slide:
 Where does it go after it’s used?
 Can it be reused? If so, how?
Questions for the whole group:
 Is it OK for all these to be landfilled?
 How many plastic bottles do you use in a day?
 How many are used in the U.S. in 5 minutes?
2 million

Waste Not, Want Not

2. How many plastic bottles are used in 1 day
24 mil. bottles per hour x 24 hours = 576 mil. bottles
3. If 1/3 are recycled daily, how many are not?
2/3 x 576 = 384 mil. bottles OR 576 – (1/3 x 576)= 384 mil. bottles
4. 2 consequences of NOT recycling plastic bottles?
5. Create an equation to solve for number of bottles recycled
for any number of hours where B=Bottles & H=Hours
B = H x 24 mil. bottles


Waste Not, Want Not

6. Organize this data 5.5
into a line graph 4.6
7. Predict the number
of pounds per day
the average person
will discard in 2020
approx. 4.6 to 5.5 lbs


Waste Not, Want Not
8. All materials except plastics and
food scraps make up 76% of
our waste stream.
The % of plastics is the same
as the % of food scraps.
What % of our waste stream is
plastics?
(100% - 76%) / 2 = 12%
9. Recycling 4,050 20 oz. bottles
saves 1 cubic yard of landfill
space.
How many bottles need to be
recycled to save 50 cubic yards
of landfill space?
4,050 x 50 = 202,500

Waste Not, Want Not
Discussion Questions
Is it important to recycle as much as we can?
What are other ways to reduce the amount of waste we
produce?
Where is the closest landfill to your house? What factors
influence their location? Would you want one near you?
Will the amount of waste generated per person in the U.S.
continue to increase?
What kinds of materials are recyclable in your community?
What are barriers to recycling and ways to overcome them?
