Task 3a: Goods Analysis – Waste Audit
According to the Annenberg Foundation, the average American generates four pounds of
solid trash per day, for a grand total of 1,460 pounds per year. Americans are the number
one global trash offenders! Every day, we collectively dispose of approximately 200 million
tons of the stuff. Less than one-quarter of it is recycled, leaving the rest for landfills and
incinerators. Part of analyzing the Goods component of your ecological footprint is getting a
better idea of how much trash you generate.
In this task, you will be recording and collecting the amount of waste that you and your
family generates over a 24 hour period. Materials recorded should include all waste
including any items that may be recycled, composted, or reused in some way. Examples of
items to be recorded include mailed letters, junk mail, food wrappers, beverage containers,
other product packaging (e.g., shampoo bottles, deodorant containers, toothpaste tubes),
newspapers, aluminum foil, plastic and paper grocery bags, pizza boxes, toilet paper, the
roll from toilet paper…you get the idea. You will keep a running inventory of your solid
wastes throughout the day, with a final tally of the number of items recorded by the
beginning of the next class.
You will be required to also get the mass of all the waste that you record over the 24 hour
period. In order to do this, you must either bring in the waste in a bag for getting the mass
Some suggestions for gathering data…
- When you get home, take out the garbage in your home so that each garbage can and
recycling bin has nothing in them, so you can record the data for the entirety of the
period.
- When you are out of the house, have a bag to carry any excess waste that you might
have over the day.
- Have your data sheet on you so that you can record any waste over the day.
Part 1: Gathering Data
Use the chart on the next page or bring in waste for 24 hours to record the amount of waste
that you and your family produce.

Task 3b: Goods Analysis – Electricity Audit
We will continue to break down our eco footprint into the different components that make
it up. The past couple of days focused on waste; today we will be focusing on electricity. In
this audit, you will be looking at any appliances and electrical devices that are plugged into
a socket at your home (lamp, tv, phone charger, stereo, etc.) and seeing how much power
that it pulls from that socket. In order to do this, you need to do a careful inventory of what
is plugged in at your house. We will get initial practice with this for homework today.
For homework, fill in this chart below with 3 electrical devices that are plugged in at
your home. Try to do smaller ones that you can look at the back of. Try to find the power
ratings of the appliances. Here is a sample of the label that you can find on most appliances:
Part 1: Initial power ratings
We will try 3 sample appliances tonight, and focus on more later. Make sure to fill out all
you can; we will work on the calculations in class tomorrow.
Appliance Power rating Approximate number of hours on per day (if on
for half hour, write in 0.5 hour, not 30)
Number of appliances in house
Look for the wattage
on the label. This is
the power that the
appliance uses if
turned on for an hour.
In this case, if on for
an hour, this uses 2.15
kilowatts, or 2,150
watts.

You will continue this work tonight by recording ALL THINGS that are plugged in at your
house. THIS ALSO INCLUDES LIGHT FIXTURES!
If you cannot find the power ratings of everything, do not worry. There will be time to
research power ratings for difficult appliances in class. If you need more room, add
another sheet to the chart.

Task 3c: Mobility Analysis
How does your family get around? Do you walk, bike, take the bus, drive your own car, or
carpool with others? In this task you’ll analyze your family’s transportation habits and
create an alternative transportation plan for your family.
In this audit, you will record the amount of driving that your family does over a 2 day (48
hour) period. A major part of your eco footprint is the way that you and your family choose
to use transportation methods. We will be looking at how much gas is used in your family
on a daily, monthly, and yearly basis.
Part 1: Gathering Information at Home
Answer the following questions to help guide your data collection. If you need help, ask
your parent/guardian for this information.
1. How many cars are in your household?
2. What is the make/model and year (ie 2003 Honda CR-V) of the car(s)?
3. How many miles are on the odometer (total amount of miles driven in the car’s
lifetime) for the car(s)?
4. How many flights did your household take this year (if any)?
5. Where were those flights to (if applicable)?

Task 3d: Water Audit
By now you’ve become very familiar with auditing different aspects of your ecological footprint.
Today, we will be looking at the final aspect of your footprint; water usage. We often forget about the
amount of water that we use in a day, though it is one of our most precious resources. You will track
the amount of water used by your household over a 24 hour period. To do this, first brainstorm all
the places that you use water in your house. Write them below:
Water usage in your home brainstorm:
As you discuss the different places for water use, make sure to write in any that you did not think
about! You will be tracking this once you get home.

Task 3b: Goods Analysis – Electricity Audit
We will continue to break down our eco footprint into the different components that make
it up. The past couple of days focused on waste; today we will be focusing on electricity. In
this audit, you will be looking at any appliances and electrical devices that are plugged into
a socket at your home (lamp, tv, phone charger, stereo, etc.) and seeing how much power
that it pulls from that socket. In order to do this, you need to do a careful inventory of what
is plugged in at your house. We will get initial practice with this for homework today.
For homework, fill in this chart below with 3 electrical devices that are plugged in at
your home. Try to do smaller ones that you can look at the back of. Try to find the power
ratings of the appliances. Here is a sample of the label that you can find on most appliances:
Part 1: Initial power ratings
We will try 3 sample appliances tonight, and focus on more later. Make sure to fill out all
you can; we will work on the calculations in class tomorrow.
Appliance Power rating Approximate number of hours on per day (if on
for half hour, write in 0.5 hour, not 30)
Number of appliances in house
Look for the wattage
on the label. This is
the power that the
appliance uses if
turned on for an hour.
In this case, if on for
an hour, this uses 2.15
kilowatts, or 2,150
watts.

From the lecture/notes, calculate kilowatt-hours for the appliances you found for
homework. Make sure to show your work!

Part 2: Total Electrical Power Audit
Once I have checked off the calculations, fill in the first 3 rows with your initial findings.
You will continue this work tonight by recording ALL THINGS that are plugged in at your
house. THIS ALSO INCLUDES LIGHT FIXTURES!
If you cannot find the power ratings of everything, do not worry. There will be time to
research power ratings for difficult appliances in class. If you need more room, add
another sheet to the chart.

Task 3c: Mobility Analysis
How does your family get around? Do you walk, bike, take the bus, drive your own car, or
carpool with others? In this task you’ll analyze your family’s transportation habits and
create an alternative transportation plan for your family.
In this audit, you will record the amount of driving that your family does over a 2 day (48
hour) period. A major part of your eco footprint is the way that you and your family choose
to use transportation methods. We will be looking at how much gas is used in your family
on a daily, monthly, and yearly basis.
Part 1: Gathering Information at Home
Answer the following questions to help guide your data collection. If you need help, ask
your parent/guardian for this information.
1. How many cars are in your household?
2. What is the make/model and year (ie 2003 Honda CR-V) of the car(s)?
3. How many miles are on the odometer (total amount of miles driven in the car’s
lifetime) for the car(s)?
4. How many flights did your household take this year (if any)?
5. Where were those flights to (if applicable)?
Begin filling in the chart on the next page; you should be able to fill in the first rows

Part 2: Flights
You should have already gathered information on flights for the year from your
household. Use this information to fill in the audit information for other transportation
that you and/or your family has taken this year.
In class, use computers and google maps to find the distances for the flights that your
household takes. Fill in the chart below with the distances (keeping in mind ROUND
TRIPS).
Some information to help you:

Task 3d: Water Audit
By now you’ve become very familiar with auditing different aspects of your ecological footprint.
Today, we will be looking at the final aspect of your footprint; water usage. We often forget about the
amount of water that we use in a day, though it is one of our most precious resources. You will track
the amount of water used by your household over a 24 hour period. To do this, first brainstorm all
the places that you use water in your house. Write them below:
Water usage in your home brainstorm:
As you discuss the different places for water use, make sure to write in any that you did not think
about! You will be tracking this once you get home.
In the chart below, fill in the first part of each section (# of daily flushes, average length of shower,
showers per day, etc.). Your teacher will give you the average numbers for each section, so you
can calculate the total gallons used per day.
Make sure to be as accurate as possible with your estimates!
