Earth Day Activities: Environmental Uses of Phone Books

Posted by David Wetzel

Earth Day and Phone Book Activities

Earth Day and Phone Book Activities

Ever wonder what to do with all those old phone books?

Earth Day is coming and a good earth day activity is to develop creative uses for these phone books, beyond just recycling or throwing them in the garbage.

Phone books have a myriad of uses such as shredding the pages for use as packing material, compost materials, and booster seats.

Phone Book Facts

Despite the increase of Internet based telephone number directories, the production of phone books is increasing.

Here are some facts to get you thinking about how important it is to recycle or reuse your phone books.

  • On average, over 600,000 tons of phone books end up in landfills every year.
  • There are enough phone books created each year to measure 106,700 miles when lined up end to end. This means they would circle around the earth about 4.28 times!
  • About 80 percent of all U.S. paper mills use some recycled material in their manufacturing service. It is estimated that about 200 mills use ONLY recycled material.
  • There are more than 7,000 different titles of yellow pages.
  • 540 million telephone directories are distributed each year.

Earth Day Activities

Now that you see the current phone book dilemma, a good earth day activity is to find creative uses for all these unwanted phone books.

If just 500 phone books can be kept out of a land fill we could save between 17 and 31 trees, 7,000 gallons of water, 463 gallons of oil, 587 pounds of air pollution, 3.06 cubic yards of landfill space and 4,077 kilowatt hours of energy according to the American Forest & Paper Association.

Example Activities include:

  • Earthworm Bedding - shred the white pages and combine them with dirt, which enriches the soil as the pages decompose to support the earthworm habitat. Do not use the yellow pages, because of the chemicals.
  • Mulch - tear the pages out a phone book and lay them about 6 - 8 pages thick on top of the soil in a flower garden or among shrubs. Then cover the pages with a thin layer mulch. The pages will act as shield to prevent grass from growing through the mulch. Also the phone book pages will decompose and enrich the soil over time.
  • Booster Seat - use fabric to cover phone books, sealing the seams with fabric glue or needle and thread. This keeps the phone books from sliding around as kids wiggle around on them.
  • Packing Material - shred phone book pages for use in packaging instead of using packing peanuts. Shredded phone book pages are biodegradable and packing peanuts are not.

Your Turn - Share your ideas for additional uses of these relics of the past.

Science and Math Integration

Science and Math Integration

The Zerofootprint Kid’s Calculator is designed to help kids measure their life style’s impact on the planet.

Science and math measurements and calculations are made concerning carbon, land, water, and trees.

Environment Lessons

The website provides links to many lessons that integrate math science, examples include:

Impact on the environment through the use of cars, buses, trucks, planes, and more.

  • How Gasoline Works
  • Pollution Prevention
  • Green Cars

Impact on the environment based on what kids eat.

  • Bio Foods
  • Filter It Down - Water
  • Food Web

Impact on the environment of what kids use for example:

  • A Day Without Energy
  • Alternative Sources of Energy
  • Energy Alternatives

Impact on the environment of what kids throw away.

  • Enviroinfo: Recycling
  • Enviroinfo: Wastes
  • Garbologists Audits

Along with environmental lessons to teachers and home school parents.

  • Audit of Household Waste
  • Clean Air
  • Home Chemicals

Greenhouse Effect Investigation

Greenhouse Effect

Greenhouse Effect

Greenhouse effect is the a current science event that discussed widely at all levels of education and beyond. Often students have a basic knowledge of the greenhouse effect; however, many just nod their heads and pretend they know and understand.

I have developed a simply experiment that gives students hands-on, minds-on experience with how the greenhouse effect works.

Greenhouse Experiment

Materials: 2 Thermometers and 1 Large Seal-able Plastic Bag

Procedures:

  1. Place one thermometer in the plastic bag and seal the bag.
  2. Record the beginning air temperature in the bag.
  3. Place the plastic bag in direct sunlight.
  4. Place the second thermometer next to the bag.
  5. Record the temperature of the second thermometer.
  6. Wait 15 minutes and record the temperature on both thermometers.
  7. Wait 15 more minutes and record the temperatures again.

Questions for Students:

  1. What observations did they make?
  2. What was the role of the plastic bag in this experiment?
  3. What did the thermometer inside the plastic bag measure?
  4. What was the cause of the temperature increase in the plastic bag?
  5. What was the effect of the temperature increase in the plastic bag?
  6. What could they do to lower the temperature of the air inside the plastic bag?
  7. How can they compare the effects of caused by the temperature increase inside the plastic bag, with the greenhouse effect the earth is undergoing now?
  8. Other questions will develop as the discussion continues.
