SWA Classroom Presentation Pre Lesson Plan Background for Teachers: The garbage from your home, apartment or townhome is collected by garbage trucks and taken to one of five transfer stations located throughout Palm Beach County. At the transfer station, garbage is transferred onto large semitrailer trucks. The large trucks can hold 4 truck loads of the smaller ones. (This procedure allows the smaller trucks more time on their route, it reduces traffic on the highway and saves fuel.) After the garbage is loaded into the larger trucks, it is driven to the Solid Waste Authority of Palm Beach County's Waste-to-Energy facility in West Palm Beach. The lightweight garbage is shredded and burned so that it can be used as a fuel source to generate electricity. The ashes leftover from the burning process are placed in a sanitary landfill along with any unburned garbage. (Sometimes people say that garbage goes into a dump; however, dumps are no longer used because they were not environmentally-friendly. State and federal regulations require landfills to have many environmental protective systems installed and maintained. In addition, the landfill is monitored on a regular basis.) The landfill is filling up rapidly because so many people throw away a lot of garbage. One way to stop the landfill from filling up is to recycle as much of the garbage as possible. Right now in Palm Beach County, the following items are recyclable at home:

Place in the recycling bin for containers: aluminum cans aluminum foil aluminum trays glass bottles & jars milk cartons juice cartons drink boxes all plastic containers Place in the recycling bin for paper: newspapers magazines catalogs phone books brown paper bags corrugated cardboard

Procedure:

1. Elicit responses from students as to what they threw in the garbage yesterday or this morning. Focus on items that could have been recycled. Explain that everyone throws away garbage everyday and altogether in Palm Beach County, we throw away approximately 2,500 tons (5,000,000 lbs.) of garbage in one day. This is enough to cover an entire football field 9 feet high. Consequently, the landfill is filling up quickly. Discuss how garbage is processed in Palm Beach County (refer to the background section) Discuss the importance of recycling. Tell the students that we can recycle many things at home. List the items that are accepted in Palm Beach County's recycling program (refer to enclosed pictures). Distribute the "Recycling Matters" activity sheet to each student. Allow students 15 minutes to complete the activity sheet. Review the answers to the activity sheet. Ask the students the following questions: 1) Name three reasons why recycling is good for the environment. Answer: Recycling saves natural resources, saves energy and saves landfill space. 2) Name three places you can recycle. Answer: Home, school and play (beaches and parks) 3) Do you think everyone recycles? Why or why not? 4) What would you say to someone who thinks recycling is not important and does not matter? Explain the homework assignment.

Recycling Matters

Some people believe that throwing away one thing in the garbage that could have been recycled does not matter. This is not true. If many people think this way, it could add up to a lot of garbage. That is why the landfill is filling up so quickly. This is harmful to the environment because land is being used for this purpose instead of providing homes for people, plants and animals. One way to stop the landfill from filling up as quickly is to recycle. When we recycle, the items are diverted from the landfill and are made into something new and useful instead. Therefore, recycling saves landfill space. In addition, recycling is important because it helps to save renewable and nonrenewable natural resources. For example, aluminum is made from a non-renewable resource called bauxite ore. Bauxite ore is said to be non-renewable because once the world's supply of this material is completely used up, there is no way to replenish it. Therefore, if we use up the all of the bauxite ore by making aluminum, we will be without this material forever. However, through recycling we conserve this natural resource by using existing aluminum products, rather than bauxite ore, to make more aluminum products. Another benefit of recycling is the conservation of energy. When products are manufactured from recycled material, it takes less energy to produce them. For instance, the energy saved by recycling one aluminum can is enough to run a television for three hours. Recycling also reduces pollution. Take the example of aluminum products. The bauxite ore used to make the aluminum products is most prevalent in Australia and is deep down in the earth. A great deal of pollution is created and a lot of energy is used when bauxite ore is mined. Recycling eliminates the need to mine for the bauxite ore; therefore, energy is saved and pollution is reduced. Recycling helps the environment in many ways. However, we can only see the benefits when people take an active part in recycling. So, remember to recycle wherever you are ­ at home, at school or at play. 1. What is the main idea of the article?

2. Underline the details in the article that support the main idea.

Review students' answers on the "Groovin' News" activity sheet. Homework: Ask the students to complete the rest of the "Groovin' News" activity sheet.

Background for Teachers:

Recycling is beneficial for the environment because it saves natural resources, conserves landfill space, and conserves energy. For example, aluminum is made from a non-renewable resource called bauxite ore. It is most prevalent in Australia. Much pollution is created and much energy is used when bauxite ore is mined and extracted from the earth. On the other hand, when aluminum is recycled, much energy is saved and bauxite ore, a precious natural resource, is saved. The Solid Waste Authority (SWA) of Palm Beach County has two recycling facilities. The Residential Materials Recycling Facility (RMRF) is for recyclables collected from residents. The Commercial Materials Recycling Facility (CMRF) is for recyclables collected from businesses. At both facilities, the recyclables are separated and prepared for markets. It is a labor-intensive process because many of the items are sorted by hand. For example, workers sort glass bottles by hand according to their color: green, clear or brown. After the items are sorted, they are shipped to companies that manufacture them into recycled products. Recycling programs vary from county to county and city to city. Palm Beach County's recycling program is contingent on several factors. The two main factors that are considered before adding new materials to the recycling program are: (1) processing logistics and (2) ability to secure a company or companies to purchase the material for a period of time. In Palm Beach County's recycling program, we can recycle many items at home, at school, at work, at parks and even beaches. Our program is among the top in the country. Through the active participation of residents, approximately 50% of the waste generated in the county is recycled. This percentage will continue to increase in the future because children today recycle out of habit, making it a part of their daily routine. That means the landfill will not fill up as quickly. In one year, recycling saved the equivalent of 2 acres of landfill space 74 feet high from being filled in Palm Beach County. Recycling matters!

1) 2) 3)

Procedure:

1. Review the importance of recycling. 2. Stress that recycling will help natural resources last longer and will therefore ensure they exist for future generations.

(continued)

Procedure Continued: 3. Explain that you going to give everyone two minutes to write down as many things as possible that can be recycled at home. As they list these items, the students should try to put them under the correct heading, "Yellow Recycling Bin" or "Blue Recycling Bin." At the end of the two minute time limit, call on some students to read their lists.

Blue RecyclingBin aluminum cans aluminum foil aluminum trays glass bottles & jars milk carton juice carton drink boxes all plastic containers Yellow Recycling Bin newspapers magazines catalogs phone books brown paper bags corrugated cardboard

4. Distribute the "Groovin' News" activity sheet and allow students time to complete the questions related to the bar graph and pie chart. 5. Review the students' answers. 6. Tell the students that scientists put information in the form of bar graphs and pie chars to help make it easier to read and compare data. 7. Explain to the students that in the next activity you want them to draw line graphs, bar graphs, and pie charts according to the details that you give them. Tell the students the following: (1.) Make a pie chart that shows 75% of the class recycles plastic containers, 20% recycles glass bottles, 5% recycles paper bags. (2.) Make a bar graph that shows 20 aluminum cans were recycled, 10 newspapers were recycled, 35 magazines were recycled. (3.) Make a line graph that shows 40 drink boxes were recycled, 25 juice cartons were recycled, 15 phone books were recycled. (4.) Make a pictograph that shows 3 aluminum cans were recycled, 7 newspapers were recycled, 2 paper bags were recycled. 8. Check students' graphs. 9. Distribute the "I Recycle" certificates. 10. Explain and assign the homework.
