Section 3: Background

Key Points will give you the main information you need to teach the activity.

  • Litter is trash, debris, and other items discarded in places they don’t belong, such as roadsides, waterways, or parks.
  • Litter is a widespread problem which is affecting habitats of all living things. Improperly discarded materials not only ruin the beauty of our community, but can be harmful to us as well.
  • Three ways to help with the litter problem is to reduce, reuse and recycle. Think first of reducing waste and if that’s not possible, try hard to reuse the waste item. The last option after reducing and reusing should be recycling.
  • The South Carolina Aquarium is leading the way to empower citizens to make a positive impact while generating scientifically useful data available to the general community and scientific community though its citizen science project, Litter-free Digital Journal.
  • The goal of the Litter-free Digital Journal is to promote collaborative solutions by removing and tracking litter, plastics specifically, from habitats throughout South Carolina. Students can clean up an environment and be part of the solution.

Detailed Information gives more in-depth background to increase your own knowledge, in case you want to expand upon the activity or you are asked detailed questions by students.

Litter is trash, debris, and other items discarded in places they don’t belong, such as roadsides, waterways, or parks. Deliberately throwing items on the ground or leaving items outside of a trash bin is littering. Sometimes it can be accidental, such as materials being blown out of a trash can or truck bed.

According to the 2009 KAB National Litter Survey Study, the most common roadside litter articles include tobacco products, unclassified trash, miscellaneous paper, packaging, miscellaneous plastic, and beverage containers. The study also found that the quantity of plastic litter observed has increased over the past 40 years. Plastic does not degrade or does so slowly with time. Also, being lightweight, plastics tend to be transported by wind and water to other locations, which adds to a growing marine debris issue (trash in the ocean).

Problems of litter include:

  • Physical harm or injury to people – Needles, blades, broken glass, cigarette butts causing fires, byproducts from drug packaging
  • Spread of disease – Can provide breeding ground for diseases that can be passed to animals that eat it
    • water can be collected on litter which harbor mosquitoes that carry several illnesses
    • toxic chemicals and disease causing microorganisms can leach, which can contaminate our water system
  • Aesthetics and quality of environment – Public spaces scattered with litter are typically less inviting. Studies show that once a space is littered, other people are more likely to litter there too. Small amounts of litter can initiate a downward spiral for a communal space, which can affect the overall community.
  • Economics – Direct costs of litter cleanup
    • Indirect costs, caused by the negative effects of litter in an environment. Litter in waterways and public areas can negatively affect tourism and property values, resulting in fewer jobs.
  • Polluted environments – Litter can be blown or washed into rivers and creeks that lead to the ocean, polluting the watershed and the ocean. The oceans are filled with huge amounts of consumer plastics, metals, rubber, textiles, paper, derelict fishing gear, and other discarded materials, making marine debris one of the biggest problems facing the oceans and waterways.
    • Cigarette butts and other trash contain toxic substances that contaminate soil and water
    • Reduced air quality due to smell and toxic vapor from trash
  • Harm to wildlife – Litter, plastic specifically, is often mistaken for food by animals, which can make them sick or die
    • When animals consume litter, it effects the whole food chain. When fish eat plastic in the ocean mistaking it for food, the plastic is passed to humans when the fish is consumed.
    • Animals can get tangled in litter, which can harm them physically or prevent them from finding or catching food

 Solutions to litter include citizen science, reducing and reusing waste as well as recycling when reducing and reusing is not an option.

Citizen Science
Defined by the Oxford Dictionary, citizen science is the collection and analysis of data relating to the natural world by members of the general public. Citizen science occurs when ordinary people help to conduct real scientific research. People can share and contribute to data monitoring and collection programs, usually as a volunteer. Participants have varying degrees of expertise. Modern technology makes citizen science accessible to anyone interested in participating, however, the success of the project depends on the creation of a well-devised monitoring program and participant dedication.

Many citizen-science projects have a national or local focus. Some projects are created by scientists, who need widespread data with the help of public observation. There are also projects community-based groups organized to generate ideas and involve scientists for advice and coordination. One of the oldest examples of citizen science in the National Audubon Society’s Christmas Bird Count, which began in 1900. From December 14-January 5, birder groups collect information about local bird populations, which can be used for conservation efforts.

The South Carolina Aquarium has a citizen science application and an anecdata website called the Litter-free Digital Journal for collecting trash data from the people of South Carolina. Community members are urged to collect trash from the environment and log the data on the app. Data is placed into categories and pictures can be downloaded as well as the location in South Carolina. These data is being used to change policy. Folly Beach and Mt. Pleasant, SC are two towns who have already had plastic bag bans put into effect. Aquarium staff have been a part of that change using the data from the app. It’s an exciting time to see all people be able to make an impact to better the environment. Get your students involved as well through this activity!

Reduce and Reuse
The most effective way to prevent litter is to not create it in the first place. Reducing and reusing materials prevents new products from being made and transported. Americans generate over 4 pounds of trash every day, which mostly gets sorted into landfills. These landfills create the second largest source of human-related methane emissions in the country. Reducing and reusing also saves energy, saves money, prevents pollution caused by making new products, and allows products to be used to their fullest purpose.

Approximate Time it takes for Garbage to Decompose in the Environment:
*This data is from The Educator’s Guide to Marine Debris from SC Sea Grant, DHEC, COSEE and NOAA. The decomposition rates may change over time due to more research. Go here for a printable poster http://www.scdhec.gov/HomeAndEnvironment/Docs/SC_MARINE_DEBRIS_POSTER.pdf

Garbage Item Decomposition Time
Glass Bottle Undetermined
Monofilament Fishing Line 600 years
Plastic Beverage Bottle 450 years
Disposable Diapers 450 years
Aluminum can 200 years
Foam plastic cup 50 years
Plastic bag 1-20 years
Waxed milk carton 3 months
Apple core 2 months
Newspaper 6 weeks
Paper towel 2-4 weeks

Plastic never fully biodegrades once it is in water. Instead, it breaks down into smaller and smaller pieces. Microplastics are pieces of plastic that are less than 5mm long. Macroplastics are pieces of plastic that are larger than 5 mm.

Ways to reduce and reuse:

  • Do not use single-use plastics, which include plastic bags, plastic water bottles, take-out containers, take-out cups, eating utensils and straws
  • Use reusable products instead, such as a reusable shopping bag, thermos or reusable water bottle, reusable food containers, a personal cup, reusable eating utensils and just don’t use a straw or use a stainless steel/reusable/paper straw
  • Buy products that use less packaging. Buying in bulk can also reduce packaging and save money
  • Borrow, rent, or share items used infrequently
  • Maintain and repair products, so they aren’t discarded frequently
  • Buy used things, which are often less expensive and just as good as new

Recycle
When materials can’t be reduced or reused, recycling is a great option. Recycling materials reduces the amount of waste sent to landfills. Natural resources are conserved by turning old products into new products, which prevents pollution by reducing the need to collect new raw materials. Recycling increases economic security by using a domestic source of resources, creating more jobs in manufacturing industries in the United States.

 What can be recycled?

Plastic

  • Water bottles
  • Soda bottles
  • Milk jugs
  • Liquid containers
  • Jars and tubs (yogurt, margarine tubs, etc.)
  • Detergent and all-purpose cleaner bottles
  • Soap and shampoo bottles
  • Plastic cups
  • Rigid plastic product packaging, such as clean rigid clamshell containers (Remove any plastic film or aluminum)

Approximately 300 million tons of plastic is produced globally each year and only 10 percent of it recycled. An estimated 7 million tons of plastic that is trashed ends up in the ocean each year, where it breaks down into microplastics. The smaller the pieces, the easier they are to be swallowed by fish. Plastics are derived from natural, organic materials such as cellulose, coal, natural gas, salt and crude oil.

What do the symbols mean on the bottom of plastic bottles and containers? These symbols were created by plastic manufacturers to help people identify the kind of plastic resin used to make the container. This can help you determine if the container can be accepted by your local recycling program. Plastics #1-7 can be recycled in Charleston County, however plastic bags cannot be included into mainstream recycling bins, but instead must be taken to a store. Check with your county to see which plastics can be recycled.

 Paper

  • Magazines
  • Newspapers
  • Office paper
  • Envelopes
  • Junk mail/envelopes
  • Greeting cards
  • Catalogs
  • Books/textbooks
  • Coupons
  • Posters
  • Sticky notes
  • Paper bags
  • Wrapping paper

Paperboard and cardboard

  • Corrugated cardboard boxes (flattened)
  • Soda/beverage boxes
  • Shoe boxes
  • Gift boxes
  • Clean food boxes (cereal boxes, microwave meals, boxes of rice, etc.)
  • Paper towel rolls
  • Paper egg cartons

Paper typically makes up a third of the trash produced each year in the United States. Recycled paper is used to make new paper products, which saves trees and other natural resources.

Glass

  • Jars and caps (labels can be left on containers)
  • Bottles and bottle caps (labels can be left on containers)

Glass can be recycled again and again and again. Making new glass from recycled glass is cheaper than using raw materials. Glass is made from a mixture of sand, lime and soda heated together, to form liquid glass. This liquid glass is made into sheets by cooling and flattening. To make objects like vases, craftsmen blow into a glob of liquid glass with the help of a long tube. Typically, at least a quarter of the glass discarded in the United States each year is recycled.

Aluminum and steel cans

  • Aluminum cans and caps/lids
  • Steel and tin cans
  • Empty aerosol (spray) cans
  • No foil or trays

Cans are made from aluminum and trace amounts of other metals, including magnesium, iron, and manganese. Aluminum is one of the only materials that can be recycled over and over again! There is no limit to the number of times you can recycle it, making it one of the most valuable recyclables.

Batteries

Look for in-store recycling bins or community collection events to dispose of batteries. According to the EPA, in 2014, about 258 million tons of municipal solid waste (MSW) was generated in the United States. Over 89 million tons of MSW were recycled and composted, equivalent to a 34.6 percent recycling rate.

Other: Plastic bags, ink cartridges, old phones, corks, etc.

There is some waste that can be recycled, but not through mainstream recycling. Materials in this category take more time and effort to be recycled. Lots of grocery stores have plastic bag recycling. Cell phone carriers and electronic stores typically recycle or even buy old phones and tablets. Ink cartridges can be recycled at office supply stores. Lots of health food stores recycle corks. Just looking up an alternative to throwing waste away can make a difference.

Composting
Compost is organic material, including food scrapes and yard waste, which can be added to soil to help plants grow. Making compost keeps these materials out of landfills where they take up space and release methane. The following can be composted:

  • Fruits and vegetables
  • Eggshells
  • Coffee grounds and filters
  • Tea bags
  • Nut shells
  • Shredded newspaper
  • Cardboard
  • Paper
  • Yard trimmings
  • Grass clippings
  • Houseplants
  • Hay and straw
  • Leaves
  • Sawdust
  • Wood chips
  • Cotton and Wool Rags
  • Dryer and vacuum cleaner lint
  • Hair and fur
  • Fireplace ashes

How to do Backyard Composting:

  • Select a dry, shady spot near a water source for your compost pile or bin.
  • Add brown and green materials as they are collected, making sure larger pieces are chopped or shredded.
  • Moisten dry materials as they are added.
  • Once your compost pile is established, mix grass clippings and green waste into the pile and bury fruit and vegetable waste under 10 inches of compost material.
  • When the material at the bottom is dark and rich in color, your compost is ready to use. This usually takes anywhere between two months to two years.

How to do Indoor Composting:

If you do not have space for an outdoor compost pile, you can compost materials indoors using a special type of bin, which you can buy at a local hardware store, gardening supplies store, or make yourself. A properly managed compost bin will not attract pests or rodents and will not smell bad. Your compost should be ready in two to five weeks.

Section 4: Procedures

  • Litter Data Sheet
  • Chart paper/white board and markers
  • Gloves
  • 2 Trash bags per group (1 color for trash and 1 color for recycling)
  • Recycle label
  • Paper
  • Color pencils
  • Smart phone or computer

Teacher preparation: Here are the instructions for how to use the Litter-free Digital Journal app and website in order to input your student’s data. Either and both data entries can be used depending on if you want to use your smart device or a computer. The website will allow for more options when looking at the data (graphing, lists, downloads,…). The app seems to work easiest for data entry.

To download the Litter-free Digital Journal app on your smart device:

  • Search for South Carolina Aquarium in your App store on your smart device
  • Open the SC Aquarium Citizen Science App in your App store and download it for free
  • Create an account with your email and a password
  • Click on the Litter-free Digital Journal
  • Add a picture to your profile and include information about yourself if desired
  • You are ready to input your student’s data!

To use the Litter-free Digital Journal anecdata website:

  • Go to: anecdata.org
  • Set up an account (or use the same information if you set up an account on your smart device)
  • You can use either the website or the app to input data.

Activity Procedure:

1. Begin a discussion about litter. Ask: What is litter? Trash that ends up in our habitat. What is a habitat? A home for living things. Do the animals put the trash in the habitat? How do you think the trash gets outside? Where does the litter go?

2. Encourage the students to talk about ways litter can affect a habitat. Have them think about ways they can help.

3. Explain to the students that they will be part of a citizen science experiment today to help clean up the habitat around their school! Breakdown citizen science to help the students understand what it means. Ask: What is a citizen? A member of a town, city, state, or community. Are we citizens? YES! We are members of our community in our town/city of _____. Ask: What is science? The study of nature and the way natural things act. So, to put it together, citizen science is the “study of the natural world done by members of the community.”

*Oxford definition of citizen science: collection and analysis of data relating to the natural world by members of the general public.

4. Invite the students to think about HOW MUCH litter they will find in their schoolyard habitat. Talk about what KINDS of litter they will find. Chart their ideas on chart paper or the board. Talk about how litter ends up outside of their school to help think about what KINDS of litter they may find (Cafeteria food wrappers, personal belongings left behind, litter blown into the school yard, paper from schoolwork).

5. Explain that while the class conducts an experiment finding out HOW MUCH (quantitative data) of certain KINDS of litter is on their schoolyard, scientists from the South Carolina Aquarium are conducting similar experiments and need help. You can explain that their data will be put into the computer and sent to scientists to analyze through a special Litter-Free Digital Journal app. The information is then used to make positive changes in the community. The information has been used to ban plastic bags in parts on Folly Beach and Mt. Pleasant, SC, and can be used to make more positive change. If desired, display pictures and graphs from the Litter-free Project through the Anecdata website (https://www.anecdata.org/projects/view/122/about ) to get the students excited.

6. Before you head outside, talk about what is considered TRASH and what is RECYCLABLE. Anything paper, most plastics, glass, or cans can be recycled. Food waste, snacks and lunch food left outside, will be put in the trash, however, could be composted. Personal belongings, such as jackets, hats, water bottles, lunchboxes, will go in the trash or the lost and found if salvageable. Trash, such as rope, wrappers, and straws will go into the trash bag. The recorder will record (tally) the types of litter found, with the help of the rest of the group members. Explain which bag is trash and which is recycling. You can put a recycling label on the recycle bag, if it helps the students. NOTE: The 4 categories are listed to begin a discussion about different waste. Even though most of the personal belongings and food waste will be trash, there are alternative ways to dispose of them to reduce and/or reuse.

7. Assign groups of 4 and roles to each student within the group:

  • Recorder: writes a tally mark each time litter is picked up and sorted
  • Materials: holds the trash bag and recycling bag with gloves on, helps sort litter
  • Litter Gatherer: picks up the litter and puts litter in the appropriate bag with gloves on, helps sort
  • Seeker: on the lookout for litter and decides where to look, helps sort

8. Provide a few minutes for each group to formulate their hypothesis on the Litter Data Sheet. They should discuss which litter group they think they will find the most of while collecting.

9. Teach them how to make tally-marks on the data sheet.

10. GO FOR IT!!! Collect litter on the schoolyard for 10-15 minutes or whatever time is allowed. Help the recorders put tally marks for each litter category. If manageable, take some pictures to upload with your data.

*Note- If classroom management is challenging outside, students can just pick up litter and put it into one bag. Sorting can be done in a more confined place together outside or inside, with gloves. Tally marks can then be done with more direct supervision. Every class is different.

11. Find a place to discard the litter and recycling and invite the students back inside to discuss their findings.

12. Ask each group to report what they found. Make a running tally on the chart paper/board. Remind the students that their findings are super important to finding solutions to litter and that you will put their findings into the computer for the South Carolina Aquarium Scientists to use.

13. Make a bar graph together as a class on the board using the class’s data.

14. Discuss their findings using these questions.

  • What was the most common litter found?
  • Why do you think it was the most common?
  • What can we do to help with the problem?
  • Why is it important to have a litter free schoolyard?

You can discuss how the litter affects the habitat of the plants and animals that live in the schoolyard. Animals could eat the trash and become sick. The trash could harm the ground making it hard for the plants to grow.

15. Lastly, talk about solutions to the litter that was found: REDUCE, REUSE, and then RECYCLE. Choose certain objects found and talk about ways to reduce and reuse the litter and if it can be recycled. Some examples:

  • Plastic bottle- use a thermos/refillable water bottle that can be used over and over again
  • Plastic bag- use a canvas or reusable bag
  • Straw- don’t use a straw, you don’t need it
  • Sandwich bag- use a reusable, washable container for food

16. On your own, input the data collected and pictures you take using the Litter-free App (see beginning of Procedure on how to create your account). Share with parents, colleagues, and students!

  • What can your school do to help with litter?
  • What can you do at home to help with litter?

Section 5: Assessment

Invite each student to make a poster about their experience. They can choose one of the litter items that they found and focus on ways to reduce, reuse and recycle it, and why it is important to help. They should include their own slogan to help reduce, reuse, and recycle. Their ideas can be expressed through pictures and words and then displayed in the classroom, hallway, or somewhere in the school (cafeteria) to get the message out that litter-free starts with me!
