Weekly Round Up

Show the amount of waste produced weekly by using disposable lunch / snack products.

  • Grade Level: K-3
  • Subjects: Science, Social Studies, Math

Activities

The students will collect and count the amount of food wrappers, bags, and containers they dispose of on a weekly basis. Then students will create a bar graph to represent the data to others. After the first week, the students will explore ways to cut down on the amount of trash they produce and may present ideas to other classes. The students will then create a short report to present their findings to their parents. Challenge the class to reduce their lunch and snack trash.

Suggestions:

  • Use more eco-friendly wrappers such as unbleached, compostable wax paper baggies, or reusable stainless steel or plastic containers which are BPA free.
  • Encourage parents to buy snacks in bulk versus pre-packaged.
  • Encourage the use of stainless steel reusable bottles for their drinks.
  • Encourage the use of reusable lunch sacks (fabric, stainless steel, recyclable plastic).
  • Suggest making a worm composter for your classroom to compost the paper wrappers that are used.
  • Encourage home-made snacks versus pre-packaged.

  • Create a poster to inform others about paper use, environmental effects, and paper saving strategies.
  • Plan and advertise a school-wide No Paper Day, including a paper recycling drive.

Teacher Preparation

  • Gain support from the building principal and other staff to hold a No Paper Day.

Introduction

  • Ask students to brainstorm on the board all the ways that they use paper at school and at home (create two columns).
  • Ask students how the 3 “R’s” can be used to save paper.
  • Inform students that they will be sponsoring a No Paper Day for the whole school, which will combine reducing, reusing, and recycling strategies.

Activities

  • Ask students why it is important to save paper. Help them to understand that paper comes from trees. New trees can be planted, but it takes a long time for them to grow. Trees help clean the air we breathe, so if we don’t have enough trees, we won’t have enough clean air.
  • Ask students to use the “three Rs” to list ways to save paper. They may write their ideas on the board. Ideas may include using both sides of paper, using computers (email, scanning, electronic documents) instead of paper, printing on both sides of paper, using scrap paper, buying recycled paper, using thinner toilet paper, using less paper plates, napkins, and paper towels, and recycling paper and cardboard.
  • Go through the following tips for the No Paper Day:
  • Use no new paper, only scrap paper (already been put in the recycle bin).
  • Encourage students to bring lunches in reusable, non-paper lunch bags.
  • Art teachers should use non-paper mediums, preferably re-usable mediums such as canvas or clay.
  • Use paper alternatives such as the chalkboard, laptops (students may email teachers work), or individual whiteboards with refillable dry-erase markers to do classroom work.
  • Obtain permissions to unplug copiers and printers for the day, and create signs from scrap paper to explain the reason.
  • Identify exceptions for the No Paper Day (such as toilet paper, tissues, and cafeteria napkins).
  • Plan the No Paper Day campaign. Break students into small groups and assign one of the following activities to each group (choose those appropriate for your class):
  • Create posters advertising No Paper Day, including a paper recycling drive. Encourage students to bring lunches in a reusable lunch bag, and to bring paper from home for recycling collection.
  • Create a poster about ways to save paper and why it’s important. Students should present to the class and other classes if possible.
  • Write a letter using a computer word processing program, announcing and explaining No Paper Day to staff members. Type and email the letter to the staff listserv and ask staff to advertise No Paper Day to their students.
  • Write a PA announcement advertising No Paper Day, including the paper recycling drive. Students from the group may take turns reading the announcement on different days leading up to the No Paper Day, if possible.
  • Create signs to post on printers and copiers explaining why they are turned off during No Paper Day.
  • Hold the No Paper Day, including the paper recycling drive.

  • Students may create a plan for saving paper at home and present it to their families. They may hold a No Paper Day at home by turning off printers, using cloth napkins, purchasing recycled toilet paper, using only scrap paper for writing, etc.

Closing

  • Review the lesson and congratulate students on the success of No Paper Day.
  • Ask students to identify ways to save paper they could continue on a more permanent basis. Write the plan on the board and ask students to sign their names as a pledge to continue saving paper. Encourage students to be a spokesperson for ongoing paper-saving practices in their other classes.

Objectives

The student will be able to:

  • Read food labels to determine where foods have been shipped from.
  • Locate other states and countries on a map or globe.
  • Calculate the fuel cost of transporting the foods to local supermarkets.
  • Name foods that can be grown and purchased locally.

Introduction

  • Ask students where the food they eat comes from. How does it get to grocery stores?
  • Assign homework for students to look at the food in their homes and find an item from another state or country. Tell students they will learn where food comes from and what it takes to get from there to their plate.

Activities

  • Ask students what foods they brought and where the food came from. Make a chart on the board or overhead.
  • Students should locate those states and countries on a map or globe.
  • Ask students how food might travel from those locations. Students may draw a picture of the most likely type(s) of transportation next to the food on the chart.
  • Use an atlas, map with key, or web sites below to determine the approximate number of miles the food traveled. Add up the miles from all the food on the chart.
  • http://maps.nationalgeographic.com/maps -- world map
  • www.randmcnally.com – maps and mileage within US and Canada
  • www.mapcrow.info – mileage between international cities
  • http://www.fuelcostcalculator.com/ -- fuel costs and calculations for travel within the US
  • http://www.dieselboss.com/fuel.htm -- diesel fuel cost per gallon calculator for trucks.
  • If appropriate for the students’ ability level, calculate the approximate fuel cost for each item. Use the web sites above or local gas prices (this is more difficult for airplane, train or boat, so you may wish to limit this to US items and assume they traveled by diesel truck).
  • Students may add up the fuel cost from all the food on the chart.
  • For the item they brought in, students may draw a picture of its journey. If desired, provide copies of a map for students to trace their foods’ possible journey. Students can include the numbers of miles, fuel cost, and type(s) of transportation.
  • Ask students to imagine all the different foods they eat in a week, and how much fuel is used to transport those foods to local grocery stores. In addition to using fuel, transportation also causes polluting gases to be released into the air.
  • Ask students to think of ways to reduce the amount of money, fuel, and pollution caused by transporting food. How about buying locally grown food and planting a garden?
  • What types of foods can be grown in a garden in your region? Students may research this in books, on the internet, or by interviewing local gardeners (such as parents, students who live on farms, or a teacher). Draw pictures of these foods.

Modifications for K-1:

  • While K-1 students may not have the math skills required for this lesson, they can still learn about food’s journey and be exposed to geography at the same time.
  • Follow the same procedure, but skip the step of determining the mileage and cost. Instead, discuss and illustrate the impact transporting food has on the environment.

Extensions

  • Students may list the foods they eat for lunch and read the labels to determine where they came from. They may repeat the above activities to add the mileage and fuel cost for all foods. They may present this to their parents to raise awareness and encourage them to buy local foods whenever possible.
  • Try growing vegetable plant seedlings under a grow light in the classroom. When the seedlings are ready, send them home with students with planting instructions.

Closing

After reviewing the lesson, ask students how they might inform others about how transporting food affects the environment. What can they encourage others to do?

  • Explain what happens to trash after it is thrown out.
  • Identify waste and no waste lunch items.
  • Pack a no waste lunch.

Introduction

  • At lunch, meet the students in the lunchroom or have them eat lunch in the classroom. Ask them to keep all their trash on their desk or table after eating.
  • Point out how much waste was produced by one class in one day at lunch.
  • Reading the following passage to the students: Every day you throw away something. So do your friends, neighbors, and almost every person on earth. Right now the world population is 6.5 billion people, and the U.S. population is 300 million. That’s so many people throwing away lots of trash! So much trash is a big problem and raises some serious questions. Where will all the trash go? How does it affect our planet? What happens to the trash once it leaves a house? Are there solutions to this problem? This trash problem may not seem important now, but the problem will only get worse as you grow up and live in a world with more people and more trash hurting the earth. Today we will learn where trash goes and how to make less trash. We will also have a no waste lunch where everyone will pack a lunch that does not create trash.

Activities

  • With students’ lunch trash still in front of them, ask them how they could pack a similar lunch without making trash. Have students write ideas on the board.
  • Instruct students to throw away all the trash in the same bag(s) or can (except recycling) so they can see the cumulative waste of the class lunch. Ask students where trash goes after it is thrown out. (Landfill, dump, compost, or recycling.) For basic information on landfills & dumps see http://science.howstuffworks.com/environmental/green-science/landfill3.htm
    • You may wish to show a clip from the beginning of the movie WALL-E, which depicts the earth covered and destroyed by trash.
    • Ask students why composting and recycling are better options than sending trash to landfills.
  • Show students items or pictures of lunch or snack items. Some should be no waste while others have waste. (Individually pre-packaged or bagged in disposable items vs. packed in reusable containers.) Ask students to identify which make waste and which do not.
  • Don’t forget about napkins and utensils. Provide cloth napkins that day or encourage students to pack them. They should also bring reusable utensils.
  • Plan a no waste lunch day for later in the week. Students can make signs and pictures about the no waste day.
  • You may wish to allow for compost (organic materials like fruit peels & cores) and recyclable materials.
  • Hold the No Waste Lunch Day. Eat lunch together as a class and separate compost & recycling into appropriate containers.

Extensions

Closing

After reviewing the lesson, ask students how they can make less trash at home.

  • Give examples of how to reduce, reuse, and recycle.
  • Design a Green Monster cartoon character to encourage reducing, reusing, and recycling.
  • Decorate a poster encouraging others to reduce, reuse, and recycle.

Introduction

  • Ask students to brainstorm what they can do to protect the earth.
  • Record ideas on the board, and ask a student to do or act out the tips in the classroom, if possible.
  • For example, the students may open the blinds and turn off all or some of the lights, turn off the computer and/or monitor, put used paper in the recycling bin, use a re-useable lunch bag, clear objects away from heating vents, etc.
  • Explain that the students will be learning about how to reduce, reuse, and recycle.

Activities

  • Ask or tell students the “3 Rs” of protecting the earth (reduce, reuse, recycle). Write each one in a separate column on the board. Use the following definitions and examples, or adjust for your class:
    • Reduce: use less (electricity, water, paper, other goods, etc.)
    • Reuse: use again (fix broken things, give to someone else, find a new use, etc.)
    • Recycle: used items like glass, cans, paper, & plastic bottles can be turned into new items if they are sent to a recycling company instead of being thrown away.
  • Ask students why it is important to reduce, reuse, and recycle. What might happen if the earth runs out of water, gasoline (petroleum) for cars, electricity for lights, places to put trash, or energy for heat?
  • Help students think of more ways to reduce, reuse, and recycle, and record on the board. Students may act out these ideas if possible.
  • Explain that the students will create a poster encouraging others to reduce, reuse, and recycle by taking simple steps like the ones they listed. The poster will feature a cartoon character called the Green Monster. Discuss why reducing, reusing, and recycling is called “green” or “being green.”
  • Break students into groups, where students should decorate their posters with a Green Monster cartoon character. They should also write and/or draw ways to reduce, reuse, and recycle (one for each).
  • After the posters are finished, students should present them to the class. Then the students or the teacher should hang the posters in the school hallways.

Extensions

  • Students may present the posters to other classes or building staff.
  • Students may participate in the Energy Savings Patrol club and patrol the building for conservation opportunities. See the Energy Savings Patrol Teacher Guide for more information.
  • Students may create smaller signs for the classroom featuring the Green Monster, slogan, and 1 conservation tip. The signs may be posted near the area where the tip can be put into practice. For example, post a sign reminding people to recycle next to the trash can and recycle bin.

Closing

After reviewing the lesson, ask students which tips they plan to put into practice at home. Ask how they might encourage their family members to do the same.
