  • Subjects: Science, Language Arts
  • Suggested Time: 2 hours

Materials

Light meters (available commercially), Day Lighting Worksheet, the Ohio School Design Manual light level chart (make copies or display by projector), and colored paper and markers.

Ohio 2010 Standards

Science:

  • Changes in an organism’s environment are sometimes beneficial to its survival and sometimes harmful. (4)
  • Light and sound are forms of energy that behave in predictable ways. (5)
  • The sun is one of the many starts that exist in the universe. (5)
  • Science inquiry and applications. (4-6)

Language Arts:

  • Refer to details and examples in a text when explaining what the text says explicitly and when drawing inferences from the text. (4)
  • Interpret information presented visually, orally, or quantitatively. (4)
  • Determine or clarify the meaning of unknown words and phrases based on grade level reading and content, choosing flexibly from a range of strategies. (4, 5)
  • Determine the meaning of words and phrases as they are used in a text, including figurative, connotative and technical meanings. (6)
  • Conduct short research projects that use several sources to build knowledge through investigation of different aspects of a topic. (4-6)
  • Draw on information from multiple print of digital sources, demonstrating the ability to locate an answer to a question quickly or to solve a problem efficiently. (5)
  • Gather relevant information from multiple print and digital sources; assess the credibility of each source; and quote or paraphrase the data and conclusions of others while avoiding plagiarism. (6)

Objectives

The student will be able to:

  • Define day lighting.
  • Answer reading comprehension questions from a selection about day lighting.
  • Measure light values with a Kill A Watt meter.
  • Compare data to the Ohio School Design Manual light level chart.
  • Identify where natural light can replace electric lights.

Introduction

  • Before students enter the room, open the shades or blinds, if there are windows. Leave the lights on. Once class begins, switch off the lights and ask students which lighting they prefer. Usually students prefer natural light. Help students identify natural vs. electric light.
  • Ask the students to briefly discuss why they prefer natural light. If needed, help them connect their preference for the lights being off to a preference for natural light. Possible answers include that natural light is more calming, comfortable, not too bright, and that people like sun.
  • Explain that today they will use a light meter to study one method of reducing cost and energy use, called day lighting.

Activities

  • Distribute a copy of the Day Lighting Worksheet to each student. As a class or individually, students should read the selection about day lighting and the answer questions. Go over answers to make sure students understand the answers.
  • Show students how to use a Kill A Watt meter by measuring the light in the classroom with the lights on and blinds shut vs. lights off and blinds open. Allow students to try it themselves from different places in the classroom. Students should record data in a log, noting where they measured the light, what type of light was present (natural, electric, or both), and the light value in foot candles.
  • As a class, search the school for locations where day lighting could be used. Use the light meter to measure the light value in foot candles. Try areas such as:
    • empty classrooms
    • hallways
    • cafeteria
    • offices
    • library
    • gym
  • Wherever possible, turn off electric lights to measure natural lighting.
  • Back in the classroom, help students compare their findings to the Ohio School Design Manual light level chart (distribute copies or display by projector). If students are not able to read the chart by themselves, just point out the appropriate values and ask if they are greater than or less than the values they measured.
  • Students should identify areas where lighting values exceed the Ohio School Design Manual recommendations, and list locations in the school where day lighting could be used to lower energy costs. Record on Day Lighting Worksheet.
  • Students can make signs and place them next to light switches and windows, reminding people to turn off the lights and open the blinds or shades during the day.

Extensions

  • Encourage students to create a day lighting plan for their homes. Students may discuss and implement the plan with their families.
  • Students may draw a design for a school or home that would optimize day lighting potential through the placement of windows. Help students to consider the direction of the sun throughout the day and orient the building accordingly. Display drawings in the classroom.

Closing

After reviewing the lesson, create a plan for using day lighting in the classroom. Under what conditions will natural light, electric light, or a combination be used?

  • Grade Level: 4-6
  • Subjects: Science, Social Studies
  • Suggested Time: 1 hour

Materials

Chalk/whiteboard, computers with internet access (ideally one per student), Carbon Footprint Worksheet, large paper or poster and markers (optional).

National Standards

Science:

  • Regulation and behavior.
  • Population and ecosystems.
  • Structure and function in living systems.
  • Science as inquiry.

Social Studies:

  • Environment and society.
  • Roles of the citizen.
  • Human systems.

Ohio 2010 Standards

Science:

  • Changes in an organism’s environment are sometimes beneficial to its survival and sometimes harmful. (4)
  • Organisms perform a variety of roles in an ecosystem. (5)
  • Science inquiry and applications. (4-6)

 

Social Studies:

  • People have modified the environment since prehistoric times. There are both positive and negative consequences for modifying the environment in Ohio and the United States. (4)
  • Variations among physical environments in Eastern and Western hemispheres influence human activities. Human activities also influence the physical environment. (5, 6)
  • The choices people make have both present and future consequences. (5, 6)

Objectives

The student will be able to:

  • Define greenhouse gas and carbon footprint.
  • Identify ways carbon dioxide is emitted.
  • Calculate individual carbon footprint.
  • Brainstorm ways to reduce carbon footprint.

Teacher Preparation

Carbon footprint is a calculation of the amount of greenhouse gas emissions (like carbon dioxide) an entity is responsible for. An entity may be a country, business, industry, or individual. The footprint measures the direct and indirect amounts of greenhouse gas emissions, which trap heat in the earth’s atmosphere. Carbon dioxide emissions also lower the quality of the air we breathe and contribute to other forms of pollution. The average American’s individual carbon footprint is over 20 metric tons, which is double that of people in other industrialized nations. To find out what your footprint measures, try the EPA’s online calculator at http://www.epa.gov/climatechange/ghgemissions/individual.html. Knowing the size of your footprint is a good first step toward reducing carbon emissions.

Introduction

  • Draw a footprint on the board and write “Carbon Footprint” above it.
  • Then, write the definition on the board: "the amount of greenhouse gases that are let into the atmosphere by a person or organization".
  • Explain that greenhouse gases, such as carbon dioxide, are harmful to the earth when too much is let into the atmosphere. Draw or display a diagram of the greenhouse effect, explaining that these gases cause the earth’s temperature to slowly rise. This can affect human, animal, and plant life. These gases can also pollute the air we breathe.
  • Explain that everyone has a carbon footprint, but some people’s carbon footprint is much larger. American’s carbon footprints are usually twice as big as people in other countries, which is bad for the earth. Tell students they will be calculating their personal carbon footprints and learning ways to shrink their carbon footprints.

Activities

  • Distribute the Carbon Footprint Worksheet to each student. Review the definitions of carbon footprint and greenhouse gas while students write them down.
  • To help students understand the last web site, you may need to tell them the chemical abbreviation of carbon dioxide, and the standard abbreviation for pounds.
  • Assign students to computers. They should write their answers on the Carbon Footprint Worksheet. Help students follow the worksheet instructions to log onto the web sites and answer the questions.
  • Regroup as a class. Ask students what causes greenhouse gases to be let into the atmosphere. Students may write these causes inside the drawing of the footprint.
  • Ask students to share their answers to the other questions on the worksheet. Students may write reduction strategies on a large paper or poster to hang in the classroom.

Extensions

  • Students may draw diagrams illustrating the greenhouse effect.
  • Students may research global warming to form an opinion on the issue.
  • Students may encourage their family members to calculate their carbon footprints using the web sites on the worksheet or the EPA’s carbon footprint calculator.

Closing

Ask students how they plan to change their carbon footprint.

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.
  • Research 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. You may wish to discuss why foods are imported, such as climate and soil conditions.
  • Ask students how food might travel from those locations. Students may write 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.
  • 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). Make a list as a class.

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.
  • Students may research why certain foods are imported from certain locations. For example, why do avocados often come from Mexico and California? Why do they grow best there? Are there other reasons for importing them?

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?

  • 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, more trash, and increasing damage to the environment. Today you will be learning more about what we do with trash and what impact trash has on the environment. Your goal will be to gather information and then come up with solutions for the waste problem."

Teacher Preparation

Note: This lesson will be most effective when used as an introduction to additional environmental education. The goal is to engage students’ prior knowledge of conservation and increase their interest in conservation strategies.

Introduction

  • Ask students to brainstorm what they can do to protect the earth. Ask them the “3 Rs” of protecting the earth/environment (reduce, reuse, recycle) to help them think of ideas.
  • Record ideas on the board, and ask a student to do or act out the tips immediately in the classroom, if possible.
  • For example, the students may open the blinds and turn off 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 energy conservation.

Activities

  • Distribute copies of the Green Monster Worksheet. Have students look up conserve in the dictionary and write the definition on the worksheet. Note: This lesson will be most effective when used as an introduction to additional environmental education. The goal is to engage students’ prior knowledge of conservation and increase their interest in conservation strategies.
  • Ask students what is conserved by the strategies they listed on the board. They should write what is conserved next to the idea. Explain that what is conserved is called a resource. Have students look up resource in the dictionary and write the definition on their worksheet. Then students should choose 5 ideas from the brainstorming to write on their worksheet.
  • Ask students why it is important to conserve resources. What might happen if the earth’s resources run out? Help them consider the effects on humans, animals, and plants.
  • Explain that the students will to create a poster encouraging others to conserve by taking simple steps like the ideas listed on the board. The poster will feature a cartoon character called the Green Monster. Discuss why conservation is called “green” or “being green.”
  • Have the students read the poster instructions aloud from the Green Monster Worksheet. Make sure students understand what a slogan is.
  • Break students into groups, where students should use scrap paper to design their Green Monster cartoon character and write their slogan and tips. Then they should use copy paper to sketch a draft of their poster.
  • Once the students’ draft has been approved by the teacher, students should work in groups to create a poster board with the art supplies.
  • 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.
