1 Ecological Footprint By Dimitra Pyrpiris Title: Ecological Footprints Subject/Course: Science Time: 230 Minutes (3.5-4 periods) Strand: Understanding Life Systems and Biodiversity Grades: Grade 6 Lesson Description Students will be considering a variety of discussion questions in order to thoroughly understand that humans do affect the natural environment. Humans also benefit from biodiversity, and once biodiversity is diminished, problems will occur. Students will use the following website to calculate their ecological footprint: ( Once this has been done the class will get the opportunity to discuss their ecological footprint, what it means to them, and brainstorm ideas of minimizing their impact on the environment. Students will be able to propose how they can play a part in minimizing their impact on the environment. Spreading the word to friends and family will promote awareness and allow students to promote change. Stage 1: Desired Results Fundamental Concepts/Skills An understanding of how human impact on the environment Awareness that different groups of people relate to the natural environment differently (i.e. business owners, mine owners, local first nations peoples, etc.) Ways of minimizing our impact on the environment The importance of respecting and preserving biodiversity An understanding of the how society benefits from biodiversity Population sustainability Big Ideas Humans make choices that can have an impact on biodiversity Ontario Curricular Overall Expectation Assess human impacts on biodiversity, and identify ways of preserving biodiversity; Ontario Curricular Specific Expectation Analyze a local issue related to biodiversity (e.g., the effects of human activities on human biodiversity, flooding of traditional Aboriginal hunting and gathering areas as a result of dam construction), taking different points of view into consideration (e.g., the points of view of members of the local community business owners, people concerned about the environment, mine owners, local first nations, Métis, Inuit), propose action that can be taken to preserve biodiversity, and act on the proposal. Asses the benefits that human societies derive from biodiversity (e.g., thousands of products such as food, clothing, medicine, and building materials come from plants and animals) and the problems that occur when biodiversity is diminished (e.g., monocultures are more vulnerable to pests and diseases). Lesson Goals By the end of the lesson students will be able to analyze issues related to biodiversity and the effects of human activity on biodiversity Based on their knowledge obtained in the lesson the students will research a country of their choice and learn how and why certain countries have a larger or smaller ecological footprint than other countries. To motivate students to think about how they can minimize their ecological footprint. Students will keep track of

2 the decisions they make that may affect the environment and reflect on why it is important to minimize their footprints. To motivate students to spread the word to family and friends. Key concepts and/or skills to be learned/applied: Background Knowledge: See Ontario Curriculum concepts, ideas, What and who makes up our community expectations Environmental concerns present in the media Stage 2: Planning learning experience and instruction Student Groupings Instructional Strategies Whole class discussion/brainstorming Guided Inquiry Small group discussions/assignments Cooperative learning Materials Computers Questionnaire handout (Handout#1) Group discussion worksheet (Handout#2) Research sign-up sheet (Resource#3) Considerations Students may present their projects to the class in any format they wish. They are able to use their creativity to present their findings. Students can create their own awareness campaign and motivate others to minimize their ecological footprints. Guiding research questions (Handout #4) Home connection worksheet (Handout #5) Observational checklist used for assessment (Resource #6) Accommodations This lesson includes a variety of different aspects that will accommodate many learners. For students who are having difficulty with reading or comprehension the teacher will be reading and explaining the questions on the ecological footprint survey while students are filling it out in the computer lab. This will allow students to ask questions and follow along at a good pace. Students can work in groups with a variety of abilities for support. Teacher can create groups to his/her discretion. Stage 3: Learning experience and instruction Motivational Hook (5 MINS.): Period 1 Show students a hypothetical footprint. Tell them that depending on how people interact with their environment, it is possible to have a very large footprint. Post 10 pictures of a globe on the front board and ask the class: Is it possible for someone to have such an impact on the environment that they would need 10 worlds to sustain our environment? Open (15 MINS.) : Period 1 To assess prior knowledge, the lesson will begin with the question What are some environmental concerns that you have heard about in the media? A class discussion will take place about the ideas that have been brainstormed. A definition can be presented to the class to get them understanding the idea of what an ecological footprint is. This definition was found on the above website that will be used to calculate the students ecological footprints. Our ecological footprint represents the land and water it takes to provide us with the things we use and to absorb our wastes. The land and water can be anywhere in the world, from a local landfill to a distant apple orchard. Our

3 footprints bring it all together to produce a single measure of impact. Ecological footprints are useful because they account for decisions we make about food, shelter, mobility, and goods and services. They can be calculated for individuals, buildings, communities, countries, and the entire human population. Some activities increase our footprints because they release carbon in the form of greenhouse gasses, especially carbon dioxide. With this definition, much more discussion will arise. We can continue to discuss how our choices, such as what we eat, how we get to school, where we live etc., can have an impact on the environment. Body (70 MINS.) Computer survey (30 MINS.), Group discussions (20 MINS.), Class discussion (15 MINS): Periods 1-2 To minimize any disruption and transition time, the lesson will begin in the computer lab. This will keep the class focused and allow for a steady transition into the rest of the lesson. The students will be given a handout (Handout #1) to record their answers while calculating their ecological footprints. The teacher will read each question aloud and the class will answer the questions at the same time. This will ensure that every student is on the same page and the teacher can address any questions or concerns throughout the questionnaire. Once they have completed the questionnaire, the students must then complete the remaining questions on the handout that was provided to them (Handout #1). This will give them the opportunity to navigate the website and try to figure out where they can obtain that information. This information will allow them to conceptualize further what their individual impact is on the environment and how it differs from other people in other parts of the world. Students will continue the lesson in the classroom. Students will be put into groups of four to discuss their ecological footprints amongst each other. This will give them the opportunity to make connections and understand why and how their footprints are the same or different. Students will be given Handout #2, which lists important questions they will be answering with their groups. This will give each group the opportunity to share their ideas about the environment, how and why it is negatively impacted, and how we can make an effort to minimize our footprint. Once students have filled in their worksheets, we will get together as a class and each group will share their answers with the rest of the class. Allow for discussion throughout presentations. Dialogue between the groups is important. Close (140 MINS): Discussion/Introduce project (15 MINS.), library research time (120 MINS- 2 Periods), Home connection introduction (5 MINS.): Periods countries were compared in terms of their varying ecological footprints. Students were asked to list the countries and their ecological footprints on one of the provided worksheets. Thus, they should already have a sense of which countries have had the most and the least impact on their biodiversity. The teacher will start a discussion with the class on why they believe certain countries ranked higher than others in terms of their ecological footprints. Connections can be made to food, transportation, waste, housing, and so on. Students will be told that they will be getting into groups to research a country. They must learn about how and why certain countries have a larger or smaller ecological footprint than other countries. Time will be allocated for the library and the computer lab to gather the necessary information to complete their assignment. Approximately 2 class periods will be dedicated to library and computer research time. In groups, students are able to use their previous worksheets as guidelines on what to look for when researching. Handout #4 will also be provided to students to help guide their research and organize their findings. Essentially, students will be trying to understand why certain countries are ranked the way they are. Through research, students will be able to answer this question and present their findings to the class.

4 Students will present their projects to the class. There will be two days of presentations. The way they present their information is up to them. Creativity is encouraged, but this will give the students an opportunity to think outside the box and present in their own way. Once students have completed their presentations it will be their turn to start thinking about what they can do to minimize their ecological footprints. Handout #5 will be provided to the students so that they can take home to discuss with their families how they can minimize their footprints, how they will keep track of it and why it is important. Link to Future Lessons Whole class discussion to debrief students on learning experiences. Through spreading awareness and home connections, students can create their own awareness campaign and motivate others to minimize their ecological footprints. Assessment An observational checklist will be used for assessment. The observational checklist is provided (Resource #6).Essentially, the following criteria will be assessed: - Students are able to Analyze a local issue related to biodiversity (e.g., the effects of human activities on human biodiversity, flooding of traditional Aboriginal hunting and gathering areas as a result of dam construction), taking different points of view into consideration (e.g., the points of view of members of the local community business owners, people concerned about the environment, mine owners, local first nations, Métis, Inuit), propose action that can be taken to preserve biodiversity, and act on the proposal. - Students are able to Asses the benefits that human societies derive from biodiversity (e.g., thousands of products such as food, clothing, medicine, and building materials come from plants and animals) and the problems that occur when biodiversity is diminished (e.g., monocultures are more vulnerable to pests and diseases). - Students will be able to Assess human impacts on biodiversity, and identify ways of preserving biodiversity; - Students use their time productively - Students reflections show a sincere motivation to make a change - Students research material was mostly academic and students provided a quality research information - Students used proper grammar/vocabulary in their worksheets, and presentations. Student used key vocabulary that was learned throughout this lesson.
