As a way for students to practice converting measurements within the same measurement system and across different measurement systems while also including issues of social justice into the curriculum, I developed this lesson.
Students need to be provided some background knowledge about Global Warming first. The teacher then needs to teach students that carbon emissions are represented in "Tonnes" which are 1000 kilograms. The whole point of the activity is to convert "Tonnes" to "pounds" to make the value of the measurement more familiar to Americans. Students will then present information in pounds on a poster to post around the school.
Students can choose their own nation's to measure. Some students choose to look at the carbon emissions of U.S.A. across three years or the carbon emissions of three countries over the course of one year.
Students take ownership of their work in this project. They also are able to apply scientific notation skills as numbers are so large calculators represent them in scientific notation.
