This lesson shows that different foods have different environmental impacts. Students will calculate ratios and practice proportional thinking.
Step 1 - Inquire: Students explore an interactive bar graph showing the resources it takes to create our food.
Step 2 - Investigate: Students select different foods that they wish to compare. Students complete a series of mathematical calculations showing their knowledge of arithmetic and ratios.
Step 3 - Inspire: In groups, students discuss what they have learned and answer several questions.
Teacher creates groups of 3-4 students each.
Each group of students selects three pairs of foods each.
