True love has the right ratio. In this humorous animation, the number of words spoken by each partner predicts whether a date goes well or horribly. What do you do when someone asks if you listen to country music backwards, but won't let you get a word in edgewise?

The Carbon Footprint of Food
Conditional Remix & Share Permitted
CC BY-NC
Rating
0.0 stars

SYNOPSIS: This lesson shows that different foods have different environmental impacts. Students will calculate ratios and practice proportional thinking.

SCIENTIST NOTES: This lesson is thoroughly sourced. It is engaging and suitable for students to understand how to measure carbon footprint from food sources. The activities in the lesson would also enable them to build their quantitative skills to determine the extent of CO2 impact on the environment. The lesson has passed our science review, and it is advised for classroom use.

POSITIVES:
-This lesson is great because it shows that different foods have different environmental impacts.
-It shows the great disparity between certain types of foods. For example, creating 1 kg of beef (from a beef herd) emits 99.48 kgCO2eq. Creating 1 kg of potatoes creates only 0.46 kgCO2eq. Raising beef creates more than 200x the carbon dioxide than raising the same amount of potatoes!

ADDITIONAL PREREQUISITES:
-You will need to share the Student Slideshow with students and grant them editing rights. They will all be writing in the same slideshow.
-In general, animals and animal products use far more resources than plants.
-Kilograms are used in this lesson. Some students will be unfamiliar with this unit. You can read more about the kilogram at Britannica. An easy conversion from kilograms to pounds is 1 kg = 2.2 lbs.
-Kilograms of CO2 equivalent are also used in this lesson. This is pretty abstract for the students. You can have them imagine holding a 2.2-pound ball in their hands. This ball has mass and takes up space. This is the "pollution" generated when creating different foods.

DIFFERENTIATION:
-You can create groups of students with mixed abilities.
-If a group finishes early, you can ask these extension questions:
-"Food 1’s emissions are what % of food 2’s emissions?"
-"Can you convert your answers from kilograms to pounds?"
-The Investigate section features a completed table of calculations. You can use this before the students begin their calculations. You can also share this with certain students or groups and let other groups complete their calculations on their own. Another option is to have students use the completed table to check their thinking when they are finished. There is a walkthrough of calculations in the speaker notes of this slide.

Putting Math to Work

Type of Unit: Problem Solving

Prior Knowledge

Students should be able to:

Solve problems with rational numbers using all four operations.
Write ratios and rates.
Use a rate table to solve problems.
Write and solve proportions.
Use multiple representations (e.g., tables, graphs, and equations) to display data.
Identify the variables in a problem situation (i.e., dependent and independent variables).
Write formulas to show the relationship between two variables, and use these formulas to solve for a problem situation.
Draw and interpret graphs that show the relationship between two variables.
Describe graphs that show proportional relationships, and use these graphs to make predictions.
Interpret word problems, and organize information.
Graph in all quadrants of the coordinate plane.

Lesson Flow

As a class, students use problem-solving steps to work through a problem about lightning. In the next lesson, they use the same problem-solving steps to solve a similar problem about lightning. The lightning problems use both rational numbers and rates. Students then choose a topic for a math project. Next, they solve two problems about gummy bears using the problem-solving steps. They then have 3 days of Gallery problems to test their problem-solving skills solo or with a partner. Encourage students to work on at least one problem individually so they can better prepare for a testing situation. The unit ends with project presentations and a short unit test.

Students work in a whole-class setting, independently, and with partners to design and implement a problem-solving plan based on the mathematical concepts of rates and multiple representations (e.g., tables, equations, and graphs). They analyze a rule of thumb and use this relationship to calculate the distance in miles from a viewer's vantage point to lightning.Key ConceptsThroughout this unit, students are encouraged to apply the mathematical concepts they have learned over the course of this year to new settings. Help students develop and refine these problem-solving skills:Creating a problem-solving plan and implementing the plan systematicallyPersevering through challenging problems to find solutionsRecalling prior knowledge and applying that knowledge to new situationsMaking connections between previous learning and real-world problemsCommunicating their approaches with precision and articulating why their strategies and solutions are reasonableCreating efficacy and confidence in solving challenging problems in the real worldGoals and Learning ObjectivesCreate and implement a problem-solving plan.Organize and interpret data presented in a problem situation.Analyze the relationship between two variables.Create a rate table to organize data and make predictions.Apply the relationship between the variables to write a mathematical formula and use the formula to solve problems.Create a graph to display proportional relationships, and use this graph to make predictions.Articulate strategies, thought processes, and approaches to solving a problem, and defend why the solution is reasonable.

Getting Started

Type of Unit: Introduction

Prior Knowledge

Students should be able to:

Understand ratio concepts and use ratios.
Use ratio and rate reasoning to solve real-world problems.
Identify and use the multiplication property of equality.

Lesson Flow

This unit introduces students to the routines that build a successful classroom math community, and it introduces the basic features of the digital course that students will use throughout the year.

An introductory card sort activity matches students with their partner for the week. Then over the course of the week, students learn about the routines of Opening, Work Time, Ways of Thinking, Apply the Learning (some lessons), Summary of the Math, Reflection, and Exercises. Students learn how to present their work to the class, the importance of students’ taking responsibility for their own learning, and how to effectively participate in the classroom math community.

Students then work on Gallery problems, to further explore the resources and tools and to learn how to organize their work.

The mathematical work of the unit focuses on ratios and rates, including card sort activities in which students identify equivalent ratios and match different representations of an equivalent ratio. Students use the multiplication property of equality to justify solutions to real-world ratio problems.
