Emissions by Mode of Transportation (Green Transportation #2)

Synopsis

In this lesson students compare and contrast emissions from different modes of transportation and explore the concept of transportation planning. 


Step 1 - Inquire: Students analyze a bar graph of carbon dioxide emissions by different modes of transportation and calculate the most environmentally conscious modes of travel based on emissions.


Step 2 - Investigate: Students analyze commuter survey results of the top concerns with public transportation and complete real-world math problems based on different transportation scenarios, calculating the difference in carbon emission outputs.


Step 3 - Inspire: Students reflect on how transportation systems are created and are introduced to the role of transportation planners and Hong Kong's world-class transit system.

Accompanying Teaching Materials
Inquire
10 minutes
  • Teacher asks students which mode of transport from the chart they use the most for transportation (connection to self).
  • Teacher shows graph of carbon emissions data and asks students responsive questions:
    • Which mode of transport emits the most amount of CO2? The least? By how much?
    • An SUV emits ___ more pounds of CO2 per mile than a small car.
  • Students use the equation listed on slide 9 to determine the most environmentally conscious modes of travel.
Investigate
20 minutes
  • Teacher defines public transportation and reveals the results of commuter surveys, showing commuters' top 10 concerns with public transportation.
  • Students brainstorm what changes the city could make to help solve these problems.
  • Students use Google Maps to route themselves to various locations using the school as their starting point. Students use the same equation from the Inquire section to determine their carbon footprint using different modes of transportation.
Inspire
20 minutes
  • Teacher introduces the role of transportation planners in a city.
  • Students engage in scenario-based questions to understand the role of transportation planners.
  • Teacher shows the video How Hong Kong Built the World's Best Transit, demonstrating how Hong Kong built one of the world's best transit systems.
  • Students participate in turn-and-talk discussions with peers to compare Hong Kong's transit system to the transit system in their community.
Teaching Tips

Positives

  • This lesson builds upon students' understanding of place in the world and the impact of individual lifestyle choices.
  • It features relevant real-world math problems.
  • It offers career path integration in the sector of transportation planning and transit.
  • Students creatively brainstorm solutions for real-world issues and civil concerns.

Additional Prerequisites

  • This is lesson 2 of 6 in our 3rd-5th grade Green Transportation unit.
  • Students should have knowledge of reading a bar graph and a basic understanding of interpreting data.
  • If students do not have background knowledge of their community's public transportation systems, they should be appropriately introduced to the basics of how buses, metros, and railways work.

Differentiation

  • There can be number-set choices for math problems available for different abilities and skill sets.
  • Students can work in pairs or small groups.
