What This Standard Means

What Students Need to Do

Students read data on fossil fuel CO2 emissions and CO2 levels in the air. They describe how both change over time. They recognize that CO2 is a greenhouse gas.

What Mastery Looks Like

A student uses dates and numbers from a table to describe the trend in each measure. They explain that yearly emissions differ from the CO2 already in the air, and that CO2 data do not show whether methane changed.

Common Misconceptions

Students may think CO2 is separate from greenhouse gases. They may mistake yearly emissions for the amount already in the air or assume that rising CO2 means every greenhouse gas is rising.

How to Assess It

Exit ticket: In 2000, fossil fuel CO2 emissions were 25 billion tons and atmospheric CO2 was 370 parts per million. In 2019, they were 36 billion tons and 411 parts per million. Describe what changed, and identify which numbers measure CO2 already in the air.

Lesson moves

Ways to Teach It

  1. Give pairs cards with the exit ticket's years and four measurements; have them assemble a table and mark the trend in each column.

  2. Show the exit ticket data and ask, "Does this prove methane increased too? What evidence would you need?"

  3. Play evidence or guess: students hold up E or G for claims about the exit ticket data, then cite a number.

  4. Show a sample gas bill with 30 and 60 therms in two months; ask which month's gas use likely released more CO2.
