Activity 7:
Temperature vs. Carbon Dioxide
Level: Grade 7-8. Also includes a more advanced version for older
(Algebra 1 or Science) students
Learning Objective: Students will graph Carbon Dioxide levels against
Temperature change to see the trend of one against the other, using
actual ice core data.
Specific Science Content Standards
- Changes in earth and sky
- Structure and evolution of an earth system's history
- Risks and benefits
- Geography: how to apply geography to analyze the past
Specific Mathematics Content Standards
- Variables and data
- Plotting and graphing
- Fitting to straight lines
- (extended version: correlations, logarithms, exponential functions)
Earth Update: Atmosphere
Introducing the activity:
Tell students that ice cores can help us learn not only the temperature
of the Earth in times past, but also the amount of Carbon Dioxide
trapped in the air bubbles in the ice. This activity uses as source
data a plot of each versus time, and asks the students to plot one
variable (the Temperature) versus the other variable (the Carbon Dioxide
content). Students can fit the data to a line y = mx + b to see how
changes in Temperature and related to changes in Carbon Dioxide. The
extended version has actual data tables to plot, and a discussion
of exponential functions (Earth population)
