Activity 01
Data Analysis: Ice Core CO2 and Temperature Records
Provide students with simplified graphs of CO2 concentration and temperature deviation reconstructed from Antarctic ice cores over the past 400,000 years. Students annotate cycles, identify the correlation between CO2 and temperature, and write a claim-evidence-reasoning paragraph explaining what the data shows.
Explain what evidence we have that the Earth's climate has changed over time.
Facilitation TipDuring Data Analysis, circulate to listen for students connecting CO2 spikes with temperature changes, not just describing trends.
What to look forProvide students with a simplified graph showing CO2 levels from an ice core record and a separate graph of global temperature from instrumental records. Ask them to write two sentences describing the relationship they observe between CO2 levels and temperature.
