• Compare pH and CO2. CO2 in solution with water
becomes carbonic acid, dropping the pH, so measuring relative pH should indicate relative levels of CO2.
• Measure particulates • Discussion Questions • Answer Ice Core Research

Greenhouse Effect.doc Purpose Measure the effect on temperature of a greenhouse gas (carbon dioxide—CO2) on a
simulated atmosphere and compare this data against an atmosphere with lower levels of CO2.

Objectives:Students will:• Discuss the benefits of long-term data sets
and studies • Use a long-term data set to plot graphs and
examine patterns• Extrapolate what future climates may be like• Use empirical data to discuss how human
activity is affecting the planet
