In this activity, students use real data on fossil pollen from a lake in Washington State to study climate change. Working in teams, they separate simulated pollen grains from 'sediment samples,' identify them, and determine what climate the plants that produced the pollen grains might have lived in. They will then graph their data and discuss the results. Information cards on the plants, data cards for recording pollen counts and plant species, and a blank graph for displaying data are provided.
