In this lab experience, students carry out an investigation to determine how consistent tree growth has been in samples. They determine how the climate has fluctuated over the last 10 years based on annual growth ring size. By comparing tree ring growth and climate data, students gain a better understanding of how variation in climate influences organisms. They also replicate the methods used by climate scientists to gather climate data from hundreds of years ago.
