Comment on this resource
In this lesson students discover how growth rates of corals can be estimated from samples collected at a single point in time. Students will identify and briefly explain two methods for estimating the age of hard corals, learn how oxygen isotope ratios are related to water temperature, and interpret data on oxygen isotope ratios to make inferences about the growth rate of deep-sea corals. This hands-on activity uses online data resources and includes: focus questions, background information, evaluations and extensions, as well as resources and student handouts.
