Why Lesson Planet?
Analyze and graph oxygen isotope ratios in coral samples in relation to the distance from the outer skeleton edge. Compare the data to the mean monthly water temperatures. Uncover whether or not there is any correlation. In addition to instructions and handout for the activity, there are several resource links to background information and details on the associated Trondheimsfjorden expedition, during which this data was collected. Use this in your high school biology class.
