Old VersionNew Version
1<p>In this computer-based activity, students download, graph, and analyze authentic satellite temperature data for coral reef sites around the world. The activity includes a mapping component so the students work individually on one particular coral reef location and then the findings for the whole class are summarized on a set of world maps. After observing global trends in the data, students evaluate the threat to coral reefs from heat stress, which has been occurring with increased intensity and frequency in recent years.</p>  1<p>This activity uses coral bleaching as the context to review redox chemistry concepts. The activity is in two parts:</p>

4  4   <li><strong>Coral_Bleaching_and_SST:&nbsp;</strong>Students review basic coral biology and use the NOAA Coral Reef Watch online database to obtain authentic data for sea surface temperature (SST) at one of four coral reef regions. The students then use Excel to analyze SST trends and compare results between student groups and make predictions for coral bleaching risk. This is a version of&nbsp;the exercise developed by K. Grayson, which is also posted on this same HHMI Biointeractive QUBES collection site.<br />

   6   <li><strong>Radicals_and_Coral_Bleaching:</strong>&nbsp;In this classroom or homework activity, students first review the concepts of the&nbsp;<em>Q</em><sub>10</sub>temperature coefficient, oxidation-reduction (redox) reactions, free radicals, and antioxidants. This is then placed in the context of the prior activity on coral bleaching and SST, and a recent study (Young et al.,&nbsp;2016) examining genetic differences in corals across a latitudinal gradient that may contribute to greater antioxidant capacity in warmer climates. The activity includes 12 questions that would ideally be administered as in-class active learning questions, but could also be homework&nbsp;or an in-class quiz.</li>
