Video addresses warming of ocean temperatures as recorded since 1954, by scientists in the Bermuda Institute for Ocean Sciences (BIOS), and the potential impact of rising temperatures on thermal expansion in oceans, rising tides, heat energy added to storms, and changes in marine food chains. Comments from expert scientist: An excellent activity. Shows thermal expansion of seawater in a simple, straightforward, hands-on exercise. Good links for teachers and students to follow/explore.
