Lesson 7 - Negative numbers under the sea

In this resource students are asked to help a team of scientists to investigate Lexington Seamount, a newly named underwater volcano located in the Coral Sea, off of Australia's east coast.

Using multibeam mapping technology, scientists have been able to produce maps of extinct underwater volcanoes that have not been thoroughly investigated before. In order to investigate the volcano and and the surrounding waters so that they can better understand the environment and the area, students will need to measure the distances under sea level and work with negative numbers.

The materials contain a detailed presentation, student worksheet and solutions.
