Using "mystery bathymetry" shoeboxes, young explorers simulate sonar action to map out the topography of an un-viewable landscape. This classic activity helps physical oceanography learners understand how sonar works. It would be...

Take young scientists into the depths of the world's ocean with the second instructional activity of this three-part earth science series. After first drawing pictures representing how they imagine the bottom of the ocean to appear,...

Students examine the components of a sonar system. In this physical science instructional activity students explain how multibeam and sidescan sonar systems are useful to ocean explorers.  Students simulate sonar operations in an...

Earth science learners create a two-dimensional topographic map of the floor of the Aegean Sea. They use it to then create a three-dimensional model of the ocean floor features. This comprehensive resource delivers strong background...
