Learners research the development and implementation of a research vessel/vehicle used for deep ocean exploration. For this oceanography lesson, students calculate the density of objects by determining the mass and volume.

Students determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume graph.

Students work together to create a watershed model. They discover the flow of surface water on different topography. They examine how materials originate from miles away and end up in a different wetland.

Young scholars read poem, "The Bridge," by Henry Wadsworth Longfellow, discuss how they are connected to other human beings, both past and present, and create time capsules including their favorite memorabilia.

Students explore an estuarine system to gather data on density driven currents. This type of current is contrasted with temperature and wind driven currents.

A instructional activity and activity sheet on buoyancy. Students add weight to a helium-filled balloon to keep it suspended so that it won't float or sink, but instead will 'flink.'

Learn about density in this hands-on science experiment. Includes full list of materials, procedures, and scientific explanation of what makes an object float or sink. [PDF]
