This lesson has activities where students will learn about buoyancy and explore how hot water rises and cold water sinks. As an extension and real-life application, students will see that glacial run-off is occurring at a rapid pace and the cold glacial water could potentially change ocean currents thus influencing global climates.

In this experiment, students create a "lava lamp" - a beaker on a hotplate, and investigate buoyancy, convection and other fluid and thermodynamic properties using ink, water, vegetable oil and Alka-Seltzer tablets. The activity is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

In this design challenge, students learn about the Vikings from an engineering point-of-view. While investigating the history and anatomy of Viking ships, they learn how engineering solutions are shaped by the surrounding environment and availability of resources. Students apply this knowledge to design, build and test their own model Viking ships.

Students use modeling clay, a material that is denser than water and thus ordinarily sinks in water, to discover the principle of buoyancy. They begin by designing and building boats out of clay that will float in water, and then refine their designs so that their boats will carry as great a load (metal washers) as possible. Building a clay boat to hold as much weight as possible is an engineering design problem. Next, they compare amount of water displaced by a lump of clay that sinks to the amount of water displaced by the same lump of clay when it is shaped so as to float. Determining the masses of the displaced water allows them to arrive at Archimedes' principle, whereby the mass of the displaced water equals the mass of the floating clay boat.
