In this instructional activity, students will investigate why the Cartesian diver dives and rises in a 2 liter bottle. They will also, through their own discovery, come up with a question and then change one variable and record their...

Through this curricular unit, students are introduced to the important concept of density. The focus is on the more easily understood densities of solids, but students may also explore the densities of liquids and gases. Students devise...

Students observe Archimedes' principle in action in this challenge where a toy boat is placed in a container of water and a rock is placed on the floating boat. Students must explain why the water level rises/falls/stays the same based...

In this activity, students investigate the history of density, its uses, and applications. Students will generate and calculate data applying it to a graph. They will be looking at the relationship between mass and volume.

Students follow the steps of the engineering design process as they design and construct balloons for aerial surveillance. After their first attempts to create balloons, they are given the associated Estimating Buoyancy lesson to learn...

Five lessons about the study of fluid mechanics. The unit concludes with students applying what they have learned to determine the stability of individual above-ground storage tanks given specific storm conditions so they can analyze...
