There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water, the density of aluminum using water displacement, and the density of several cylinders using graphical analysis.

Instructional Ideas

• Connect the lesson to Archimedes and buoyancy

Classroom Considerations

• Use care when adding the aluminum to the graduated cylinder to prevent the glass from breaking
• Requires prior knowledge of how to solve basic formulas and plot points to create a line graph

Pros

• Includes a pre-lab assignment to ensure pupils have read the instructions before beginning
• Highlights all formulas required

Cons

• None
