Delve into the concept of density through engaging activities focused on the Titanic's tragic sinking. In this lesson, students will measure the mass and volume of water to derive the density formula and predict whether objects will float or sink based on their density. The lesson includes a hands-on experiment with leaf disks that will rise and sink based on oxygen production during photosynthesis. Students will also reflect on careers where density plays a crucial role, composing a written response that connects their learning to real-world applications.

Density – the Reason the Titanic Sank Jessica Wetherington Ann Williams Putnam City
Engage • Teacher Demo – Can you make an orange sink?
Explore • Students measure the mass and volume of water, plot data on a graph, and derive the density formula
Explain • Students predict if objects will float or sink based on density and explain their reasoning
Elaborate • Students will sink leaf disks. As the leaves produced oxygen during photosynthesis, they will rise.
Evaluate • Writing prompt – • Using what you have learned about density, think about a career where the concept of density is important. Write at least 5-7 sentences about the career and how the concept of density is used.
