Teach Engineering: What Floats Your Boat?
Learners 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...

Serc: Water Activity
Students investigate water by estimating how long it takes to freeze, then see if the ice cube will float in water, and eventually work with other items to see if they sink or float in water.

Nagt: Density Mystery Canisters
Students experiment with items that sink or float, and learn that water's density is equal to one, and objects/solutions with a density greater than one will sink, and those with a density less than one will float.

Serc: Mn Step: Sink or Float: All Liquids Do Not Have the Same Density
An experiment in density. After a review of floating and sinking of different materials, students test four bottles, all holding four ounces of water, to see if they will float or sink. They each contain a different density of sugar...

Serc: Mn Step: Sink or Float? Inquiry Investigation
For this activity, students make predictions about whether different objects float or sink, then test them. They are asked to record their observations and results for each, and compare their results to others'.

Fun Science: Sinking and Floating Soda Cans
Why do some pop cans float in water while others don't? This easy experiment is a great example of the principle of density.

Teach Engineering: Floating and Falling Flows
Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a...

Serc: Mn Step: Sinking Water: Glaciers, Ocean Currents and Weather Patterns
A lesson where students learn how warm water is less dense than cold water, and what this means for global climate change as ice from the polar regions melts. Students will do experiments in buoyancy and water density when hot or cold,...
