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,...

Serc: Investigating Density in Solutions: How Can You Make an Egg Float?
In this activity, students will learn about density by determining how to make an egg float in water. By the end of the lesson plan, students will understand that density and weight are different and that density matters in floatation....

The Engineering Place: Balloon Flinking [Pdf]
A lesson and activity sheet on buoyancy. Students add weight to a helium-filled balloon to keep it suspended so that it won't float or sink, but instead will 'flink.'
