Float or Sink?
Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...
Curated OER
Anthony's sink or float game
Students explore the concepts of float and sink by playing a game where they build things on mud, water, rock and jelly. In this Anthony's sink or float game lesson, students discover what materials remain strong in various conditions....
Curated OER
Density Laboratory Gizmo
In this mass worksheet, learners fill in a chart with different items and their volume, whether they float or sink, and their density. Students complete this for 10 items and answer 6 multiple choice mass questions.

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.'

Serc: Mn Step: Solid and Liquid Density Investigation
For this activity, students investigate whether objects and liquids float or sink when placed in water. As they proceed, they will develop an understanding of what density is. Student handouts are provided.

Serc: Mn Step: Sinking Water: Glaciers, Ocean Currents and Weather Patterns
A instructional activity 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...
Science is Fun
Science Is Fun: The Cartesian Diver
A simple experiment in buoyancy where you discover how to make a packet of sauce or candy float or sink at will, and why you are able to do this.
