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: Down With the Clip!
Students see how surface tension can enable light objects (paper clips, peppercorns) to float on an island of oil in water, and subsequently sink when the surface tension of the oil/water interface is reduced by the addition of a...

Teach Engineering: Clay Boats
Each student uses a small quantity of modeling clay to make a boat that will float in a tub of water. The object is to build a boat that will hold as much weight as possible without sinking. In the process of designing and testing their...

Inquiry in Action: Changing the Density of an Object: Adding Material
In this activity, students see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float. This high-volume but light-weight material increases...

Inquiry in Action: Changing the Density of a Liquid: Adding Salt
In this activity, students will see that a carrot slice sinks in fresh water and floats in saltwater. Considering the placement of the carrot slice in water and salt water, students will infer that the density of salt water must be...

Inquiry in Action: Defining Density
Do heavy things always sink and light things always float? In this introductory demonstration and activity, students are introduced to the concept of density as they explore a rock and a wooden block in water.

Alex: What's the Matter: A Sinker or Floater?
Students will explore matter that sinks or floats when submerged in water and that matter is categorized as either a sinker or a floater. Students will work actively in small, cooperative learning groups as well as gather in a whole...
