Can you stay afloat? Using the information that Hayley provides and the knowledge you have of floaters and sinkers, see if you can make a sinking object float or a floating object sink in this water science experiment. Make sure you pay attention to which items are most buoyant to answer the question: Why do boats float?

About the Science

What’s it all about? Whether an object sinks or floats depends on its buoyancy. Buoyancy is an upward force caused by fluid exerted on an object immersed in that fluid. Buoyancy of an object depends on its density. In order for an object to stay afloat it must be less dense than the fluid surroun...
