Teach Engineering: Down With the Clip!

For Teachers 4th - 8th
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...

Pbs Teachers: Submarine Race Experiment

For Students Pre-K - 1st
Balance the force of gravity with the force of the expanding gasses created by mixing baking soda and vinegar. Create a soda bottle submarine that sinks to the bottom of the bathtub and then rises back to the surface.

Mocomi: Buoyancy

For Students 1st - 7th
Ever wonder why/how things float? This concept is called buoyancy. Take this interactive journey to learn and understand how and why certain materials float and others sink to the ocean floor.

Serc: Water Activity

For Teachers K - 1st
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.
