Learn about the existence of an upward force on an object equal to the weight of the fluid displaced while that object is submerged in a fluid with this video. This video will introduce students to Archimedes' principle and buoyant...

Created to teach students of the 21st century, SOPHIA is bringing buoyancy straight to your fingertips. Become the commander of your own learning experiences as you take part in this brief tutorial. [1:00]

Will a grape float in oil? Will a metal nut sink in corn syrup? Watch as the ZOOM cast tests the buoyancy of a variety of liquids and objects. [4:22]

In this video segment adapted from ZOOM, the cast discovers that gas-filled bubbles act like life jackets for raisins, making them buoyant. [2:06]

Narrated animation that visually explains how the air displaced by a blimp causes a buoyant force that gives the blimp lift. (30 secs)

Join these children as they discover what happens when rising water can move objects. [1:26]

This lesson will describe how buoyant forces allow objects to float.

A nautilus' shell, when x-rayed, reveals the many chambers, which the nautilus uses to regulate buoyancy as it moves up and down in the ocean. Observe this process with this video! [1:54]

Watch kids use the scientific method to figure out why hot air can lift things. Discover how a hot air balloon works.

This video segment adapted from ZOOM offers a clever demonstration of buoyancy by showing how to pour a cup of air into a cup filled with water. [1 mim, 42 sec]
