This is a great way to show students that carbon dioxide gas is heavier than air. It also helps them understand the unusual natural disaster at Lake Nyos in Africa. In 1986 a tremendous amount of carbon dioxide gas erupted from the lake, and then flo...wed down through a village, killing 1,700 people. The video is a narrative, step by step demonstration with explanations. Run time 03:59.

This video begins by defining density as a measure of how solid an object is. Then a demonstration is shown which compares the density of water, oil, and food coloring. The demonstrations are shown clearly, and the instructor carefully explains the ...results of each. Students are also shown how to make a hydrometer in this video. The video concludes by comparing the densities of many common household items.

This is the Density Song performed by science teacher Mr. Edmonds. The tune sounds quite a bit like "Popular" from the musical "Wicked". Although not all of the lyrics are provided, Mr. Edmonds holds up key words throughout the song, making it easy t...o sing along. It specifically addresses the mathematics in calculating density (mass divided by volume.) Enjoy and learn about mass,volume, and density with this catchy song. (02:41)

This program explains that volume refers to the amount of space an object envelops and that density refers to the amount of mass that is compacted in a given volume. Eureka was a series of short cartoons on physics that ran on public television in t...he 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level. Run time 04:50.

When water freezes, it expands and becomes less dense. This means that there is the same number of particles taking up more space. Since the ice cubes are less dense than the water, they float! As an ice cube melts, its volume changes, but its weigh...t is conserved (law of conservation of mass). So, the melted water has exactly the same weight as the water it displaced as an ice cube the water level stays the same! (0:44)
