Compare the density of water to that of different liquids. Krystal Balmes and Sahil from the Brooklyn Preschool of Science make predictions about the density of water to that of honey, corn syrup, and ...

Students will be able to explain that the density of a liquid has to do with how heavy it is for the sample size. Students will also be able to explain that if a liquid is more dense than water, it ...

The particles of a solid are very close together. It melts when it changes from the solid state to the liquid state. The same mass of liquid will have slightly greater volume than the solid. As ...

It is tempting to think that some materials are always heavier than other materials. For example, someone might say that metal is heavier than air. But it depends on how much of each material there is ...

Water is so common that we take it for granted. Yet water also has very strange properties compared to most other liquids. In addition to ordinary water and water vapor, or steam, there are at least ...

People learn about a food's satiating capacity by exposure and consequently adjust their energy intake. Buffet intake depended on energy density and day of consumption of the test foods (day*energy ...

Scientists have measured the density of liquid iron -- the main component of rocky planet cores -- under conditions similar to Earth's liquid core: 1,000,000 atmospheres and 4,000 degrees Celsius.

Liquid water’s crystal structure (left) compared to that of ordinary water ice (right). Graphic: University of Cambridge If you thought ice varieties got no more interesting than crushed versus cubed, ...
